D.	Risk Factors

Risks Relating to Our Business

This annual report contains forward-looking statements such as forecasts of results of operations, management strategies, objectives and plans, forecasts of operational data such as the expected number of subscription, and the expected dividend payments. All forward-looking statements that are not historical facts are based on management’s current plans, expectations, assumptions and estimates based on the information currently available. Some of the projected numbers in this report were derived using certain assumptions that are indispensable for making such projections in addition to historical facts. These forward-looking statements are subject to various known and unknown risks, uncertainties and other factors that could cause our actual results to differ materially from those contained in or suggested by any forward-looking statement. Potential risks and uncertainties include, without limitation, the following:

Changes in the market environment in the telecommunications industry, such as intensifying competition from other businesses or other technologies caused by Mobile Number Portability, development of appealing new handsets, new market entrants, mergers among other service providers and other factors, or the expansion of the areas of competition and an increase in mobile communications operators entering into and collaborating with other industries could limit the acquisition of new subscriptions and retention of existing subscriptions by our corporate group, or it may lead to ARPU diminishing at a greater than expected rate, an increase in our costs, or an inability to optimize costs as expected.

Mobile Number Portability (“MNP”), the development of appealing handsets, the entry of new service providers, mergers among other service providers and other factors are intensifying competition for our corporate group from other service providers in the telecommunications industry. For example, other mobile service providers have introduced handsets that keep up with the needs and desires of customers, including handsets that support high-speed services and music/video playback, new services such as music and video distribution services, and flat-rate services for voice communications ande-mail, as well as installment sales methods for devices. If, in the future, other providers offer services that are more convenient or handsets that are more appealing to customers in the future, we may be unable to respond in a timely and suitable manner. If we are unable to build a network having a certain area and quality within the anticipated period of time, while other service providers build mobile communications networks with an area and quality that exceeds ours, customer satisfaction with our network may decline.

At the same time, competition is intensifying as a result of the introduction of other new services and technologies, especiallylow-priced and flat-rate services, such as fixed-line or mobile IP phones (including services that use applications that run on our smartphones and tablets), high-speed broadband Internet service, digital broadcasting, public wireless LAN usingWi-Fi, free orlow-priced services of OTT^*1 service providers, the provision of SIM^*2 cards, or a combination of these services.

In addition to competition from other service providers and technologies in the telecommunications industry, there are other factors increasing competition among mobile network operators, such as saturation in the Japanese mobile communications market, changes to business and market structures and the environment due to the expansion of the areas of competition arising from the entry of competitors in the market, including MVNOs^*3 and competitors from other industries. In particular, there is an upward trend in the number of users choosinglow-cost services provided by MVNOs. With the use of open platform devices like smartphones and tablets becoming increasingly widespread, many businesses and others have entered the competition in service offerings on mobile phones, and in addition, the wholesale optical-fiber access service offered by NIPPON TELEGRAPH AND TELEPHONE EAST CORPORATION (“NTT East”) and NIPPON TELEGRAPH AND TELEPHONE WEST CORPORATION (“NTT West”) started a wholesale optical-fiber access service which enables a diverse group of market participants to provide services utilizing optical-fiber connections and set discounts for fixed and mobile network services, so it is possible that such businesses and others may eventually launch services that are more convenient for customers, and further intensify rateprice competition. Moreover, there has been an increase inIn addition, mobile communications operators are actively entering into and

collaborating within other industries including due to factors such as the full liberalization ofenergy market, smart-home market^*4, sports business market, FinTech projects^*5 and projects that utilize big data, and it is possible that the electricity market,attractive services offered by our competitors will lead to a slump in customer satisfaction levels with our company and ratethat price competition couldwill intensify due toas mobile communications operators offer bundle discounts for packages incorporatingthat include services provided by operators in different industries.other sectors.

In this market environment, the decline in the number of net new subscriptions we acquire may accelerate in the future and the number of net new subscriptions we acquire may not reach the number we expect. Also, we may not be able to maintain existing subscriptions as customers migrate to other service providers due to increased competition. Furthermore, in order to capture new subscriptions and maintain existing subscriptions, there could be a greater-than-expected decline in ARPU and/or greater-than-expected costs. ToIn order to provide advancedhighly diverse services and increaseimprove convenience tofor our customers under suchin a challenging market conditions,environment, we have madebeen revising various revisions, such as the provision of discounted services for each rate type. For example, we introducedpricing plans and discount services, with aservices offering fixed discount from thediscounts set for different models of devices on monthly usage charges set for each type, and introduced fee plans for flat-ratefixed rate domestic voice calls. These pricing plans and discount services include the following the “Kake-hodai & Pake-aeru” which enable customerspricing plan that offers quantities of packet network data to set and share monthly data quotas withamong family andmembers; the “Zutto DOCOMO Wari,” aWari” discount service for long-term customers, andusers; the “U25 Ouen Wari” discount plan aimed at customers aged 25 or younger; the “docomo Hikari Pack” that offers a combination of the “docomo Hikari” service and smartphone/feature phone handsets; the “Kake-hodai Light Plan” pricing plan for low volume users; the “Simple Plan” pricing plan for users who basically make calls with their family members; the “Ultra Pack” pricing plans for high data users; and the “docomo with” discount plan for customers under 25 yearsusers who intend to use one handset for long period of age. In addition, we introduced “docomo Hikari Pack,” which provides the “docomo Hikari” optical-fiber broadband service together with smartphones or mobile phones. In the current fiscal year, we also introduced “Kake-hodai Light Plan” and “Share pack 5” as new rate plans for light users.time. However, we cannot be certain that these revisions will enable us to acquire new and maintain existing subscriptions. It is also possible that the subscription ratio for various discount services or the trend in migration to flat-rate services may not be in line with our group’s expectations, and our ARPU may decrease more than projected. Furthermore, if market growth slows or the market shrinks, ARPU may decrease even more than our forecast and we may not be able to capture new subscriptions or maintain the existing number of subscriptions at the level we expect. In addition, in order to reinforce our managerial structure, we are promoting increased efficiency related to our network, sales and services, research and development and narrowing our productline-up to concentrate resources. The push toward greater efficiency, however, may not proceed as expected, and costs may not be optimized as anticipated due to intense competition from other service providers and changes in the market environment.

These foregoing factors may have a material adverse effect on our financial condition and operating results.

If current and new services, usage patterns, and sales schemes proposed and introduced by our corporate group cannot be developed as planned, or if unanticipated expenses arise the financial condition of our corporate group could be affected and our growth could be limited.

We view increases in revenue as an important factor in our future growth. We aim to increase revenue by, for instance, promoting the more widespread use of smartphone services and of LTE (Xi) services, as well as the expansion of the use of packet communications and other data communications in relation to such services. Moreover, we look to increase returns through “smart life business” segment and “other businesses” segment as another important factor in future growth. However, a number of uncertainties may arise to prevent the development of these services and constrain our growth. For more information regarding “smart life business” and “other businesses” segments and the scope of the services that we provide through them, please see “B.4. Services” in Item 4.

Furthermore, if market growth slows or the market shrinks, the services, forms of usage, and sales methods provided by us may not develop sufficiently which could affect our financial conditions and limit our growth. In particular, we cannot be certain as to whether or not the following can be achieved:

If the development of our corporate group’s new services, forms of use or sales methods is limited or if development costs are more than anticipated, or alternatively if we cannot secure and train the necessary human resources and manage the labor force as required to operate our business as we expect or on schedule, it may have a material adverse effect on our financial condition and results of operations.

The introduction or change of various laws or regulations inside and outside of Japan, or the application of such laws and regulations to our corporate group, could restrict our business operations, which may adversely affect our financial condition and results of operations.

The Japanese telecommunications industry has been undergoing regulatory reform in many areas, including rateprice regulation. Because we operate on radio spectrum allocated by the Japanese government, the mobile telecommunications industry in which we operate is particularly affected by the regulatory environment. Furthermore, in some cases, our group is subject to special regulations that are not imposed on other providers. Various governmental bodies have been recommending or considering changes that could affect the mobile telecommunications industry, and there may be continued reforms, including the introduction or revision of laws, regulations, or systems that could have an adverse effect on us. These include:

In addition to the above proposed changes that may impact the mobile communications business, we may be impacted by a variety of laws, regulations, and systems inside and outside of Japan. For example, in response to an increase in the number of subscriptions or in the traffic* per subscriber, we have proceeded with the enhancement of our telecommunications facilities in order to ensure and improve our service quality. As a result, weWe are using an increasing amount of electricity. Moreover, we are implementing

measures directed towards reducing greenhouse gas emissions, including deployment oflow-power consumption devices and efficient power generators. However, with the implementation of regulations and other measures aimed at reducing greenhouse gas emissions, our cost burdens may increase, and this may have an adverse effect on our financial condition and results of operations. Also, the financial condition and operating results of our corporate group may be adversely affected by the increased cost of maintaining and operating the facilities we require for providing our services on account of electricity cost increases due to high fuel prices. In July 2010 the “Dodd–Frank Wall Street Reform and Consumer Protection Act” was signed into law in the United States. Based on this, the U.S. Securities and Exchange Commission established rules in August 2012 requiring listed companies that use designated minerals in their products to disclose whether such minerals come from the Democratic Republic of the Congo and adjoining countries. The implementation of these rules could have an adverse effect on our financial condition and operating results in the form of higher costs arising from expense of conducting the research needed for regulatory compliance or from an increase in the prices of materials that use such minerals.

Further still, in order to ensure new sources of revenue, we are pursuing “+d” initiatives to create new value through the convergence of mobile services with various services and industries. Therefore, we are vulnerable to

the impact of laws, regulations and systems specific to new services, operations and areas of business, in addition to the laws, regulations and systems applicable to the mobile communications business. If such laws, regulations, or systems are implemented, they may work as constraints on our group’s business operations, and this may have an adverse effect on our group’s financial condition and corporate performance.

It is difficult to predict with certainty if any proposed changes impacting the mobile telecommunications business, or if any other relevant laws, regulations or systems will be drafted, and if they are implemented, the extent to which our business will be affected. However, if any one or more of the above proposed changes impacting the mobile telecommunications business occurs, or if laws, regulations or systems are introduced, reformed, or become applicable to us, we may experience constraints on the provision of our mobile communication services, which may have an adverse effect on our financial condition and results of operations.

Limitations in the amount of frequency spectrum or facilities made available to us could negatively affect our ability to maintain and improve our service quality and level of customer satisfaction and could increase our costs.

One of the principal limitations on a mobile communication network’s capacity is the available radio frequency spectrum we can use. There are limitations in the spectrum and facilities available to us to provide our services. As a result, in certain parts of metropolitan Tokyo and Osaka, such as areas near major train stations, our mobile communication network operates at or near the maximum capacity of its available spectrum during peak usage periods, which may cause reduced service quality.

Furthermore, with the number of subscriptions and traffic^* per subscriber increasing, our service quality may decline if we cannot obtain the necessary allocation of spectrum from the Japanese government for the smooth operation of our business.

Also, in order for us to establish specified base stations to use the radio frequencies allocated to us, it may require (i) measures for the acceleration of the transfer of existing radio stations that are currently using the same spectrum for other uses or (ii) discussion regarding agreements to share the same spectrum. If measures for the acceleration or discussion do not proceed as planned, our corporate group may not be able to operate its mobile communication network smoothly, service quality may decline, and additional expenses may arise.

Although we are working to improve the efficiency of our spectrum use through technology such asLTE/LTE-Advanced, including migration to LTE and other measures and to acquire additional spectrum, we may be unable to avoid a reduced quality of services.

In addition, due to the limited processing capacity of our base stations, switching facilities, and other equipment necessary for providing services, the quality of the services we provide may also decrease during peak usage periods if our subscription base dramatically increases or the volume of content such as imagesvideos and music provided through our networks significantly expands. Also, in relation to our FOMALTE (Xi) and LTE (Xi)FOMA services, the growth in the number of service subscribers and traffic per subscriber could significantly exceed our expectations due to the proliferation of smartphones and tablets as well as data communication devices for PCs. Furthermore, some of the software that runs on smartphones and tablets could result in greater use of control signals (the signals exchanged between devices and the network) in order to establish and terminate communications, and could therefore put a greater-than-anticipated burden on our facilities. If it becomes impossible to process such traffic using our existing equipment, service quality may deteriorate, communication interruptions may arise and the cost of investing in equipment to address these issues could increase.

We are endeavoring to reinforce the network foundation in order to cope with future increases in smartphone traffic. If unforeseen circumstances should arise, such as communication interruptions due to an increase in the number of subscribers and traffic and/or control signals per subscriber, and we are not able to

address such problems sufficiently and in a timely manner, our ability to provide mobile communication services could be constrained or we could lose customers’ trust, and as a result, we could lose subscribers to our competitors. At the same time, the cost of investing in equipment to address these issues could increase, and this could materially affect our financial condition and results of operations.

Other mobile service providers in the world may not adopt the technologies and the frequency bands that are compatible with those used by our corporate group’s mobile communications system on a continuing basis, which could affect our ability to sufficiently offer international services.

We are able to offer global roaming services on a worldwide basis on the condition that a sufficient number of other mobile service providers have adopted technologies and frequency bands that are compatible with those we use on our mobile communications systems. We expect that our overseas affiliates, strategic partners and many other mobile service providers will continue to use the technologies and the frequency bands that are compatible with ours, but there is no guarantee of this in the future.

If a sufficient number of mobile service providers do not adopt the technologies and the frequency bands that are compatible with ours, if mobile service providers switch to other technologies or frequency bands, or if there is a delay in the introduction and expansion of compatible technologies and frequency bands, we may not be able to offer international roaming or other services as expected, and we may not be able to offer our subscribers the convenience of overseas services.

Also, we cannot be sure that handset manufacturers or manufacturers of network equipment will be able to appropriately and promptly adjust their products if we need to change the handsets or network we currently use due to a change in the standard technology we adopt, resulting from the activities of standards organizations.

If such technologies and frequency bands compatible with those we have adopted do not develop as we expect and if we are not able to maintain or improve the quality of our overseas services, our financial condition and results of operations may be adversely affected.

Our domestic and international investments, alliances and collaborations, as well as investments in new business fields, may not produce the returns or provide the opportunities we expect.

One of the major components of our strategy is “+d” initiatives to increase our corporate value through domestic and overseas investments, alliances and collaborations. We have entered into alliances and collaborations with other companies and organizations overseas which we believe can assist us in achieving this objective. We are also promoting this strategy by investing in, entering into alliances with, and collaborating with domestic companies and investing in smart life business and other businesses.

However, there can be no assurance that we will be able to maintain or enhance the value or performance of the past or future investments or joint ventures established, or that we will receive the returns or benefits we expect from these investments, alliances and collaborations. In our investments in smart life business and other businesses anticipated synergies may not be realized due to uncertain and unforeseeable ancillary factors, as we have little experience in such businesses, and these factors may have an impact on our strategy. Furthermore, losses may arise due to dissolution or divestiture of investments, alliances and collaborations.

In recent years, the companies in which we have invested have experienced a variety of negative impacts, including severe competition, increased debt burdens, significant change in share prices and financial difficulties. To the extent that these investments are accounted for by the equity method and to the extent that the investee companies have net losses, our financial results will be adversely affected by ourpro rata portion of these losses. If there is a loss in the value of our investment in any investee company and it is not regarded as a temporary decline, our corporate group may be required to adjust the book value and recognize an impairment loss for such investment. Also, a business combination or other similar transaction involving any of our investee companies could require us to realize impairment loss for any decline in the value of investment in such investee company. In either event, our financial condition or results of operations could be materially adversely affected.

Malfunctions, defects or imperfections in our products and services or those of other parties may give rise to problems.

Various functions are mounted on the mobile handsets we provide. Additionally, a large number of vendors, including our partners and other companies, provide services via the mobile handsets that we provide. If any problems arise due to the imperfection in a product or service provided by the Company or by another vendor such as technological problems in the handsets provided by us or by outside vendors or in software or systems, or if any other failures, defects, or losses arise, such problems could diminish our credibility or corporate image, lead to an increase in cancellations of subscriptions, or result in an increase in expenses for indemnity payments to subscribers, and our financial condition or results of operations may be affected. Furthermore in an effort to ensure new sources of revenue, we are pursuing initiatives toward the expansion of smart life business segment and other businesses segment. Should problems arise due to imperfections in products or services we offer through smart life business and other businesses segments, such problems could diminish our credibility or corporate image and our financial condition or results of operations may be affected. Certain events may lead to a decrease in our credibility and corporate image, an increase in cancellations of subscriptions or increased costs. The following are possible examples of such events:

Social problems that could be caused by misuse or misunderstanding of our products and services may adversely affect our credibility or corporate image.

We may face an increase in cancellations of subscriber contracts and difficulty in acquiring new subscriptions due to decreased credibility of our products and services and damaged corporate image caused by inappropriate use of our products and services by subscribers.

For example, there are cases of unsolicited bulke-mails being sent through oure-mail services, including docomo mail,sp-mode mail,i-mode mail and SMS. Despite our extensive efforts to address this issue caused by unsolicited bulke-mails, including notifying our subscribers via various brochures, providing unsolicited bulke-mail filtering functions with our handsets and suspending our services to companies which distribute large amounts of such unsolicited bulke-mails, the problem has not yet been rooted out. If our subscribers receive a large amount of unsolicitede-mail, it may cause a decrease in customer satisfaction and may damage our corporate image, leading to a reduction in the number ofsp-mode ori-mode subscriptions.

The mobile phones used in connection with crimes such as billing fraud are most often rental mobile phones. To combat these misuses of our services, we have introduced various measures such as refusing to

provide services to unscrupulous mobile phone rental companies that violate the Mobile Phone Improper Use Prevention Act, such as by not confirming the identity of the individual at the time of rental. However, in the event that criminal usage increases, mobile phones may be regarded as a societal problem, which may lead to an increase in the cancellation of contracts.

In addition, problems have arisen from the fact that subscribers were charged fees for packet communication at higher levels than they anticipated as a result of using mobile phones without fully recognizing the increased volume and frequency of the use of packet communications as our handsets and services became more sophisticated. There have also been problems with high charges due to excessive use of paid content services, and problems due to an increasing amount of trouble and number of accidents caused by the use of smartphones or other mobile phonesdevices while driving, riding a bicycles or walking. Further,Furthermore, there are currently a variety of discussions concerning such issues as the pros and cons of elementary and junior high schools students having mobile phones, the sufficiency and accuracy of our access restriction service to screen harmful web sites (“filtering service”), which applies generally to subscribers under 18 years of age in accordance with the enactment of the Act on Establishment of Enhanced Environment for Youth’s Safe and Secure Internet Use, and the increase in harm caused by the use of CGM* SNS^*by young people, as they increasingly have access to the Internet from their mobile phones. These issues may similarly damage our corporate image.

We believe that we have properly addressed the social issues involving mobile phones by providing various services such as a filtering service andaccess restriction services with user age authentication and cellmobile phones specifically designed for young people. However, it is uncertain whether we will be able to continue to respond appropriately to those issues in the future. Should we fail to do so, we may experience an increase in the cancellation of existing subscriber contracts or fail to acquire new subscribers as expected, and this may affect our financial condition and results of operations.

Inadequate handling of confidential business information including personal information by our corporate group, contractors and others, may adversely affect our credibility or corporate image.

We possess information on numerous subscribers in telecommunications, smart life and other businesses, and to appropriately and promptly address the Law Concerning the Protection of Personal Information, we have put in place comprehensive company-wide security management that includes thorough management of confidential information such as personal information, employee education, supervision of subcontractors and the strengthening technological security.

However, in the event an information leak occurs despite these security measures, our credibility and corporate image may be significantly damaged and we may experience an increase in cancellation of subscriber contracts, an increase in indemnity costs and slower increase in additional subscriptions, and our financial condition and results of operations may be adversely affected.

Owners of intellectual property rights that are essential for our business execution may not grant us a license or other use of such intellectual property rights, which may result in our inability to offer certain technologies, products and/or services, and our corporate group may also be held liable for damage compensation if we infringe the intellectual property rights of others. In addition, the illicit use by a third party of the intellectual property rights owned by our corporate group could reduce our license revenues actually obtained and may inhibit our competitive superiority.

For us and our business partners to carry out our business, it is necessary to obtain licenses and other rights to use the intellectual property rights of third parties. Currently, we are obtaining licenses from the holders of the rights concerned by concluding license agreements. We will obtain the licenses from the holders of the rights concerned if others have the rights to intellectual property necessary for us to operate our business in the future.

However, if we cannot come to an agreement with the holders of the rights concerned or a mutual agreement concerning the granted rights cannot be maintained afterwards, there is a possibility that we or our business partners might not be able to provide our specific technologies, products or services. Also, if we receive claims of violation of intellectual property rights from others, we may be required to expend considerable time and expense to reach a resolution. If such claims are acknowledged, we may be liable to pay damages for infringement of the rights concerned, which may adversely affect our financial condition and results of operations.

Furthermore, the illicit use by a third party of the intellectual property rights owned by our corporate group could reduce our license revenues actually obtained and may inhibit our competitive superiority.

Events and incidents caused by natural disasters, social infrastructure paralysis such as power shortages, the proliferation of harmful substances, terror or other destructive acts, the malfunctioning of equipment, software bugs, deliberate incidents induced by computer viruses, hacking, unauthorized access, cyberattacks, equipment misconfiguration hacking, unauthorized access and other problems could cause failure in our networks, distribution channels, and/or other factors necessary for the provision of service, disrupting our ability to offer services to our subscribers, and such incidents may adversely affect our credibility or corporate image, or lead to a reduction of revenues and/or increase of costs.

We have built a nationwide network, including base stations, antennas, switching centers and transmission lines, and provide mobile communication service using this network. In order to operate our network systems in a safe and stable manner, we have various measures in place, such as duplicative systems. However, despite these measures, our system could fail for various reasons, including malfunctioning of system hardware and software, natural disasters such as earthquakes, tsunamis, typhoons and floods, paralysis of social infrastructure, such as power shortages, terrorism, and similar events and incidents, and the inability to sufficiently operate and maintain network facilities due to, for example, the proliferation of harmful substances or the spread of an epidemic. These system failures can require an extended time for repair and, as a result, may lead to decreased revenues and significant cost burdens, and our financial condition and results of operations may be adversely affected.

There have been instances in which tens of millions of computers worldwide were infected by viruses through fixed line Internet connections. As smartphones become more widespread, however, a growing number of viruses are also targeting mobile handsets. Similar incidents could occur on our networks, handsets, or other equipment. If such a virus entered our network or handsets or other equipment through such means as hacking, unauthorized access, or otherwise, or if there was a cyber -attack, our system could fail, the services we provide could become unusable, service quality could be impacted and/or confidential information could be leaked. In such an instance, the credibility of our network, handsets and other equipment and customer satisfaction could

decrease significantly. Although we have enhanced security measures including systems to block unauthorized access, remote downloading for mobile phones, and the provision of “Anshin Net Security,” an antivirus solution for smartphones in order to provide for unexpected events, such precautions may not make our system fully prepared for every contingency. Moreover, software bugs, incorrect equipment settings, and human errors that are not the result of malfeasance could also result in system failures, diminished service quality, or leaks of confidential information.

In addition, events or incidents caused by natural disasters, social infrastructure paralysis, the proliferation of harmful substances, the spread of an epidemic, or any other event could force our offices or critical business partners, including sales agencies, to suffer constraints on business operations or to temporarily close their offices or stores. In such a case, we would lose the opportunity to sell or provide goods and services and also may not be able to respond appropriately to subscription applications and requests from subscribers, such asafter-sales service requests.

If we are unable to properly respond to any such events, our credibility or corporate image may decrease, and we may experience a decrease in revenues as well as significant cost burdens, and if market growth slows or

the market shrinks due to any such event, ARPU may decrease below our forecast, or we may not be able to gain new subscriptions or maintain the existing number of subscriptions at the level we expect. All of these factors may affect our financial condition and results of operations.

Concerns about adverse health effects arising from wireless telecommunications may spread and consequently adversely affect our financial condition and results of operations.

Through various media sources and the internet, information has been disseminated indicating that there is concern about whether radio wave emissions from mobile handsets and other wireless telecommunications devices may adversely affect people’s health or may interfere with electronic medical devices including hearing aids and cardiac pacemakers. Such concerns about the possible risks associated with wireless telecommunication devices could adversely affect our corporate image, financial condition, and results of operations through increased cancellations by existing cellularmobile telecommunications services subscribers, reduced subscriber growth, reduced usage per subscriber, and the introduction of new regulations or restrictions or litigation. The radio emissions from our cellular handsets and base stations comply with the electromagnetic safety guidelines established by the Japanese government, which are equivalent to the international guidelines of the International Commission onNon-Ionizing Radiation Protection, which are endorsed by the World Health Organization “WHO.” The WHO has also stated that if the level of the radio emissions from mobile devices is lower than the international guidelines, it will not affect the health of their users and others. Research and studies on the effect of radio wave emissions on people’s health are being conducted by foreign research institutes such as the WHO and the Ministry of Internal Affairs and Communications, or the MIC. While no evidence of an adverse effect on people’s health has been found as of yet, there can be no assurance that, going forward a link between radio wave emissions and health problems will not be identified in the results of future research or studies.

Furthermore, MIC and the Electromagnetic Compatibility Conference Japan have confirmed that electronic medical devices such as cardiac pacemakers can be affected by electromagnetic interference from cellularmobile phones and other wireless equipment, and has created guidelines on safe usage to provide information to the general public. We are working to provide information to ensure that our subscribers are sufficiently aware of these precautions when using cellularmobile phones. There is a possibility that modifications to regulations and new regulations or restrictions could limit our ability to expand our market or our subscription base or otherwise adversely affect us.

Our parent company, NTT, could exercise influence that may not be in the interests of our other shareholders.

As of March 31, 2016,2017, NTT owned 65.66%66.65% of our outstanding voting shares. While being subject to the conditions for fair competition established by the Ministry of Posts and Telecommunications (currently the MIC) in April 1992, NTT retains the right to control our management as a majority shareholder, including the right to

appoint directors. Currently, although we conduct ourday-to-day operations independently of NTT and its other subsidiaries, certain important matters are discussed with, or reported to, NTT. As such, NTT could take actions that are in its best interests but may not be in the interests of our other shareholders.

Risks Relating to the Shares and the ADSs

Future sales of our shares by NTT or by us may adversely affect the trading price of our shares and ADSs.

As of March 31, 2016,2017, NTT owned 65.66%66.65% of our outstanding voting shares. Under Japanese law, NTT, like any other shareholder, generally is able to dispose of our shares freely on the Tokyo Stock Exchange or otherwise. Additionally, our Board of Directors is authorized to issue 13,501,457,00013,560,437,000 additional shares generally without any shareholder approval. The sale or issuance or the potential for sale or issuance of such shares could have an adverse impact on the market price of our shares.

There are restrictions on your ability to withdraw shares from the depositary receipt facility.

Each ADS represents the right to receive one share of common stock. Therefore, pursuant to the terms of the deposit agreement with our depositary, The Bank of New York Mellon, in order to withdraw any shares, a holder

of ADSs must surrender for cancellation and withdrawal of shares using ADRs (each of which evidences 1ADSs). As a result, holders of ADSs will be unable to withdraw fractions of shares from the depositary or receive any cash settlement in lieu of withdrawal of fractions of shares. In addition, although the ADSs themselves may be transferred in any lots pursuant to the deposit agreement, the ability to trade the underlying shares may be limited.

Holders of ADRs have fewer rights than shareholders and have to act through the depositary to exercise those rights.

Holders of ADRs do not have the same rights as shareholders and accordingly cannot exercise rights of shareholders against us. The Bank of New York Mellon, as depositary, through its custodian agent, is the registered shareholder of the deposited shares underlying the ADSs, and therefore only it can exercise the rights of shareholders in connection with the deposited shares. In certain cases, we may not ask The Bank of New York Mellon to ask holders of ADSs for instructions as to how they wish their shares voted. Even if we ask The Bank of New York Mellon to ask holders of ADSs for such instructions, it may not be possible for The Bank of New York Mellon to obtain these instructions from ADS holders in time for The Bank of New York Mellon to vote in accordance with such instructions. The Bank of New York Mellon is only obliged to try, as far as practical, and subject to Japanese law and our Articles of Incorporation, to vote or have its agents vote the deposited shares as holders of ADSs instruct. In your capacity as an ADS holder, you will not be able to bring a derivative action, examine the accounting books and records of the Company, or exercise appraisal rights.

U.S. investors may have difficulty in serving process or enforcing a judgment against us or our directors, executive officers or audit & supervisory board members.

We are a limited liability, joint stock corporation incorporated under the laws of Japan. Most of our members of the board of directors, executive officers and audit & supervisory board members reside in Japan. All or substantially all of our assets and the assets of these persons are located in Japan and elsewhere outside the United States. It may not be possible, therefore, for U.S. investors to effect service of process within the United States upon us or these persons or to enforce against us or these persons judgments obtained in U.S. courts predicated upon the civil liability provisions of the Federal securities laws of the United States. There is doubt as to the enforceability in Japan, in original actions or in actions for enforcement of judgment of U.S. courts, of liabilities predicated solely upon the federal securities laws of the United States.

Rights of shareholders under Japanese law may be different from rights of shareholders in jurisdictions within the United States.

Our Articles of Incorporation, Regulations of the Board of Directors and the Companies Act of Japan (Kaishaho,or Companies Act) govern our corporate affairs. Legal principles relating to such matters as the validity of corporate procedures, directors’ and officers’ fiduciary duties and liabilities, and shareholders’ rights under Japanese law may be different from those that would apply to a company incorporated in a jurisdiction within the United States. You may have more difficulty in asserting your rights as a shareholder than you would as a shareholder of a corporation organized in a jurisdiction within the United States.

We expect voluntarily to delist our ADSs from the NYSE and we plan to effect deregistration and termination of ouron-going reporting obligations under the Securities Exchange Act of 1934.

On April 28, 2016, we announced that our Board of Directors resolved to apply for voluntary delisting of our ADSs from the New York Stock Exchange (the “NYSE”) around March 2018. In connection with the delisting, we intend to file for the termination of registration of our ADSs and of ouron-going reporting obligations under the U.S. Securities Exchange Act of 1934 in around March 2018. After the delisting of our ADSs from the NYSE, we intend to maintain our ADR Program in the U.S. and therefore anticipate that our ADSs will continue to be traded in the U.S. on theover-the-counter market. The market for our ADSs may be significantly less liquid following our delisting of our ADSs from the NYSE.

Furthermore, while we currently prepare and disclose our financial statements in accordance with U.S. GAAP, the Company iswe are considering preparing and disclosing its financial statements in accordance with International Financial Reporting Standards (“IFRS”) beginning with the three months ending June 30, 2018.

Our shareholders of record on a record date may not receive the dividend they anticipate.

The customary dividend payout practice and relevant regulatory regime of publicly listed companies in Japan may differ from that followed in foreign markets. While we may announce forecasts ofyear-end and interim dividends prior to the record date, these forecasts are not legally binding. The actual payment ofyear-end dividends requires a resolution of our shareholders. If the shareholders adopt such a resolution, theyear-end dividend payment is made to shareholders as of the applicable record date, which is currently specified as March 31 by our Articles of Incorporation. However, such a resolution of our shareholders is usually made at an ordinary general meeting of shareholders held in June. The payment of interim dividends requires a resolution of our Board of Directors. If the board adopts such a resolution, the dividend payment is made to shareholders as of the applicable record date, which is currently specified as September 30 by our Articles of Incorporation. However, the board usually does not adopt a resolution with respect to an interim dividend until September 30.

Shareholders of record as of an applicable record date may sell shares after the record date in anticipation of receiving a certain dividend payment based on the previously announced forecasts. However, since these forecasts are not legally binding and resolutions to pay dividends are usually not adopted until after the record date, our shareholders of record on record dates foryear-end or interim dividends may not receive the dividend they anticipate.

The Company engages in telecommunications, smart life and other businesses. For more information regarding our business segments, please see “B.4. Services” in Item 4.

We operate our business mainly in Japan, and do not generally experience significant seasonality.

Breakdown of Operating Revenues

The environment forof Japan’s telecommunications market has significantly changed in recent years. Especially in the mobile communicationstelecommunications market, is significantly changingcompetition has intensified due to the rapid penetrationgovernment’spro-competition policies, the rise of smartphones/tabletslow-cost smartphones offered by MVNOs and other factors. Also, in the fixed communications market, not only telecommunications operators but also various other players have started to government policies to promote competitionprovide new services using the “Hikari Collaboration Model” (as described below). Furthermore, significant changes are also apparent in areasthe business models of telecommunications operators, as advances in mobile ICT, such as the new entry of MVNOs, the mandatory unlocking of SIM cardsin devices and the MIC’s proposal of the “Task Force on Review of Services form Users’ View Point”networks have resulted in operators actively entering and the “Task Force on Mobile Phone Rates andcollaborating in other Conditions.”sectors.

There are presently three mobile network operators in Japan: DOCOMO, KDDI CORPORATION and its subsidiaries (“KDDI group”) and SoftBank Corp. and its subsidiaries (“SOFTBANK group”). As of March 31, 2016,

2017, we had a market share of 45.3%46.0%, KDDI group had a market share of 29.3%29.8% and SOFTBANK group had a market share of 25.3%24.2%. Note that each company’s share also includes lines that the individual company provides for MVNOs.

As of March 31, 20162017 we had approximately 70,96474,880 thousand cellularmobile telecommunications subscribers, an increase of approximately 4,3683,916 thousand from the end of the previous fiscal year. Also, our cellular churn rate for March 20162017 was 0.62%0.59%.

Although future growth of new subscribers for conventional voice use is expected to be limited as the penetration rate rises and the population declines, in recent years, the development of new markets for products such as demand for second devices such as tablets and mobileWi-Fi routers, in addition to embedded communication modules, and rising numbers of subscribers due to an increase in corporate subscriptions, have helped drive growth in new subscriptions.

The number of cellularmobile telecommunications services subscriptions for the fiscal years ended March 31, 2014, 2015, 2016 and 20162017 are as follows:

*1 The calculation method of churn rate has been changed from the fiscal year ended March 31, 2016. Accordingly, the churn rates for the fiscal year ended March 31, 2014 and 2015 have also been changed. Data are calculated excluding the subscriptions and cancelation of subscriptions of Mobile Virtual Network Operators (MVNOs).

*2* Active cellularmobile telecommunications services subscriptions = (number of subscriptions at the end of previous month + number of subscriptions at the end of current month) / 2

Furthermore in the fixed-line communications market, the “Hikari Collaboration Model,” which is a wholesale business model for fiber access that commenced in February 2015,Model” mentioned above, has enabled telecommunications operators and a wide range of other players to provide services utilizing optical fiber, andfiber. Accordingly, competition transcending the traditional boundaries of the fixed-line communications market has further intensified.

Meanwhile, by accepting the wholesaling of fiber access services provided by NTT East and NTT West, it has become possible to provide optical-fiber broadband service ourselves from March 2015, we launched the “docomo Hikari” service (DOCOMO’s optical-fiber broadband service) and “docomo Hikari Pack,” making the first step in our journey for offering new added value through the convergence of fixed-line and mobile communications services.

Since the start of the serviceMeanwhile, underlying progress in March 2015, “docomo Hikari”Internet technology and various other technologies has enjoyed positive reviews from many customers and the total number of subscriptions exceeded 1.0 million in December 2015. Moreover, the total number of subscription applications extended 1.84 million and the total number of subscriptions to “docomo Hikari” reached 1.57 million at the end of March 2016.

In response to these changesadvanced ICT developments in thenon-communications market, environment,with the acceleration of collaboration between companies across industrial markets. By adding DOCOMO’s strengths to those of each of our partners, we have launchedpromote “+d” value co-creation initiatives aiming to deliveroffer our customers with more fun, more security and more convenience, which we call “Ever-Improving Value.” We continue to differentiate ourselves from our competitors by creating new values by making available the businessadded value

through collaboration with each of our partners using our own strengths—which include our technology, services, billing and payment platforms—and assets that we have accumulated through our operations, such as our payment platform and loyalty program to a large number of external partners. As part of this endeavor, we have rebrandedas well as the former “docomo Point” program into “d POINT” to offer a point servicecustomer bases that is highly convenient and useful for our customers withform the aim of expanding the structurecore of the “+d” activities.mobile telecommunications business.

AlthoughThrough these undertaking we aim to manage our business environment changes day-to-day and moment-to-moment, we are endeavoringtoward the goal of delivering “Ever-Improving Value” to strengthen our competitiveness based on the business strategy described below.customers.

We developed our corporate vision forestablished Medium-Term Strategy 2020^*1, “HEART: Pursuing Smart Innovation” to propel further growth and propose new values to society in anticipation of future social changes.

Also, under the banner of becoming a “Smart Life Partner” for our customers, we tackled the challenge of “reinforcing our competitiveness in telecommunications business” and “stepped up our efforts in the smart life business and other businesses. “Declaration beyond.”

Initiatives to be Implemented over the Medium Term

In orderLooking ahead to respond to our customers’ needs on an ongoing basis, by further evolving our relationships with various external partners through open collaboration, we will continue to create new added value by moving forward with our “+d” initiatives.

Specifically, we, together with our partners, will roll out initiatives in order to co-create new added value, making available to our partners our own business assets, such as “d CARD,” our payment platformthe year 2020 and “d POINT,” point program. Through these endeavors,beyond, we will aim to deliver “moreamaze and inspire beyond expectations for our customers and create new valueshand-in-hand with our partners by exceeding customers’ expectations.

The word “beyond” reflects our will to transform ourselves to realize a richer future with 5G. For our customers, we plan to offer enhanced benefits more fun and more convenience”convenience as well as value and inspiration, such as enjoyment, surprise, satisfaction and peace of mind, and realize theco-creation of new values through “+d” initiatives such as making contributions to industries, solving social issues and expanding our partners’ businesses.

“Declaration beyond” outlines six declarations we have set for these initiatives. By delivering three declarations intended for our customers and three for our partners, we will aim to steadily reinforce our revenue foundation and cash generation capability, while continuing to improve the returns to our customers and shareholders, thereby bringing about a future of abundance.

For more information regarding ourMedium-Term Strategy 2020 “Declaration beyond,” please see “D. Trend Information” in tandem with our partners.

In addition to creating value for our customers, we will also strive to offer new value to various of our partners. Particularly, in the areas of “IoT^*2,” “Regional Revitalization,” “2020,” and “Solution of Social Issues,” we will move forward with the “co-creation of social values,” creating new services and businesses in collaboration with our partners and utilizing the assets of both parties, with the goal of capturing revenue opportunities in new business fields that transcend the confines of industries or business formats.

FY2016 Priority Initiatives

Positioning FY2016 as the year in which we intend to make “a vibrant leap toward further growth” beyond income recovery, we will work concurrently on expanding our telecommunications business and reinforcing our smart life business and other businesses.

In FY2016, we expect a full-scale reexamination of handset prices and tariffs throughout the mobile industry. In light of these expected changes, we will reinforce our focus on families and strengthen our ability to propose comprehensive offerings comprising mobile phones, optical-fiber and other services. In this way, we plan to take the lead in changing the field of competition in the mobile industry.

As part of this endeavor, in March 2016 we introduced new billing plan offerings for light-usage customers, consisting of the new data package “Share Pack 5,” enabling families to share 5MB of data, and the expansion of the applicability of the “Kake-hodai Light” voice plan to lower volume data packages. In addition, starting June 2016, we will launch new offerings for long-term users consisting of two new rate options allowing customers to choose subscriptions with or without cancellation fees, increased discounts in the “Zutto DOCOMO Wari” scheme and the addition of reward points for customers renewing their subscriptions.

We will aim to secure income from telecommunications business through an ARPU increase resulting from expanded adoption of the new billing plan and on-going cost efficiency improvement efforts.

With respect to our smart life business and other businesses, we will work to grow our subscriptions by further enriching the services and content offered on our “dmarket” marketplace, such as “dTV,” “dhits” and “dmagazine.” We will also step up the “+d” initiatives that we pursue together

with our partners for new value creation by combining our finance/payment platforms, point program and other business assets that we have accumulated in our operations with those assets of our partners. We will also work to enhance the attractiveness of our “d POINT” loyalty point program by increasing the number of participating partners and accelerate the adoption of “d ACCOUNT.”Item 5.

2. Networks

We currently provide our services mainly on LTE andW-CDMA networks.

In December 2010, we launched LTE service for data communications devices. In November 2011, we expanded the service to smartphones. We continue our effortsare working to take advantage of our experiencedevelop base stations and expertiseaccelerate communication speeds, while utilizing theknow-how and technical skills we have built up as aan LTE service pioneer to build a robust network pursuing “convenience,” “peace”cope with the increased smartphone user traffic by measures such as enriching content and “safety.” We are endeavoringproviding new services.

In terms of base station development, by the end of March 2017 we had increased the number of base stations to provide a high quality communications environment offering faster speeds161,900 and broader reach in future.

To offer a more convenient network service to our customers, we have expanded the coverage of our “PREMIUM 4G*4G^*1” to 9761,421 cities across Japan asJapan.

We also improved the speed of network by using carrier aggregation^*2 using a new spectrum band of 3.5GHz from June 2016 and through other new techniques, in March 31, 2016. Meanwhile,2017 we also started offeringcommenced a communication service that offers Japan’s fastest maximum downlink speed of 300Mbps in selected areas from October 2015.682Mbps. Through these measures, we have successfully created a high-speed communication environment that provides customers with a stable and convenient network experience.

In addition,an effort to reinforce our networks, we conducted surveys of effective data speeds adhering to the “Guidelines for the Effective Speed Measurement Method of Internet Connection Services Provided by Mobile Telecommunications Carriers and Information Providing Method, etc. for Users” defined by the Ministry of Internal Affairs and Communications.MIC. The results indicated that we offerachieved improvements in both high download speeds and high upload speeds (theover the previous year. The median (Android + iOS) speed of our download speeds is 71Mbpswas 118Mbps (166% the level of the previous year), and that the median speed of our upload speeds was 23Mbps (110% the level of the previous year).

We continue to reinforce our network by using new technologies in order to offer convenient, high speed and stable communication quality to our customers.

We are also advancing research on 5G to achieve transmission speeds exceeding 10Gbps, about 1,000 times the capacity of LTE, in response to the increasing the number of communication devices and varied services that accompany the spread of IoT communication toward the planned launch of services in 2020. Since 2013, discussions regarding 5G have been advancing at international research organizations and conferences. As an enterprise that has engaged in 5G research since 2010, DOCOMO is 21Mbps).playing a leading role in global research efforts. A joint experiment on 5G was launched in 2014 in collaboration with 13 major global vendors and has steadily yielded results in verification tests. DOCOMO is leading global innovation toward realizing ever higher speeds by leveraging our network operationsknow-how and leading-edge technical development capabilities, which we have cultivated for many years.

The MIC has allocated a total bandwidth of approximately 530MHz as radio frequencies available for use forLTE/W-CDMA networks (3.5GHz, 2GHz, 1.7GHz, 1.5GHz, 900MHz, 800MHz 700MHz and 2GHzTDD)700MHz). Of this, we have been allocated 6 frequency bands—3.5GHz, 2GHz, 1.7GHz, 1.5GHz, 800MHz and 700MHz—to operate our networks.

3.5GHz Band:

With regard to our plan to open specified base stations to be used for the 3.5GHz band, approval was received from the Minister of MIC in December 2014. The 40MHz (TDD) block allocated in the 3.5GHz band has been used by ourTDD-format LTE services since June 2016.

2GHz Band:

The 20MHz x 2 allocated in the 2GHz band is jointly used by our LTE andW-CDMA networks. A maximum 20MHz x 2 is used for our LTE network.

1.7GHx Band:

The 20MHz x 2 allocated in the 1.7GHz band is jointly used by our LTE andW-CDMA networks in the Kanto, Kansai and Tokai areas. We also intend to further expand use for the LTE network in the future.

1.5GHz Band:

The 15MHz x 2 allocated in the 1.5GHz band is used by our LTE network.

800MHz Band:

The 15MHz x 2 allocated in the 800MHz band is jointly used by our LTE andW-CDMA networks. The maximum 15MHz x 2 is used for our LTE network.

700MHz Band:

With regard to our plan to open specified base stations to be used for the 700MHz band, approval was received from the Minister of MIC in June 2012. In addition, the Association of 700MHz Frequency Promotion was established by 4 operators (NTT DOCOMO, Inc., KDDI Corporation, eAccess Ltd. (currently SoftBank Corp.) and Okinawa Cellular Telephone Company) that were approved at the same

time. Together with the appropriate transfer of new frequency bands to existing licensees currently using the frequencies, receiver measures for overland digital TV broadcasts are being implemented. Since May 2015, we have been using the 10MHz x 2 allocated in the 700MHz band for LTE services.

3.5GHz Band:

With regard to our plan to open specified base stations to be used for the 3.5GHz band, approval was received from the Minister of MIC in December 2014. We intend to commence the provision of TDD-format LTE services in the 40MHz (TDD) block allocated in the 3.5GHz band from June 2016.

To provide customers with a more stable and convenient communication environment, we reinforce our network platform to respond to increases in data traffic due to smartphone use resulting from the provision of richer content and new services. For example, we expanded network capacity, mainly the ”PREMIUM 4G” which utilizes the frequency band efficiently, as we enhanced the communication network facilities.

In March 2016, we commenced the operation of a commercial network utilizing virtualization techniques. The employment of equipment using these techniques from March 2016 allowed us to offer higher quality network services to our customers. The techniques realized better connectivity in cases of network congestion and higher reliability in the event of the failure of facilities.

In addition, with the aim of reinforcing our communication capacity in densely populated areas duringwide-area disasters or power outages, we moved ahead with the conversion of large-zone base stations to make them compatible with LTE in order to increase the communication capacity by approximately three fold. Furthermore, we have rolled out medium-zone base stations across Japan to secure communications in the centers of coastal and mountainous areas.

Furthermore, in order to establish and maintain our high-quality network economically and efficiently, we provide fair competitive opportunities, foster mutual understanding and build trusting relationships with suppliers, and purchase high-quality network equipment at low cost from suppliers inside and outside Japan in accordance with our procurement policies, which emphasize compliance with CSR and various laws.

3. Products

We purchase products from vendors and then sell them mainly to mainly our sales agency whothird party distributors, which sell these products to our subscribers.

To expand our smartphone user base and to facilitate the adoption of multiple devices by a single user in order to meet the diverse needs of customers, we have strived to enrich our product lineup. In the fiscal year ended March 31, 2016,2017, we introduced 18 smartphone models, fourlaunched a total of 20 devices, which included 12 smartphones, one tablet, models, threetwo docomo Feature Phones, two Raku Raku phones (phones that are more user-friendly as compared to other smartphones and feature phones), one docomo Kids & Juniors phone models and onetwo data communication device model, and solddevices, with combined sales of approximately 26.0527.48 million units.

We have also provided our first inoriginal smartphone, the world“MONOMO-01J” which is simple and easy to release a smartphone equipped with—as well as other biometric functions, including fingerprint recognition—an iris recognition authentication system. In this way, we made effortsuse. We have also been working to offer customers simpler authentication methods than entering a password for various services that DOCOMO offers. For the 2015-2016 winter/spring collections, we launched the sales of smartphones featuring “PREMIUM 4G” and 4K-supported displays, allowing customers to enjoy photos and videos with higher resolution. In addition, we expanded the lineupenhance ourline-up of devices, to meet the diverse needs of customers, including the latest models of the popular iPhone and iPad.models.

As a result of the above, the number of smartphones and tablets sold was 15.44approximately 15.03 million units, an increase of 0.84 million units over the number sold last term, reaching approximately 60% of total sales for the fiscal year ended March 31, 2016.units.

We offer a wide range of data communication devices for selection, depending on usage, including mobileWi-Fi routers, USB data cards, and the like.

By choosing the “Pake-aeru” plan that corresponds to the estimated monthly data quantity to be used by a family or the corporate users, the service enables the division of the data usage among multiple contract lines.

The billing plan consists mainly of threefour plans for single users (2GB, 5GB, 20GB and 8GB)30GB) and foursix plans for families (10GB,(5GB, 10GB, 15GB, 20GB30GB, 50GB and 30GB)100GB).
