We have acted as U.S. counsel to the underwriters named in Schedule II to the underwriting agreement, dated as of May 16, 2023 (New York City time)/May 17, 2023 (Tokyo time) (the “Underwriting Agreement”), a copy of which is being filed as Exhibit 5.C to Amendment No. 1 to the Annual Report of Japan International Cooperation Agency (the “Issuer”) on Form 18-K/A for the fiscal year ended March 31, 2023 (the “Amendment”), relating to the offering by the Issuer of an aggregate of $1,250,000,000 principal amount of the Issuer’s 4.000% Guaranteed Bonds due May 23, 2028 (the “Bonds”), guaranteed as to payment of principal and interest by Japan (the “Guarantor”) (the “Guarantee” and, together with the Bonds, the “Securities”). The Securities are to be issued pursuant to a fiscal agency agreement, dated as of May 16, 2023 (New York City time)/May 17, 2023 (Tokyo time) (the “Fiscal Agency Agreement”, and together with the Underwriting Agreement, the “Agreements”), among the Issuer, the Guarantor, MUFG Bank, Ltd., London Branch, as the Fiscal Agent, Principal Paying Agent and Transfer Agent (the “Fiscal Agent”) and U.S. Bank Trust Company, National Association, as the U.S. Representative of the Fiscal Agent.

In connection with the opinions set forth herein, we have examined such corporate records, documents (including, without limitation, the Underwriting Agreement and Fiscal Agency Agreement), instruments, certificates of public officials and of the Issuer and the Guarantor, and have considered such questions of law as we have deemed necessary for the purpose of rendering the opinions set forth herein. We have also examined (i) the Registration Statement on Form S-B (No. 333-268943) (the “Registration Statement”) filed by the Issuer and the Guarantor relating to the Securities with the United States Securities and Exchange Commission (the “Commission”) in accordance with the provisions of the United States Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Act”), (ii) the prospectus, dated March 7, 2023 (the “Base Prospectus”), which forms a part of the Registration Statement, (iii) the preliminary prospectus supplement, dated May 11, 2023 (together with the Base Prospectus, the “Preliminary Prospectus”), (iv) the prospectus supplement, dated May 16, 2023 (together with the Base Prospectus, the “Prospectus”) and (v) the term sheet relating to the Securities filed by the Issuer with the Commission as a free writing prospectus on May 16, 2023.

In such examination, we have assumed the genuineness of all signatures and the authenticity of all items submitted to us as originals and the conformity with originals of all items submitted to us as copies. In making our examination of all documents, we have assumed that each party thereto had the power and authority to execute and deliver, and to perform and observe the provisions of, such documents, and we have also assumed the due authorization by each such party of all requisite actions and the due execution and delivery of such documents by each such party, and that (except as provided in our opinions below) such documents constitute, or will constitute upon execution and delivery thereof, the legal, valid and binding obligations of each such party.

In addition, the opinions hereinafter expressed are subject to the following qualifications and exceptions:

(i) the effect of bankruptcy, insolvency, reorganization, arrangement, moratorium or other similar laws relating to or affecting the rights of creditors generally, including, without limitation, laws relating to fraudulent transfers or conveyances, preferences and equitable subordination;

(ii) limitations imposed by general principles of equity upon the availability of equitable remedies or the enforcement of any provision of the Fiscal Agency Agreement, the Bonds and the Guarantee, and the effect of judicial decisions which have held that certain provisions are unenforceable where their enforcement would violate the implied covenant of good faith and fair dealing, or would be commercially unreasonable, or where their breach is not material; and

(iii) limitations imposed by the United States Foreign Sovereign Immunities Act of 1976.

Based upon and subject to the foregoing and other qualifications and limitations set forth herein, and assuming that the Fiscal Agency Agreement has been duly authorized, executed and delivered, we are of the opinion that:

1.    When the Bonds have been duly authorized, executed, authenticated and issued by the Issuer and sold as contemplated by the Agreements, the Bonds will constitute valid and legally binding obligations of the Issuer; and

2.    When the Guarantee has been duly authorized, executed and issued by the Guarantor as contemplated by the Agreements, the Guarantee will constitute a valid and legally binding obligation of the Guarantor.
