The notes have not been and will not be registered under the Financial Instruments and Exchange Act of Japan, or the FIEA, and are subject to the Act on Special Measures Concerning Taxation of Japan, or the Special Taxation Measures Act. The notes may not be offered or sold in Japan, to any person resident in Japan, or to others for reoffering or resale directly or indirectly in Japan or to a person resident in Japan, for Japanese securities law purposes (including any corporation or other entity organized under the laws of Japan) except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the FIEA and any other applicable laws, regulations and governmental guidelines of Japan. In addition, the notes are not, as part of the distribution by the underwriters under the applicable underwriting agreement at any time, to be directly or indirectly offered or sold to, or for the benefit of, any person other than a beneficial owner that is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individualnon-resident of Japan or anon-Japanese corporation that in either case is a person having a special relationship with the issuer of the notes as described in Article 6, Paragraph (4) of the Special Taxation Measures Act, or a specially-related person of the issuer or (ii) a Japanese financial institution, designated in Article 6, Paragraph (9) of the Special Taxation Measures Act, except as specifically permitted under the Special Taxation Measures Act.

Interest payments on the notes will be subject to Japanese withholding tax unless it is established that the notes are held by or for the account of a beneficial owner that is (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individualnon-resident of Japan or anon-Japanese corporation that in either case is a specially-related person of the issuer, (ii) a Japanese financial institution designated in Article 6, Paragraph (9) of the Special Taxation Measures Act which complies with the requirement for tax exemption under that paragraph or (iii) a Japanese public corporation, financial institution or financial instruments business operator described in Article3-3, Paragraph (6) of the Special Taxation Measures Act which complies with the requirement for tax exemption under that paragraph.

Interest payments on the notes to an individual resident of Japan, to a Japanese corporation (except as described in the preceding paragraph), or to an individualnon-resident of Japan or anon-Japanese corporation that in either case is a specially-related person of the issuer will be subject to deduction in respect of Japanese income tax at a rate of 15.315% (15% on or after January 1, 2038) of the amount of such interest.

PROHIBITION OF SALES TO EEA RETAIL INVESTORS—The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area, or the EEA. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended, or MiFID II; or (ii) a customer within the meaning of Directive 2002/92/EC, as amended, or the Insurance Mediation Directive, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC, as amended, or the Prospectus Directive. Consequently no key information document required by Regulation (EU) No 1286/2014, or the PRIIPs Regulation, for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

Representation by Investor upon Distribution

By subscribing to any notes, an investor will be deemed to have represented that it is a beneficial owner who is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individualnon-resident of Japan or anon-Japanese corporation that in either case is a person having a special relationship with the issuer of the notes as described in Article 6, Paragraph (4) of the Special Taxation Measures Act or (ii) a Japanese financial institution, designated in Article 6, Paragraph (9) of the Special Taxation Measures Act.

• Certain events of bankruptcy, insolvency, reorganization or liquidation under bankruptcy, civil rehabilitation, reorganization or insolvency law of Japan shall have occurred with respect to us or an effective resolution shall have been passed by us for our winding up or dissolution.

See “Description of the Notes—Events of Default and Remedies.”

Each holder and the trustee acknowledge, consent and agree (a) for a period of 30 days from and including the date upon which the Prime Minister of Japan, or the Prime Minister, confirms that any of the measures set forth in Article126-2, Paragraph 1, Item 2 of the Deposit Insurance Act of Japan, or the Deposit Insurance Act (or any successor provision thereto), or Specified Item 2 Measures (tokutei dai nigo sochi), should be applied to us, not to initiate any action to attach any assets, the attachment of which has been prohibited by designation of the Prime Minister pursuant to Article126-16 of the Deposit Insurance Act (or any successor provision thereto) and (b) to any transfer of our assets (including shares of our subsidiaries) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article126-13 of the Deposit Insurance Act (or any successor provision thereto), including any such transfer made pursuant to the authority of the Deposit Insurance Corporation of Japan, or the DIC, to represent and manage and dispose of our assets under Article126-5 of the Deposit Insurance Act (or any successor provision thereto), and that any such transfer shall not constitute a sale or disposal of our properties or assets for the purpose of the restrictions described in “Description of the Debt Securities—Consolidation, Merger, Sale or Conveyance” in the accompanying prospectus.

Listing We have made an application to the Luxembourg Stock Exchange to list the notes on the official list of the Luxembourg Stock Exchange and for such notes to be admitted to trading on the Luxembourg Stock Exchange’s Euro MTF Market.

S-7

Global Security The notes of each series will be initially represented by one or more global certificates in definitive, fully registered form without interest coupons, or global securities. The global securities will be deposited upon issuance with the custodian for DTC and registered in the name of DTC or its nominee. Beneficial interests in the global securities may be held only through DTC (or any successor clearing system that holds global securities) and its participants, including Euroclear and Clearstream.

Beneficial interests in the global securities will be shown on, and transfers thereof will be effected only through, records maintained by the depositaries and their participants. The sole holder of the notes represented by a global security will at all times be DTC or its nominee (or a successor of DTC or its nominee), and voting and other consensual rights of holders of each series of the notes will be exercisable by beneficial owners of the notes only indirectly through the rules and procedures of the depositaries from time to time in effect. Beneficial interests in the global securities may not be exchanged for definitive notes except in the limited circumstances described under “Description of the Debt Securities—Form, Book-entry and Transfer” in the accompanying prospectus.

Use of Proceeds We intend to use the net proceeds of this offering to extend senior unsecured loans to SMBC. SMBC intends to use the proceeds of the loans for general corporate purposes.

Trustee, Paying Agent, Transfer Agent and Registrar The Bank of New York Mellon will act as the trustee, paying agent, transfer agent and registrar for each series of the notes.

Conflicts of Interest SMBC Nikko Securities America, Inc. is an affiliate of ours and, as a result, has a “conflict of interest” under Rule 5121 of the Financial Industry Regulatory Authority, Inc. (FINRA), or Rule 5121. Consequently, this offering is being conducted in compliance with the provisions of Rule 5121. Because this offering is of notes that are rated investment grade, pursuant to Rule 5121, the appointment of a “qualified independent underwriter” is not necessary. See “Underwriting (Conflicts of Interest).”

RISK FACTORS

Investing in the notes involves risks. You should consider carefully the risks relating to the notes described below, as well as the other information presented in, or incorporated by reference into, this prospectus supplement and the accompanying prospectus, before you decide whether to invest in the notes. If any of these risks actually occurs, our business, financial condition and results of operations could suffer, and the trading price and liquidity of the notes offered could decline, in which case you may lose all or part of your investment. The following does not describe all the risks of an investment in the notes. Prospective investors should consult their own financial and legal advisers about risks associated with investment in a particular series of notes and the suitability of investing in the notes in light of their particular circumstances.

This prospectus supplement and the accompanying prospectus also contain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including the risks described below, elsewhere in this prospectus supplement and in “Item 3. Key Information—Risk Factors” of our annual report on Form20-F for the fiscal year ended March 31, 2018.

Risks Related to the Notes

The notes will be structurally subordinated to indebtedness and other liabilities of our subsidiaries, including Sumitomo Mitsui Banking Corporation.

As a holding company, our assets consist primarily of equity in and loans to our subsidiaries, in particular SMBC, and our ability to make payments on the notes depends on our receipt of dividends, loan payments and other funds from such subsidiaries. If SMBC Group subsidiaries’ financial conditions materially deteriorate or under certain other conditions, we may not be able to receive such funds from our subsidiaries due to legal restrictions, including under the Banking Act of Japan, or the Banking Act, the Companies Act of Japan, or the Companies Act, and the Deposit Insurance Act or as a result of contractual obligations applicable to such subsidiaries. Claims of holders of the notes will be structurally subordinated to claims of creditors of our subsidiaries. In addition, our right to participate in any distribution of assets of any subsidiary (and thus the ability of holders of the notes to benefit as our creditors from such distribution) in bankruptcy, corporate reorganization, civil rehabilitation, liquidation or similar proceedings will be junior to creditors of that subsidiary, except to the extent that we may be recognized as a creditor of those subsidiaries in such proceedings. Claims of creditors of our subsidiaries include substantial amounts of long-term debt, deposit liabilities of SMBC and other banking subsidiaries, short-term borrowings, obligations under derivative transactions, trade payables and lease obligations. As a result, holders of the notes may receive less than full payment in the event of our bankruptcy, corporate reorganization, civil rehabilitation, liquidation or similar proceeding, even though the claims of creditors of our subsidiaries may be satisfied in full.

We expect to use the proceeds of the offering to extend senior unsecured loans to SMBC. However, we may discharge or extinguish (in whole or in part) or restructure such loans or any other loans to or investments in SMBC or any of our other subsidiaries at any time including, without limitation, to satisfy banking or other regulatory requirements, including loss absorption requirements, applicable to us in the future. For example, in April 2016, the FSA published an explanatory paper entitled “The FSA’s Approach to Introduce the TLAC Framework,” or the FSA’s Approach, which was revised in April 2018. The FSA’s Approach describes the FSA’s approach for the introduction of the Total Loss-Absorbing Capacity, or TLAC, to the framework of the Financial Stability Board, or the FSB, in Japan. Under the FSA’s Approach, the FSA plans to require bank holding companies of global systemically important banks, orG-SIBs, in Japan, which includes us, to cause any materialsub-groups that are designated as systemically important by the FSA or that are subject to TLAC requirements or similar requirements by the relevant foreign authorities to maintain a certain level of capital and debt recognized by the FSA as having loss-absorbing and recapitalization capacity, or Internal TLAC. We may restructure our loans to or investments in our material subsidiaries to meet such Internal TLAC requirements in

S-9

the future. See “Supervision and Regulation—Combined TLAC and Capital Buffer Requirements in Japan” set forth herein, and “Item 4. Information on the Company—4.B. Business Overview—Regulations in Japan—Regulations Regarding Capital Adequacy and Liquidity—Capital Adequacy Requirement” in our annual report on Form20-F for the fiscal year ended March 31, 2018, which is incorporated by reference herein. A restructuring could include changes to the legal or regulatory form of the loan or investment, changes to its ranking as a claim in the bankruptcy, corporate reorganization, civil rehabilitation, liquidation or similar proceeding of the subsidiary, changes to or addition of contractual loss absorbing mechanisms or any other changes or additions to its terms or features. Any such changes may affect our status as creditor of such subsidiary, which could materially adversely affect the value of the notes.

The notes will be subject to loss absorption if we become subject to orderly resolution measures under the Deposit Insurance Act and Japanese insolvency laws. As a result, the value of the notes could be materially adversely affected, and holders of the notes may lose all or a portion of their investment.

In November 2015, the FSB published its final TLAC standards. The final TLAC standards define certain minimum requirements for instruments and liabilities so that if aG-SIB fails, it will have sufficient loss absorbing and recapitalization capacity available in resolution. In addition, in April 2016, the FSA published the FSA’s Approach, which was revised in April 2018. For more information regarding the FSB’s final TLAC standards and the FSA’s Approach, see “Supervision and Regulation—Combined TLAC and Capital Buffer Requirements in Japan” set forth herein and “Item 4. Information on the Company—4.B. Business Overview—Regulations in Japan—Regulations Regarding Capital Adequacy and Liquidity— Capital Adequacy Requirement” in our annual report on Form20-F for the fiscal year ended March 31, 2018, which is incorporated by reference herein. We intend for the notes, due in part to their structural subordination, to qualify as TLAC when the regulations to introduce the TLAC requirements in Japan become effective. However, as of the date of this prospectus supplement, TLAC requirements have not been finalized in Japan and the FSA’s Approach is subject to change based on future discussion among international regulators. There is no assurance that such requirements as adopted in Japan will be the same as the FSB’s final TLAC standards or that the notes will qualify as TLAC under such requirements.

The notes are expected to be subject to potential losses through our liquidation pursuant to court-administered insolvency proceedings following the application of the orderly resolution powers under the Deposit Insurance Act. The Deposit Insurance Act, as amended in March 2014, provides the framework for resolving financial institutions, including financial holding companies, such as us, and operating banks. Such framework includes measures that may be applied to a financial institution prior to its failure, although there is no assurance that such measures would be applied in any given situation, and orderly resolution measures for financial institutions that have already failed or are likely to fail. Under the FSA’s Approach, the FSA has identified Single Point of Entry, or SPE, resolution, in which resolution powers are applied to thetop-level entity of a banking group by a single national resolution authority, as the preferred strategy for resolvingG-SIBs in Japan. A possible model of a resolution of JapaneseG-SIBs under the SPE resolution strategy described in the FSA’s Approach is that, if the Prime Minister recognizes that a financial institution’s liabilities exceed or are likely to exceed its assets, or that it has suspended or is likely to suspend payment of its obligations, as a result of the financial institution’s loans to, or investments or any other Internal TLAC in, its material subsidiaries that are designated as systemically important by the FSA or that are subject to TLAC requirements or similar requirements by the relevant foreign authorities becoming subject to loss absorption, and further recognizes that the failure of such financial institution may cause significant disruption in the financial markets or other financial systems in Japan, following deliberation by Japan’s Financial Crisis Response Council, the Prime Minister may confirm that Specified Item 2 Measures (tokutei dai nigo sochi), should be applied to such financial institution. Any such confirmation by the Prime Minister also triggers the point ofnon-viability clauses of Basel III Additional Tier 1 and Tier 2 instruments issued by the financial institution, causing such instruments to be written off or, if applicable, converted into equity. The failed financial institution shall also be placed under special supervision by, or if the Prime Minister so orders, under special control of, the DIC, in which case, pursuant to Article126-5 of the Deposit Insurance Act, the DIC would have broad authority to supervise or

S-10

control the failed financial institution’s business, assets and/or liabilities, including the transfer of its systemically important assets and liabilities (which we expect in the case of our orderly resolution would include the shares of SMBC and other of our material subsidiaries) to a bridge financial institution established as a subsidiary of the DIC or such other financial institution as the DIC may determine, the repayment of certain of its liabilities and ultimately the initiation of court-administered insolvency proceedings with respect to such financial institution, in each case in accordance with the Deposit Insurance Act and other relevant laws. See “Item 4. Information on the Company—4.B. Business Overview—Regulations in Japan—Regulations for Stabilizing the Financial System—Deposit Insurance System” in our annual report on Form20-F for the fiscal year ended March 31, 2018, which is incorporated by reference herein. In addition, to facilitate that transfer, the Prime Minister can designate certain assets that will be transferred to a bridge financial institution or to such other financial institution as part of our orderly resolution to be subject to a prohibition on attachment pursuant to Article126-16 of the Deposit Insurance Act.

To facilitate our orderly resolution under the Deposit Insurance Act and Japanese insolvency proceedings, each holder and the trustee acknowledge, consent and agree (a) for a period of 30 days from and including the date upon which the Prime Minister confirms that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to us, not to initiate any action to attach any assets, the attachment of which has been prohibited by designation of the Prime Minister pursuant to Article126-16 of the Deposit Insurance Act (or any successor provision thereto) and (b) to any transfer of our assets (including shares of our subsidiaries) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article126-13 of the Deposit Insurance Act (or any successor provision thereto), including any such transfer made pursuant to the authority of the DIC to represent and manage and dispose of our assets under Article126-5 of the Deposit Insurance Act (or any successor provision thereto). The above permission may be granted by a Japanese court in accordance with the Deposit Insurance Act if (i) we are under special supervision by, or under special control of, the DIC pursuant to the Deposit Insurance Act and (ii) our liabilities exceed or are likely to exceed our assets, or we have suspended or are likely to suspend payment of our obligations.

If we become subject to orderly resolution procedures under the Deposit Insurance Act, there can be no assurance that the exercise of measures available to the Prime Minister, the DIC or the Japanese courts to prevent disruption to financial markets or other financial systems in Japan would not adversely affect the rights of holders of the notes or the value of any holder’s investment in the notes. For example, if the shares of our subsidiaries are transferred to a bridge financial institution or such other financial institution as determined by the DIC, we would only be entitled to receive consideration representing the fair value of such shares, which could be significantly less than the book value of such shares. As a result, the recovery value of our residual assets in court-administered insolvency proceedings after the exercise of orderly resolution measures by the DIC may not be sufficient to fully satisfy our liabilities, including our obligations under the notes. In addition, the value of assets subject to a prohibition of attachment may decline while such prohibition is in effect, and following such period, holders will be unable to attach any assets that have been transferred to a bridge financial institution or such other financial institution as part of our orderly resolution.

The circumstances surrounding or triggering orderly resolution are unpredictable.

The occurrence of orderly resolution under the Deposit Insurance Act is inherently unpredictable and depends on a number of factors that may be beyond our control. Under the current framework, the commencement of the orderly resolution process is dependent upon, among other things, a determination by the Prime Minister, following deliberation by Japan’s Financial Crisis Response Council, regarding our viability, or the viability of one or more of our subsidiaries, and the risk that such failure may cause significant disruption in the financial markets or other financial systems in Japan. Under the FSA’s Approach, as a possible model of a resolution of JapaneseG-SIBs under the SPE resolution strategy, the application of Specified Item 2 Measures (tokutei dai nigo sochi) to us may result from, among other things, a loan that we extended to, or an investment we made in, or any other Internal TLAC of, SMBC or any of our other material subsidiaries that are designated as systemically important by the FSA or that are subject to TLAC requirements or similar requirements by the

S-11

relevant foreign authorities, being subjected to loss absorption before the failure of such subsidiary, pursuant to the terms of such loan or investment or other Internal TLAC or in accordance with applicable laws or regulations then in effect. However, according to the FSA’s Approach, the actual measures to be taken with respect to a JapaneseG-SIB shall be determined by the relevant authorities on acase-by-case basis after taking into consideration the JapaneseG-SIB’s actual condition. In addition, the application of orderly resolution measures under the Deposit Insurance Act is untested and will be subject to interpretation and application by the relevant regulatory and supervisory authorities in Japan. Moreover, it is uncertain how the relevant authorities would determine that our liabilities exceed or are likely to exceed our assets, or we have suspended or are likely to suspend payment of our obligations, which determination is required to commence an orderly resolution, and it is possible that particular circumstances that seem similar may result in different outcomes. Our creditors, including holders of the notes, may encounter difficulty in challenging the application of orderly resolution measures to us.

It may be difficult to predict when, if at all, we may become subject to orderly resolution. Accordingly, the market value of the notes may not necessarily be evaluated in a similar manner as other types of senior securities. Any indication that we are approaching circumstances that could result in us becoming subject to orderly resolution can be expected to have an adverse effect on the market price and liquidity of the notes.

The notes are unsecured obligations.

The notes are unsecured obligations and repayment of the notes may be compromised if:

• we enter into bankruptcy, corporate reorganization, civil rehabilitation, liquidation or similar proceeding;

• we default in payment of any existing or future indebtedness; or

• any of our existing or future indebtedness is accelerated.

If any of these events occurs then our assets may be insufficient to pay amounts due on the notes.

The Indenture and the notes do not restrict our ability or the ability of our subsidiaries to pledge, dispose or securitize our assets, pay dividends, incur indebtedness or issue or repurchase securities, and provide holders with limited protection in the event of a change in control and other actions we may take that could adversely impact your investment in the notes.

The Indenture and the notes do not contain any financial covenants or restrictions on our ability, or the ability of our subsidiaries, to pledge assets to secure any indebtedness, securitize assets, pay dividends on our shares of common stock, incur or assume additional indebtedness or other liabilities or repurchase our outstanding securities. These or other actions by us could adversely affect our ability to pay amounts due on the notes. In addition, the Indenture and the notes do not contain any covenants or other provisions that afford more than limited protection to holders of the notes in the event of a change in control.

There is no prior market for the notes and, if a market develops, it may not be liquid.

The notes are new securities which may not be widely distributed and for which there is currently no active trading market. Although we have made an application to the Luxembourg Stock Exchange to list the notes on the official list of the Luxembourg Stock Exchange and for such notes to be admitted to trading on the Luxembourg Stock Exchange’s Euro MTF Market, there can be no assurance that any liquid market for the notes will ever develop or be maintained. The underwriters have advised us that they currently intend to make a market in the notes that they distribute. However, the underwriters have no obligation to make a market in the notes and they may stop at any time. Furthermore, there can be no assurance as to the liquidity of any market that may

S-12

develop for the notes or the prices at which you will be able to sell your notes, if at all. Future trading prices of the notes will depend on many factors, including:

• prevailing interest rates;

• our financial condition and results of operations;

• the then-current ratings assigned to the notes;

• the market for similar securities; and

• general economic conditions.

Any trading market that develops would be affected by many factors independent of and in addition to the foregoing, including the time remaining to the maturity of the notes; the outstanding amount of the notes; and the level, direction and volatility of market interest rates generally.

In addition, in the event that our obligations in connection with maintaining the listing of the notes on the Luxembourg Stock Exchange becomes unduly burdensome, we may be entitled to, and may decide to, delist the notes from such securities exchange and seek an alternate listing for the notes on another securities exchange.

The ratings of the notes may change after issuance of the notes, and those changes may have an adverse effect on the market prices and liquidity of the notes.

The notes are expected to receive a credit rating from one or more credit rating agencies. Such ratings are limited in scope, and do not address all material risks relating to an investment in the notes, but reflect only the view of each rating agency at the time the rating is issued. There is no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. Ratings may be affected by a number of factors which can change over time, including the credit rating agency’s assessment of: the issuer’s strategy and management’s capability; the issuer’s financial condition including in respect of capital, funding and liquidity; competitive and economic conditions in the issuer’s key markets; the level of political support for the industries in which the issuer operates; and legal and regulatory frameworks affecting the issuer’s legal structure, business activities and the rights of its creditors. The credit rating agencies may also revise the ratings methodologies applicable to issuers within a particular industry, or political or economic region. If credit rating agencies perceive there to be adverse changes in the factors affecting an issuer’s credit rating, including by virtue of changes to applicable ratings methodologies, the credit rating agencies may downgrade, suspend or withdraw the ratings assigned to an issuer and/or its securities.

In particular, Moody’s Investors Service, S&P Global Ratings and Fitch Ratings each published revised methodologies applicable to bank ratings (including us) during 2015. Further revisions to ratings methodologies and actions on our ratings or ratings of our subsidiaries (including but not limited to SMBC) by the credit rating agencies may occur in the future, which may result in downgrading of certain ratings.

A downgrade or potential downgrade in these ratings or the assignment of new ratings that are lower than existing ratings could reduce the number of potential investors in the notes and adversely affect the prices and liquidity of the notes. A security rating is not a recommendation to buy, sell or hold the notes and may be subject to suspension, reduction or withdrawal at any time by the assigning rating agency.

There are risks that LIBOR may be administered differently or discontinued in the future, which may adversely affect the value and marketability of and return on the floating rate notes.

LIBOR is the subject of ongoing national and international regulatory reforms and, following the implementation of any such potential reforms, the manner of its administration may change, with the result that it

S-13

may perform differently than in the past, it could be eliminated entirely or a substitute or alternative benchmark could be established, or there could be other consequences that cannot be predicted. On July 27, 2017, the United Kingdom Financial Conduct Authority announced that it will no longer persuade or compel banks to submit rates for the calculation of the LIBOR benchmark after 2021, indicating that the continuation of LIBOR on the current basis cannot and will not be guaranteed after 2021. The potential changes in the manner of administration or the potential elimination of LIBOR could require adjustments to the terms of the floating rate notes or result in other consequences, such as discrepancies between the interest rates calculated as described herein and those based on any substitute or alternative benchmark that may become the market standard by or after 2021. Any such consequence could have an adverse effect on the value and marketability of and return on the floating rate notes.

Foreign Account Tax Compliance Act

Provisions of U.S. tax law commonly referred to as the Foreign Account Tax Compliance Act, or FATCA, impose a 30% withholding tax on certain U.S. source payments made to a foreign financial institution (such as ourselves, certain of our subsidiaries or a financial intermediary through which an investor may hold notes), unless the financial institution is a “participating foreign financial institution,” or a PFFI, or otherwise exempt from FATCA. A PFFI is a foreign financial institution that has entered into an agreement with the U.S. Treasury Department, or a PFFI agreement, pursuant to which it agrees to perform specified due diligence, reporting and withholding functions. Specifically, under its PFFI agreement, a PFFI is required to obtain and report to the U.S. Internal Revenue Service, or the IRS, certain information with respect to financial accounts held by U.S. persons or U.S.-owned foreign entities and may be required to withhold 30% from “foreign passthru payments” (which term is not yet defined) that it makes to foreign financial institutions that are not PFFIs or otherwise exempt from FATCA and certain other persons who fail to provide requested information, if such payments are made on or after the later of January 1, 2019 and the date of publication of final Treasury regulations defining the term “foreign passthru payments.” No such withholding would apply to any payments made onnon-U.S. debt obligations (such as the notes) that are issued before (and not materially modified after) the date that is six months after the date on which final regulations defining the term “foreign passthru payments” are published. The United States and Japan have entered into an intergovernmental agreement to facilitate the implementation of FATCA pursuant to which Japanese financial institutions (such as ourselves and certain of our subsidiaries) are directed by the Japanese authorities to register with the IRS and fulfill obligations consistent with those required under a PFFI agreement. We have registered with the IRS as a PFFI. The United States has also entered into intergovernmental agreements with other jurisdictions. These intergovernmental agreements (including the intergovernmental agreement with Japan) do not address how the United States and the relevant jurisdictions (including Japan) will address “foreign passthru payments” or whether withholding on such payments will be required by financial institutions that are subject to an intergovernmental agreement.

In the event that any amount of withholding is required from a payment on a note under FATCA or any intergovernmental agreement entered into with respect thereto, or any law, regulation or guidance implementing FATCA or such intergovernmental agreement, no additional amounts will be payable by us and withheld amounts will be treated as paid for all purposes under the notes.

S-14

USE OF PROCEEDS

We estimate that the net proceeds (after deducting underwriting commissions and estimated offering expenses) from the sale of the notes will be approximately $1,991 million. We intend to use the net proceeds of this offering to extend senior unsecured loans to SMBC. SMBC intends to use the proceeds of the loans for general corporate purposes.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our ratio of earnings to fixed charges, presented in accordance with IFRS, for each of the periods indicated. You should read this table in conjunction with the consolidated financial statements and notes incorporated by reference herein.

	Fiscal year ended March 31,
	2014		2015		2016		2017		2018
Ratio of earnings to fixed charges
Excluding interest on deposits		5.32		4.67		5.03		3.51		3.49
Including interest on deposits		3.87		3.33		3.43		2.41		2.30

In calculating the ratio of earnings to fixed charges, we used the following definitions:

The term “fixed charges” means the sum of the following: (a) interest expensed and capitalized, (b) amortized premiums, discounts and capitalized expenses related to indebtedness, (c) an estimate of the interest within rental expense and (d) preference security dividend requirements of consolidated subsidiaries.

The term “earnings” is the amount resulting from adding and subtracting the following items. Add the following:(a) pre-tax income from continuing operations before adjustment for income or loss from equity investees, (b) fixed charges, (c) amortization of capitalized interest, (d) distributed income of equity investees and (e) our share ofpre-tax losses of equity investees for which charges arising from guarantees are included in fixed charges. From the total of the added items, subtract the following: (a) interest capitalized, (b) preference security dividend requirements of consolidated subsidiaries and (c) thenon-controlling interest inpre-tax income of subsidiaries that have not incurred fixed charges. Equity investees are investments that we account for using the equity method of accounting.

(4) Total credit cost = Provision for reserve for possible loan losses +Write-off of loans + Losses on sales of delinquent loans – Gains on reversal of reserve for possible loan losses – Recoveries ofwritten-off claims.

(5) Interest spread is the difference between the rate of the interest earned on average interest-earning assets and the rate of interest paid on average interest-bearing liabilities.

(6) Overhead ratio is SMBC’s expenses divided by gross banking profit.

Risk-weighted assets		70,683.5			63,540.3
The amount of total minimum capital requirements(1)		5,654.7			5,083.2

(1) The amount of total minimum capital requirements is calculated by multiplying RWA by 8%.

We have been managing our regulatory capital ratios by focusing on controlling our RWA while increasing profitability. We estimate that our Common Equity Tier 1 risk-weighted capital ratio was 12.2% as of March 31, 2017, based on the definition as of March 31, 2019, or a fully-loaded basis. The definition applicable as of March 31, 2018 for calculation of Common Equity Tier 1 capital is identical to the definition as of March 31, 2019.

SMBC’s Bond Portfolio

SMBC’s bond portfolio is principally held for ALM purposes, with a small number of securities being held for inventory purposes for sales to customers. Most of SMBC’s bond portfolio is comprised of fixed-rate Japanese and local government bonds and high quality corporate bonds denominated in yen. On anon-consolidated basis, the approximate average duration of SMBC’syen-denominated bond portfolio, including Japanese government bonds, or JGBs, but excluding private placement bonds, bondsheld-to-maturity and bonds for which fair value hedge accounting is applied, was 2.9 years and 2.3 years as of March 31, 2017 and 2018, respectively. Bonds are also held to enhance liquidity, and, when needed, they can be used as collateral for call money or other money market funding or short-term borrowing from the Bank of Japan, or the BOJ. Sales of bonds are made from time to time in order to recognize discretionary gains. SMBC’s Treasury Department actively monitors the interest rate and maturity profile of its bond portfolio as part of our overall risk management.

SUPERVISION AND REGULATION

Combined TLAC and Capital Buffer Requirements in Japan

In November 2015, as part of its agenda to address risks arising fromG-SIBs, the FSB published its final TLAC standards. The final TLAC standards define certain minimum requirements for instruments and liabilities so that if aG-SIB fails, it will have sufficient loss-absorbing and recapitalization capacity available to ensure that it can be resolved in an orderly manner which minimizes potential impact on financial stability, maintains the continuity of critical functions and avoids exposing public funds to loss. In addition, in April 2016, the FSA published the FSA’s Approach, which was revised in April 2018. The FSA’s Approach describes the FSA’s approach for the introduction of TLAC requirements in Japan, although it remains subject to change based on future discussions among international regulators. According to the FSA’s Approach, the preferred resolution strategy forG-SIBs in Japan is SPE resolution, in which resolution powers are applied to thetop-level entity of a banking group by a single national resolution authority, although the actual measures to be taken will be determined on acase-by-case basis considering the actual condition of the relevant JapaneseG-SIB in crisis. To implement this SPE resolution strategy effectively, the FSA plans to require bank holding companies of JapaneseG-SIBs, which will be the resolution entities, to (i) meet the minimum external TLAC requirements provided under the FSB’s TLAC standard (being at least 16% of their RWA, starting from March 31, 2019 and at least 18% of their RWA starting from March 31, 2022 as well as at least 6% of their Basel III leverage ratio denominator starting from March 31, 2019 and at least 6.75% starting from March 31, 2022), and (ii) cause their material subsidiaries that are designated as systemically important by the FSA or that are subject to TLAC requirements or similar requirements by the relevant foreign authorities, including but not limited to certain materialsub-groups as provided in the FSB’s TLAC standard, to maintain a certain level of capital and debt recognized by the FSA as internal TLAC, in order that losses incurred at the materialsub-group will be absorbed by the bank holding company through such internal TLAC with the involvement of the FSA. In addition, according to the FSA’s Approach, JapaneseG-SIBs are expected to be allowed to count the Japan’s deposit insurance fund reserves in an amount equivalent to 2.5% of their RWA from March 31, 2019 and 3.5% of their RWA from March 31, 2022 as external TLAC. Under the FSA’s Approach, the FSA plans to apply the TLAC requirements for JapaneseG-SIBs from March 31, 2019.

For a possible model of a resolution of JapaneseG-SIBs, see “Risk Factors—Risks Related to the Notes—The notes will be subject to loss absorption if we become subject to orderly resolution measures under the Deposit Insurance Act and Japanese insolvency laws. As a result, the value of the notes could be materially adversely affected, and holders of the notes may lose all or a portion of their investment.”

Combining the proposed thresholds described in the FSA’s Approach and the FSB’s framework as well as the thresholds for capital buffers under Basel III rules, anticipated minimum TLAC requirements and capital buffer requirements (excluding the countercyclical buffer) as implemented in Japan and applicable to us are effectively:

• at least 17% of the relevant resolution group’s RWA starting in 2019; and

• at least 18% of RWA starting in 2022,

in each case, after taking into account:

(1) minimum TLAC requirement of at least 16% of RWA starting in 2019 and at least 18% of RWA starting in 2022;

(2) an additional 1% of RWA for theG-SIB capital surcharge (based on our status as a bucket 1G-SIB) which will be fully implemented from 2019;

(3) an additional 2.5% of RWA for the capital conservation buffer which will be fully implemented from 2019; and

(4) an expected treatment of 2.5% of RWA from 2019 and 3.5% of RWA from 2022 as TLAC, resulting from our access to Japan’s deposit insurance fund reserves.

The above does not reflect the Basel III countercyclical buffer requirement, which is calculated based on the weighted average of the buffer requirement in effect in each of the jurisdictions to which the relevantG-SIB has credit exposure. Under Basel III, the countercyclical buffer requirement will be fully implemented from 2019.

In addition, under the finalized Basel III reforms,G-SIBs are required to meet a leverage ratio buffer, which will take the form of a Tier 1 capital buffer set at 50% of the applicableG-SIB capital surcharge. The leverage ratio buffer requirement forG-SIBs will take effect from January 1, 2022.

DESCRIPTION OF THE NOTES

The following description of the notes supplements and, to the extent inconsistent therewith, replaces the description of the general terms and provisions of our senior debt securities set forth in the accompanying prospectus under the heading “Description of the Debt Securities.” It is important for you to consider the information contained in this prospectus supplement and in the accompanying prospectus and any applicable pricing term sheet in making your investment decision with respect to the notes. Whenever a defined term is referred to but not defined in this section, the definition of that term is contained in the accompanying prospectus or in the Indenture.

General

The notes will constitute senior debt securities to be issued under a senior indenture between us and The Bank of New York Mellon, as trustee, dated as of March 9, 2016, as amended or supplemented from time to time, or the Indenture. The Indenture is qualified under the U.S. Trust Indenture Act of 1939, as amended. The Indenture is more fully described in the accompanying prospectus. Copies of the Indenture and any amendments or supplements thereto will be available at the offices of the trustee.

We will issue the notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The notes of each series will be represented by one or more registered notes in global form without coupons deposited with a custodian and registered in the name of DTC or its nominee, in each case for credit to the accounts of direct and indirect participants, including Euroclear and Clearstream. In certain circumstances, the notes may be represented by definitive notes in certificated form. See “Description of the Debt Securities—Form, Book-entry and Transfer” in the accompanying prospectus.

The notes will not be redeemable prior to maturity, except as set forth below under “—Redemption for Taxation Reasons,” and will not be subject to any sinking fund.

In this section, the term “business day” means any day which is not a day on which banking institutions in The City of New York, London or Tokyo are authorized or required by law, regulation or executive order to close.

Each series of notes will constitute our direct, unconditional, unsecured and unsubordinated general obligations and will at all times rankpari passu without any preference among themselves and with all our other unsecured obligations, other than our subordinated obligations and except for statutorily preferred obligations.

We are a holding company and conduct substantially all of our operations through our subsidiaries. As a result, claims of holders of the notes will be structurally subordinated to claims of creditors of our subsidiaries. In addition, our right to participate in any distribution of assets of any subsidiary (and thus the ability of holders of the notes to benefit as our creditors from such distribution) in bankruptcy, corporate reorganization, civil rehabilitation, liquidation or similar proceedings will be junior to creditors of that subsidiary, except to the extent that we may be recognized as a creditor of those subsidiaries. In addition, various statutes and regulations may restrict our subsidiaries from paying dividends or making loans or advances to us, including the Banking Act, the Companies Act and the Deposit Insurance Act. The restrictions could prevent our subsidiaries from paying the cash to us that we need in order to make payments under the notes. See “Risk Factors—Risks Related to the Notes—The notes will be structurally subordinated to indebtedness and other liabilities of our subsidiaries, including Sumitomo Mitsui Banking Corporation.”

Principal, Maturity and Interest for the Fixed Rate Notes

We expect to issue one or more series of fixed rate notes with the initial aggregate principal amount(s) and maturity date(s) set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering.” Principal in respect of the fixed rate notes will be repaid at maturity at a price of 100% of the principal amount.

S-29

Interest on the fixed rate notes of each series will accrue at the rate per annum, and from the date, set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering.” We will pay interest on the fixed rate notes of each series semiannually in arrears on the dates set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering,” to the persons in whose names the fixed rate notes are registered as of the close of business on the fifteenth day before the due date for payment (whether or not a business day). Interest on the fixed rate notes will be paid to but excluding the relevant interest payment date. We will compute interest on the fixed rate notes on the basis of a360-day year consisting of twelve30-day months. We will pay the principal of and interest on the fixed rate notes in U.S. dollars or in such other coin or currency of the United States as at the time of payment is legal tender for the payment of public and private debts.

If any payment is due on the fixed rate notes on a day that is not a business day, we will make payment on the date that is the next succeeding business day. Payments postponed to the next succeeding business day in this situation will be treated as if they were made on the original due date. Postponement of this kind will not result in a default under the notes, and no interest will accrue on the postponed amount from the original due date to the next succeeding business day.

All payments in respect of the fixed rate notes will be subject in all cases to any applicable fiscal laws or other laws and regulations, and, except as described in “Description of the Debt Securities—Taxation and Additional Amounts” in the accompanying prospectus, no additional amounts will be payable as a result of the withholding or deduction of any taxes or duties of whatever nature imposed or levied as a result of such laws or regulations.

Principal, Maturity and Interest for the Floating Rate Notes

We expect to issue one or more series of floating rate notes with the initial aggregate principal amount(s) and maturity date(s) set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering.” Principal in respect of the floating rate notes will be repaid at maturity at a price of 100% of the principal amount.

Interest on the floating rate notes of each series will accrue at the floating rate per annum, reset quarterly, equal to the three-month U.S. dollar LIBOR plus the spread set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering.” We will pay interest on the floating rate notes of each series quarterly in arrears on the dates (each an “interest payment date”) set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering,” to the persons in whose names the floating rate notes are registered as of the close of business on the fifteenth day before the due date for payment on the floating rate notes (whether or not a business day).

We will compute interest on the floating rate notes on the basis of the actual number of days in an interest period and a360-day year. An “interest period” is the period from and including the immediately preceding interest payment date (after any adjustments to make such date a business day, as described below) to but excluding the relevant interest payment date (after any adjustments to make such date a business day, as described below). The first interest period will begin on and include the date set forth in the applicable pricing term sheet as the settlement date and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering” and will end on but exclude the first interest payment date of the floating rate notes.

We will pay the principal of and interest on the floating rate notes in U.S. dollars or in such other coin or currency of the United States as at the time of payment is legal tender for the payment of public and private debts.

S-30

If any interest payment date (other than the maturity date) of the floating rate notes would fall on a day that is not a business day, that interest payment date will be adjusted to the day that is the next succeeding business day, unless such business day is in the next succeeding month, in which case such interest payment date will be the immediately preceding business day.

If the maturity date for the floating rate notes is not a business day, the payment of interest and principal in respect of the floating rate notes will be made on the next succeeding day that is a business day, and no interest on such payment shall accrue for the period from and after the original maturity date.

All payments in respect of the floating rate notes will be subject in all cases to any applicable fiscal laws or other laws and regulations, and, except as described in “Description of the Debt Securities—Taxation and Additional Amounts” in the accompanying prospectus, no additional amounts will be payable as a result of the withholding or deduction of any taxes or duties of whatever nature imposed or levied as a result of such laws or regulations.

Determination of Floating Interest Rate

So long as any floating rate notes remain outstanding, we will maintain a calculation agent for calculating the interest rates on the floating rate notes. We have initially appointed The Bank of New York Mellon to act as the calculation agent.

The calculation agent will reset the rate of interest on the floating rate notes of each series for each interest period on the first day of each interest period. (Each such first day of an interest period is also referred to as an “interest reset date” with respect to such interest period.) The interest rate set for the floating rate notes of each series on a particular interest reset date will remain in effect during the interest period commencing on such interest reset date.

The calculation agent will determine the applicable interest rate and interest payable on the floating rate notes of each series for any interest period on the second London business day immediately preceding the interest reset date for that period, or an interest determination date. The term “London business day” means any day that is not a day on which banking institutions in London are authorized or required by law, regulation or executive order to close.

The calculation agent will calculate the interest payable on the floating rate notes of each series for any interest period by multiplying the principal amount of the floating rate notes of each series by an interest factor, which will equal the applicable interest rate for the interest period multiplied by a fraction, the numerator of which is the actual number of days in such interest period and the denominator of which is 360.

The calculation agent will determine LIBOR for any interest period according to the following provisions:

• LIBOR will equal the London interbank offered rate for three-month deposits in U.S. dollars appearing on the display page designated as the Reuters Screen LIBOR01 Page (or such other page as may replace that page on that service (or any successor service) or such other service as may be nominated by ICE Benchmark Administration Limited, or ICE, or its successor, or such other entity assuming the responsibility of ICE or its successor in the event ICE or its successor no longer does so, as the successor service, for the purpose of displaying comparable rates to LIBOR for U.S. dollar deposits), as determined by the calculation agent, as at 11:00 a.m., London time, on the interest determination date.

• If LIBOR cannot be determined in this manner, the calculation agent will (i) request the principal London office of each of four major banks selected by the calculation agent in the London interbank market to provide a quotation of the rate at which deposits in U.S. dollars are offered by it to prime banks in the London interbank market for a three-month period commencing on the relevant interest reset date and in a principal amount that in the judgment of the calculation agent is representative for a

S-31

single transaction in U.S. dollars in such market at approximately 11:00 a.m., London time, on the interest determination date, and (ii) determine LIBOR as the arithmetic mean of the quotations provided in response to such requests.

• If fewer than two such quotations are provided, the calculation agent will determine LIBOR as the arithmetic mean of the rates quoted by at least two major banks in New York City selected by the calculation agent at approximately 11:00 a.m., New York City time, on the interest determination date for three-month loans in U.S. dollars commencing on the relevant interest reset date to leading European banks in a principal amount that in the judgment of the calculation agent is representative for a single transaction in U.S. dollars in such market at such time.

• If the calculation agent is unable to determine LIBOR as described above in relation to any interest period, LIBOR will be the same as for the immediately preceding interest period.

• The interest rate payable on the floating rate notes will not be higher than the maximum rate permitted by Japanese law or by New York state law as modified by U.S. law of general application. The interest rate for floating rate notes will not be lower than zero.

The calculation agent will provide the interest rate for the current interest period and the amount of interest to be paid for such interest period to us, the trustee, DTC and any paying agent as soon as practicable upon determination. The calculations of the calculation agent will, in the absence of negligence, bad faith or manifest error, be conclusive for all purposes and binding on us, the calculation agent, the paying agent, the trustee and the holders of the floating rate notes.

All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with fiveone-millionths of a percentage point being rounded upwards (e.g., 9.876545% (or 0.09876545) being rounded to 9.87655% (or 0.0987655)), and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (withone-half cent being rounded upwards).

Redemption for Taxation Reasons

The notes of each series may be redeemed at our option, in whole, but not in part, at any time, subject to prior confirmation of the FSA (if such confirmation is required under applicable Japanese laws or regulations then in effect), on giving not less than thirty (30) nor more than sixty (60) days’ notice of redemption to the holders (which notice shall be irrevocable and shall conform to all requirements with respect to such notice as set forth in the Indenture) at a redemption price equal to 100% of the principal amount of such notes together with accrued and unpaid interest to (but excluding) the date fixed for redemption and any additional amounts thereon, if we have been or will become obliged to pay additional amounts with respect to such series as described in “Description of the Debt Securities—Taxation and Additional Amounts” in the accompanying prospectus as a result of any change in, or amendment to, the laws or regulations of Japan or any political subdivision or any authority thereof or therein having power to tax, or any change in application or official interpretation of such laws or regulations, which change or amendment becomes effective on or after the original issuance date of the notes of such series and such obligation cannot be avoided by the taking of reasonable measures available to us; provided, that no such notice of redemption shall be given sooner than ninety (90) days prior to the earliest date on which we would be obliged to pay such additional amounts were a payment then due in respect of such notes. Prior to the publication of any notice of redemption pursuant to this paragraph, we shall deliver to the trustee a certificate signed by an authorized officer stating that the conditions precedent to our right to so redeem have been fulfilled and an opinion of independent legal or tax advisor of recognized standing to the effect that we have become or will be obliged to pay such additional amounts as a result of such change or amendment.

Events of Default and Remedies

The Indenture will provide holders with certain remedies if we fail to perform specific obligations, such as making payments on the notes, or if we become subject to certain bankruptcy or insolvency events. Holders should review the Indenture and understand what constitutes an event of default and what does not.

S-32

An event of default with respect to the notes of a series will be defined under the Indenture as any one or more of the following events having occurred and continuing to exist:

• Default shall be made for more than 15 days in the payment of principal and premium, if any, and for more than 30 days in the payment of interest in respect of any of the notes of such series;

• We shall have defaulted in the performance or observance of any covenant, condition or provision contained in the notes of such series or in the Indenture in respect of the notes of such series for a period of 90 days after written notification requesting such default to be remedied by us shall first have been given to us by the trustee or holders of at least 25% in principal amount of the then outstanding notes of such series; or

• Except for the purposes of or pursuant to a consolidation, amalgamation, merger or reconstruction under which the continuing corporation or other person, or the corporation or other person formed as a result thereof, effectively assumes our entire obligations under the Indenture in relation to the notes of such series: (a) a decree or order by any court having jurisdiction shall have been issued adjudging us bankrupt or insolvent, or approving a petition seeking our reorganization or liquidation under bankruptcy, civil rehabilitation, reorganization or insolvency law of Japan, and such decree or order shall have continued undischarged and unstayed for a period of 90 days, or a final andnon-appealable order of a court of competent jurisdiction shall have been made for our winding up or dissolution or (b) we shall have initiated or consented to proceedings relating to ourselves under bankruptcy, civil rehabilitation, reorganization or insolvency law of Japan, or an effective resolution shall have been passed by us for our winding up or dissolution.

Each holder and the trustee acknowledge, consent and agree (a) for a period of 30 days from and including the date upon which the Prime Minister confirms that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to us, not to initiate any action to attach any assets, the attachment of which has been prohibited by designation of the Prime Minister pursuant to Article126-16 of the Deposit Insurance Act (or any successor provision thereto) and (b) to any transfer of our assets (including shares of our subsidiaries) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article126-13 of the Deposit Insurance Act (or any successor provision thereto), including any such transfer made pursuant to the authority of the DIC to represent and manage and dispose of our assets under Article126-5 of the Deposit Insurance Act (or any successor provision thereto), and that any such transfer shall not constitute a sale or disposal of our properties or assets for the purpose of the restrictions described in “Description of the Debt Securities—Consolidation, Merger, Sale or Conveyance” in the accompanying prospectus. See “Risk Factors—Risks Related to the Notes—The notes will be subject to loss absorption if we become subject to orderly resolution measures under the Deposit Insurance Act and Japanese insolvency laws. As a result, the value of the notes could be materially adversely affected, and holders of the notes may lose all or a portion of their investment.”

We shall, as soon as practicable after the Prime Minister has confirmed that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to us or a Japanese court has publicly announced that it has granted permission to a transfer of our assets (including shares of our subsidiaries) or liabilities, or any portions thereof, in accordance with Article126-13 of the Deposit Insurance Act (or any successor provision thereto), deliver a written notice of such event to the trustee and to the holders of the notes through DTC. Any failure or delay by us to provide such written notice shall not change or delay the effect of the acknowledgement, consent and agreement described in the preceding paragraph.

No Rights to Set Off by Holders

Subject to applicable law, each holder of the notes, by acceptance of any interest in the notes, agrees that it will not, and waives its right to, exercise, claim or plead any right of set off, compensation or retention in respect of any amount owed to it by us arising under, or in connection with, the notes or the Indenture.

S-33

The Trustee

The Bank of New York Mellon will be the trustee for the notes. The trustee may, subject to certain conditions, act as trustee for other securities issued by us or by our affiliates.

Paying Agent, Transfer Agent, Registrar and Calculation Agent

The Bank of New York Mellon will initially act as paying agent, transfer agent and registrar for each series of the notes and as calculation agent for the floating rate notes (if applicable). We may change the paying agent, calculation agent (if applicable), transfer agent or registrar without prior notice to holders of the notes, and we or any of our subsidiaries may act as paying agent, calculation agent (if applicable), transfer agent or registrar.

Governing Law

The notes will be, and the Indenture is, governed by and construed in accordance with the laws of the State of New York.

S-34

TAXATION

Japanese Taxation

The following is a general description of certain aspects of Japanese taxation applicable to the notes. It does not purport to be a comprehensive description of the tax aspects of the notes. Prospective purchasers should note that, although the general tax information on Japanese taxation is described hereunder for convenience, the statements below are general in nature and not exhaustive.

Prospective purchasers are advised to consult their own legal, tax, accountancy or other professional advisers in order to ascertain their particular circumstances regarding taxation. The statements below are based on current tax laws and regulations in Japan and current income tax treaties executed by Japan all as in effect on the date of this prospectus supplement and all of which are subject to change or differing interpretations (possibly with retroactive effect). Neither such statements nor any other statements in this document are to be regarded as advice on the tax position of any beneficial owner of the notes or any person purchasing, selling or otherwise dealing in the notes or any tax implication arising from the purchase, sale or other dealings in respect of the notes.

The Notes

The notes do not fall under the concept ofso-called “taxable linked bonds” as described in Article 6, Paragraph (4) of the Special Taxation Measures Act, i.e., bonds of which the amount of interest is to be calculated by reference to certain indexes (as prescribed by the Cabinet Order No. 43 of 1957, as amended, or the Cabinet Order, under the Special Taxation Measures Act) relating to the issuer of the notes or a specially-related person of the issuer.

Representation by Investor upon Distribution

By subscribing to the notes, an investor will be deemed to have represented that it is a beneficial owner that is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individualnon-resident of Japan or anon-Japanese corporation that in either case is a specially-related person of the issuer or (ii) a Designated Financial Institution, as defined below. The notes are not as part of the distribution by the underwriters under the applicable underwriting agreement at any time to be directly or indirectly offered or sold in Japan or to, or for the benefit of, any person other than a beneficial owner that is described in (i) or (ii) above, except as specifically permitted under the Special Taxation Measures Act.

Interest Payments on Notes and Redemption Gain

The following description of Japanese taxation (limited to national taxes) applies exclusively to interest on the notes and the redemption gain, meaning any difference between the acquisition price of the interest-bearing notes of the holder and the amount which the holder receives upon redemption of such interest-bearing notes, or the Redemption Gain, where such notes are issued outside Japan and payable outside Japan. In addition, the following description assumes that only global notes are issued for the notes, and no definitive notes and coupons that are independently traded are issued, in which case different tax consequences may apply. It is not intended to be exhaustive and prospective purchasers are recommended to consult their tax advisers as to their exact tax position.

1.Non-resident Investors

If the recipient of interest on the notes or of the Redemption Gain with respect to interest-bearing notes is an individualnon-resident of Japan or anon-Japanese corporation for Japanese tax purposes, as described below, the Japanese tax consequences on such individualnon-resident of Japan ornon-Japanese corporation are

S-35

significantly different depending upon whether such individualnon-resident of Japan ornon-Japanese corporation is a specially-related person of the issuer. Most importantly, if such individualnon-resident of Japan ornon-Japanese corporation is a specially-related person of the issuer, income tax at the rate of 15.315% of the amount of such interest will be withheld by the issuer of the notes under Japanese tax law.

1.1. Interest

(1) If the recipient of interest on the notes is an individualnon-resident of Japan or anon-Japanese corporation having no permanent establishment within Japan or having a permanent establishment within Japan but where the receipt of the interest on the notes is not attributable to the business of such individualnon-resident of Japan ornon-Japanese corporation carried on within Japan through such permanent establishment, no Japanese income tax or corporate tax is payable with respect to such interest whether by way of withholding or otherwise, if certain requirements are complied with, inter alia:

(i) if the relevant notes are held through certain participants in an international clearing organization such as DTC or certain financial intermediaries prescribed by the Special Taxation Measures Act and the Cabinet Order (each such participant or financial intermediary, a Participant), the requirement that such recipient provide, at the time of entrusting a Participant with the custody of the relevant notes, certain information prescribed by the Cabinet Order together with the Special Taxation Measures Act and the ministerial ordinance and other regulations thereunder, or the Law, to enable the Participant to establish that the recipient is exempt from the requirement for Japanese tax to be withheld or deducted, or the Interest Recipient Information, and advise the Participant if such individualnon-resident of Japan ornon-Japanese corporation ceases to be so exempted (including the case where it became a specially-related person of the issuer), and that the issuer of the notes prepare and file a certain confirmation prescribed by the Law, or the Interest Recipient Confirmation, in a timely manner based upon the Interest Recipient Information communicated through the Participant and the relevant interregional clearing organization; and

(ii) if the relevant notes are not held by a Participant, the requirement to submit to the relevant paying agent a written application for tax exemption (hikazei tekiyo shinkokusho), or the Written Application for Tax Exemption, together with certain documentary evidence, and that the issuer of the notes file the Written Application for Tax Exemption so received with the competent local tax office in a timely manner.

Failure to comply with such requirements described above (including the case where the Interest Recipient Information is not duly communicated as required under the Law) will result in the withholding by the issuer of the notes of income tax at the rate of 15.315% of the amount of such interest.

(2) If the recipient of interest on the notes is an individualnon-resident of Japan or anon-Japanese corporation having a permanent establishment within Japan and the receipt of interest is attributable to the business of such individualnon-resident of Japan ornon-Japanese corporation carried on within Japan through such permanent establishment, such interest will not be subject to a 15.315% withholding tax by the issuer of the notes, if the requirements concerning the Interest Recipient Information and the Interest Recipient Confirmation or the Written Application for Tax Exemption as set out in paragraph 1.1(1) above are complied with. Failure to do so will result in the withholding by the issuer of the notes of income tax at the rate of 15.315% of the amount of such interest. The amount of such interest will be subject to regular income tax or corporate tax, as appropriate.

(3) Notwithstanding paragraphs 1.1(1) and (2), if an individualnon-resident of Japan or anon-Japanese corporation mentioned above is a person who has a special relationship with the issuer of the notes (that is, in general terms, a person who directly or indirectly controls or is directly or indirectly controlled by, or is under direct or indirect common control with, the issuer of the notes) within the meaning prescribed by the Cabinet Order under Article 6, Paragraph (4) of the Special Taxation Measures Act (such person is referred to as a specially-related person of the issuer) as of the beginning of the fiscal year of the issuer of the notes in which the relevant interest payment date falls, the exemption from Japanese withholding tax on interest mentioned above will not apply, and income tax at the rate of 15.315% of the amount of such interest will be withheld by the issuer

S-36

of the notes. If such individualnon-resident of Japan ornon-Japanese corporation has a permanent establishment within Japan, regular income tax or corporate tax, as appropriate, collected otherwise by way of withholding, could apply to such interest under Japanese tax law.

(4) If an individualnon-resident of Japan or anon-Japanese corporation (regardless of whether it is a specially-related person of the issuer) is subject to Japanese withholding tax with respect to interest on the notes under Japanese tax law, a reduced rate of withholding tax or exemption from such withholding tax may be available under the relevant income tax treaty between Japan and the country of tax residence of such individualnon-resident of Japan ornon-Japanese corporation. As of the date of this prospectus supplement, Japan has income tax treaties, conventions or agreements whereby the above-mentioned withholding tax rate is reduced, generally to 10% with, inter alia, Australia, Austria, Belgium, Canada, Denmark, Finland, France, Hong Kong, Ireland, Italy, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Switzerland and the United States. Under the tax treaties between Japan and the United Kingdom, Sweden or Germany, interest paid to qualified United Kingdom, Swedish or German residents is generally exempt from Japanese withholding tax. Japan has also signed amendments to existing tax treaties with the United States, Austria and Denmark generally exempting interest from Japanese withholding tax; however, these amendments have not yet entered into force. Under the current income tax treaty between Japan and the United States, certain limited categories of qualified United States residents receiving interest on the notes may, subject to compliance with certain procedural requirements under Japanese law, be fully exempt from Japanese withholding tax on payments of interest on the notes. Under the income tax treaties with France, Australia, the Netherlands and Switzerland, similar exemptions to those provided in the current income tax treaty between Japan and the United States will be available (provided that no exemption will apply to pension funds in the case of Australia). In order to enjoy such reduced rate of, or exemption from, Japanese withholding tax under any applicable income tax treaty, individualnon-residents of Japan ornon-Japanese corporations which are entitled, under any applicable income tax treaty, to a reduced rate of, or exemption from, Japanese withholding tax on payment of interest by the issuer of the notes are required to submit an Application Form for Income Tax Convention regarding Relief from Japanese Income Tax and Special Income Tax for Reconstruction on Interest (as well as any other required forms and documents) in advance through the issuer of the notes to the relevant tax authority before payment of interest.

(5) Under the Law, if an individualnon-resident of Japan or anon-Japanese corporation that is a beneficial owner of the notes becomes a specially-related person of the issuer, or an individualnon-resident of Japan or anon-Japanese corporation that is a specially-related person of the issuer becomes a beneficial owner of the notes, and, if such notes are held through a Participant, then such individualnon-resident of Japan ornon-Japanese corporation should notify the Participant of such change in status by the immediately following interest payment date of the notes. As described in paragraph 1.1(3) above, as the status of such individualnon-resident of Japan ornon-Japanese corporation as a specially-related person of the issuer for Japanese withholding tax purposes is determined based on the status as of the beginning of the fiscal year of the issuer in which the relevant interest payment date falls, such individualnon-resident of Japan ornon-Japanese corporation should, by such notification, identify and advise the Participant of the specific interest payment date on which Japanese withholding tax starts to apply with respect to such individualnon-resident of Japan ornon-Japanese corporation as being a specially-related person of the issuer.

1.2. Redemption Gain

(1) If the recipient of the Redemption Gain is an individualnon-resident of Japan or anon-Japanese corporation having no permanent establishment within Japan or having a permanent establishment within Japan but the receipt of such Redemption Gain is not attributable to the business of such individualnon-resident of Japan ornon-Japanese corporation carried on within Japan through such permanent establishment, no income tax or corporate tax is payable by way of withholding or otherwise with respect to such Redemption Gain.

(2) If the recipient of the Redemption Gain is an individualnon-resident of Japan or anon-Japanese corporation having a permanent establishment within Japan and the receipt of such Redemption Gain is

S-37

attributable to the business of such individualnon-resident of Japan ornon-Japanese corporation carried on within Japan through such permanent establishment, such Redemption Gain will not be subject to any withholding tax but will be subject to regular income tax or corporate tax, as appropriate.

(3) Notwithstanding paragraphs 1.2(1) and (2), if an individualnon-resident of Japan or anon-Japanese corporation mentioned above is a specially-related person of the issuer as of the beginning of the fiscal year of the issuer of the notes in which such individualnon-resident of Japan ornon-Japanese corporation acquired such notes, the Redemption Gain will not be subject to withholding tax but will be subject to regular income tax or corporate tax, as appropriate, under Japanese tax law, regardless of whether such individualnon-resident of Japan ornon-Japanese corporation has a permanent establishment within Japan; provided that an exemption may be available under the relevant income tax treaty.

2. Resident Investors

If the recipient of interest on the notes is an individual resident of Japan or a Japanese corporation for Japanese tax purposes, as described below, regardless of whether such recipient is a specially-related person of the issuer, in addition to any applicable local tax, income tax will be withheld at the rate of 15.315% of the amount of such interest, if such interest is paid to an individual resident of Japan or a Japanese corporation (except for (i) a Designated Financial Institution which complies with the requirement for tax exemption under Article 6, Paragraph (9) of the Special Taxation Measures Act, or (ii) a Public Corporation, etc., as defined below, or a Specified Financial Institution, as defined below, to which such interest is paid through the Japanese Custodian, as defined below, in compliance with the requirement for tax exemption under Article3-3, Paragraph (6) of the Special Taxation Measures Act.) In addition to the withholding tax consequences upon resident investors as explained in this section 2, resident investors should consult their own tax advisors regarding income tax or corporate tax consequences other than by way of withholding, bearing in mind, especially for individual residents of Japan, the change to the taxation regime of bonds which took effect on January 1, 2016.

2.1. Interest

(1) If an individual resident of Japan or a Japanese corporation (other than a Specified Financial Institution or a Public Corporation etc. who complies with the requirement as referred to in paragraph 2.1(2)) receives payments of interest on the notes through certain Japanese payment handling agents, each a Japanese Payment Handling Agent, income tax at the rate of 15.315% of the amount of such interest will be withheld by the Japanese Payment Handling Agent rather than by the issuer of the notes. As the issuer of the notes is not in a position to know in advance the recipient’s status, the recipient of interest falling within this category should inform the issuer of the notes through a paying agent of its status in a timely manner. Failure to so inform may result in double withholding.

(2) If the recipient of interest on the notes is a Japanese public corporation or a Japanese public-interest corporation designated by the relevant law, or a Public Corporation etc., or a Japanese bank, a Japanese insurance company, a Japanese financial instruments business operator or other Japanese financial institution falling under certain categories prescribed by the relevant Cabinet Order under Article3-3, Paragraph (6) of the Special Taxation Measures Act, each, a Specified Financial Institution, that keeps its notes deposited with, and receives the interest through, a Japanese Payment Handling Agent with custody of the notes, or the Japanese Custodian, and such recipient submits through such Japanese Custodian to the competent tax authority the report prescribed by the Law, no withholding tax is levied on such interest. However, since the issuer of the notes is not in a position to know in advance the recipient’s such tax exemption status, the recipient of interest falling within this category should inform the issuer of the notes through a paying agent of its status in a timely manner. Failure to so notify the issuer of the notes may result in the withholding by the issuer of the notes of a 15.315% income tax.

(3) If an individual resident of Japan or a Japanese corporation (except for a Designated Financial Institution which complies with the requirements described in paragraph 2.1(4)) receives interest on the notes not through a

S-38

Japanese Payment Handling Agent, income tax at the rate of 15.315% of the amount of such interest will be withheld by the issuer of the notes.

(4) If a Japanese bank, Japanese insurance company, Japanese financial instruments business operator or other Japanese financial institution falling under certain categories prescribed by the Cabinet Order under Article 6, Paragraph (9) of the Special Taxation Measures Act, each, a Designated Financial Institution, receives interest on the notes not through a Japanese Payment Handling Agent and the requirements concerning the Interest Recipient Information and the Interest Recipient Confirmation or the Written Application for Tax Exemption as referred to in paragraph 1.1(1) above are complied with, no withholding tax will be imposed.

2.2. Redemption Gain

If the recipient of the Redemption Gain is an individual resident of Japan or a Japanese corporation, such Redemption Gain will not be subject to any withholding tax.

3. Special Additional Tax for Reconstruction from the Earthquake

Due to the imposition of a special additional withholding tax of 0.315% (or 2.1% of 15%) to secure funds for reconstruction from the earthquake of March 11, 2011, the withholding tax rate has been effectively increased to 15.315% during the period beginning on January 1, 2013 and ending on December 31, 2037. On or after January 1, 2038, all references to the tax rate of 15.315% in the foregoing descriptions will read 15%. There is also certain special additional tax imposed upon regular income tax due other than by way of withholding for individualnon-residents of Japan, as referred to in the foregoing descriptions, for the period mentioned above.

Capital Gains, Stamp Tax and Other Similar Taxes, Inheritance and Gift Taxes

Gains derived from the sale of notes outside Japan by an individualnon-resident of Japan or anon-Japanese corporation having no permanent establishment within Japan are, in general, not subject to Japanese income tax or corporate tax.

No stamp, issue, registration or similar taxes or duties will, under current Japanese law, be payable in Japan by noteholders in connection with the issue of the notes, nor will such taxes be payable by noteholders in connection with their transfer if such transfer takes place outside Japan.

Japanese inheritance tax or gift tax at progressive rates may be payable by an individual, wherever resident, who has acquired notes from another individual as legatee, heir or donee.

U.S. Federal Income Tax Considerations

The following is a description of material U.S. federal income tax consequences of the ownership and disposition of the notes by the U.S. Holders described below, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a particular person’s decision to acquire notes. Except as provided in “—Possible FATCA Withholding After 2018” below, this discussion applies to you only if you are a U.S. Holder who purchases notes of any series pursuant to this offering at the “issue price,” which is the first price at which a substantial amount of the notes of that series is sold to the public (not including bond houses, brokers or similar persons acting in the capacity of underwriters, placement agents or wholesalers), and who holds the notes as capital assets for U.S. federal income tax purposes. This discussion does not describe all of the U.S. federal income tax consequences that may be relevant to you in light of your particular circumstances, including the possible effect of the special tax accrual rules under Section 451 (b) of the U.S. Internal Revenue Code of 1986, as amended, or the Code, alternative minimum tax and Medicare contribution tax consequences and differing tax consequences that may be applicable to you if you are, for instance:

• a financial institution;

• an insurance company;

S-39

• a regulated investment company;

• a dealer or trader in securities that uses amark-to-market method of tax accounting;

• holding notes as part of a “straddle” or integrated transaction;

• a person whose functional currency is not the U.S. dollar;

• holding notes in connection with a trade or business conducted outside the United States;

• a partnership (or any other entity treated as a partnership) for U.S. federal income tax purposes; or

• atax-exempt entity.

If you are a partnership (or any other entity treated as a partnership) for U.S. federal income tax purposes, the U.S. federal income tax treatment of your partners will generally depend on the status of the partners and your activities. If you are a partnership owning notes or a partner in such partnership, you should consult your tax adviser as to your particular U.S. federal income tax consequences of owning and disposing of the notes.

This summary is based on the Code, administrative pronouncements, judicial decisions and Treasury regulations, and the income tax treaty between the United States and Japan, or the Treaty, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein, potentially with retroactive effect. This summary does not address any state, local ornon-U.S. tax considerations, or any U.S. federal tax consequences (including estate or gift taxes) other than U.S. federal income tax consequences.

If you are considering the purchase of notes, you should consult your tax adviser with regard to the application of the U.S. federal tax laws to your particular situation, as well as any tax consequences arising under the laws of any state, local ornon-U.S. taxing jurisdiction.

You are a U.S. Holder if for U.S. federal income tax purposes you are a beneficial owner of a note and are:

• a citizen or individual resident of the United States;

• a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States, any state therein or the District of Columbia; or

• an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

Interest

It is expected, and therefore this discussion assumes, that the notes will be issued without original issue discount for U.S. federal income tax purposes. Interest paid on a note will be taxable to you as ordinary income at the time it accrues or is received, in accordance with your method of accounting for U.S. federal income tax purposes. The amount of interest taxable as ordinary income will include amounts, if any, withheld in respect of Japanese taxes and any additional amounts paid with respect thereto as described under “Description of the Debt Securities—Taxation and Additional Amounts” in the accompanying prospectus. See “—Japanese Taxation—The Notes—Interest Payments on Notes and Redemption Gain—1.Non-resident Investors” for a discussion of the requirements for obtaining an exemption from Japanese withholding tax.

Interest will constitute foreign-source income for U.S. federal income tax purposes, and will constitute either “passive category income” or “general category income” for foreign tax credit purposes. Subject to applicable limitations, some of which vary depending upon your particular circumstances, Japanese income taxes withheld from interest payments on a note (at a rate not exceeding any applicable rate under the Treaty) may be creditable against your U.S. federal income tax liability. However, any Japanese withholding taxes on interest payments generally will not be creditable to the extent that the Japanese tax could have been eliminated by timely providing the Interest Recipient Information or the Written Application for Tax Exemption described in “—Japanese Taxation” above. The rules governing foreign tax credits are complex, and you should consult your

S-40

tax adviser regarding the availability of foreign tax credits in your particular circumstances. Instead of claiming a credit, subject to applicable limitations, you may elect to deduct foreign taxes (if any) in computing your taxable income. An election to deduct foreign taxes instead of claiming foreign tax credits must apply to all foreign taxes paid or accrued in the taxable year.

Sale or Other Taxable Disposition of the Notes

Upon the sale or other taxable disposition of a note, you will recognize taxable gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and your tax basis in the note. For these purposes, the amount realized does not include any amount attributable to accrued interest, which is treated as described under “—Interest” above. Your tax basis in a note will generally equal the amount you paid for such note.

Gain or loss realized on the sale or other taxable disposition of a note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of the sale or other taxable disposition the note has been held for more than one year. Long-term capital gains recognized bynon-corporate taxpayers are eligible to be taxed at rates lower than those applicable to ordinary income. The deductibility of capital losses is subject to limitations. Gain or loss generally will be U.S. source for purposes of computing your foreign tax credit limitation.

Backup Withholding and Information Reporting

Information returns may be required to be filed with the IRS in connection with payments on the notes and proceeds received from a sale or other disposition of the notes unless you are an exempt recipient. You may also be subject to backup withholding on these payments in respect of your notes unless you provide your taxpayer identification number and otherwise comply with applicable requirements of the backup withholding rules or, if required, you provide proof of an applicable exemption. Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against your U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Certain U.S. Holders who are individuals (or certain specified entities) may be required to report information relating to the notes ornon-U.S. accounts through which they may be held. You should consult your tax adviser regarding your reporting obligations with respect to the notes.

Possible FATCA Withholding After 2018

Provisions of U.S. tax law commonly referred to as “FATCA” impose a 30% withholding tax on certain U.S. source payments made to a foreign financial institution (such as ourselves, certain of our subsidiaries or a financial intermediary through which an investor may hold notes), unless the financial institution is a PFFI, or otherwise exempt from FATCA. A PFFI is a foreign financial institution that has entered into an agreement with the U.S. Treasury Department pursuant to which it agrees to perform specified due diligence, reporting and withholding functions. Specifically, under its PFFI agreement, a PFFI is required to obtain and report to the IRS certain information with respect to financial accounts held by U.S. persons or U.S.-owned foreign entities and may be required to withhold 30% from “foreign passthru payments” (which term is not yet defined) that it makes to foreign financial institutions that are not PFFIs or otherwise exempt from FATCA and certain other persons who fail to provide requested information, if such payments are made on or after the later of January 1, 2019 and the date of publication of final Treasury regulations defining the term “foreign passthru payments.” No such withholding would apply to any payments made onnon-U.S. debt obligations (such as the notes) that are issued before (and not materially modified after) the date that is six months after the date on which final regulations defining the term “foreign passthru payments” are published. The United States and Japan have entered into an intergovernmental agreement to facilitate the implementation of FATCA pursuant to which Japanese financial institutions (such as ourselves and certain of our subsidiaries) are directed by the Japanese authorities to register

S-41

with the IRS and fulfill obligations consistent with those required under a PFFI agreement. We have registered with the IRS as a PFFI. The United States has also entered into intergovernmental agreements with other jurisdictions. These intergovernmental agreements (including the intergovernmental agreement with Japan) do not address how the United States and the relevant jurisdictions (including Japan) will address “foreign passthru payments” or whether withholding on such payments will be required by financial institutions that are subject to an intergovernmental agreement.

In the event that any amount of withholding is required from a payment on a note under FATCA or any intergovernmental agreement entered into with respect thereto, or any law, regulation or guidance implementing FATCA or such intergovernmental agreement, no additional amounts will be payable by us and withheld amounts will be treated as paid for all purposes under the notes.

S-42

BENEFIT PLAN INVESTOR CONSIDERATIONS

A fiduciary of a pension, profit-sharing or other employee benefit plan subject to Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended, or ERISA, including entities such as collective investment funds, partnerships and separate accounts whose underlying assets include the assets of such plans (collectively, “ERISA Plans”) should consider the fiduciary standards of ERISA in the context of the ERISA Plan’s particular circumstances before authorizing an investment in the notes. Among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA and would be consistent with the documents and instruments governing the ERISA Plan.

Section 406 of ERISA and/or Section 4975 of the Code prohibit ERISA Plans, as well as plans (including individual retirement accounts and Keogh plans) subject to Section 4975 of the Code (together with ERISA Plans, “Plans”), from engaging in certain transactions involving the “plan assets” with persons who are “parties in interest” under ERISA or “disqualified persons” under Section 4975 of the Code (in either case, “Parties in Interest”) with respect to such Plans. As a result of our business, we, the underwriters, the trustee or our or their affiliates (collectively, the “Sellers”) may be Parties in Interest with respect to many Plans. Where any of the Sellers is a Party in Interest with respect to a Plan, the purchase and holding of the notes (including any interest in a note) by or on behalf of the Plan could be a prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless exemptive relief were available under an applicable exemption (as described below).

Certain prohibited transaction class exemptions, or PTCEs, issued by the U.S. Department of Labor may provide exemptive relief for direct or indirect prohibited transactions resulting from the purchase or holding of the notes. Those class exemptions include PTCE96-23 (for certain transactions determined byin-house asset managers), PTCE95-60 (for certain transactions involving insurance company general accounts), PTCE91-38 (for certain transactions involving bank collective investment funds), PTCE90-1 (for certain transactions involving insurance company separate accounts) and PTCE84-14 (for certain transactions determined by independent qualified asset managers). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code may provide a limited exemption for the purchase and sale of the notes and related lending transactions, provided that neither we, the underwriters nor any of our or their affiliates have or exercise any discretionary authority or control or render any investment advice with respect to the assets of the Plan involved in the transaction and provided further that the Plan pays no more, and receives no less, than adequate consideration in connection with the transaction (theso-called “service provider exemption”). Each of the above noted exemptions contains conditions and limitations on its application. Fiduciaries of Plans considering acquiring and/or holding the notes in reliance on these or any other exemption should carefully review the exemption to ensure it is applicable. There can be no assurance that any of these or any other statutory or class exemptions will be available with respect to any particular transaction involving the notes.

Certain governmental plans (as defined in Section 3(32) of ERISA), church plans (as defined in Section 3(33) of ERISA) andnon-U.S. plans (as described in Section 4(b)(4) of ERISA), orNon-ERISA Arrangements, are not subject to these “prohibited transaction” rules of ERISA or Section 4975 of the Code, but may be subject to similar rules under other applicable laws or regulations, or Similar Laws.

Each purchaser and subsequent transferee of a note (including any interest in a note) pursuant to this prospectus supplement, including any fiduciary purchasing a note (or interest therein) on behalf of a Plan or aNon-ERISA Arrangement, will be deemed to have represented, in its corporate and its fiduciary capacity, that (a) either (i) it is not acquiring or holding the notes with the assets of a Plan orNon-ERISA Arrangement or (ii) its acquisition and holding of the notes will not constitute or result in anon-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a violation under any applicable Similar Law and (b) if it is a Plan, a fiduciary independent of the Sellers, or the Fiduciary, acting on the Plan’s behalf is and at all times will be responsible for the decision to invest in and hold the notes as contemplated hereby and that such Fiduciary (i) is either a U.S. bank, a U.S. insurance carrier, a U.S. registered investment adviser, a U.S. registered

S-43

broker-dealer or an independent fiduciary with at least $50 million of assets under management or control, in each case under the requirements specified in the U.S. Code of Federal Regulations, 29 C.F.R Section 2510.3-21 (c)(1)(i), as amended from time to time, or the Fiduciary Rule, (ii) in the case of a Plan that is an individual retirement account, or an IRA, is not the IRA owner, beneficiary of the IRA or relative of the IRA owner or beneficiary, (iii) is capable of evaluating investment risks independently, both in general and with regard to the prospective investment in the notes, (iv) is a fiduciary under ERISA or the Code, or both, with respect to the decision to acquire and hold the notes, (v) has exercised independent judgment in evaluating whether to invest the assets of the Plan in the notes, (vi) understands and has been fairly informed of the existence and the nature of the financial interests of the Sellers in connection with the Plan’s acquisition of the notes, (vii) understands that the Sellers are not undertaking to provide impartial investment advice, or to give advice in a fiduciary capacity to the Plan, in connection with the Plan’s acquisition of the notes and (viii) confirms that no fee or other compensation will be paid directly to any of the Sellers by the Plan, or any fiduciary, participant or beneficiary of the Plan, for the provision of investment advice (as opposed to other services) in connection with the Plan’s acquisition of the notes;provided, that the above representations in clause (b) shall no longer be effective if the Fiduciary Rule is revoked, repealed or no longer effective.

Each purchaser and holder of the notes has exclusive responsibility for ensuring that its purchase, holding and subsequent disposition of the notes does not violate the fiduciary or prohibited transaction rules of ERISA, the Code or any applicable Similar Laws. The sale of any notes to any Plan orNon-ERISA Arrangement is in no respect a representation by us, the underwriters or any of our or their affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by Plans orNon-ERISA Arrangements generally or any particular Plan orNon-ERISA Arrangement, or that such an investment is appropriate for Plans orNon-ERISA Arrangements generally or any particular Plan orNon-ERISA Arrangement.

Neither this discussion nor anything in this prospectus supplement is or is intended to be investment advice directed at any potential purchaser that is a Plan orNon-ERISA Arrangement, or at such purchasers and holders generally, and such purchasers and holders should consult and rely on their counsel and advisors as to whether an investment in the notes is suitable and consistent with ERISA, the Code and any Similar Laws, as applicable.

The underwriters are entitled to be released and discharged from their obligations under, and to terminate, the underwriting agreement in certain circumstances prior to paying us for the notes. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of thenon-defaulting underwriters may be increased. The underwriters are offering the notes subject to their acceptance of the notes from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the notes are subject to approval of certain legal matters by their counsel and to certain other conditions.

The underwriting agreement provides that we will indemnify the underwriters and their affiliates against specified liabilities, including liabilities under the Securities Act, in connection with the offer and sale of the notes, and will contribute to payments the underwriters and their affiliates may be required to make in respect of those liabilities.

Commissions

The underwriters have advised us that they propose initially to offer each series of the notes at the public offering prices listed on the cover page of this prospectus supplement. After the initial offering, the public offering prices, concessions or any other term of the offering may be changed. The underwriters have agreed to purchase each series of the notes from us at the public offering price, and we have agreed to pay the underwriters a fee of 0.35% of the principal amount of the 5-year notes, a fee of 0.45% of the principal amount of the 10-year notes and a fee of 0.35% of the principal amount of the floating rate notes.

S-45

Securities and Exchange Commission registration fee	$	249,000
Printing expenses		27,648
Legal fees and expenses		406,109
Accounting fees and expenses		117,632

Price Stabilization and Short Positions

In connection with the offering, SMBC Nikko Securities America, Inc., or the Stabilization Manager, and/or any person acting on behalf thereof, may purchase and sell the notes in the open market and engage in other transactions, subject to applicable laws and regulations. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the Stabilization Manager and/or any person acting on behalf thereof of a greater principal amount of the notes than they are required to purchase from us in the offering. Stabilizing transactions consist of bids or purchases by the Stabilization Manager and/or any person acting on behalf thereof for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress. These transactions may also include stabilizing transactions by the Stabilization Manager and/or any person acting on behalf thereof for the accounts of the underwriters.

In addition, the Stabilization Manager and/or any person acting on behalf thereof may impose a penalty bid. A penalty bid is an arrangement that permits the Stabilization Manager and/or any person acting on behalf thereof to reclaim a selling concession from a syndicate member in connection with the offering when the notes originally sold by the syndicate member are purchased in syndicate covering transactions.

These activities may stabilize, maintain or otherwise affect the market prices of the notes. As a result, the price of the notes may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued at any time.

One or more of the underwriters may not be U.S.-registered broker-dealers. All sales of securities in the United States will be made by or through U.S.-registered broker-dealers, which may include affiliates of one or more of the underwriters.

No Sale of Similar Securities

We have agreed, during the period from the date of this document through and continuing until the closing of the offering, without the prior written consent of the underwriters, not to, directly or indirectly, issue, sell, offer or contract to sell, grant any option for the sale of, or otherwise transfer or dispose of, in any market outside Japan, any U.S. dollar-denominated senior debt securities of SMFG.

New Issues of the Notes

The notes are new issues of securities with no established trading market. We have made an application to the Luxembourg Stock Exchange to list the notes on the official list of the Luxembourg Stock Exchange and for such notes to be admitted to trading on the Luxembourg Stock Exchange’s Euro MTF Market. The underwriters have advised us that they presently intend to make a market in the notes after completion of this offering. SMBC

S-46

Nikko Securities America, Inc. and our other broker-dealer affiliates may use this prospectus supplement and the accompanying prospectus in connection with these activities. Such market making activity will be subject to the limits imposed by applicable laws. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. Broker-dealers subject to prospectus delivery requirements may be unable to engage in market-making transactions during certain periods of the year. A liquid or active public trading market for the notes may not develop. If an active trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected. If the notes are traded, they may trade at a discount from their initial public offering price, depending on the market for similar securities, our performance and other factors. See “Risk Factors—Risks Related to the Notes—There is no prior market for the notes and, if a market develops, it may not be liquid.”

Selling Restrictions

Canada

The notes may be sold only in any province of Canada to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Under Canadian securities law, National Instrument33-105Underwriting Conflicts(NI33-105) provides disclosure requirements with respect to potential conflicts of interest between an issuer and underwriters, dealers or placement agents, as the case may be. To the extent any conflict of interest between us and any of the underwriters (or any other placement agent acting in connection with this offering) may exist in respect of this offering, the applicable parties to this offering are relying on the exemption from these disclosure requirements provided to them by section 3A.3 of NI33-105 (Exemption based on U.S. disclosure).

Upon receipt of this document, each Canadian purchaser hereby confirms that it has expressly requested that all documents evidencing or relating in any way to the sale of the securities described herein (including for greater certainty any purchase confirmation or any notice) be drawn up in the English language only.Par la réception de ce document, chaque acheteur canadien confirme par les présentes qu’il a expressément exigé que tous les documents faisant foi ou se rapportant de quelque manière que ce soit à la vente des valeurs mobilières décrites aux présentes (incluant, pour plus de certitude, toute confirmation d’achat ou tout avis) soient rédigés en anglais seulement.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, corporate trust, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking and commercial banking services for us or our subsidiaries and affiliates, for which they received or will receive customary fees and expenses.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities), financial instruments (including bank loans), currencies and commodities for their own account and for the accounts of their customers, and such investment and securities activities may involve securities, instruments or assets of ours or related to our business. If any of the underwriters and their respective affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their respective affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their respective affiliates may also make investment recommendations and may publish or express independent research views in respect of such securities or instruments or in respect of assets, currencies or commodities that may be related to our business, and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities, instruments, currencies or commodities.

We have certain longstanding business arrangements with Goldman Sachs, including an arrangement for us to provide credit loss protection. See “Item 4.B. Business Overview—Description of Operations and Principal Activities—Other Major Group Companies and Alliances—Credit Loss Protection Agreement with Goldman Sachs” of our most recent annual report on Form20-F for more details.

We have a strategic business alliance with Citigroup Inc., including an arrangement for Citigroup Inc. to provide us with global corporate and investment banking network access.

Conflicts of Interest

SMBC Nikko Securities America, Inc. is an affiliate of ours and, as a result, has a “conflict of interest” under Rule 5121. Consequently, this offering is being conducted in compliance with the provisions of Rule 5121. Because this offering is of notes that are rated investment grade, pursuant to Rule 5121, the appointment of a “qualified independent underwriter” is not necessary. SMBC Nikko Securities America, Inc. will not confirm sales to accounts over which it exercises discretionary authority without the prior specific written approval of its customer.

Settlement

We expect delivery of the notes will be made against payment therefor on or about July 19, 2018, which is the fifth New York business day following the date of pricing of the notes. Under Rule15c6-1 of the U.S. Securities Exchange Act of 1934, as amended, or the Exchange Act, trades in the secondary market generally are

S-50

required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing of the notes or the next two succeeding business days will be required, by virtue of the fact that the notes initially will settle five New York business days after pricing of the notes, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisers.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the SEC utilizing a “shelf” registration process. Under this shelf registration process, we may, from time to time, sell the debt securities described in this prospectus in one or more offerings.

This prospectus provides you with a general description of the debt securities that we may offer. Each time we sell debt securities, we will provide a prospectus supplement that will contain specific information about the terms of the debt securities and the offering. The prospectus supplement may also add, update or change information contained in this prospectus. The prospectus supplement will supersede this prospectus to the extent it contains information that is different from, or conflicts with, the information contained in this prospectus. You should read this prospectus, any applicable prospectus supplement and any related free writing prospectus that we authorize to be delivered to you together with additional information described under the heading “Where You Can Find More Information” beginning on page 27 of this prospectus before purchasing any of our securities.

We have not authorized any other person to provide you with any information other than that contained or incorporated by reference in this prospectus or in any applicable prospectus supplement or free writing prospectus prepared by or on behalf of us or to which we have referred you. “Incorporated by reference” means that we can disclose important information to you by referring you to another document filed separately with the SEC. We are not responsible for, and can provide no assurance as to the accuracy of, any other information that any other person may give you. We are not making, nor will we make, an offer to sell securities in any jurisdiction where the offer or sale is not permitted. You should not assume that the information appearing in this prospectus or in any applicable prospectus supplement or free writing prospectus prepared by or on behalf of us or to which we have referred you, including any information incorporated by reference herein or therein, is accurate as of any date other than their respective dates. Our business, financial condition, results of operations and prospects may have changed since those respective dates.

In this prospectus and any prospectus supplement, where information is presented in millions of yen or thousands or millions of dollars, amounts of less than one thousand or one million, as the case may be, have been truncated. Where information is presented in billions or trillions of yen or billions of dollars, amounts of less than one billion or one trillion, as the case may be, have been rounded. Accordingly, the total of each column of figures may not be equal to the total of the individual items. All percentages have been rounded to the nearest percent, one-tenth of one percent or one-hundredth of one percent, as the case may be.

Unless otherwise specified or required by the context: references to “days” are to calendar days; references to “years” are to calendar years and to “fiscal years” are to our fiscal years ending on March 31; references to “$,” “dollars” and “U.S. dollars” are to United States dollars and references to “yen” and “¥” are to Japanese yen. Unless otherwise specified, when converting currencies into yen we use the Sumitomo Mitsui Banking Corporation’s median exchange rates for buying and selling spot dollars, or other currencies, by telegraphic transfer against yen as determined at the end of the relevant fiscal period. Unless the context otherwise requires, “SMFG,” the “issuer,” “we,” “us,” “our,” and similar terms refer to Sumitomo Mitsui Financial Group, Inc. as well as to its subsidiaries. References to the “Group” are to us and our subsidiaries and affiliates taken as a whole. “SMBC” and the “Bank” refer to our main subsidiary, Sumitomo Mitsui Banking Corporation or to Sumitomo Mitsui Banking Corporation and its subsidiaries, taken as a whole, as the context requires. References to “non-consolidated” information are to the financial information solely of SMBC.

Our primary financial statements for SEC reporting purposes are prepared on an annual and semi-annual basis in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, or IFRS, while our financial statements for reporting in our jurisdiction of incorporation and Japanese bank regulatory purposes are prepared in accordance with accounting principles generally accepted in Japan, or Japanese GAAP.

IFRS and Japanese GAAP differ in certain respects from each other and from generally accepted accounting principles in the United States, or U.S. GAAP, and in other countries. For a description of certain differences between IFRS and Japanese GAAP, see “Item 5.A Operating Results—Reconciliation with Japanese GAAP” in our most recent annual report on Form 20-F filed with the SEC. You should consult your own professional advisers for a more complete understanding of the differences between IFRS, Japanese GAAP, U.S. GAAP and the generally accepted accounting principles of other countries and how those differences might affect the financial information contained or incorporated by reference in this prospectus or the accompanying prospectus.

Financial information for us contained or incorporated by reference herein is presented in accordance with IFRS or Japanese GAAP, as specified herein or in the relevant document being incorporated by reference. Financial information for SMBC contained or incorporated by reference herein is presented in accordance with Japanese GAAP.

In this prospectus all of our financial information is presented on a consolidated basis, unless we state otherwise.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the financial statements and other documents incorporated by reference in this prospectus contain forward-looking statements, including statements concerning our industry, our operations, our anticipated financial performance and financial condition, and our business plans and growth strategy and product development efforts. These statements constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the U.S. Securities Exchange Act of 1934, as amended, or Exchange Act. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “probability,” “risk,” “project,” “should,” “seek,” “target,” “will” and similar expressions, among others, are intended to identify forward-looking statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of their dates. These forward-looking statements are based on estimates and assumptions by our management that, although we believe to be reasonable, are inherently uncertain and subject to a number of risks and uncertainties.

Forward-looking statements are not guarantees of future performance and involve risks and uncertainties, and actual results may differ from those in the forward-looking statements as a result of various factors, and the differences may be material. Potential risks and uncertainties include, without limitation, the following:

• deterioration of Japanese and global economic conditions and financial markets;

• constraints on our operations due to capital adequacy requirements;

• declines in the value of our securities portfolio;

• changes in the level or volatility of market rates or prices;

• incurrence of significant credit-related costs;

• a significant downgrade of our credit ratings;

• our ability to successfully implement our business strategy through our subsidiaries, affiliates and alliance partners;

• exposure to new risks as we expand the scope of our business;

• the industry specific risks of the consumer finance industry;

• the recoverability of deferred tax assets;

• litigation and regulatory proceedings;

2

• insufficient liquidity;

• problems of other financial institutions;

• adverse regulatory developments or changes in government policies; and

• other risk factors set forth in our most recent annual report on Form 20-F or in an applicable prospectus supplement.

Our actual results or performance could differ materially from those expressed in, or implied by, any forward-looking statements relating to those matters. Accordingly, no assurances can be given that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do so, what impact they will have on our results of operations, cash flows or financial condition. Except as required by law, we are under no obligation, and expressly disclaim any obligation, to update, alter or otherwise revise any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future events or otherwise.

RISK FACTORS

Before making a decision to invest in our debt securities, you should carefully consider the risks described under “Risk Factors” in our then most recent annual report on Form 20-F, in any updates to those risk factors in our reports on Form 6-K incorporated herein and in any applicable prospectus supplement, together with all of the other information appearing or incorporated by reference in this prospectus and any applicable prospectus supplement, in light of your particular investment objectives and financial circumstances.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our ratio of earnings to fixed charges, presented in accordance with IFRS, for each of the periods indicated. You should read this table in conjunction with the consolidated financial statements and notes incorporated by reference in this prospectus.

	Fiscal year ended March 31,										Six months ended September 30, 2015
	2011		2012		2013		2014		2015

Including interest on deposits		3.05		3.08		2.92		3.87		3.33		3.62

In calculating the ratio of earnings to fixed charges, we used the following definitions:

The term “fixed charges” means the sum of the following: (a) interest expensed and capitalized, (b) amortized premiums, discounts and capitalized expenses related to indebtedness, (c) an estimate of the interest within rental expense and (d) preference security dividend requirements of consolidated subsidiaries.

The term “earnings” is the amount resulting from adding and subtracting the following items. Add the following: (a) pre-tax income from continuing operations before adjustment for income or loss from equity investees, (b) fixed charges, (c) amortization of capitalized interest, (d) distributed income of equity investees and (e) our share of pre-tax losses of equity investees for which charges arising from guarantees are included in fixed charges. From the total of the added items, subtract the following: (a) interest capitalized, (b) preference security dividend requirements of consolidated subsidiaries and (c) the non-controlling interest in pre-tax income of subsidiaries that have not incurred fixed charges. Equity investees are investments that we account for using the equity method of accounting.

DESCRIPTION OF THE DEBT SECURITIES

The following is a summary of certain general terms and provisions of the senior and subordinated debt securities, collectively the “debt securities,” that we may offer under this prospectus. The specific terms and provisions of a particular series of debt securities to be offered, and the extent, if any, to which the general terms and provisions summarized below apply to such securities, will be described in an applicable prospectus supplement or free writing prospectus that we authorize to be delivered in connection with such offering. If there is any inconsistency between the general terms and provisions presented here and those in the applicable prospectus supplement or free writing prospectus, those in the applicable prospectus supplement or free writing prospectus will apply.

Because this section is a summary, it does not describe every aspect of the debt securities. It is qualified in its entirety by the provisions of the senior and subordinated indentures (as described below) and the senior and subordinated debt securities, forms of which have been filed as exhibits to the registration statement of which this prospectus is part. You should refer to those documents for additional information.

When we refer to “the Company,” “we,” “our,” and “us” in this section, we mean Sumitomo Mitsui Financial Group, Inc., excluding, unless the context otherwise requires or as otherwise expressly stated, any existing or future subsidiaries.

General

We may issue senior debt securities from time to time, in one or more series under a senior indenture to be entered into upon the initial issuance of senior debt securities, between us and The Bank of New York Mellon, which we refer to as the senior trustee. We may issue subordinated debt securities, from time to time, in one or more series under a subordinated indenture to be entered into upon the initial issuance of subordinated debt securities between us and The Bank of New York Mellon, which we refer to as the subordinated trustee. Subordinated debt securities may be issued with or without a fixed maturity date. The senior indenture and the subordinated indenture are sometimes referred to in this prospectus collectively as the “indentures” and each, individually, as an “indenture,” and the senior trustee and the subordinated trustee are sometimes referred to in this prospectus as the “trustee.” The terms “senior indenture,” “subordinated indenture” and “indenture” as used herein may, depending on the context, refer to such indenture, as amended or supplemented.

The indentures will provide that we may issue debt securities up to an aggregate principal amount as we may authorize from time to time. Neither of the indentures will limit the amount of debt securities that we may issue thereunder, nor will they contain any limitations on the amount of other indebtedness or other liabilities that we or any of our subsidiaries may incur.

The senior debt securities of each series will constitute our direct, unconditional, unsecured and unsubordinated general obligations and will at all times rankpari passu without any preference among themselves and with all our other unsecured obligations, other than our subordinated obligations and except for statutorily preferred obligations.

The subordinated debt securities of each series will constitute our direct and unsecured obligations and will at all times rankpari passu among themselves without any preference. The nature and extent of the subordinated ranking of, and the other subordination provisions applicable to, a series of subordinated debt securities will be described in the applicable prospectus supplement relating to such series of subordinated debt securities.

Events of Default and Rights of Acceleration

Senior Debt Securities

The senior indenture will provide holders of our senior debt securities with remedies if we fail to perform specific obligations, such as making payments on the senior debt securities, or if we become subject to certain bankruptcy, insolvency or similar proceedings. In many cases, whether an event of default has occurred is determined on a series-by-series basis.

An event of default will be defined under the senior indenture, with respect to any series of senior debt securities issued under that indenture, as the occurrence and continuation of any one or more of the following events:

• Default shall be made for more than 15 days in the payment of principal and premium, if any, and for more than 30 days in the payment of interest in respect of any of the senior debt securities of such series;

• We shall have defaulted in the performance or observance of any covenant, condition or provision contained in the senior debt securities of such series or in the senior indenture in respect of the senior debt securities of such series for a period of 90 days after written notification requesting such default to be remedied by us shall first have been given to us by the trustee or holders of at least 25% in principal amount of the then outstanding senior debt securities of such series;

• Except for the purposes of or pursuant to a consolidation, amalgamation, merger or reconstruction under which the continuing corporation or other person, or the corporation or other person formed as a result thereof, effectively assumes our entire obligations under the indenture in relation to the senior debt securities of such series: (a) a decree or order by any court having jurisdiction shall have been issued adjudging us bankrupt or insolvent, or approving a petition seeking our reorganization or liquidation under bankruptcy, civil rehabilitation, reorganization or insolvency law of Japan, and such decree or order shall have continued undischarged and unstayed for a period of 90 days, or a final and non-appealable order of a court of competent jurisdiction shall have been made for our winding up or dissolution or (b) we shall have initiated or consented to proceedings relating to ourselves under bankruptcy, civil rehabilitation, reorganization or insolvency law of Japan, or an effective resolution shall have been passed by us for our winding up or dissolution; or

9

• Any other event of default provided for in such series of senior debt securities as may be specified in the applicable prospectus supplement.

Under the senior indenture, the senior trustee shall be required to give notice by mail to the holders of the relevant series of the senior debt securities of all defaults known to the senior trustee that have occurred with respect to such series. The senior trustee shall be required to transmit the notice within 90 days of such occurrence of an event of default, or, if later, within 15 days after such event of default is notified in writing to a responsible officer of the senior trustee, unless the defaults have been cured before transmission of such notice.

The senior indenture provides that if any event of default shall occur and be continuing with respect to a series of senior debt securities, unless the principal of all the senior debt securities of such series has already become due and payable, either the senior trustee or the holders of not less than 25% in aggregate principal amount of the senior debt securities of such series then outstanding, by notice in writing to us (and to the senior trustee if given by the holders), may, and the senior trustee at the request of such holders shall (subject to the senior trustee being indemnified and/or secured to its reasonable satisfaction), declare the entire principal of all such outstanding senior debt securities of such series, together with all accrued and unpaid interest, to be due and payable immediately.

Subordinated Debt Securities

Events of default, events of acceleration and other defaults applicable to a series of subordinated debt securities will be described in an applicable prospectus supplement and set forth in the subordinated indenture relating to such series of subordinated debt securities.

Waiver of Default or Acceleration

Prior to the acceleration of the maturity of any of the debt securities, the holders of a majority in aggregate principal amount of the outstanding debt securities of all affected series then outstanding under the indenture relating to such debt securities (voting together as a single class) also have the right to waive any past default, event of default or event of acceleration, as the case may be, and its consequences, except a default in respect of a covenant or a provision of such indenture that cannot be modified or amended without the consent of the holder of each debt security affected thereby.

Further Issuances

The indentures will permit us from time to time and without the consent of the holders of the debt securities of a particular series, to create and issue additional debt securities on the same terms and conditions as the original debt securities of such series, except as to denomination, issue date, issue price and, if applicable, the date from which interest shall accrue and the date on which interest shall be first paid. Any additional debt securities issued in this manner may be consolidated and treated as a single series with the relevant series of debt securities and originally constituting such series for all purposes under the relevant indenture, provided that such additional debt securities that are so consolidated must be fungible for U.S. federal income tax purposes with the outstanding debt securities of the relevant series.

We also may, without the consent of the holders of the outstanding debt securities, issue other series of debt securities in the future under the indentures on terms and conditions different from the debt securities offered hereby.

Taxation and Additional Amounts

We will make all payments of principal and interest in respect of the debt securities without withholding or deduction for or on account of any present or future taxes, duties, assessments or other governmental charges of

10

whatever nature imposed or levied by or on behalf of Japan, or any authority thereof or therein having power to tax, unless such withholding or deduction is required by law. In such event, we shall pay to a holder such additional amounts as will result in the receipt by the holder of such amounts as would have been received by it had no such withholding or deduction been required, except that no such additional amounts shall be payable with respect to any of the debt securities under any of the following circumstances:

• the holder or beneficial owner of the debt securities is an individual non-resident of Japan or a non-Japanese corporation and is liable for such taxes in respect of such debt securities by reason of its having some connection with Japan other than the mere holding of such debt securities or being a person having a special relationship with us as described in Article 6, Paragraph (4) of the Special Taxation Measures Act;

• the holder or beneficial owner of the debt securities would otherwise be exempt from any such withholding or deduction but fails to comply with any applicable requirement to provide interest recipient information or to submit a written application for tax exemption to the relevant paying agent to whom the relevant debt securities are presented (where presentation is required), or whose interest recipient information is not duly communicated through the relevant Participant (as defined below) and the relevant international clearing organization to such paying agent;

• the holder or beneficial owner of the debt securities is for Japanese tax purposes treated as an individual resident of Japan or a Japanese corporation (except for a designated financial institution (as defined below) that complies with the requirement to provide interest recipient information or to submit a written application for tax exemption and an individual resident of Japan or a Japanese corporation that duly notifies (directly or through the relevant Participant or otherwise) the relevant paying agent of its status as not being subject to withholding or deduction by us by reason of receipt by such individual resident of Japan or Japanese corporation of interest on the relevant debt securities through a payment handling agent in Japan appointed by it);

• the debt securities are presented for payment (where presentation is required) more than 30 days after the day on which such payment on the debt securities became due or after the full payment was provided for, whichever occurs later, except to the extent the holder thereof would have been entitled to additional amounts on presenting the same for payment on the last day of such period of 30 days;

• the withholding or deduction is imposed on a payment pursuant to European Council Directive 2003/48/EC or any other directive amending, supplementing or implementing such Directive, or any law implementing such directives;

• the withholding or deduction is imposed on a holder or beneficial owner who could have avoided such withholding or deduction by presenting its debt securities (where presentation is required) to another paying agent maintained by us;

• the holder is a fiduciary or partnership or is not the sole beneficial owner of the payment of the principal of, or any interest on, a debt security, and Japanese law requires the payment to be included for tax purposes in the income of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner, in each case, that would not have been entitled to such additional amounts had it been the holder of such debt security; or

• any combination of the above.

No additional amounts will be payable for or on account of any deduction or withholding imposed pursuant to Sections 1471-1474 of the U.S. Internal Revenue Code and the U.S. Treasury regulations thereunder, or FATCA, any intergovernmental agreement entered into with respect to FATCA, or any law, regulation or other official guidance enacted or published in any jurisdiction implementing, or relating to, FATCA or any intergovernmental agreement.

Where the debt securities are held through a participant of an international clearing organization or a financial intermediary, or a Participant, in order to receive payments free of withholding or deduction by us for or

11

on account of any present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of Japan, or any authority thereof or therein having power to tax, if the relevant beneficial owner is an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of ours) or a Japanese financial institution falling under certain categories prescribed by the Special Taxation Measures Act, or a designated financial institution, each such beneficial owner shall, at the time of entrusting a Participant with the custody of the relevant debt securities, provide certain information prescribed by the Special Taxation Measures Act to enable the Participant to establish that such beneficial owner is exempted from the requirement for withholding or deduction of such taxes, and advise the Participant if the beneficial owner ceases to be so exempted (including the case in which a beneficial owner who is an individual non-resident of Japan or a non-Japanese corporation becomes a specially-related person of ours).

Where the debt securities are not held through a Participant, in order to receive payments free of withholding or deduction by us for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of Japan, or any authority thereof or therein having power to tax, if the relevant beneficial owner is an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of ours) or a designated financial institution falling under certain categories prescribed by the Special Taxation Measures Act, each such beneficial owner shall, prior to each time at which it receives interest, submit to the relevant paying agent a written application for tax exemption (hikazei tekiyo shinkokusho), in a form obtainable from the paying agent stating, among other things, the name and address (and, if applicable, the Japanese individual or corporation ID number) of the beneficial owner, the title of the debt securities, the relevant interest payment date, the amount of interest and the fact that the beneficial owner is qualified to submit the written application for tax exemption, together with documentary evidence regarding its identity and residence.

By subscribing to any debt securities, an investor will be deemed to have represented that it is a beneficial owner who is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individual non-resident of Japan or a non-Japanese corporation that in either case is a person having a special relationship with the issuer of the debt securities as described in Article 6, Paragraph (4) of the Special Taxation Measures Act or (ii) a Japanese financial institution, designated in Article 6, Paragraph (9) of the Special Taxation Measures Act.

We will make any required withholding or deduction and remit the full amount withheld or deducted to the Japanese taxing authority in accordance with applicable law. We will use reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any tax, duty, assessment, fee or other governmental charge so withheld or deducted from the Japanese taxing authority imposing such tax, duty, assessment or other governmental charge and if certified copies are not available we will use reasonable efforts to obtain other evidence, and the trustee will make such certified copies or other evidence available to the holders upon reasonable request to the trustee.

If (i) subsequent to making a payment on the debt securities without withholding or deduction of Japanese taxes we are required to remit to the Japanese taxing authority any amount in respect of Japanese taxes that should have been withheld or deducted from such payment (together with any interest and penalties) due to the failure of the beneficial owner to provide accurate interest recipient information or to otherwise properly claim an exemption from Japanese taxes imposed with respect to such payment, and (ii) such beneficial owner would not have been entitled to receive additional amounts with respect to such payment had Japanese taxes been withheld from the payment when it was made, such beneficial owner (but not any subsequent beneficial owner of the debt securities) shall be required to reimburse us, in Japanese yen, for the amount remitted by us to the Japanese taxing authority.

The obligation to pay additional amounts with respect to any taxes, duties, assessments or other governmental charges shall not apply to any estate, inheritance, gift, sales, transfer, personal property or any similar tax, duty, assessment, fee or other governmental charge or any tax, duty, assessment, fee or other

12

governmental charge which is payable otherwise than by withholding or deduction from payments of principal of or interest on the debt securities; provided that, except as otherwise set forth in the debt securities or in the relevant indenture, we will pay all stamp, court or documentary taxes or any excise or property taxes, charges or similar levies and other duties, if any, which may be imposed by Japan, the United States or any political subdivision or any taxing authority thereof or therein, with respect to the execution and enforcement of the relevant indenture or as a consequence of the initial issuance, execution, delivery or registration of the debt securities.

References to principal or interest in respect of the debt securities shall be deemed to include any additional amounts due which may be payable as set forth in the debt securities and the relevant indenture.

Repurchases

We, or any subsidiary of ours, may at any time but subject to prior confirmation or approval of the FSA (if such confirmation or approval is required under applicable Japanese laws or regulations then in effect) purchase any or all of the debt securities in the open market or otherwise at any price. Subject to applicable law, neither we nor any subsidiary of ours shall have any obligation to offer to purchase any debt securities held by any holder as result of our or its purchase or offer to purchase debt securities held by any other holder in the open market or otherwise. Any debt securities so repurchased by us or any subsidiary of ours and surrendered to the paying agent shall be cancelled.

Consolidation, Merger, Sale or Conveyance

The indentures will provide that we may consolidate with or merge into any other person or sell or dispose of our properties and assets substantially as an entirety, whether as a single transaction or a number of transactions, related or not, to any person; provided that, among other things, such person formed by such consolidation or into which we are merged or such person who acquires our properties and assets substantially as an entirety is a joint stock company (kabushiki kaisha) incorporated and validly existing under the laws of Japan, and expressly assumes our obligations under all series of debt securities issued under the relevant indenture, and further provided that, immediately after giving effect to such transaction, no event of default, in the case of the senior debt securities, and no event of acceleration, in the case of the subordinated debt securities, shall have occurred and be continuing.

Paying Agents

Whenever we appoint a paying agent to make payments required under an indenture and the relevant series of debt securities, such paying agent will hold all sums received by it for the payment of the principal and interest on the securities in trust for the benefit of the holders of the debt securities and will make payments to such holders as provided for in the relevant indenture and the debt securities.

Indemnification of Judgment Currency

We will indemnify each holder of a debt security to the full extent permitted by applicable law against any loss incurred by such holder as a result of any judgment or order being given or made for any amount due under such debt security and such judgment or order being expressed and paid in a judgment currency other than U.S. dollars and as a result of any variation as between the rate of exchange at which the U.S. dollar is converted into the judgment currency for the purpose of such judgment or order and the spot rate of exchange in The City of New York at which the trustee on the day on which final non-appealable judgment is entered is able to purchase U.S. dollars with the amount of the judgment currency actually received by the holder. This indemnification will constitute our separate and independent obligation and will continue notwithstanding any such judgment.

13

Satisfaction and Discharge

We may discharge all of our obligations with respect to any or all series of debt securities, other than as to transfers and exchanges, under each indenture if we shall have:

• paid or caused to be paid the principal of and interest on all of the debt securities of such series outstanding (other than debt securities of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in the indenture) as and when the same shall have become due and payable; or

• delivered to the paying agent for cancellation all of the debt securities of such series theretofore authenticated (other than debt securities of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in the indenture).

Modification and Waiver

Any amendment or modification to the principal terms of the debt securities is subject to the terms of the indenture and to prior confirmation or approval of the FSA, if such confirmation or approval is required under applicable Japanese laws or regulations then in effect.

In addition, in the case of subordinated debt securities, no amendment or modification which is prejudicial to any present or future creditor in respect of any senior indebtedness (as such term is defined with respect to the relevant series of subordinated debt securities) shall be made to the subordination provision contained in the relevant subordinated indenture.

Without Consent of Holders

We and the trustee may enter into supplemental indentures without the consent of the holders of debt securities issued under each indenture to:

• cure ambiguities, defects or inconsistencies, or make or amend other provisions which shall not adversely affect the interests of the holders of the debt securities in any material respect;

• add covenants for the protection of the holders of the debt securities;

• establish the forms or terms of the debt securities of any series;

• evidence and provide for the acceptance of appointment by a successor trustee; or

• evidence the assumption by a successor of the obligations of us under the debt securities and the indenture.

With Consent of Holders

Each of us and the trustee, with the consent of the holders of not less than a majority in aggregate principal amount of each affected series of outstanding debt securities (voting together as a single class), may add any provisions to, or change in any manner or eliminate any of the provisions of, each indenture or modify in any manner the rights of the holders of the debt securities issued pursuant to such indenture. However, we and the trustee may not make any of the following changes to any outstanding debt security without the consent of each holder that would be affected by the change:

• extend the final maturity of any debt securities of any series or of any installment of principal of any such debt security;

• reduce the principal amount thereof;

• reduce the rate or extend the time of payment of interest thereon;

• reduce any amount payable on redemption thereof;

14

• make the principal thereof (including any amount in respect of original issue discount), or interest thereon, payable in any coin or currency other than that provided in the debt securities or in accordance with the terms thereof;

• modify or amend any provisions for converting any currency into any other currency as provided in the debt securities or in accordance with the terms of such debt securities;

• change our obligations, if any, to pay additional amounts established for any tax, assessment or governmental charge withheld or deducted, including any option to redeem the debt securities rather than to pay the additional amounts;

• reduce the amount of the principal of an original issue discount security that would be due and payable upon an acceleration of the maturity of such debt security (if applicable) or the amount provable in bankruptcy, or impair or affect the right of any holders of the debt securities to institute suit for the payment thereof or, if the debt securities provide therefor, impair or affect any right of repayment at the option of the holders of the debt securities;

• modify or amend any provisions relating to the conversion or exchange of any of the debt securities for other of our securities or for securities of other entities or for other property (or the cash value thereof), including the determination of the amount of securities or other property (or cash) into which such debt securities shall be converted or exchanged, other than as provided in the anti-dilution provisions or other similar adjustment provisions of such debt securities or otherwise in accordance with the terms of such debt securities;

• in the case of subordinated debt securities, modify or amend any provisions relating to the agreement to subordinate and the terms of subordination of the debt securities of any particular series pursuant to the subordinated indenture; or

• reduce the aforesaid percentage of any of the debt securities of any particular series, the consent of the holders of such series being required for any such supplemental indenture.

Concerning the Trustee

Unless otherwise specified in connection with a particular offering of debt securities, The Bank of New York Mellon will serve as the senior trustee and the subordinated trustee.

Any trustee appointed pursuant to the indentures will have and will be subject to all of the duties and responsibilities under the relevant indenture and those with respect to an indenture trustee under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

The indentures will provide that upon the occurrence of an event of default with respect to a series of senior debt securities (in the case of senior debt securities) or an event of acceleration or a default in the payment of interest or principal with respect to a series of subordinated debt securities (in the case of the subordinated debt securities), the trustee with respect to the relevant debt securities will exercise the rights and powers vested in it by the relevant indenture, using the same degree of care and skill as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. In the absence of such event of default, event of acceleration or default in the payment of interest or principal, the trustee need only perform those duties that are specifically set forth in the relevant indenture or are applicable pursuant to the Trust Indenture Act.

Subject to the relevant indenture and the provisions of the Trust Indenture Act, the trustee will be under no obligation to exercise any rights, trusts or powers conferred under the relevant indenture or the debt securities for the benefit of the holders of the debt securities, unless the holders have offered to the trustee indemnity and/or security reasonably satisfactory to the trustee against any loss, cost, liability or expense which might be incurred by it in exercising any such rights, trusts or powers.

15

The indentures will contain, and the Trust Indenture Act contains, limitations on the rights of the trustee thereunder, should it become a creditor of ours or any of our subsidiaries, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claims, as security or otherwise. The trustee is permitted to serve as trustee under the senior indenture while also serving as trustee under the subordinated indenture, and to engage in other transactions, provided that if it acquires any conflicting interest (as defined in Section 310(b) of the Trust Indenture Act), it must eliminate such conflict or resign.

The indentures will provide that we will indemnify the trustee and each predecessor trustee for, and to hold it harmless against, any loss, liability or expenses arising out of or in connection with the acceptance or administration of the relevant indenture or the trusts thereunder and the performance of such party’s duties thereunder, including reasonable and properly incurred costs and expenses of defending itself against or investigating any claim of liability, except to the extent such loss, liability or expense is due to the negligence or bad faith of the trustee or such predecessor trustee.

We and our subsidiaries and affiliates may maintain ordinary banking relationships and custodial facilities with any trustee or its affiliates.

Successor Trustee

The indentures will provide that the trustee may resign or be removed by us, effective upon acceptance by a successor trustee of its appointment. The indentures will require, and the Trust Indenture Act requires, that any successor trustee shall be a corporation with a combined capital and surplus of not less than $50,000,000 and shall be a corporation, association, company or business trust organized and doing business under the laws of the United States or any jurisdiction thereof or any state or territory or of the District of Columbia. No person may accept its appointment as a successor trustee with respect to the debt securities of a series unless at the time of such acceptable such successor trustee is qualified and eligible under the relevant indenture and the applicable provisions of the Trust Indenture act.

Repayment of Funds

The indentures will provide that all monies paid by us to a trustee or paying agent for a particular series of debt securities for payment of principal of or interest on any debt security which remains unclaimed at the end of two years after such payment shall be become due and payable will be repaid to us and all liability of the trustee or paying agent with respect thereto will cease, and to the extent permitted by law, the holder of such debt security shall thereafter only look to us for any payment which such holder may be entitled to collect.

Governing Law

The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York.

Consent to Jurisdiction and Service of Process

Under the indentures, we will irrevocably designate Sumitomo Mitsui Banking Corporation, New York Branch as our authorized agent for service of process in any legal action or proceeding arising out of or relating to the indentures or any debt securities brought in any federal or state court in The City of New York, New York, and we will irrevocably submit to the non-exclusive jurisdiction of those courts.

Limitation on Suits

Except for the right to institute a suit for the enforcement of the payment of principal of or interest that has become due and payable on a debt security, under the indenture and the debt securities, no holder of a debt

16

security shall have any right by virtue or availing of any provision of the relevant indenture to institute any proceeding against us with respect to the indenture or the debt security or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy thereunder, unless:

• such holder has previously given written notice to the trustee of a continuing default with respect to the debt security;

• the holders of not less than 25% in principal amount of the outstanding debt securities of each affected series issued under the relevant indenture (treated as a single class) shall have made written request to the trustee to institute proceedings and such holders have offered the trustee indemnity or security reasonably satisfactory to the trustee against the costs, expenses and liabilities to be suffered or incurred;

• the trustee for 60 days after its receipt of such notice, request and offer of indemnity or security has failed to institute any such proceeding; and

• no written direction inconsistent with such written request has been given to the trustee during such60-day period by the holders of a majority in principal amount of the outstanding debt securities of each affected series under the relevant indenture (voting together as a single class).

Undertaking for Costs

The indentures will provide that we and the trustee agree, and each holder of a debt security by his acceptance thereof shall be deemed to have agreed, that in any suit for the enforcement of any right or remedy under the relevant indenture or against the trustee for action taken, suffered or omitted by it as trustee (other than a suit instituted by the trustee, a holder or group of holders holding more than 10% in aggregate principal amount of the debt securities, or any holder for the enforcement of the payment of the principal of or interest on any debt security on or after the due date thereof), a court may in its discretion require the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant.

Form, Book-entry and Transfer

Each series debt securities will be issued in fully registered form without coupons. No service charge will be made for any registration of transfer or exchange of the debt securities, but we may require payment of a sum sufficient to cover any tax or government charge payable in connection therewith.

We will cause to be maintained offices or agencies where the debt securities may be presented for registration of transfer or for exchange, each, a transfer agent.

We will cause to be kept for the debt securities a register in which, subject to such reasonable regulations as we may prescribe, we will provide for the registration of such debt securities and registration of transfers of such securities. We, the trustee and any agent of ours or the trustee may treat the person in whose name any debt security is registered as the absolute owner of such debt security for all purposes and none of them shall be affected by any notice to the contrary. At the option of the registered holder of a debt security, subject to the restrictions contained in the debt securities and in the indenture, such debt security may be transferred or exchanged for a like aggregate principal amount of debt security of the same series of different authorized denominations, upon surrender for exchange or registration of transfer, at the trustee’s office. Any debt security surrendered for exchange or presented for registration of transfer shall be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to us and the trustee, duly executed by the holder thereof or its attorney duly authorized in writing. Debt securities issued upon any such transfer will be executed by us and authenticated by or on behalf of the trustee, registered in the name of the designated transferee or transferees and delivered at the trustee’s office or mailed, at the request, risk and expense of, and to the address requested by, the designated transferee or transferees.

17

We may vary or terminate the appointment of any transfer agent, or appoint additional or other transfer agents or approve any change in the office through which any transfer agent acts. We will cause notice of any resignation, termination or appointment of the trustee or any transfer agent, and of any change in the office through which any transfer agent will act, to be provided to holders of the debt securities.

Global Securities

The debt securities will be initially represented by one or more global certificates in fully registered form without interest coupons, or the global securities. The global securities will be deposited upon issuance with a custodian for DTC and registered in the name of DTC or its nominee. Beneficial interests in the global securities may be held only through DTC (or any successor clearing system that holds global securities) and its participants, including Euroclear and Clearstream. Each of DTC, Euroclear and Clearstream is referred to as a depositary.

Beneficial interests in the global securities will be shown on, and transfers thereof will be effected only through, records maintained by the depositaries and their participants. Except as set forth below, the global securities may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Accordingly, the sole holder of the debt securities represented by the global securities will at all times be DTC or its nominee (or a successor of DTC or its nominee), and voting and other consensual rights of holders of the debt securities will be exercisable by beneficial owners of the debt securities only indirectly through the rules and procedures of the depositaries from time to time in effect. Beneficial interests in the global securities may not be exchanged for definitive debt securities except in the limited circumstances described below under “—Exchanges of Global Securities for Definitive Debt Securities.”

Exchanges of Global Securities for Definitive Debt Securities

A beneficial interest in a global security may not be exchanged for a definitive debt security unless DTC notifies us that it is unwilling or unable to continue as depository for such global security or has ceased to be a clearing agency registered under the Exchange Act, and we do not appoint a successor depositary within 90 days. Upon the occurrence of such event, DTC shall instruct us to transfer the debt securities to such persons as notified to it by the applicable depositary or any successor clearance and settlement system as the holders of beneficial interests therein. In all cases, definitive debt securities delivered in exchange for any global security or beneficial interests therein will be registered in the names, and issued in approved denominations, requested by or on behalf of the applicable depositary (in accordance with its customary procedures). Any definitive debt security issued in exchange for an interest in a global security will bear a legend restricting transfers to those made in accordance with the restrictions set forth in the indenture.

Depositary Procedures

As long as DTC or its nominee is the registered holder of global securities, DTC or its nominee, as the case may be, will be considered the sole owner and holder of the debt security represented by such global securities for all purposes under the indenture and the debt security, and, accordingly, our obligations under the debt securities represented by such global securities are to DTC or its nominee, as the case may be, as the registered holder of such debt securities, and not to the holders of beneficial interests in such debt securities.

Transfer of beneficial interests in the global securities will be subject to the applicable rules and procedures of the depositaries and their respective direct or indirect participants, which may change from time to time.

DTC

DTC is a limited purpose trust company organized under the laws of the State of New York, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency”

18

registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions, such as transfers and pledges, among participants in deposited securities through electronic book-entry charges to accounts of its participants, thereby eliminating the need for physical movement of securities certificates. Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Certain of those participants (or other representatives), together with other entities, own DTC. The rules applicable to DTC and its participants are on file with the SEC.

Persons who are not DTC participants may beneficially own securities held by or on behalf of DTC only through DTC participants or indirect DTC participants. The ownership interest and transfer of ownership interest of each actual purchaser of each security held by or on behalf of DTC are recorded on the records of DTC participants and indirect DTC participants. DTC has also advised that, pursuant to its established procedures, upon deposit of the global securities, DTC will credit the accounts of DTC participants designated by the initial purchasers with portions of the principal amount of such global securities and ownership of such interests in the global securities will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC (with respect to DTC participants) or by DTC participants and indirect DTC participants (with respect to other owners of beneficial interests in the global securities).

Investors in the debt securities may hold their interests therein directly through DTC if they are participants in such system, or indirectly through DTC participants. All interests in a global security may be subject to the procedures and requirements of DTC. The laws of some states require that certain persons take physical delivery in certificated form of securities that they own. Consequently, the ability to transfer beneficial interests in a global security to such persons will be limited to that extent. Because DTC can act only on behalf of DTC participants, which in turn act on behalf of indirect DTC participants and certain banks, the ability of a person having beneficial interests in global securities to pledge such interests to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests. See “—Global Securities—Exchanges of Global Securities for Definitive Debt Securities.”

Except as described above under “—Global Securities—Exchanges of Global Securities for Definitive Debt Securities,” owners of interests in global securities will not have debt securities registered in their name, will not receive physical delivery of debt securities and will not be considered the registered owners or holders thereof for any purpose.

Payments in respect of global securities registered in the name of DTC or its nominee will be payable by the paying agent for the relevant debt securities to DTC or to the order of its nominee as the registered owner of the global securities. The paying agent will treat the persons in whose names the global securities are registered as the owners thereof for the purpose of receiving such payments and for any and all other purposes whatsoever. Consequently, neither we nor any agent of ours has or will have any responsibility or liability for any aspect of DTC’s records or any DTC participant’s or indirect DTC participant’s records relating to or payments made on account of beneficial ownership interests in the global securities, or for maintaining, supervising or reviewing any of DTC’s records or any DTC participant’s or indirect DTC participant’s records relating to the beneficial ownership interests in global securities or any other matter relating to the actions and practices of DTC or any of DTC participants or indirect DTC participants.

DTC has advised us that its current practice, upon receipt of any payment in respect of securities such as the debt securities, is to credit the accounts of the relevant DTC participants with the payment on the payment date unless DTC has reason to believe it will not receive payment on such payment date. Payments by the DTC participants and the indirect DTC participants to the beneficial owners of debt securities will be governed by standing instructions and customary practices, will be the responsibility of the DTC participants or the indirect DTC participants and will not be the responsibility of DTC or us. We and the relevant paying agent may conclusively rely upon and will be protected in relying upon instructions from DTC or its nominee for all purposes.

19

Interests in the global securities will trade in DTC’s Settlement System, and secondary market trading activity in such interests will therefore settle in immediately available funds, subject in all cases to the rules and procedures of DTC and DTC participants. Transfers between DTC participants will be effected in accordance with DTC’s procedures, and will be settled in same-day funds.

DTC has advised that it will take any action permitted to be taken by a holder of debt securities only at the direction of one or more DTC participants to whose account with DTC interests in the debt securities are credited. However, DTC reserves the right to exchange the global securities for legended definitive debt securities and to distribute such legended debt securities to DTC participants.

The information in this section concerning DTC and its book-entry systems has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof. Although DTC has agreed to the foregoing procedures to facilitate transfers of interest in the global securities among DTC participants, it is under no obligation to perform or to continue to perform such procedures, and such procedures may be discontinued at any time. We will not have any responsibility for the performance by DTC, DTC participants or indirect DTC participants of their respective obligations under the rules and procedures governing their operations.

Euroclear

Euroclear was created in 1968 to hold securities for its participants and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thus eliminating the need for physical movement of certificates and risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V., under contract with Euroclear Clearance Systems, S.C., a Belgian cooperative corporation. All operations are conducted by Euroclear Bank, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with Euroclear Bank, not with Euroclear Clearance Systems. Euroclear Clearance Systems establishes policies for Euroclear on behalf of Euroclear participants. Euroclear participants include banks, including central banks, securities brokers and dealers and other professional financial intermediaries and may include the initial purchasers. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly. Euroclear is licensed, regulated and examined by the Belgian Banking and Finance Commission.

Securities clearance accounts and cash accounts with Euroclear are governed by the terms and conditions governing use of, and the related operating procedures of, Euroclear and applicable Belgian law, which are referred to collectively as the terms and conditions. The terms and conditions govern transfers of securities and cash within Euroclear, and withdrawals of securities and cash from Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. Euroclear acts under the terms and conditions only on behalf of Euroclear participants and has no record of, or relationship with, persons holding through Euroclear participants.

Clearstream

Clearstream is incorporated as a bank under Luxembourg law. Clearstream holds securities for its participants and facilitates the clearance and settlement of securities transactions between Clearstream participants through electronic book-entry changes in accounts of Clearstream participants, thus eliminating the need for physical movement of certificates. Clearstream provides to its participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in a number of countries. Clearstream has established an electronic bridge with Euroclear to facilitate settlement of trades between Clearstream and Euroclear.

20

As a registered bank in Luxembourg, Clearstream is subject to regulation by the Luxembourg Commission for Supervision of the Financial Sector. Clearstream participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. In the United States, Clearstream participants are limited to securities brokers and dealers. Clearstream participants may include the initial purchasers. Other institutions that maintain a custodial relationship with a Clearstream participant may obtain indirect access to Clearstream.

Transfers among DTC, Clearstream and Euroclear

Transfers between DTC participants will be effected in the ordinary way in accordance with DTC rules and will be settled in same-day funds. Transfers between participants in Euroclear and Clearstream will be effected in the ordinary way in accordance with their respective rules and operating procedures.

Cross-market transfers between persons holding, directly or indirectly through DTC, on the one hand, and directly or indirectly through Euroclear or Clearstream participants, on the other, will be effected in DTC in accordance with DTC rules on behalf of the relevant European international clearing system by the relevant European depositary; however, those cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in that system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to the relevant European depositary to take action to effect final settlement on its behalf by delivering or receiving securities in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream participants may not deliver instructions directly to the European depositaries.

Because of time zone differences, credits of securities received in Euroclear or Clearstream as a result of a transaction with a person that does not hold the debt securities through Euroclear or Clearstream will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Those credits or any transactions in those securities settled during that processing will be reported to the relevant Euroclear or Clearstream participants on that business day. Cash received in Euroclear or Clearstream as a result of sales of securities by or through a Euroclear participant or a Clearstream participant to a DTC participant will be received with value on the DTC settlement date, but will be available in the relevant Euroclear or Clearstream cash account only as of the business day following settlement in DTC.

Limitation on Responsibilities

Although the foregoing sets out the procedures of the depositaries established in order to facilitate the transfer of interests in the global securities among their participants, none of the depositaries is under any obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time.

DTC, Euroclear and Clearstream have no knowledge of the actual beneficial owners of interests in a global security. DTC’s records reflect only the identity of the DTC participants to whose accounts those global securities are credited, which may or may not be the beneficial owners of interests in a global security. Similarly, the records of Euroclear and Clearstream reflect only the identity of the Euroclear or Clearstream participants to whose accounts global securities are credited, which also may or may not be the beneficial owners of interests in a global security. DTC, Euroclear and Clearstream participants and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

Neither we nor any underwriters of our debt securities, nor any of our or their respective agents will have any responsibility for the performance by any depositary or their respective participants of their respective obligations under the rules and procedures governing their operations.

21

Other Clearing Systems

We may choose any other clearing system for a particular series of debt securities. The clearance and settlement procedures for the clearing system we choose will be described in the applicable prospectus supplement.

22

TAXATION

The material Japanese tax and U.S. federal income tax consequences relating to the purchase and ownership of the securities offered by this prospectus will be set forth in the applicable prospectus supplement.

BENEFIT PLAN INVESTOR CONSIDERATIONS

The U.S. Employee Retirement Income Security Act of 1974, as amended, or ERISA, and Section 4975 of the Code, impose certain requirements on (a) employee benefit plans subject to Title I of ERISA, (b) individual retirement accounts, Keogh plans or other arrangements subject to Section 4975 of the Code, (c) entities whose underlying assets include “plan assets” of any such plan, account or arrangement described in clause (a) or (b) by reason of any such plan’s, account’s, or arrangement’s investment therein (we refer to the foregoing described in clauses (a), (b) and (c), collectively, as “Plans”) and (d) persons who are fiduciaries with respect to Plans. In addition, certain governmental, church and non-U.S. plans, or Non-ERISA Arrangements, are not subject to the prohibited transaction provisions of Section 406 of ERISA or Section 4975 of the Code, but may be subject to other laws that are substantially similar to the prohibited transaction provisions of Section 406 of ERISA or Section 4975 of the Code, each a Similar Law.

In addition to ERISA’s general fiduciary standards, Section 406 of ERISA and Section 4975 of the Code prohibit certain transactions involving the assets of a Plan and persons who have specified relationships to the Plan, i.e., “parties in interest” as defined in ERISA or “disqualified persons” as defined in Section 4975 of the Code (we refer to the foregoing, collectively, as “parties in interest”) unless exemptive relief is available under a statutory or administrative exemption. Parties in interest that engage in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and Section 4975 of the Code. Thus, a Plan fiduciary considering an investment in the debt securities should also consider whether such an investment might constitute or give rise to a prohibited transaction under ERISA or Section 4975 of the Code. For example, the debt securities may be deemed to represent a direct or indirect sale of property, extension of credit or furnishing of services between a party in interest and an investing Plan which would be prohibited unless exemptive relief were available under an applicable exemption. Such parties in interest include, without limitation, us, the trustee, the paying agent, calculation agent, the transfer agent and the registrar for the debt securities and the initial purchasers.

In this regard, each prospective purchaser that is, or is acting on behalf of, a Plan, and proposes to purchase the debt securities, should consider the exemptive relief available under the following prohibited transaction class exemptions, or PTCEs: (A) the in-house asset manager exemption (PTCE 96-23), (B) the insurance company general account exemption (PTCE 95-60), (C) the bank collective investment fund exemption (PTCE 91-38), (D) the insurance company pooled separate account exemption (PTCE 90-1) and (E) the qualified professional asset manager exemption (PTCE 84-14). In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code may provide a limited exemption for the purchase and sale of the debt securities and related lending transactions, provided that neither the party in interest nor its affiliates has or exercises any discretionary authority or control or render any investment advice with respect to the assets of the Plan involved in the transaction and provided further that the Plan pays no more, and receives no less, than adequate consideration in connection with the transaction (the so-called “service provider exemption”). There can be no assurance that any of these statutory or class exemptions will be available with respect to transactions involving the debt securities.

Each purchaser or holder of a debt security, and each fiduciary who causes any entity to purchase or hold a debt security, shall be deemed to have represented and warranted, on each day such purchaser or holder holds such debt securities, that either (i) it is neither a Plan nor a Non-ERISA Arrangement and it is not purchasing or holding the debt securities on behalf of or with the assets of any Plan or Non-ERISA Arrangement; or (ii) its purchase and holding of such bonds shall not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a similar violation of any provision of any applicable Similar Law.

23

The foregoing discussion is general in nature and is not intended to be all inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries, or other persons considering purchasing the debt securities on behalf of, or with the assets of, any Plan or Non-ERISA Arrangement, consult with their counsel regarding the potential applicability of Title I of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the purchase and holding of the debt securities.

Each purchaser and holder of a debt security will have exclusive responsibility for ensuring that its purchase and holding of the bond does not violate the fiduciary or prohibited transaction rules of ERISA or the Code or the provisions of any applicable Similar Law. Nothing herein shall be construed as a representation that an investment in the bonds would meet any or all of the relevant legal requirements with respect to investments by, or is appropriate for, Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement.

24

• to or through underwriters or dealers;

• by ourselves directly;

If underwriters are used in an offering of the debt securities, the debt securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The debt securities may be either offered to the public through underwriting syndicates represented by one or more managing underwriters or by one or more underwriters without a syndicate. Unless otherwise set forth in the prospectus supplement, the underwriters will not be obligated to purchase debt securities that are offered unless specified conditions are satisfied, and, unless otherwise set forth in the prospectus supplement, if the underwriters do purchase any debt securities, they will purchase all securities that are offered.

If SMBC Nikko Securities America, Inc. or any other broker-dealer affiliate of ours participates in the distribution of our securities, the offering will be conducted in accordance with the applicable requirements of Rule 5121 of the Financial Industry Regulatory Authority’s rules or any successor provisions.

In connection with underwritten offerings of the debt securities offered by this prospectus and in accordance with applicable law and industry practice, underwriters may over-allot or effect transactions that stabilize, maintain or otherwise affect the market price of the debt securities offered by this prospectus at levels above those that might otherwise prevail in the open market, including by entering stabilizing bids, effecting syndicate covering transactions or imposing penalty bids, each of which is described below.

• A stabilizing bid means the placing of any bid, or the effecting of any purchase, for the purpose of pegging, fixing or maintaining the price of a security.

25

• A syndicate covering transaction means the placing of any bid on behalf of the underwriting syndicate or the effecting of any purchase to reduce a short position created in connection with the offering.

• A penalty bid means an arrangement that permits the managing underwriter to reclaim a selling concession from a syndicate member in connection with the offering when offered securities originally sold by the syndicate member are purchased in syndicate covering transactions.

These transactions may be effected on an exchange or automated quotation system, if the debt securities are listed on that exchange or admitted for trading on that automated quotation system, or in the over-the-counter market or otherwise. Underwriters are not required to engage in any of these activities or to continue these activities if commenced.

If dealers are utilized in the sale of debt securities offered by this prospectus, we will sell the debt securities to the dealers as principals. The dealers may then resell the debt securities to the public at varying prices to be determined by the dealers at the time of resale. The names of the dealers and the terms of the transaction will be set forth in the prospectus supplement relating to that transaction.

Debt securities may be sold directly by us to one or more institutional purchasers, or through agents designated by us from time to time, at a fixed price or prices, which may be changed, or at varying prices determined at the time of sale. Any agent involved in the offer or sale of the debt securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to the agent will be set forth, in the prospectus supplement relating to that offering. Unless otherwise indicated in the applicable prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment.

If so indicated in the applicable prospectus supplement, we will authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase offered debt securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. These contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth the commission payable for solicitation of the contracts.

Underwriters, dealers and agents may be entitled, under agreements with us, to indemnification by us relating to material misstatements or omissions. Underwriters, dealers and agents may be customers of, engage in transactions with, or perform services for, us and our subsidiaries or affiliates in the ordinary course of business.

Each series of debt securities offered by this prospectus will be a new issue of securities and will have no established trading market. Any underwriters to whom offered securities are sold for public offering and sale may make a market in the offered debt securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The debt securities offered by this prospectus may or may not be listed on a national securities exchange. No assurance can be given that there will be a market for any debt securities offered by this prospectus.
