Mizuho Financial Group, Inc., a joint stock corporation incorporated with limited liability under the laws of Japan ("Mizuho Financial Group" or the "Issuer"), will issue an aggregate principal amount of $1,000,000,000 of senior callable fixed-to-fixed reset rate notes due May 27, 2029 (the "6-year Notes"), an aggregate principal amount of $700,000,000 of senior callable fixed-to-fixed reset rate notes due May 27, 2031 (the "8-year Notes") and an aggregate principal amount of $900,000,000 of senior callable fixed-to-fixed reset rate notes due May 27, 2034 (the "11-year Notes" and, together with the 6-year Notes and the 8-year Notes, the "Notes," or the "Fixed-to-Fixed Reset Rate Notes").

The 6-year Notes will bear interest (i) from (and including) February 27, 2023 to (but excluding) May 27, 2028 (the "6-year Notes Reset Date"), at the fixed rate of 5.667% per annum, payable semi-annually in arrears on May 27 and November 27 of each year, with the first interest payment to be made on November 27, 2023 (there will therefore be a long first coupon on the 6-year Notes), and (ii) from (and including) the 6-year Notes Reset Date to (but excluding) the maturity date, at a fixed per annum rate equal to the applicable U.S. Treasury Rate (as defined below) as determined by the Calculation Agent (as defined below) on the 6-year Notes Reset Determination Date (as defined below) as described under "Description of the Notes—Fixed-to-Fixed Reset Rate Notes—Determination of the U.S. Treasury Rate," plus 1.50%, payable semi-annually in arrears on November 27, 2028 and May 27, 2029. The 6-year Notes will mature on May 27, 2029.

The 8-year Notes will bear interest (i) from (and including) February 27, 2023 to (but excluding) May 27, 2030 (the "8-year Notes Reset Date"), at the fixed rate of 5.739% per annum, payable semi-annually in arrears on May 27 and November 27 of each year, with the first interest payment to be made on November 27, 2023 (there will therefore be a long first coupon on the 8-year Notes), and (ii) from (and including) the 8-year Notes Reset Date to (but excluding) the maturity date, at a fixed per annum rate equal to the applicable U.S. Treasury Rate as determined by the Calculation Agent on the 8-year Notes Reset Determination Date (as defined below) as described under "Description of the Notes—Fixed-to-Fixed Reset Rate Notes—Determination of the U.S. Treasury Rate," plus 1.65%, payable semi-annually in arrears on November 27, 2030 and May 27, 2031. The 8-year Notes will mature on May 27, 2031.

The 11-year Notes will bear interest (i) from (and including) February 27, 2023 to (but excluding) May 27, 2033 (the "11-year Notes Reset Date"), at the fixed rate of 5.754% per annum, payable semi-annually in arrears on May 27 and November 27 of each year, with the first interest payment to be made on November 27, 2023 (there will therefore be a long first coupon on the 11-year Notes), and (ii) from (and including) the 11-year Notes Reset Date to (but excluding) the maturity date, at a fixed per annum rate equal to the applicable U.S. Treasury Rate as determined by the Calculation Agent on the 11-year Notes Reset Determination Date (as defined below) as described under "Description of the Notes—Fixed-to-Fixed Reset Rate Notes—Determination of the U.S. Treasury Rate," plus 1.80%, payable semi-annually in arrears on November 27, 2033 and May 27, 2034. The 11-year Notes will mature on May 27, 2034.

Mizuho Financial Group may redeem, at its option, each series of the Notes, in whole, but not in part, on the date that is one year prior to the maturity date of such series of Notes, at the applicable redemption price, subject to certain conditions. See "Description of Notes—Optional Redemption." In addition, Mizuho Financial Group may at its option redeem the Notes of each series, in whole, but not in part, upon the occurrence of certain changes in Japanese tax law, subject to certain conditions. See "Description of the Notes—Optional Tax Redemption." Each series of the Notes will not be subject to any sinking fund. The Notes will be represented by one or more global notes deposited with a custodian for and registered in the name of a nominee of The Depository Trust Company ("DTC"), as depositary. Beneficial interests in the Notes will be shown on, and transfers thereof will be effected only through, records maintained by DTC and its direct and indirect participants, including Euroclear Bank SA/NV ("Euroclear"), and Clearstream Banking S.A. ("Clearstream"). The Notes will be issued only in registered form in minimum denominations of $200,000 and integral multiples of $1,000 in excess thereof.

The net proceeds from the issuance and sale of each series of the Notes will be used to make a loan to Mizuho Bank (as defined below), which intends to utilize such funds for its general corporate purposes. See "Use of Proceeds."

Each series of the Notes is intended to qualify as external total loss-absorbing capacity ("TLAC") debt under the Japanese TLAC Standard (as defined below). The Notes will be Mizuho Financial Group's direct, unconditional, unsubordinated and unsecured obligations and rank *pari passu* and without preference among themselves and with all other unsecured obligations, other than subordinated obligations of Mizuho Financial Group (except for statutorily preferred exceptions) from time to time outstanding. See also "Risk Factors—Risks Relating to the Notes—The Notes will be structurally subordinated to the liabilities of our subsidiaries, including Mizuho Bank and Mizuho Trust & Banking."

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 Luxembourg Stock Exchange's Euro MTF Market is not a regulated market for the purposes of Directive 2014/65/EU ("MiFID II") or Regulation (EU) No 600/2014 as it forms part of domestic law in the United Kingdom (as amended, "UK MiFIR"). This prospectus supplement with the accompanying prospectus constitutes the listing prospectus for purposes of Part IV of the Luxembourg law on prospectuses for securities dated July 16, 2019. This prospectus supplement and the accompanying prospectus do not constitute a prospectus for the purposes of Regulation (EU) 2017/1129 or such regulation as it forms part of domestic law in the United Kingdom by virtue of the European Union (Withdrawal) Act 2018 (as amended, the "EUWA").

**Investing in the Notes involves risks. You should carefully consider the risk factors set forth in "Item 3.D. Key Information—Risk Factors" of our most recent annual report on Form 20-F filed with the U.S. Securities and Exchange Commission (the "SEC"), and in the "[Risk Factors](#s_rom376046_6)" section beginning on page S-9 of this prospectus supplement before making any decision to invest in the Notes.**

***Japan***

The Notes have not been and will not be registered under the Financial Instruments and Exchange Act of Japan (Act No. 25 of 1948), as amended, (the "Financial Instruments and Exchange Act") and are subject to the Special Taxation Measures Act of Japan (Act No. 26 of 1957), as amended (the "Special Taxation Measures Act"). The Notes may not be offered or sold in Japan or to, or for the benefit of, any resident of Japan (which term as used in this sentence means any person resident of Japan, including any corporation or other entity organized under the laws of Japan) or to others for reoffering or resale, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the Financial Instruments and Exchange Act and any other applicable laws, regulations and governmental guidelines of Japan. See "Underwriting (Conflicts of Interest)." The Notes are not, as part of the distribution by the underwriters pursuant to the underwriting agreement dated the date hereof 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 (x) an individual resident of Japan or a Japanese corporation, nor (y) an individual non-resident of Japan or a non-Japanese corporation that in either case is a person having a special relationship with Mizuho Financial Group as described in Article 6, Paragraph 4 of the Special Taxation Measures Act (a "specially-related person of Mizuho Financial Group") or (ii) a Japanese designated financial institution, designated in Article 6, Paragraph 11 of the Special Taxation Measures Act, except as specifically permitted under the Special Taxation Measures Act. **BY SUBSCRIBING FOR THE NOTES, AN INVESTOR WILL BE DEEMED TO HAVE REPRESENTED IT IS A PERSON WHO FALLS INTO THE CATEGORY OF (i) OR (ii) ABOVE.**

Interest payments on the Notes will generally be subject to Japanese withholding tax unless it is established that such Notes are held by or for the account of a beneficial owner that is (i) for Japanese tax purposes, neither (x) an individual resident of Japan or a Japanese corporation, nor (y) an individual non-resident of Japan or a non-Japanese corporation that in either case is a specially-related person of Mizuho Financial Group, (ii) a Japanese designated financial institution described in Article 6, Paragraph 11 of the Special Taxation Measures Act which complies with the requirement for tax exemption under that paragraph or (iii) a Japanese public corporation, a Japanese financial institution or a Japanese financial instruments business operator described in Article 3-3, 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 not described in the preceding paragraph, or to an individual non-resident of Japan or a non-Japanese corporation that in either case is a specially-related person of Mizuho Financial Group will be subject to deduction in respect of Japanese income tax at a current rate of 15.315% (15% on or after January 1, 2038) of the amount of such interest.

***The European Economic Area***

**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 (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, or MiFID II as amended; or (ii) a customer within the meaning of Directive 2016/97/EU, as amended, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently, no key information document required by Regulation (EU) No 1286/2014, or the PRIIPs Regulation as amended, for offering or selling the Notes or otherwise making them available to any 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.

***United Kingdom***

**PROHIBITION OF SALES TO UK 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 United Kingdom ("UK"). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 ("EUWA"); or (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 ("FSMA") and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA. Consequently, no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the "UK PRIIPs Regulation") for offering or selling the Notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

There are restrictions on the offer and sale of the Notes in the UK. All applicable provisions of the FSMA with respect to anything done by any person in relation to the Notes in, from, or otherwise involving, the UK must be complied with. See "Underwriting (Conflicts of Interest)—Notice to Prospective Investors in the UK."

This prospectus supplement is being distributed only to and is directed only at persons located outside the UK or in the UK to (i) persons who have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the "Financial Promotion Order"); or (ii) high net worth entities falling within Article 49(2)(a) to (d) of the Financial Promotion Order; or (iii) persons to whom it may otherwise lawfully be communicated (all such persons together being referred to as "relevant persons"). This prospectus supplement must not be acted on or relied on in the UK by persons who are not relevant persons. In the UK, any investment or investment activity to which this prospectus supplement relates is only available to, and will be engaged in with, relevant persons.

**ABOUT THIS PROSPECTUS SUPPLEMENT** 

This document consists of two parts. The first part is this prospectus supplement, which describes the specific terms of the offering of the Notes and also adds to, updates and changes information contained in the prospectus filed with the SEC dated August 5, 2022, and the documents incorporated by reference in this prospectus supplement. The second part is the above-mentioned prospectus, to which we refer as the "accompanying prospectus." The accompanying prospectus contains a description of the senior and subordinated debt securities and gives more general information, some of which may not apply to the Notes. If the description of the Notes in this prospectus supplement differs from the description in the accompanying prospectus, the description in this prospectus supplement supersedes the description in the accompanying prospectus.

We have not, and the underwriters have not, authorized any other person to provide you with any information other than that contained in or incorporated by reference into this prospectus supplement, in the accompanying prospectus or in any 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 are the underwriters making, an offer to sell the Notes in any jurisdiction where the offer or sale is not permitted. You should not assume that the information appearing in this prospectus supplement, the accompanying prospectus or in any 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 its respective date. Our business, financial condition, results of operations and prospects may have changed since those respective dates.

**CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS** 

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein contain in a number of places forward-looking statements regarding our intent, belief, targets or current expectations of our management with respect to our financial condition and future results of operations. 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 the Exchange Act. In many cases, but not all, we use such words as "aim," "anticipate," "believe," "endeavor," "estimate," "expect," "intend," "may," "plan," "probability," "project," "risk," "seek," "should," "strive," "target" and similar expressions in relation to us or our management to identify forward-looking statements. You can also identify forward-looking statements by discussions of strategy, plans or intentions. These statements reflect our current views with respect to future events and are subject to risks, uncertainties and assumptions. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, our actual results may vary materially from those we currently anticipate.

We have identified some of the risks inherent in forward-looking statements in "Item 3.D. Key Information—Risk Factors" of our most recent annual report on Form 20-F and in the "Risk Factors" section of this prospectus supplement. Other factors could also adversely affect our results or the accuracy of forward-looking statements in this prospectus supplement, the accompanying prospectus or the documents incorporated by reference herein and therein, and you should not consider these to be a complete set of all potential risks or uncertainties.

The forward-looking statements included or incorporated by reference in this prospectus supplement and the accompanying prospectus are made only as of the dates on which such statements were made. We expressly disclaim any obligation or undertaking to release any update or revision to any forward-looking statement contained herein or therein to reflect any change in our expectations with regard thereto or any change in events, conditions or circumstances on which any statement is based.

**Recent Developments** 

***Information Systems Incidents***

We and our subsidiary, Mizuho Bank, received business improvement orders dated September 22, 2021 and November 26, 2021 from the Financial Services Agency (FSA) pursuant to the provisions of Article 52-33, Paragraph 1 and Article 26, Paragraph 1 of the Banking Act of Japan. In response to this, we and Mizuho Bank submitted a business improvement plan to the FSA on January 17, 2022. We have been implementing measures to prevent further incidents based on the business improvement plan and building up crisis response capability in a multidimensional manner.

Mizuho Bank received a corrective order dated November 26, 2021 from the Ministry of Finance (MOF) pursuant to the provision of Article 17-2, Paragraph 1 of the Foreign Exchange and Foreign Trade Act of Japan in connection with its failure to adequately perform the confirmation obligations mentioned in Article 17 of the said act. In response to this, Mizuho Bank submitted a report including proposed improvements and prevention measures and adjustments of the audit regime. Mizuho Bank has been implementing measures to prevent further incidents, reassessing causes for such issues and reforming the internal control structure to better comply with the Foreign Exchange and Foreign Trade Act.

By the end of December 2022, we have established systems to prevent and respond to information system incidents, have made steady progress in executing various measures (including various inspections and employee trainings) in practice, and, in the future, will endeavor to make continuous improvements under our established systems. Such systems include the implementation of preventative maintenance measures and the enhancement of our IT governance, system resources as well as response capabilities to information system failures. We will continue to dedicate ourselves to foster enhanced organizational responses and ensure the sustainable operation of our new systems.

See "Item 3.D. Key Information—Risk Factors—Problems relating to our information technology (IT) systems could significantly disrupt our business operations," and "Item 4.B. Information on the Company—Business Overview—General—Investigations into Incidents of System Failure" in our most recent annual report on Form 20-F, which is incorporated by reference in this prospectus supplement.

**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 the 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.D. Key Information—Risk Factors" of our annual report on Form 20-F for the fiscal year ended March 31, 2022, which is incorporated herein by reference.* 

**Risks Relating to Our Business** 

For information on risks relating to our business, see "Item 3.D. Key Information—Risk Factors" in our most recent annual report on Form 20-F, which is incorporated by reference in this prospectus supplement, and similar information in any other documents incorporated by reference herein.

**Risks Relating to the Notes** 

***The Notes will be structurally subordinated to the liabilities of our subsidiaries, including Mizuho Bank and Mizuho Trust & Banking.***

Your claim as a Noteholder is structurally subordinated to the liabilities of our banking and other subsidiaries, including our subsidiaries' liabilities for deposits, borrowed money, derivative transactions and trade payables. As a Noteholder, you will only be entitled to assert a claim as a creditor of Mizuho Financial Group that is to be paid out of Mizuho Financial Group's assets. If any of our subsidiaries becomes subject to insolvency or liquidation proceedings, you will have no right to proceed against such subsidiary's assets.

Mizuho Financial Group is a holding company that currently has no significant assets other than its investments in, or loans to, its subsidiaries, including Mizuho Bank and Mizuho Trust & Banking. Mizuho Financial Group's ability to service its debt obligations, including its obligations under the Notes, thus depends on the dividends, loan payments and other funds Mizuho Financial Group receives from its subsidiaries. Mizuho Financial Group may not be able to receive such funds from a subsidiary due to adverse changes in its financial performance or material deterioration in its financial condition, restrictions imposed as a result of such adverse change or deterioration by relevant laws and regulations, including banking and other regulations (such as loss absorption requirements) and limitations under general corporate law, or any contractual obligations applicable to such subsidiary. Furthermore, if a subsidiary becomes subject to insolvency or liquidation proceedings, Mizuho Financial Group's right to participate in such subsidiary's assets will be subject to the prior claims of the creditors and any preference shareholders of the subsidiary, except where Mizuho Financial Group is a creditor or preference shareholder with claims that are recognized to be ranked either ahead of or pari passu with such claims. As a result, you may not recover your investment in the Notes in full or at all even though the investors in or creditors of our subsidiaries may recover their investments in full.

Mizuho Financial Group's loans to, or investments in capital instruments issued by, its subsidiaries made or to be made with the net proceeds from the sale of its instruments may contain contractual mechanisms that, upon the occurrence of a trigger event relating to prudential or financial condition or other events applicable to Mizuho Financial Group or its subsidiaries under regulatory requirements, including the Internal TLAC (as defined

------

##### [**Table of Contents**](#toc)
below) requirements in Japan, will result in a write-down, write-off or conversion into equity of such loans or investments, or other changes in the legal or regulatory form or the ranking of the claims Mizuho Financial Group has against the subsidiaries. For example, to ensure that each of its material subsidiaries in Japan deemed systemically important by the FSA maintains the required minimum level of Internal TLAC under the Internal TLAC requirements in Japan, Mizuho Financial Group may extend to such subsidiaries, using the net proceeds from the sale of the senior debt securities and other debt instruments, subordinated loans that qualify as Internal TLAC instruments pursuant to the Internal TLAC requirements in Japan, including those containing contractual loss absorption provisions ("Contractual Loss Absorption Provisions") that will discharge or extinguish the loans or convert them into ordinary shares of the subsidiaries if the FSA determines that the relevant subsidiaries are non-viable due to material deterioration in their financial condition after recognizing that they are or are likely to be unable to fully perform their obligations with their assets, or that they have suspended, or are likely to suspend, repayment of their obligations. Any such write-down, write-off or conversion into equity, or changes in the legal or regulatory form or the ranking, or the triggering of Contractual Loss Absorption Provisions, could adversely affect Mizuho Financial Group's ability to obtain repayment of such loans and investments and to meet its obligations under the Notes as well as the value of the Notes.

***The Notes may become subject to loss absorption if Mizuho Financial Group becomes subject to orderly resolution measures under the Deposit Insurance Act of Japan and Japanese insolvency laws. As a result, the value of the Notes could be materially adversely affected, and you may lose all or a portion of your investments.***

In November 2015, the Financial Stability Board issued the final TLAC standard for global systemically important banks ("G-SIBs"), including us. The Financial Stability Board's TLAC standard is designed to ensure that, if a G-SIB fails, it has sufficient loss-absorbing and recapitalization capacity available in resolution to implement an orderly resolution that minimizes the impact on financial stability, thereby ensuring the continuity of critical functions and avoiding exposing public funds to loss. The Financial Stability Board's TLAC standard defines a minimum requirement for the instruments and liabilities that should be readily available to absorb losses in resolution. For more information regarding the Financial Stability Board's TLAC standards, see "Item 4.B. Information on the Company—Business Overview—Supervision and Regulation—Japan—Total Loss Absorbing Capacity" in our annual report on Form 20-F for the fiscal year ended March 31, 2022, which is incorporated herein by reference. The FSA published its policy describing its approach for the introduction of this standard in Japan in April 2016, and a revised version of this document was published in April 2018 (the "FSA's Approach"). In March 2019, the FSA published regulatory notices and related materials to implement the TLAC requirements in Japan. The TLAC standard set forth in these FSA documents (the "Japanese TLAC Standard"), which became applicable to (i) G-SIBs in Japan from March 31, 2019, and (ii) a financial group designated as a domestic systemically important bank in Japan by the FSA which is deemed to be in particular need of a cross-border resolution arrangement and to be of particular systemic significance to the Japanese financial system in the event of its failure (such domestic systemically important bank, together with G-SIBs in Japan, the "Covered SIBs") from March 31, 2021, and the FSB's TLAC standard requires Domestic Resolution Entities (as defined below) designated for Covered SIBs to meet certain minimum external TLAC requirements and to cause any of their material subsidiaries in Japan deemed systemically important by the FSA or their foreign subsidiaries subject to TLAC or similar requirements in the relevant jurisdictions to maintain a certain minimum level of capital and debt having internal loss-absorbing and recapitalization capacity ("Internal TLAC"). The FSA designated as resolution entities in Japan (the "Domestic Resolution Entities") the ultimate holding company in Japan of each Covered SIB. Under the Japanese TLAC Standard, the FSA designated us as the Domestic Resolution Entity for the Mizuho Group, which is subject to the external TLAC requirements in Japan, and also designated Mizuho Bank, Mizuho Trust & Banking and Mizuho Securities as our material subsidiaries in Japan, which are subject to the Internal TLAC requirements in Japan. Under the Japanese TLAC Standard, unsecured senior debt issued by the Domestic Resolution Entity for a Japanese G-SIB is not required to include any contractual write-down, write-off or conversion provisions in order to qualify as external TLAC debt. In addition, unsecured senior debt issued by the Domestic Resolution Entity for a Japanese G-SIB is not required to include any subordination provisions in order to qualify as external TLAC debt, so long as its creditors are

------

##### [**Table of Contents**](#toc)
recognized as structurally subordinated to the creditors of its subsidiaries and affiliates by the FSA on the grounds that the amount of excluded liabilities as defined in the Japanese TLAC Standard of such Domestic Resolution Entity ranking pari passu or junior to its unsecured senior liabilities does not exceed 5% of its external TLAC in principle, while the Internal TLAC incurred by material subsidiaries of a Japanese G-SIB is required to include the Contractual Loss Absorption Provisions and to be subordinated to such entity's excluded liabilities. The Notes are intended to qualify as external TLAC debt under the Japanese TLAC Standard, due in part to their structural subordination.

The Notes are expected to become subject to loss absorption if Mizuho Financial Group becomes subject to orderly resolution measures under the Deposit Insurance Act and Japanese insolvency laws. The resolution framework for financial institutions under current Japanese laws and regulations includes (i) measures applied to financial institutions that are solvent on a balance sheet basis and (ii) orderly resolution measures applied to financial institutions that have failed or are deemed likely to fail. The framework applies to banks and certain other financial institutions as well as financial holding companies, such as Mizuho Financial Group. In the Japanese TLAC Standard and the FSA's Approach, the FSA expressed its view that Single Point of Entry ("SPE") resolution, in which a single national resolution authority applies its resolution tools to the ultimate holding company in Japan of a group, would be the preferred strategy for resolution of Covered SIBs. However, it is uncertain which resolution strategy or specific measures will be taken in a given case, including whether or not the SPE resolution strategy is to be chosen and implemented in a given case, and orderly resolution measures may be applied without implementing any of the measures described in (i) above. Under a possible model of SPE resolution described in the Japanese TLAC Standard, if the FSA determines that a material subsidiary in Japan of a financial institution that is a Japanese G-SIB is non-viable due to a material deterioration in its financial condition after recognizing that it is, or is likely to be, unable to fully perform its obligations with its assets, or that it has suspended, or is likely to suspend, repayment of its obligations, and issues an order concerning restoration of financial soundness, including recapitalization and restoration of liquidity of such material subsidiary, to the Domestic Resolution Entity for the financial institution under Article 52-33, Paragraph 1 of the Banking Act of Japan (Act No. 59 of 1981, as amended), the material subsidiary's Internal TLAC instruments will be written off or, if applicable, converted into equity in accordance with the applicable Contractual Loss Absorption Provisions of such Internal TLAC instruments. Following the write-off or conversion of Internal TLAC instruments, if the Prime Minister recognizes that the financial institution is or is likely to be unable to fully perform its obligations with its assets, or that it has suspended, or is likely to suspend, repayment of its obligations, as a result of the financial institution's loans to, or other investment in, its material subsidiaries that are designated by FSA as being systemically important or that are subject to TLAC requirements or similar requirements imposed by a relevant foreign authority, becoming subject to loss absorption or otherwise, and further recognizes that the failure of such financial institution is likely to cause a significant disruption to the Japanese financial market or system, the Prime Minister may, following deliberation by the Financial Crisis Management Meeting, confirm that measures set forth in Article 126-2, Paragraph 1, Item 2 of the Deposit Insurance Act, generally referred to as specified item 2 measures (*tokutei dai nigo sochi*), need to be applied to the financial institution for its orderly resolution. Any such confirmation by the Prime Minister would also trigger the point of non-viability clauses of 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.

Under current Japanese laws and regulations, upon the application of specified item 2 measures *(tokutei dai nigo sochi)*, a financial institution will be placed under special supervision *(tokubetsu kanshi)* by, or if the Prime Minister so orders, under special control *(tokutei kanri)* of, the Deposit Insurance Corporation. In an orderly resolution, if the financial institution is placed under special control (*tokutei kanri*), pursuant to Article 126-5 of the Deposit Insurance Act, the Deposit Insurance Corporation would control the operation and management of the financial institution's business, assets and liabilities, including the potential transfer to a bridge financial institution established by the Deposit Insurance Corporation as its subsidiary, or such other financial institution as the Deposit Insurance Corporation may determine, of the financial institution's systemically important assets and liabilities, which in the case of Mizuho Financial Group would be expected to include the shares of Mizuho Bank, Mizuho Trust & Banking, Mizuho Securities and other material subsidiaries based on the Japanese TLAC

------

##### [**Table of Contents**](#toc)
Standard. Under the Japanese TLAC Standard, to facilitate that transfer, the Prime Minister may prohibit by its designation creditors of the financial institution from attaching any of our assets and claims which are to be transferred to a bridge financial institution or another financial institution pursuant to Article 126-16 of the Deposit Insurance Act. See also "Item 4. B. Information on the Company—Business Overview—Supervision and Regulation—Japan—Governmental Measures to Treat Troubled Institutions" in our annual report on Form 20-F for the fiscal year ended March 31, 2022, which is incorporated herein by reference. In addition, with respect to the Notes, given they are governed by the laws of the State of New York, the terms of the Notes will, in order to satisfy the requirements under the Japanese TLAC Standard, expressly limit the ability of the Noteholders to initiate any action to attach any of our assets, the attachment of which is so prohibited by the Prime Minister under Article 126-16 of the Deposit Insurance Act (or any successor provision thereto) 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*) need to be applied to Mizuho Financial Group. See "Description of the Debt Securities—Limitation on Actions for Attachment" in the accompanying prospectus. The value of assets subject to a prohibition of attachment may decline while such prohibition is in effect, and following such period, Noteholders 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 Deposit Insurance Corporation would also control the repayment of liabilities of the financial institution, and, ultimately, facilitate the orderly resolution of the financial institution through court-administrated insolvency proceedings. The Deposit Insurance Corporation has broad discretion in its application of these measures in accordance with the Deposit Insurance Act, Japanese insolvency laws and other relevant laws.

Under current Japanese laws and regulations, if Mizuho Financial Group becomes subject to specified item 2 measures (*tokutei dai nigo sochi*), the application of specified item 2 measures (*tokutei dai nigo sochi*) or other measures by, or any decision of, the Prime Minister, the Deposit Insurance Corporation or a Japanese court may result in your rights as a Noteholder or the value of your investment in the Notes being adversely affected. Under the Japanese TLAC Standard, it is currently expected that the Notes will not be transferred to a bridge financial institution or other transferee in the orderly resolution process but will remain as Mizuho Financial Group's liabilities subject to court-administered insolvency proceedings. On the other hand, in an orderly resolution process, the shares of Mizuho Financial Group's material subsidiaries may be transferred to a bridge financial institution or other transferee, pursuant to the authority of the Deposit Insurance Corporation to represent and manage and dispose of Mizuho Financial Group's assets under Article 126-5 of the Deposit Insurance Act, with the permission of a Japanese court in accordance with Article 126-13 of the Deposit Insurance Act, which permission may be granted by court in accordance with the Deposit Insurance Act if (i) the financial institution is under special supervision (tokubetsu kanshi) by, or under special control (tokutei kanri) of, the Deposit Insurance Corporation pursuant to the Deposit Insurance Act, and (ii) the financial institution is, or is likely to be, unable to fully perform its obligations with its assets, or the financial institution has suspended, or is likely to suspend, repayment of its obligations, and Mizuho Financial Group would only be entitled to receive consideration representing the fair values of such shares, which could be significantly less than the book values of such shares. With respect to such transfer, given the Notes are governed by the laws of the State of New York, in order to satisfy the requirements under the Japanese TLAC Standard, Noteholders expressly acknowledge, accept, consent and agree to any transfer of our assets (including shares of our subsidiaries) or liabilities, or any portions thereof, with the permission of a Japanese court in accordance with Article 126-13 of the Deposit Insurance Act (or any successor provision thereto), including any such transfer made pursuant to the authority of the Deposit Insurance Corporation to represent and manage and dispose of Mizuho Financial Group's assets under Article 126-5 of the Deposit Insurance Act (or any successor provision thereto). See "Description of the Debt Securities—Permitted Transfer of Assets or Liabilities" in the accompanying prospectus. Following such transfer, the recoverable value of Mizuho Financial Group's residual assets in court-administered insolvency proceedings may not be sufficient to fully satisfy any payment obligations that Mizuho Financial Group may have under its liabilities, including the Notes. Moreover, the Notes will not be insured or guaranteed by the Deposit Insurance Corporation or any other government agency or insurer. Accordingly, the Noteholders may lose all or a portion of their investments in the Notes in court-administered insolvency proceedings.

***The circumstances surrounding or triggering orderly resolution are unpredictable, and the Japanese TLAC Standard is subject to change.***

The application of orderly resolution under the Deposit Insurance Act is inherently unpredictable and depends on a number of factors that may be beyond Mizuho Financial Group's control. The commencement of the orderly resolution process under the Deposit Insurance Act depends on, among other things, a determination by the Prime Minister, following deliberation by the Financial Crisis Management Meeting, regarding Mizuho Financial Group's viability, or the viability of one or more of Mizuho Financial Group's subsidiaries, and the risk that their failures may cause a significant disruption to the financial market or systems in Japan. Under the Japanese TLAC Standard, it is possible that specified item 2 measures *(tokutei dai nigo sochi)* may be applied to us as a result of, among other things, absorption of losses by us on our loans to or investments in, or any other Internal TLAC of, any of our material subsidiaries or material sub-groups in Japan that are designated as systemically important by the FSA or any of our foreign subsidiaries that are subject to TLAC requirements or similar requirements imposed by a relevant foreign authority, prior to the failure of such subsidiary, pursuant to the terms of such loans, investments or other Internal TLAC or in accordance with applicable Japanese or foreign laws or regulations then in effect. However, under the Japanese TLAC Standard, the actual measures to be taken will be determined by the relevant authorities on a case-by-case basis, and, as a result, it may be difficult to predict when, if at all, Mizuho Financial Group may become subject to an orderly resolution process. Accordingly, the market value of the Notes may not necessarily be evaluated in a manner similar to other types of notes issued by non-financial institutions or by financial institutions subject to different regulatory regimes. For example, any indication that Mizuho Financial Group is approaching circumstances that could result in Mizuho Financial Group becoming subject to an orderly resolution process could also have an adverse effect on the market price and liquidity of the Notes.

In addition, there has been no application of the orderly resolution measures under the Deposit Insurance Act described in this prospectus supplement to date. Such measures are untested and will be subject to interpretation and application by the relevant authorities in Japan. It is uncertain how and under what standards the relevant authorities would determine that Mizuho Financial Group is, or is deemed likely to be unable to fully perform its obligations with its assets, or that Mizuho Financial Group has suspended, or is deemed likely to suspend, repayment of its obligations in determining whether to commence an orderly resolution process, and it is possible that particular circumstances that seem similar may lead to different results. In addition, the sequence and specific actions that will be taken in connection with orderly resolution measures and their impact on the Notes are uncertain. It is also uncertain whether a sufficient amount of assets will ultimately be available to the Noteholders. Mizuho Financial Group's creditors, including the Noteholders, may encounter difficulty in challenging the application of orderly resolution measures to Mizuho Financial Group.

Although Mizuho Financial Group expects the Notes to qualify as external TLAC due in part to their structural subordination, there is no assurance that the Notes will qualify as such, which could affect our ability to meet the minimum TLAC requirements and subject us to potential adverse regulatory action. The Japanese TLAC Standard requires each Japanese G-SIB to hold external TLAC eligible instruments in an amount not less than 18% of its risk-weighted assets and 6.75% of the applicable Basel III leverage ratio denominator from March 31, 2022, and 7.10% of the applicable Basel III leverage ratio denominator from April 1, 2024, while excluding the amounts of deposits at the Bank of Japan from the total exposure for the purpose of calculation of the applicable Basel III leverage ratio denominator, taking into account exceptional macroeconomic conditions and other circumstances. Under the Japanese TLAC Standard, Japanese G-SIB's access to Japan's deposit insurance fund reserves qualifies as TLAC in the amount equivalent to 3.5% of consolidated risk-weighted assets from March 31, 2022. As the Japanese TLAC Standard is subject to change, if such changes occur in the future, may result in us issuing debt instruments in the future with term that differ from those of the Notes, which in turn could adversely affect the value of the Notes.

***The Notes are unsecured obligations.***

The Notes are unsecured obligations, and their repayment may be compromised if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mizuho Financial Group enters into bankruptcy, liquidation, rehabilitation or other winding-up proceedings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mizuho Financial Group defaults in payment under our secured indebtedness or other unsecured indebtedness; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any of our indebtedness is accelerated.

If any of these events occurs, our assets may not be sufficient to pay amounts due on the Notes.

***The Indenture and the Notes contain very limited restrictive covenants and provide limited protection in the event of a change in control.***

The Indenture in respect of the Notes and the Notes do not contain any financial covenants or other restrictions on our ability to pledge or dispose of assets or to secure other indebtedness, pay dividends on our shares of common stock, incur indebtedness or our ability to issue new securities or repurchase our outstanding securities. These or other actions by us could adversely affect the ability of Mizuho Financial Group 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 Noteholders in the event of a change in control. See "Description of the Debt Securities—Covenants" in the accompanying prospectus.

***There is no prior market for the Notes, and the Notes may have limited liquidity.***

There is no existing market for the Notes. 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 active trading market for the Notes will develop or be sustained or whether, or at what price, Noteholders will be able to sell or otherwise transfer their Notes. The liquidity of any trading market for the Notes will depend upon the number of Noteholders, our results of operations and financial condition, the market for similar securities, the interest of securities dealers in making a market in the Notes and other factors. Although certain underwriters have informed us that they intend to make a market in the Notes, such underwriters are not obligated to do so, and any such market-making activity will be subject to the limits imposed by applicable law and may be interrupted or discontinued at any time without notice. If an active trading market for the Notes does not develop or is not sustained, the market price and liquidity of the Notes may be adversely affected and you may be unable to resell our Notes or may only be able to sell them at a substantial discount.

***The ratings on the Notes could be lowered, suspended or withdrawn, and Mizuho Financial Group's credit ratings may not reflect all risks of an investment in the Notes.***

We intend to apply for credit ratings for the Notes. Mizuho Financial Group's credit ratings may not reflect the potential impact of all risks relating to the market value of the Notes. However, real or anticipated changes in Mizuho Financial Group's credit ratings will generally affect the market value of the Notes.

In addition, other rating agencies may assign credit ratings to the Notes with or without any solicitation from us and without any provision of information from us. A rating is not a recommendation to buy, sell or hold securities and may be subject to revision, suspension or withdrawal, the assignment of new ratings that are lower than existing ratings, or a downgrade or potential downgrade in the ratings assigned to us, our subsidiaries or any of our respective securities and could reduce the scope of potential investors in the Notes and adversely affect the price and liquidity of the Notes. We have no obligation to inform Noteholders of any such downgrade, suspension, withdrawal or revision.

##### [**Table of Contents**](#toc)
***We may redeem the Notes at our option, subject to certain conditions.***

We have the option to redeem each series of the Notes in whole, but not in part, on the date that is one year prior to the maturity date of such series of Notes at 100% of their principal amount plus any accrued and unpaid interest to (but excluding) the date of redemption as described under "Description of the Notes—Optional Redemption," in addition to the option to redeem the Notes of each series in whole, but not in part, at 100% of their principal amount plus any accrued and unpaid interest to (but excluding) the date of redemption upon the occurrence of certain tax events as described under "Description of the Notes—Optional Tax Redemption." Any such redemption is subject to certain conditions, including our obtaining prior confirmation of the FSA (if and to the extent required under the then applicable Japanese banking laws or regulations), regardless of whether such redemption would be favorable or unfavorable to you.

Any decision by us as to whether we will exercise our option to redeem the Notes will be made at our absolute discretion, subject to certain conditions. Our decision may be influenced by factors such as, but not limited to, the economic impact of exercising such option to redeem the Notes, any tax consequences, the applicable TLAC and other regulatory requirements and the prevailing market conditions. We may, for example, decide to redeem the Notes prior to their maturity date if the interest payable on the Notes is greater than the interest that would be payable on our other outstanding financial instruments of a comparable maturity, of comparable terms and of a comparable credit rating.

You will not have the right to request the redemption of the Notes. As a result, you may be required to bear the financial risks of an investment in the Notes until maturity. You should not invest in the Notes with the expectation that we will exercise our option to redeem the Notes. In addition, our optional redemption of the Notes or the perception that the Notes may be redeemed in the circumstances described above may negatively affect the market value of the Notes. Moreover, if we redeem the Notes, you may not be able to reinvest the redemption proceeds in financial instruments offering a yield comparable to that on the Notes.

**Risks Relating to the Fixed-to-Fixed Reset Rate Notes** 

***The interest rate on the Notes will reset on the 6-year Notes Reset Date, the 8-year Notes Reset Date and the 11-year Notes Reset Date, as applicable.***

The interest rate on the Notes will initially be the applicable fixed per annum rate set forth on the cover page of this prospectus supplement from and including the issue date to, but excluding, the 6-year Notes Reset Date, the 8-year Notes Reset Date and the 11-year Notes Reset Date, as applicable. From and including the 6-year Notes Reset Date, the 8-year Notes Reset Date and the 11-year Notes Reset Date, as applicable, to, but excluding, the applicable maturity date, the interest rate on the Notes will be reset to a fixed per annum rate equal to the applicable U.S. Treasury Rate as determined by the Calculation Agent on the 6-year Notes Reset Determination Date, the 8-year Notes Reset Determination Date and the 11-year Notes Reset Determination Date, as applicable, as described under "Description of the Notes—Fixed-to-Fixed Reset Rate Notes—Determination of the U.S. Treasury Rate," plus the applicable spread set forth on the cover page of this prospectus supplement. As a result, the interest rate on the Notes following the 6-year Notes Reset Date, the 8-year Notes Reset Date and the 11-year Notes Reset Date, as applicable, may be less than the applicable initial interest rate, which would affect the amount of any interest payments under the Notes and, by extension, could affect their market value.

***The historical U.S. Treasury Rates are not an indication of future U.S. Treasury Rates.***

The interest rate on the Notes from and including the 6-year Notes Reset Date, the 8-year Notes Reset Date and the 11-year Notes Reset Date, as applicable, to, but excluding, the applicable maturity date will be reset to a fixed per annum rate to be determined based on the applicable U.S. Treasury Rate on the 6-year Notes Reset Determination Date, the 8-year Notes Reset Determination Date and the 11-year Notes Reset Determination Date, as applicable. In the past, U.S. Treasury Rates have experienced significant fluctuations. You should note that historical levels, fluctuations and trends of U.S. Treasury Rates are not necessarily indicative of future levels.

------

##### [**Table of Contents**](#toc)
Any historical upward or downward trend in U.S. Treasury Rates is not an indication that U.S. Treasury Rates are more or less likely to increase or decrease at any time, and you should not take the historical U.S. Treasury Rates as an indication of future rates. You bear the financial risks of fluctuations in the U.S. Treasury Rates and their effect on the interest on, and the market value of, the Notes.

**USE OF PROCEEDS** 

We estimate that we will receive net proceeds from the issuance and sale of each series of the Notes (after deducting underwriting discounts and estimated offering expenses payable by us) of approximately $2,588.0 million which we intend to use to make a loan that is intended to qualify as Internal TLAC under the Japanese TLAC Standard to Mizuho Bank. Mizuho Bank intends to utilize such funds for its general corporate purposes.

Notes:

(1) Figures have been adjusted to reflect the share consolidation in respect of our common stock on the basis of one
post-consolidation share per ten pre-consolidation shares which became effective on October 1, 2020. For purposes of the amounts per share, we have assumed the effective date of the share consolidation to
be April 1, 2017.

(2) Yen amounts are expressed in U.S. dollars at the rate of ¥106.20 = U.S. $1.00, ¥110.68 = U.S. $1.00,
¥107.53 = U.S. $1.00, ¥110.61 = U.S. $1.00 and ¥121.44 = U.S. $1.00 for the fiscal years ended March 31, 2018, 2019, 2020, 2021 and 2022, respectively, and ¥111.50 = U.S. $1.00 and ¥144.71 = U.S. $1.00 for the six months
ended September 30, 2021 and 2022, respectively. These rates are the noon buying rates on the respective fiscal year-end dates in New York City for cable transfers in yen as certified for customs purposes by
the Federal Reserve Bank of New York.

(3) Figures represent cash dividends per share with respect to the applicable fiscal year. Dividends with respect to
a fiscal year include year-end dividends and interim dividends. Declaration and payment of dividends are conducted during the immediately following fiscal year, in the case of year-end dividends, or immediately following interim period, in the case of interim dividends.

**SUPPLEMENTAL FINANCIAL AND OTHER INFORMATION (JAPANESE GAAP)** 

The table below sets forth our selected historical consolidated and other financial data under Japanese GAAP, as of and for the fiscal years ended March 31, 2018, 2019, 2020, 2021 and 2022, as of and for the six months ended September 30, 2021 and 2022 and as of and for the nine months ended December 31, 2021 and 2022.

The selected consolidated financial information as of and for the fiscal years ended March 31, 2018, 2019, 2020, 2021 and 2022 has been derived from our audited consolidated financial statements under Japanese GAAP which have been audited by Ernst & Young ShinNihon LLC, our independent auditor, and which are not included in or incorporated by reference into this prospectus supplement. The selected consolidated financial information as of and for the six months ended September 30, 2021 and 2022 and as of and for the nine months ended December 31, 2021 and 2022 is derived from our unaudited consolidated financial statements under Japanese GAAP, English-language translations of which are incorporated by reference into this prospectus supplement from our current reports on Form 6-K dated November 29, 2022 and February 14, 2023, respectively.

Some statistical information is primarily reported by Japanese banks on a non-consolidated basis and is presented as such in this prospectus supplement. Selected aggregated non-consolidated figures for the principal banking subsidiaries of the Mizuho Group are also provided for reference purposes.

Our results of operations as of and for the six months ended September 30, 2022 or as of and for the nine months ended December 31, 2022 are not necessarily indicative of our results of operations for the fiscal year ending March 31, 2023 or any future period.

Japanese GAAP differs in certain respects from U.S. GAAP. For a description of certain differences between U.S. GAAP and Japanese GAAP, see "Item 5. Operating and Financial Review and Prospects—Reconciliation with Japanese GAAP" in our most recent annual report on Form 20-F filed with the SEC, which is incorporated by reference herein.

(2) For the fiscal year ended March 31, 2022, net extraordinary gains were ¥44.0 billion (a decrease
of ¥71.8 billion from the previous fiscal year), which included gains on cancellation of employee retirement benefit trust of ¥74.2 billion (a decrease of ¥2.7 billion from the previous fiscal year). For the nine months
ended December 31, 2022, net extraordinary gains were ¥31.8 billion (a decrease of ¥25.6 billion from the same period in the prior fiscal year), which included gains on cancellation of employee retirement benefit trust of ¥41.2
billion (a decrease of ¥25.0 billion from the same period in the prior fiscal year).

(3) In billions of yen.

(4) Net gains (losses) related to ETFs and others was ¥1.9 billion for the fiscal year ended March 31,
2022 (a decrease of ¥0.1 billion from the previous fiscal year) and ¥5.5 billion for the nine months ended December 31, 2022 (an increase of ¥1.8 billion from the same period in the previous fiscal year).

(5) Figures in parentheses show negative credit-related costs as a result of gains on reversal of reserves for
possible losses on loans, and others.

(6) Credit-related costs consist of (a) expenses related to portfolio problems (including reversal of
(provision for) general reserve for losses on loans), (b) gains on reversal of reserves for possible losses on loans, and others, and (c) credit costs for trust accounts. For the fiscal year ended March 31, 2021, credit-related costs of
¥204.9 billion included ¥132.6 billion of credit-related costs and ¥72.3 billion of reserves recorded from a forward-looking perspective. For the fiscal year ended March 31, 2022, credit-related costs of ¥235.1 billion
included ¥207.5 billion of credit-related costs and ¥27.6 billion of reserves recorded from a forward-looking perspective. For the nine months ended December 31, 2022, credit-related costs of ¥65.3 billion included ¥51.5 billion of
credit-related costs and ¥13.7 billion of reserves recorded from a forward-looking perspective. As of March 31, 2021, March 31, 2022 and December 31, 2022, we had a balance of reserves recorded from a forward-looking perspective of ¥111.5
billion, ¥81.7 billion and ¥56.0 billion, respectively (period-end balance).

(7) Net gains (losses) related to stocks—net gains (losses) related to ETFs and others was ¥(45.7) billion
for the fiscal year ended March 31, 2022 (a decrease of ¥55.8 billion from the previous fiscal year) and a gain of ¥41.9 billion for the nine months ended December 31, 2022 (an increase of ¥75.5 billion from the same period in
the previous fiscal year).

(8) Bills discounted refer to a form of financing in Japan under which promissory notes obtained by corporations
through their regular business activities are purchased by banks prior to their payment dates at a discount based on prevailing interest rates.

(9) Includes ¥15.6 trillion of Japanese government bonds (a decrease of ¥10.0 trillion from the end of the
previous fiscal year), ¥10.8 trillion of foreign bonds (an increase of ¥0.9 trillion from the end of the previous fiscal year) and ¥3.0 trillion of Japanese stocks (a decrease of ¥0.2 trillion from the end of the previous fiscal
year) as of December 31, 2022.

(10) Includes negotiable certificates of deposit.

(11) Risk-adjusted capital data are calculated on a Basel III basis from the fiscal year ended March 31, 2013.
We adopted the advanced internal ratings-based approach for the calculation of risk-weighted assets associated with credit risk from the fiscal year ended March 31, 2009. We also adopted the advanced measurement approach for the calculation of
operational risk from the fiscal year ended March 31, 2010. For more details on capital adequacy requirements set by the Bank for International Settlements, and the guideline implemented by the FSA in compliance thereto, see "Item 5.
Operating and Financial Review and Prospects—Capital Adequacy" in our annual report on Form 20-F for the fiscal year ended March 31, 2022, which is incorporated by reference herein.

(12) Excluding net unrealized gains (losses) on other securities and its associated deferred gains (losses) on hedges
from the numerator. Deducts risk weighted assets associated with net unrealized gains (losses) on other securities (Japanese stocks) from the denominator. Includes the effect of partially fixing unrealized gains on stocks through hedging
transactions.

(13) On a fully-effective basis under the Basel III finalization framework expected to be fully applied in 2029.

(14) Excluding net unrealized gains (losses) on other securities and its associated deferred gains (losses) on hedges
from the numerator. Deducts risk weighted assets associated with net unrealized gains (losses) on other securities (Japanese stocks) from the denominator. Includes the effect of partially fixing unrealized gains on stocks through hedging
transactions. The capital floor is also calculated after deducting the associated reserves from risk weighted assets using the standard approach.

(15) Due to the amendment to the leverage ratio regulations and TLAC regulations introduced as a temporary measure by
the FSA, the amount of deposits to the Bank of Japan was excluded from total exposure since March 31, 2021. Accordingly, such amounts, as well as leverage and external TLAC ratios on a total exposure basis, are not directly comparable to prior
years.

(16) Calculated after deduction of capital buffer requirement.

(17) Calculated before deduction of capital buffer requirement.

(18) For the three months ended March 31, 2019, 2020, 2021 and 2022, September 30, 2021 and 2022 and December
31, 2021 and 2022, respectively. Consolidated liquidity coverage ratio is calculated as the three-month average of the daily liquidity coverage ratio for the relevant three months, which is calculated by dividing the balance of total high-quality
liquid assets by the amount of net cash outflows on a daily basis for the same three months.

(19) For the three months ended March 31, 2019, 2020, 2021 and 2022, September 30, 2021 and 2022 and December
31, 2021 and 2022, respectively.

(20) Total disclosed claims and NPL ratios as of December 31, 2021 or before are based on the FRA, and total
disclosed claims and NPL ratios as of March 31, 2022 or after are based on the Banking Act and the FRA.

(21) NPL ratio = total disclosed claims under the FRA / total claims. Includes banking account and trust account.

(22) Other securities which have readily determinable fair values. Excluding investments in partnership. Figures are
on an acquisition cost basis.

(23) Other securities which have readily determinable fair values. Excluding investments in partnership. Changes in
value to be recorded directly to net assets after tax and other necessary adjustments. Japanese stocks on March 31, 2020 were calculated based on the average market price of the month. Other items were calculated based on the quoted market
price if available, or other reasonable value, at the end of the month.

***Russian-related Exposure***

As of December 31, 2022, our direct net country exposure to Russia was $2.11 billion on an aggregate basis of Mizuho Bank (consolidated) and Mizuho Trust & Banking (consolidated), which primarily consisted of outstanding loans, commitment lines, guarantee transactions and derivatives-related credit, etc.

Considering the country risk arising from the sanctions against Russia and the downgrading of their credit rating, as well as the risk of deterioration in the global economy due to inflation caused by soaring energy prices and the acceleration of supply chain disruptions caused by the withdrawal of operations from Russia, we incorporated an estimate of the Russia-Ukraine situation into the macroeconomic scenario used for determining the allowance for credit losses on loans and recorded reserves, including reserves from a forward-looking perspective.

As of December 31, 2022, Mizuho Bank (consolidated) and Mizuho Trust & Banking (consolidated), on an aggregated basis, had reserves with Russian-related exposure (direct effect) of ¥105.3 billion (including reserve account for possible losses on loans to restructuring countries).

**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 referred to herein or therein.* 

**General** 

Each series of the Notes will constitute a series of senior debt securities to be issued under a senior indenture between us and The Bank of New York Mellon, as trustee, dated as of September 13, 2016, as amended or supplemented from time to time (the "Indenture"). The Indenture is qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. 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 corporate trust office of the trustee.

The Notes will constitute direct, unconditional, unsubordinated and unsecured obligations of Mizuho Financial Group and rank *pari passu* and without preference among themselves and with all other unsecured obligations, other than subordinated obligations, of Mizuho Financial Group (except for statutorily preferred exceptions) from time to time outstanding.

Mizuho Financial Group is a holding company and conducts substantially all of its operations through its subsidiaries. As a result, claims of noteholders will be structurally subordinated to claims of creditors of its subsidiaries. In addition, various statutes and regulations, including banking and other regulations, may restrict Mizuho Financial Group's subsidiaries from paying dividends or principal of or interest on loans or other funds to Mizuho Financial Group. See "Risk Factors— Risks Relating to the Notes—The Notes will be structurally subordinated to the liabilities of our subsidiaries, including Mizuho Bank and Mizuho Trust & Banking."

The Notes will be repaid at maturity at a price of 100% of the principal amount thereof. Each series of the Notes may be redeemed on the date that is one year prior to the maturity date of such series of Notes, as described under "—Optional Redemption," and the Notes of each series may be redeemed at any time prior to maturity in the circumstances described under "—Optional Tax Redemption." The Notes will be issued in denominations of $200,000 or integral multiples of $1,000 in excess thereof. The Notes do not provide for any sinking fund.

Payments on the Notes will be made in accordance with any laws, regulations or administrative practices applicable to Mizuho Financial Group and its agents in respect thereof, including the requirements under Japanese tax law.

If and to the extent Mizuho Financial Group shall default in the payment of interest when due, such defaulted interest shall be paid to the person in whose name the relevant Note is registered at the close of business on a subsequent record date, which shall not be less than five Business Days (as defined below) prior to the payment of such defaulted interest, established by notice given by mail or in accordance with clearing system procedures by or on behalf of Mizuho Financial Group to the holder of the relevant Note not less than fifteen days preceding such subsequent record date.

The term "Business Day" means a day which is not a day on which banking institutions in New York or Tokyo are authorized by law or regulation to close.

**Fixed-to-Fixed Reset Rate Notes** 

The 6-year Notes will be initially limited to $1,000,000,000 aggregate principal amount and, unless previously redeemed or otherwise cancelled, will mature on May 27, 2029. During the 6-year Notes Initial Fixed Rate Period (as defined below), the 6-year Notes will bear interest at the fixed rate of 5.667% per annum, payable semi-annually in arrears on May 27 and November 27 of each year, commencing November 27, 2023, to the holders of record as at 5:00 p.m. (New York City time) on the day five Business Days immediately preceding such interest payment date. There will therefore be a long first coupon on the 6-year Notes. During the 6-year Notes Reset Fixed Rate Period (as defined below), the 6-year Notes will bear interest at a fixed per annum rate equal to the applicable U.S. Treasury Rate (as defined below) as determined by the Calculation Agent (as defined below) on the 6-year Notes Reset Determination Date (as defined below), plus 1.50% (the "6-year Notes Reset Fixed Rate"), payable semi-annually in arrears on November 27, 2028 and May 27, 2029 to the holders of record as at 5:00 p.m. (New York City time) on the day five Business Days immediately preceding such interest payment date (each such interest payment date, a "6-year Notes Reset Rate Interest Payment Date"). The "6-year Notes Initial Fixed Rate Period" is from, and including, February 27, 2023 to, but excluding, May 27, 2028 (the "6-year Notes Reset Date") and the "6-year Notes Reset Fixed Rate Period" is from, and including, the 6-year Notes Reset Date to, but excluding, May 27, 2029.

The 8-year Notes will be initially limited to $700,000,000 aggregate principal amount and, unless previously redeemed or otherwise cancelled, will mature on May 27, 2031. During the 8-year Notes Initial Fixed Rate Period (as defined below), the 8-year Notes will bear interest at the fixed rate of 5.739% per annum, payable semi-annually in arrears on May 27 and November 27 of each year, commencing November 27, 2023, to the holders of record as at 5:00 p.m. (New York City time) on the day five Business Days immediately preceding such interest payment date. There will therefore be a long first coupon on the 8-year Notes. During the 8-year Notes Reset Fixed Rate Period (as defined below), the 8-year Notes will bear interest at a fixed per annum rate equal to the applicable U.S. Treasury Rate as determined by the Calculation Agent on the 8-year Notes Reset Determination Date (as defined below), plus 1.65% (the "8-year Notes Reset Fixed Rate"), payable semi-annually in arrears on November 27, 2030 and May 27, 2031 to the holders of record as at 5:00 p.m. (New York City time) on the day five Business Days immediately preceding such interest payment date (each such interest payment date, a "8-year Notes Reset Rate Interest Payment Date"). The "8-year Notes Initial Fixed Rate Period" is from, and including, February 27, 2023 to, but excluding, May 27, 2030 (the "8-year Notes Reset Date") and the "8-year Notes Reset Fixed Rate Period" is from, and including, the 8-year Notes Reset Date to, but excluding, May 27, 2031. For more information on the calculation of interest during the 8-year Notes Reset Fixed Rate Period, see "—Reset Fixed Rate Period" and "—Determination of the U.S. Treasury Rate" below.

There will therefore be a long first coupon on the 11-year Notes. During the 11-year Notes Reset Fixed Rate Period (as defined below), the 11-year Notes will bear interest at a fixed per annum rate equal to the applicable U.S. Treasury Rate as determined by the Calculation Agent on the 11-year Notes Reset Determination Date (as defined below), plus 1.80% (the "11-year Notes Reset Fixed Rate"), payable semi-annually in arrears on November 27, 2033 and May 27, 2034 to the holders of record as at 5:00 p.m. (New York City time) on the day five Business Days immediately preceding such interest payment date (each such interest payment date, a "11-year Notes Reset Rate Interest Payment Date"). The "11-year Notes Initial Fixed Rate Period" is from, and including, February 27, 2023 to, but excluding, May 27, 2033 (the "11-year Notes Reset Date") and the "11-year Notes Reset Fixed Rate Period" is from, and including, the 11-year Notes Reset Date to, but excluding, May 27, 2034.

##### [**Table of Contents**](#toc)
If any payment is due on the Notes on a day that is not a Business Day, such payment will be made on the date that is the next succeeding Business Day. Payments postponed to the next succeeding Business Day in this situation will be treated under the Indenture as if they were made on the original due date. Postponement of this kind will not result in a default under the Notes or the Indenture, and no interest will accrue on the postponed amount from the original due date to the next succeeding Business Day. Interest on the Notes will be computed on the basis of a 360-day year consisting of twelve 30-day months and rounding the resulting figure to the nearest cent (half a cent being rounded upwards).

*Initial Fixed Rate Period* 

The Notes will bear interest at the relevant fixed rate per annum set forth on the cover page of this prospectus supplement and under "The Offering—Interest" and "—Fixed-to-Fixed Reset Rate Notes" above during the 6-year Notes Initial Fixed Rate Period, the 8-year Notes Initial Fixed Rate Period and the 11-year Notes Initial Fixed Rate Period, as applicable.

*Reset Fixed Rate Period* 

The interest rate for the 6-year Notes will be reset to the 6-year Notes Reset Fixed Rate on the 6-year Notes Reset Date, and the 6-year Notes will bear the 6-year Notes Reset Fixed Rate during the 6-year Notes Reset Fixed Rate Period.

The interest rate for the 8-year Notes will be reset to the 8-year Notes Reset Fixed Rate on the 8-year Notes Reset Date, and the 8-year Notes will bear the 8-year Notes Reset Fixed Rate during the 8-year Notes Reset Fixed Rate Period.

The interest rate for the 11-year Notes will be reset to the 11-year Notes Reset Fixed Rate on the 11-year Notes Reset Date, and the 11-year Notes will bear the 11-year Notes Reset Fixed Rate during the 11-year Notes Reset Fixed Rate Period.

*Determination of the U.S. Treasury Rate* 

The U.S. Treasury Rate shall be determined by The Bank of New York Mellon as calculation agent (as used in the terms of the Notes, in such capacity together with any successor, the "Calculation Agent").

"U.S. Treasury Rate" means, with respect to the 6-year Notes Reset Fixed Rate Period, the 8-year Notes Reset Fixed Rate Period and the 11-year Notes Reset Fixed Rate Period, as applicable, the rate per annum equal to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the arithmetic average, as determined by the Calculation Agent, of the yields on actively traded U.S. Treasury
securities adjusted to constant maturity for the maturity of one year ("Yields") for the five consecutive New York Business Days (as defined below) immediately prior to the 6-year Notes Reset Determination Date, the 8-year Notes Reset Determination Date or the 11-year Notes Reset Determination Date, as applicable, based on information appearing in the statistical release designated
"H.15" (or any successor publication that reports Yields) most recently published by the Board of Governors of the U.S. Federal Reserve System as of 5:00 p.m. (New York City time) on the 6-year Notes
Reset Determination Date, the 8-year Notes Reset Determination Date or the 11-year Notes Reset Determination Date, as applicable; provided that if the Yield is not available through such release (or any
successor publication) for any relevant New York Business Day, then the arithmetic average will be determined based on the Yields for the remaining New York Business Days during the five New York Business Day period described above (provided further
that if the Yield is available for only a single New York Business Day during such five New York Business Day period, then "U.S. Treasury Rate" will mean the single-day Yield for such day); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) if no information is available to determine the U.S. Treasury Rate in accordance with the method set forth in

"Reference Treasury Dealer Quotation" means, with respect to each Reference Treasury Dealer, the arithmetic average, as determined by the Calculation Agent, of the bid and asked prices quoted to Mizuho Financial Group or its Designee (and notified to the Calculation Agent) by such Reference Treasury Dealer for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, approximately at 11:00 a.m. (New York City time), on the 6-year Notes Reset Determination Date, the 8-year Notes Reset Determination Date or the 11-year Notes Reset Determination Date, as applicable.

The Calculation Agent will, as soon as practicable after the determination of the 6-year Notes Reset Fixed Rate, the 8-year Notes Reset Fixed Rate and the 11-year Notes Reset Fixed Rate, as applicable, calculate the amount of interest (the "Interest Amount") payable for the 6-year Notes Reset Fixed Rate Period, the 8-year Notes Reset Fixed Rate Period or the 11-year Notes Reset Fixed Rate Period, as applicable, with respect to the 6-year Notes, the 8-year Notes or the 11-year Notes, as applicable.

In addition, notwithstanding anything to the contrary in this prospectus supplement, the accompanying prospectus, the Indenture or the relevant Notes, Mizuho Financial Group may designate as its Designee an entity, which may be Mizuho Financial Group's affiliate, to make any determination, decision or election that Mizuho Financial Group has the right to make for the purposes of calculating the 6-year Notes Reset Fixed Rate, the 8-year Notes Reset Fixed Rate and the 11-year Notes Reset Fixed Rate, as applicable, and the Interest Amount.

All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one thousandth of a percentage point, with five ten-thousands of a percentage point rounded upwards (*e.g.*, 9.8765% (or .098765) being rounded to 9.877% (or .09877)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (half a cent being rounded upwards).

The 6-year Notes Reset Fixed Rate, the 8-year Notes Reset Fixed Rate and the 11-year Notes Reset Fixed Rate, as applicable, on such series of Notes during the 6-year Notes Reset Fixed Rate Period, the 8-year Notes Reset Fixed Rate Period and the 11-year Notes Reset Fixed Rate Period, as applicable, will in no event be higher than the maximum rate permitted by applicable laws and regulations or lower than 0% per annum.

Mizuho Financial Group has the right to remove the Calculation Agent at any time, which removal will take effect on the date of the appointment by Mizuho Financial Group of a successor Calculation Agent.

**Optional Redemption** 

Mizuho Financial Group may redeem, at its option, each series of the Notes in whole, but not in part, on the date that is one year prior to the maturity date of such series of Notes, subject to the prior confirmation of the FSA (if and to the extent required under the then applicable Japanese banking laws or regulations), at a redemption price equal to the sum of 100% of the principal amount of the relevant series of Notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date and "additional amounts" (as described in the accompanying prospectus), if any.

If the date that is one year prior to the maturity date of a series of Notes to be redeemed would otherwise fall on a day that is not a Business Day, payment of the redemption price will be made on the day that is the next succeeding Business Day. Payments postponed to the next Business Day in this situation will be treated under the Indenture as if they were made on the original due date. Postponement of this kind will not result in a default under the series of Notes to be redeemed.

If Mizuho Financial Group elects to redeem any series of the Notes, it will provide notice at least 15 days and not more than 60 days before the date fixed for redemption. Each notice of redemption will state:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• such election of Mizuho Financial Group to redeem the Notes of such series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the redemption date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the redemption price;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the principal amount and CUSIP or ISIN number and/or common code of the Notes to be redeemed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• that on the redemption date the redemption price will become due and payable upon each Note to be redeemed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• that interest thereon will cease to accrue on and after the redemption date; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the place or places where the Notes to be redeemed are to be surrendered for payment of the redemption price and
that (in the event such series of Notes are in certificated form) such series of Notes designated in such notice for redemption are required to be presented on or after such redemption date at the designated place or places of payment.

Notwithstanding the foregoing, if the Notes to be redeemed are held in book-entry form through DTC, Mizuho Financial Group may give such notice in any manner permitted or required by DTC. See "Description of the Debt Securities—Book-Entry; Delivery and Form—DTC's Procedures for Notices, Voting and Payments" in the accompanying prospectus.

**Optional Tax Redemption** 

Each series of the Notes may be redeemed at the option of Mizuho Financial Group, in whole, but not in part, at any time, upon not less than 30 nor more than 60 days' prior notice, subject to the prior confirmation of the FSA (if and to the extent required under the then applicable Japanese banking laws or regulations), at a redemption price equal to 100% of the principal amount of the relevant series of Notes then outstanding (plus accrued and unpaid interest to (but excluding) the date fixed for redemption and "additional amounts" (as described in the accompanying prospectus), if any), if Mizuho Financial Group is, or on the next interest payment date would be, required to pay any additional amounts with respect to such series as described under "Description of the Debt Securities—Payment of Additional Amounts" in the accompanying prospectus and such obligation arises as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of Japan (or any political subdivision or taxing authority in or of Japan) affecting taxation, or any change in the official position regarding the application or interpretation of such laws, regulations or rulings (including a holding, judgment, or order by a court of competent jurisdiction), which change, amendment, application or interpretation becomes effective on or after the date of this prospectus supplement, and which obligation cannot be avoided by measures reasonably available to Mizuho Financial

Group; *provided* that, no such notice of redemption may be given earlier than 90 days prior to the earliest date on which Mizuho Financial Group would be obligated to make such payment of additional amounts if a payment in respect of the relevant series of Notes were then due. Prior to the mailing to holders of the relevant series of Notes of any notice of redemption of the relevant series of Notes pursuant to the foregoing, the Indenture requires that Mizuho Financial Group certifies to the trustee that the requirements for redemption have been met and delivers therewith to the trustee an opinion of independent tax counsel or tax consultant of recognized standing, which opinion shall be reasonably satisfactory to the trustee, to the effect that such circumstances exist. The trustee shall accept such certificate and opinion as sufficient evidence of the satisfaction of the conditions precedent described above, in which event it shall be conclusive and binding on the holders of the relevant series of Notes.

Additional amounts are payable by Mizuho Financial Group under the circumstances described under "Description of the Debt Securities—Payment of Additional Amounts" in the accompanying prospectus.

**Repurchases** 

Mizuho Financial Group or any of its subsidiaries may, at any time, subject to the prior confirmation of the FSA (if and to the extent required under the then applicable Japanese banking laws or regulations), purchase any or all of the Notes in the open market or otherwise at any price. Subject to applicable law, neither Mizuho Financial Group nor any of its subsidiaries shall have any obligation to purchase or offer to purchase any Notes held by any holder as a result of its purchase or offer to purchase Notes held by any other holder, whether on the open market or otherwise. Any such Notes purchased by Mizuho Financial Group or any of its subsidiaries may, at the discretion of Mizuho Financial Group or the relevant subsidiary, be held, resold or surrendered to the paying agent for cancellation by Mizuho Financial Group or any such subsidiary, as the case may be. The Notes so purchased, while held by or on behalf of Mizuho Financial Group or any such subsidiary, as the case may be, shall not entitle the holder to vote at any meetings of the holders of the relevant series of Notes and shall not be deemed to be outstanding for the purposes of calculating quorums at meetings of the holders of such series of Notes or for the purposes of "Description of the Debt Securities—Acceleration Upon an Event of Default" in the accompanying prospectus.

**Trustee, Paying Agent, Registrar, Transfer Agent and Calculation Agent** 

The Bank of New York Mellon, 240 Greenwich Street, New York, New York 10286, U.S.A., will initially act as trustee, paying agent, registrar, calculation agent and transfer agent with respect to the Notes. Mizuho Financial Group may change the paying agent, registrar, transfer agent or calculation agent without prior notice to the holders of the Notes (but with prior notice to the trustee), and Mizuho Financial Group or any of its subsidiaries may act as paying agent, registrar, transfer agent or calculation agent.

**Clearance and Settlement** 

The Notes have been accepted for clearance through DTC for the accounts of its participants, including Euroclear and Clearstream.

**TAXATION** 

*The following summaries are not intended as a complete analysis of the tax consequences under Japanese or United States law of the acquisition, ownership and sale of the Notes by investors. Potential investors should consult their own tax advisors on the tax consequences of acquisition, ownership, sale, and other relevant circumstances concerning the Notes, including specifically the applicable tax consequences under Japanese or United States laws, the law of the jurisdiction of their country of residence (if relevant) and any tax treaty between Japan and their country of residence.* 

**Japanese Taxation** 

*The following is a general description of certain Japanese tax aspects of the Notes and 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 advisors in order to ascertain their particular circumstances regarding taxation.* 

*The statements below are based on current tax laws and regulations in Japan and current tax treaties executed by Japan all as in effect on the date hereof 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 of so-called "taxable linked notes" as described in Article 6, Paragraph 4 of the Special Taxation Measures Act, i.e., notes of which the amount of interest is to be calculated by reference to certain indexes (as prescribed by the Cabinet Order (as defined below) under the Special Taxation Measures Act) relating to Mizuho Financial Group or a specially-related person of Mizuho Financial Group (as defined below).

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

Gains derived from the sale of Notes outside Japan by an individual non-resident of Japan or a non-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.

**Representation by Investor upon Initial Distribution of Notes** 

BY SUBSCRIBING FOR THE NOTES, AN INVESTOR WILL BE DEEMED TO HAVE REPRESENTED IT IS A PERSON WHO FALLS INTO THE CATEGORY OF (i) OR (ii) BELOW. The Notes are not, as part of the distribution by the underwriters pursuant to the underwriting agreement dated the date hereof at any time, to be directly or indirectly offered or sold to, or for the benefit of, any person other than a

------

##### [**Table of Contents**](#toc)
beneficial owner that is (i) for Japanese tax purposes, neither (x) an individual resident of Japan or a Japanese corporation, nor (y) an individual non-resident of Japan or a non-Japanese corporation that in either case is a specially-related person of Mizuho Financial Group or (ii) a Designated Financial Institution (as defined below), except as specifically permitted under the Special Taxation Measures Act.

**Interest and Redemption Gain or Redemption Loss on Notes** 

The following description of Japanese taxation (limited to national taxes) applies exclusively to interest on the Notes and the redemption gain or the redemption loss, meaning any positive or negative difference between the holder's acquisition price of the Notes and the amount which the holder receives upon redemption of such Notes, (the "Redemption Gain" or the "Redemption Loss," as the case may be), where such Notes are issued by Mizuho Financial Group outside Japan and payable outside Japan. In addition, the following description assumes that only global notes are issued for the Notes, and no definitive bonds 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 the Notes is an individual non-resident of Japan or a non-Japanese corporation for Japanese tax purposes, as described below, the Japanese tax consequences for such individual non-resident of Japan or non-Japanese corporation are significantly different depending upon whether such individual non-resident of Japan or non-Japanese corporation is a specially-related person of Mizuho Financial Group. Most importantly, if such individual non-resident of Japan or non-Japanese corporation is a specially-related person of Mizuho Financial Group, income tax at the rate of 15.315% of the amount of such interest will be withheld by Mizuho Financial Group under Japanese tax law.

**1.1** **Interest** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) If the recipient of interest on the Notes is an individual non-resident of Japan or a non-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 individual non-resident of Japan or non-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:* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) if the relevant Notes are held through a participant in an international clearing organization such as DTC or a
financial intermediary prescribed by the Special Taxation Measures Act and the relevant cabinet order thereunder (the "Cabinet Order," together with the Special Taxation Measures Act and the ministerial ordinance and other regulations
thereunder, the "Act") (each, 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 Act to enable the
Participant to establish that the recipient is exempt from Japanese tax to be withheld or deducted (the "Interest Recipient Information"), and advise the Participant if such individual non-resident of Japan or non-Japanese corporation ceases to be so exempted (including the case where it became a specially-related person of Mizuho Financial Group), and that Mizuho Financial Group prepare and file a
certain confirmation prescribed by the Act (an "Interest Recipient Confirmation") with the competent local tax office in a timely manner based upon the Interest Recipient Information communicated through the Participant and the relevant
international clearing organization; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) if the relevant Notes are not held by a Participant, the requirement that such recipient submit to the relevant
paying agent a written application for tax exemption *(Hikazei Tekiyo Shinkokusho)* (the

------

##### [**Table of Contents**](#toc)
"Written Application for Tax Exemption"), together with certain documentary evidence, and that Mizuho Financial Group 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 Act) will result in the withholding by Mizuho Financial Group of income tax at the rate of 15.315% of the amount of such interest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) If the recipient of interest on the Notes is an individual non-resident of Japan or a non-Japanese corporation having a permanent establishment within Japan and the receipt of interest is attributable to the business of such individual non-resident of Japan or non-Japanese corporation carried on within Japan through such permanent establishment, such interest will not be subject to a 15.315%
withholding tax by Mizuho Financial Group, 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 Mizuho Financial Group 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Notwithstanding Paragraphs 1.1(1) and (2) above, if an individual non-resident of Japan or a non-Japanese corporation mentioned above is a person who has a special relationship with Mizuho Financial Group (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, Mizuho Financial Group) 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 Mizuho Financial Group") as of the beginning of the fiscal year of Mizuho Financial Group 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 Mizuho Financial Group. If such individual non-resident of Japan or non-Japanese corporation has a permanent establishment within Japan, regular income tax or corporate tax, as appropriate, collected otherwise than by way of withholding, could apply to such interest under Japanese
tax law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) If an individual non-resident of Japan or a non-Japanese corporation (regardless of whether it is a specially-related person of Mizuho Financial Group) 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 individual non-resident of
Japan or non-Japanese corporation. As of the date of this document, Japan has income tax treaties, conventions or agreements whereby the above-mentioned withholding tax rate is reduced, generally to 10% with,
inter alia, Australia, Canada, Finland, France, Hong Kong, Ireland, Italy, Luxembourg, the Netherlands, New Zealand, Norway, Portugal and Singapore. Under the tax treaties between Japan and Austria, Belgium, Denmark, Germany, Spain, Sweden,
Switzerland, the United Kingdom or the United States, interest paid to qualified Austrian, Belgian, Danish, German, Spanish, Swedish, Swiss, United Kingdom or United States residents is generally exempt from Japanese withholding tax (for Belgium,
only for a Belgian enterprise). Under the current income tax treaties between Japan and Australia, France, the Netherlands or New Zealand, certain limited categories of qualified Australian, French, Dutch or New Zealand residents receiving interest
on the Notes may, subject to compliance with certain procedural requirements under Japanese law, be fully exempt from Japanese withholding tax for interest on the Notes (*provided that* no exemption will apply to pension funds in the case of
Australia and New Zealand). In order to avail themselves of such reduced rate of, or exemption from, Japanese withholding tax under any applicable income tax treaty, individual non-residents of Japan or non-Japanese corporations which are entitled, under any applicable income tax treaty, to a reduced rate

------

##### [**Table of Contents**](#toc)
of, or exemption from, Japanese withholding tax on payment of interest by Mizuho Financial Group 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) through Mizuho Financial Group to the relevant tax authority before payment of interest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Under the Act, (a) if an individual non-resident of Japan or a non-Japanese corporation that is a beneficial owner of the Notes becomes a specially-related person of Mizuho Financial Group, or an individual non-resident of Japan or a non-Japanese corporation that is a specially-related person of Mizuho Financial Group becomes a beneficial owner of the Notes, and (b) if such Notes are held through a Participant, then such individual non-resident of Japan or non-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 individual non-resident of Japan or non-Japanese corporation as a specially-related person of Mizuho Financial
Group for Japanese withholding tax purposes is determined based on the status as of the beginning of the fiscal year of Mizuho Financial Group in which the relevant interest payment date falls, such individual non-resident of Japan or non-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 individual non-resident of Japan or non-Japanese corporation as being a specially-related person of Mizuho
Financial Group.

**1.2** **Redemption Gain or Redemption Loss** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) If the recipient of the Redemption Gain is an individual non-resident of Japan or a non-Japanese corporation having no permanent establishment within Japan or having a permanent establishment within Japan but where the receipt of such Redemption Gain is not attributable to the
business of such individual non-resident of Japan or non-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. If there is any Redemption Loss, such Redemption Loss will be disregarded for purposes of regular income tax or corporate tax, as appropriate, of the recipient.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) If the recipient of the Redemption Gain is an individual non-resident of Japan or a non-Japanese corporation having a permanent establishment within Japan and the receipt of such Redemption Gain is attributable to the business of such individual non-resident of Japan or non-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. If there is any Redemption Loss, such Redemption Loss may be taken into account in computing the net taxable income, if any, for purposes of regular income
tax or corporate tax, as appropriate, of the recipient.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Notwithstanding Paragraphs 1.2(1) and (2) above, if an individual non-resident of Japan or a non-Japanese corporation mentioned above is a specially-related person of Mizuho Financial Group as of the beginning of the fiscal year of
Mizuho Financial Group in which such individual non-resident of Japan or non-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 individual non-resident of Japan or non-Japanese corporation has a permanent establishment within Japan; *provided that* exemption may be available under the relevant income tax treaty. If there is any Redemption Loss, such Redemption Loss
may be taken into account in computing the net taxable income, if any, for purposes of regular income tax or corporate tax, as appropriate, of the recipient.

------

##### [**Table of Contents**](#toc)
**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 Mizuho Financial Group, 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 (as defined below) which complies with the requirement for tax exemption under Article 6, Paragraph 11 of the Special Taxation Measures Act or (ii) a Public Corporation (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 Article 3-3, 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 their regular income tax or corporate tax consequences otherwise than by way of withholding, bearing in mind, including the treatment of the Redemption Loss especially for individual residents of Japan, the change to the taxation regime of Notes that took effect on January 1, 2016.

**2.1** **Interest** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) If an individual resident of Japan or a Japanese corporation (other than a Specified Financial Institution (as
defined below) or a Public Corporation (as defined below), who complies with the requirement as referred to in Paragraph 2.1(2) below) receives payments of interest on the Notes through certain Japanese payment handling agents as defined in Article 2-2 Paragraph 2 of the Cabinet Order (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 Mizuho Financial Group. As Mizuho Financial Group is not in a position to know in advance the recipient's status, the recipient of interest falling within this category should inform Mizuho Financial Group through a paying agent
of its status in a timely manner. Failure to so inform may result in double withholding.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 *(kokyohojin tou)* (a "Public Corporation") 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 Article 3-3, 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 (the "Japanese Custodian") and such recipient submits through such Japanese Custodian to the competent tax authority
the report prescribed by the Act, no withholding tax is levied on such interest. However, since Mizuho Financial Group is not in a position to know in advance the recipient's tax exemption status, the recipient of interest falling within this
category should inform Mizuho Financial Group through a paying agent of its status in a timely manner. Failure to so notify Mizuho Financial Group may result in the withholding by Mizuho Financial Group of a 15.315% income tax.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) If an individual resident of Japan or a Japanese corporation (except for a Designated Financial Institution (as
defined below) which complies with the requirements described in Paragraph 2.1(4) below) receives interest on the Notes not through a Japanese Payment Handling Agent, income tax at the rate of 15.315% of the amount of such interest will be withheld
by Mizuho Financial Group.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) If 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 Cabinet Order under Article 6, Paragraph 11 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 Great East Japan 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 Great East Japan Earthquake, 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 will also be certain special additional tax imposed upon regular income tax due other than by way of withholding for individual non-residents of Japan, as referred to in the foregoing descriptions, for the period mentioned above.

**United States Taxation** 

The following is a summary of certain U.S. federal income tax consequences, as of the date of this prospectus supplement, of the purchase, ownership and disposition of the Notes by a U.S. holder (as defined below). This summary deals only with Notes held as capital assets by persons who purchase the Notes upon original issuance at their initial offering price.

As used herein, a "U.S. holder" means a beneficial owner of the Notes that is for U.S. federal income tax purposes any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an individual citizen or resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or
organized in or under the laws of the United States, any state thereof or the District of Columbia;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a trust if it (1) is subject to the primary supervision of a court within the United States and one or more
United States persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a United States person.

This summary does not represent a detailed description of the U.S. federal income tax consequences applicable to you if you are subject to special treatment under the U.S. federal income tax laws, including if you are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a dealer or broker in securities or currencies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a financial institution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a regulated investment company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a real estate investment trust;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a tax-exempt entity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an insurance company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a person holding the Notes as part of a hedging, integrated or conversion transaction or a straddle;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a trader in securities that has elected the mark-to-market method of accounting for your securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a person liable for alternative minimum tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a person holding the Notes in connection with the conduct of a trade or business in Japan;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a person required to accelerate the recognition of any item of gross income with respect to the Notes for U.S.
federal income tax purposes as a result of such income being recognized on an applicable financial statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a partnership or other pass-through entity for U.S. federal income tax purposes (or an investor in such an
entity); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a U.S. holder whose "functional currency" is not the U.S. dollar.

The discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended (the "Code"), and regulations, rulings, judicial decisions and the income tax treaty between the United States and Japan (the "Treaty"), in each case as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those discussed below.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds Notes, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner of a partnership for U.S. federal income tax purposes that holds Notes, you should consult your tax advisors.

This summary does not represent a detailed description of the U.S. federal income tax consequences to you in light of your particular circumstances and does not address the Medicare tax on net investment income, U.S. federal estate and gift taxes or the effects of any state, local or non-U.S. tax laws. It is not intended to be, and should not be construed to be, legal or tax advice to any particular purchaser of Notes. **If you are considering the purchase of Notes, you should consult your own tax advisors concerning the particular U.S. federal income tax consequences to you of the purchase, ownership and disposition of the Notes, as well as the consequences to you arising under other U.S. federal tax laws and the laws of any other taxing jurisdiction.**

Notwithstanding the possibility that the Notes may become subject to loss absorption as described above, we intend to take the position (to the extent that we are required to take a position) that the Notes will be treated as indebtedness for U.S. federal income tax purposes, and the balance of this summary assumes that the Notes will be treated as indebtedness for U.S. federal income tax purposes.

***Interest***

Interest on the Notes (which includes any Japanese tax withheld and any additional amounts paid with respect thereto) generally will be taxable to you as ordinary income at the time it is received or accrued, depending on your method of accounting for U.S. federal income tax purposes.

Subject to certain conditions and limitations (including a minimum holding period requirement) and the Foreign Tax Credit Regulations (as defined below), any Japanese withholding taxes on interest may be treated as foreign taxes eligible for credit against your U.S. federal income tax liability. For purposes of calculating the foreign tax credit, interest income (including any additional amounts) on a Note will be treated as income from sources outside the United States and will generally constitute passive category income. However, recently issued Treasury regulations (the "Foreign Tax Credit Regulations") impose additional requirements for foreign taxes to be eligible for a foreign tax credit, and there can be no assurance that those requirements will be satisfied. In addition, any Japanese withholding taxes on interest will not be eligible for a foreign tax credit to the extent that the taxes are refundable under Japanese law or the Treaty or could have been eliminated by providing the Interest Recipient Information or Written Application for Tax Exemption described above in "Japanese Taxation." As discussed above in "Japanese Taxation," interest payments on the Notes are currently eligible for an exemption from Japanese withholding tax under the Treaty; therefore, if you are eligible for the benefits of the Treaty, you generally will not be entitled to a foreign tax credit for any Japanese tax withheld. Instead of claiming a foreign tax credit, you may be able to deduct any otherwise creditable Japanese withholding taxes on

------

##### [**Table of Contents**](#toc)
interest in computing your taxable income, subject to generally applicable limitations under U.S. law (including that a U.S. holder is not eligible for a deduction for any otherwise creditable foreign income taxes paid or accrued in a taxable year if such U.S. holder claims a foreign tax credit for any foreign income taxes paid or accrued in the same taxable year). The rules governing the foreign tax credit and deductions for foreign taxes are complex. You are urged to consult your tax advisors regarding the Foreign Tax Credit Regulations and the availability of the foreign tax credit or a deduction under your particular circumstances.

***Sale, Exchange or Other Taxable Disposition of Notes***

Upon the sale, exchange or other taxable disposition (including a retirement or redemption) of a Note, you generally will recognize gain or loss equal to the difference between the amount realized upon the sale, exchange or other taxable disposition (less an amount equal to any accrued and unpaid interest, which will be taxable as interest income for U.S. federal income tax purposes to the extent not previously included in income) and the tax basis of the Note. Your tax basis in a Note will, in general, be your cost for that Note. Any gain or loss generally will be capital gain or loss and generally will be long-term capital gain or loss if you have held the Note for more than one year. Long-term capital gains of non-corporate U.S. holders (including individuals) are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Any gain or loss you recognize upon the sale, exchange or other taxable disposition of a Note will generally be treated as United States source gain or loss for purposes of computing your foreign tax credit limitations.

***Information Reporting and Backup Withholding***

In general, information reporting requirements will apply to payments of interest on the Notes and to the proceeds of the sale or other disposition (including a retirement or redemption) of a Note paid to you (unless, in each case, you establish that you are an exempt recipient). Backup withholding may apply to such payments if you fail to provide a taxpayer identification number and a certification that you are not subject to backup withholding or if you fail to report in full dividend and interest income.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against your U.S. federal income tax liability provided the required information is timely furnished to the Internal Revenue Service (the "IRS").

***Foreign Financial Asset Reporting***

Certain U.S. holders are required to report information relating to an interest in the Notes, subject to certain exceptions (including an exception for Notes held in accounts maintained by certain financial institutions), by attaching a complete IRS Form 8938, Statement of Specified Foreign Financial Assets, with their tax return for each year in which they hold an interest in the Notes. You are urged to consult your own tax advisors regarding information reporting requirements relating to your ownership of the Notes.

**CERTAIN ERISA CONSIDERATIONS** 

The following is a summary of certain considerations associated with the purchase and holding of the Notes by (i) "employee benefit plans" within the meaning of the U.S. Employee Retirement Income Security Act of 1974, as amended ("ERISA"), that are subject to Title I of ERISA, (ii) plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the U.S. Internal Revenue Code of 1986, as amended (the "Code"), or provisions under any other U.S. or non-U.S. federal, state, local or other laws or regulations that are similar to such provisions of ERISA or the Code (collectively, "Similar Laws") and (iii) entities whose underlying assets are considered to include the assets of any of the foregoing described in clauses (i) and (ii) (each of the foregoing described in clauses (i) through (iii), we refer to as a "Plan"), and on those persons who are fiduciaries with respect to Plans.

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (collectively, we refer to these Plans as "Covered Plans"), including the requirement of investment prudence and diversification and the requirement that a Covered Plan's investments be made in accordance with the documents governing the Covered Plan. The prudence of a particular investment must be determined by the responsible fiduciary of a Covered Plan by taking into account the Covered Plan's particular circumstances and all of the facts and circumstances of the investment including, but not limited to, the matters discussed above under "Risk Factors" and the fact that in the future there may be no market in which such fiduciary will be able to sell or otherwise dispose of the Notes.

Section 406 of ERISA and Section 4975 of the Code prohibit certain transactions involving the assets of a Covered Plan and certain persons (referred to as "parties in interest" under ERISA and "disqualified persons" under Section 4975 of the Code) having certain relationships to such Covered Plans unless a statutory or administrative exemption is applicable to the transaction. A party in interest or disqualified person who engaged in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and/or Section 4975 of the Code. In addition, a fiduciary of the Covered Plan who engaged in such non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and/or the Code.

Prohibited transactions within the meaning of Section 406 of ERISA or Section 4975 of the Code may arise if the Notes are acquired or held with the assets of a Covered Plan with respect to which the Issuer, an underwriter or any of their respective affiliates (collectively, the "Transaction Parties") is a party in interest or disqualified person. As a result of its business, the Issuer, as well as other Transaction Parties, may be parties in interest or disqualified persons with respect to many Covered Plans. Certain exemptions from the prohibited transaction provisions of Section 406 of ERISA and Section 4975 of the Code may be applicable, however, to the acquisition or holding of the Notes depending in part on the type of Covered Plan fiduciary making the decision to acquire or hold the Notes and the circumstances under which such decision is made. Included among these exemptions are Prohibited Transaction Class Exemption ("PTCE") 91-38 (relating to investments by bank collective investment funds), PTCE 84-14 (relating to transactions effected by a "qualified professional asset manager"), PTCE 90-1 (relating to investments by insurance company pooled separate accounts), PTCE 95-60 (relating to investments by insurance company general accounts), and PTCE 96-23 (relating to transactions effected by in-house asset managers). In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide a limited exemption for the purchase and sale of securities and related lending transactions, *provided that* none of the issuer of the securities nor any of its affiliates (directly or indirectly) have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any Covered Plan involved in the transaction, and provided further that the Covered Plan pays no more, and receives no less, than "adequate consideration" (within the meaning of Section 408(b)(17) of ERISA and Section 4975(f)(10) of the Code) in connection with the transaction (the so-called "service provider exemption"). Each of the above-noted exemptions contains conditions and limitations on its application. Fiduciaries of Covered Plans considering acquiring and/or holding any Notes in reliance on these or any other exemption should carefully review the exemption in consultation with its legal advisors to assure it is applicable. There can be no assurance that any of these exemptions or any other administrative or statutory exemption will be available with respect to any particular transaction involving the Notes.

------

##### [**Table of Contents**](#toc)
Any insurance company proposing to invest assets of its general account in the Notes should consider the extent to which such investment would be subject to the requirements of Title I of ERISA or Section 4975 of the Code in light of the U.S. Supreme Court's decision in John Hancock Mutual Life Insurance Co. v. Harris Trust and Savings Bank, 510 U.S. 86 (1993) and Section 401(c) of ERISA and the regulations thereunder. Such an insurance company should consider (i) the exemptive relief granted by the U.S. Department of Labor for transactions involving insurance company general accounts in PTCE 95-60 and (ii) if such exemptive relief is not available, whether its acquisition or holding of any Notes or any interest therein will not require an exemption because the assets used for such acquisition are not subject to Title I of ERISA or Section 4975 of the Code.

Plans which are, and entities whose underlying assets constitute the assets of, governmental plans (within the meaning of Section 3(32) of ERISA), certain church plans (within the meaning of Section 3(33) of ERISA) and non-U.S. Plans (as described in Section 4(b)(4) of ERISA) may not be subject to the fiduciary responsibility or prohibited transaction provisions of Title I of ERISA or Section 4975 of the Code, but may nevertheless be subject to Similar Laws. Fiduciaries of any such plans or entities considering an investment in the Notes should consult with its legal advisors to consider the applicable fiduciary standards and to determine the potential consequences of an investment in the Notes under any applicable Similar Laws before deciding whether to acquire or hold any Notes.

By its acquisition of any Notes (or any interest therein), each purchaser and subsequent transferee thereof will be deemed to have represented and warranted, on each day from the date on which such purchaser or transferee, as applicable, acquires or holds the Notes (or any interest therein) through and including the date on which such purchaser or transferee, as applicable, disposes of the Notes (or any interest therein), either that (a) it is not acquiring or holding the Notes (or any interest therein) with the assets of a Plan or (b) its acquisition, holding and disposition of the Notes (or any interest therein) will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a violation under any applicable Similar Law.

The foregoing discussion is general in nature and is not intended to be all inclusive, and neither this discussion nor anything in this prospectus supplement is, or is intended to be, investment advice directed at potential Plan purchasers generally or any particular potential Plan purchaser, and such purchasers should consult and rely on their own counsel and advisors as to whether an investment in the Notes is suitable for the Plan. 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 or holding the Notes on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability 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, and any subsequent disposition, of the Notes.

Each purchaser and holder of an interest in the Notes will have exclusive responsibility for ensuring that its purchase and holding of the Notes does not violate the applicable fiduciary responsibility and prohibited transaction rules of ERISA and the Code or the provisions of any applicable Similar Law. Nothing in this prospectus supplement is, or should be construed as, a representation or advice as to whether an investment in the Notes would meet any or all of the relevant legal requirements with respect to investments by, or is appropriate for, Plans generally or any particular Plan. The sale of Notes to any Plan is in no respect a representation by any Transaction Party that such an investment meets all relevant legal requirement with respect to investments by Plans generally or any particular Plan, or that such investment is prudent or appropriate for Plans generally or any particular Plan.

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 the non-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.

------

##### [**Table of Contents**](#toc)
**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 0.350% of the principal amount of the 6-year Notes, a fee of 0.400% of the principal amount of the 8-year Notes and a fee of 0.450% of the principal amount of the 11-year Notes.

The estimated expenses, not including the underwriting commissions, in connection with the offer and sale of the Notes payable by us include the following:

---

| | |
|:---|:---|
|  Securities and Exchange Commission registration fee | $286520.0 |
|  Legal fees and expenses | 562000.0 |
|  Accounting fees and expenses | 118000.0 |
|  Trustee, registrar and paying agent fees and expenses | 18000.0 |
|  Miscellaneous | 130000.0 |
|  Total | $1114520.0 |

---

We have agreed to reimburse the underwriters for certain legal expenses in connection with this offering. The underwriters have agreed to reimburse us for certain documentation-related expenses incurred in connection with this offering.

**New Issue of the Notes** 

The Notes are a new issue of securities with no established 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 the Notes to be admitted to trading on the Luxembourg Stock Exchange's Euro MTF Market, we may be entitled to, and may decide to, delist the Notes from the Luxembourg Stock Exchange and seek an alternate listing for the Notes on another securities exchange. Certain underwriters have advised us that they presently intend to make a market in the Notes after completion of this offering. Mizuho Securities USA LLC may use this prospectus supplement and the accompanying prospectus in connection with such market-making activity. 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. We cannot assure the liquidity of the trading market for the Notes. A liquid or active public trading market for any of the Notes may not develop, whether on the Luxembourg Stock Exchange's Euro MTF Market or otherwise. 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 prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors. See "Risk Factors—Risks Relating to the Notes—There is no prior market for the Notes, and the Notes may have limited liquidity."

**Settlement** 

We expect that delivery of the Notes will be made to investors on or about February 27, 2023, which will be the fourth New York business day following the date of this prospectus supplement (such settlement being referred to as "T+4"). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes prior to the delivery of the Notes hereunder may be required, by virtue of the fact that the Notes initially settle in T+4, to specify an alternate settlement arrangement at the time of any such

------

##### [**Table of Contents**](#toc)
trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes prior to their date of delivery hereunder should consult their advisors.

**No Sales of Similar Securities** 

During the period commencing on the date hereof and ending the closing date of this offering, we have agreed that we will not, without first obtaining the prior written consent from the representatives of the underwriters, directly or indirectly, issue, sell, offer or agree to sell, grant any option for the sale of, or otherwise transfer or dispose of, any other U.S. dollar-denominated senior debt securities of ours, except for the Notes sold to the underwriters pursuant to the underwriting agreement.

**Price Stabilization and Short Positions** 

In addition, the underwriters may impose a penalty bid. A penalty bid is an arrangement that permits the underwriters 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 price 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. However, there is no assurance that the underwriters and/or any person acting on behalf thereof will undertake any stabilization action. Any stabilization action may begin at any time, on or after the date on which adequate public disclosure of the terms of the offer of the Notes is made and, if begun, may be ended or discontinued at any time, but it must end no later than the earlier of 30 days after the Notes are issued and 60 days after the date of the allotment of the Notes. Any stabilization action will be conducted in accordance with the law.

**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, 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), assets, 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, which, for the avoidance of doubt, includes Mizuho Financial Group or its subsidiaries and affiliates. 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

------

##### [**Table of Contents**](#toc)
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, assets, currencies or commodities.

**Conflicts of Interest** 

Mizuho Securities USA LLC 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. Mizuho Securities USA LLC will not confirm sales to accounts over which it exercises discretionary authority without the prior specific written approval of its customer.

**Selling Restrictions in Japan** 

The Notes have not been and will not be registered under the Financial Instruments and Exchange Act and are subject to the Special Taxation Measures Act. Each of the underwriters has represented and agreed that (i) it has not, directly or indirectly, offered or sold and will not, directly or indirectly, offer or sell, any Notes in Japan or to, or for the benefit of, any person resident in Japan for Japanese securities law purposes (including any corporation or other entity organized under the laws of Japan) or to others for reoffering or resale, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the Financial Instruments and Exchange Act and any other applicable laws, regulations and government guidelines of Japan; and (ii) it has not, directly or indirectly, offered or sold and will not, as part of its distribution by the underwriters pursuant to the underwriting agreement dated the date hereof at any time, directly or indirectly offer or sell any Notes to, or for the benefit of, any person other than a beneficial owner that is (a) for Japanese tax purposes, neither (x) an individual resident of Japan or a Japanese corporation, nor (y) an individual non-resident of Japan or a non-Japanese corporation that in either case is a person having a special relationship with Mizuho Financial Group as described in Article 6, Paragraph 4 of the Special Taxation Measures Act or (b) a Japanese financial institution, designated in Article 6, Paragraph 11 of the Special Taxation Measures Act. Notwithstanding the restriction set forth in (ii) above, pursuant to the Special Taxation Measures Act, Mizuho Securities USA LLC, a specially-related person of Mizuho Financial Group and acting in its capacity as an underwriter, will be permitted to acquire or purchase, as part of the distribution of the Notes, the remainder of the Notes from any of the other underwriters, where such other underwriter has failed to sell to subsequent purchasers all of the Notes that it acquired or purchased from us in its capacity as an underwriter.

**Notice to Prospective Investors in Canada** 

The Notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 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.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement (including any amendment thereto) contains a

------

##### [**Table of Contents**](#toc)
misrepresentation, *provided that* the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser's province or territory. 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.

Pursuant to section 3A.3 (or, in the case of securities issued or guaranteed by the government of a non-Canadian jurisdiction, section 3A.4) of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

**Prohibition of Sales to EEA Retail Investors** 

The Notes which are the subject of the offering contemplated by this document, as supplemented by any applicable supplement or pricing term sheet in relation thereto, may not be offered, sold or otherwise made available and will not be offered, sold or otherwise made available to any retail investor in the European Economic Area, or EEA. For the purposes of this provision, the expression "retail investor" means a person who is one (or more) of the following: (a) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended, or MiFID II; or (b) a customer within the meaning of Directive 2016/97/EU, as amended, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently, no key information document required by the PRIIPs Regulation for offering or selling the Notes or otherwise making them available to any 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. This prospectus supplement has been prepared on the basis that any offer of the Notes in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Regulation (Regulation (EU) 2017/1129), or the Prospectus Regulation, from the requirement to publish a prospectus for offers of the Notes. This prospectus supplement is not a prospectus for the purposes of the Prospectus Regulation.

**Prohibition of Sales to UK 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 UK. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the EUWA; or (ii) a customer within the meaning of the provisions of the FSMA and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA. Consequently, no key information document required by the UK PRIIPs Regulation for offering or selling the Notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

**Notice to Prospective Investors in the UK** 

Any invitation or inducement to engage in investment activity (within the meaning of Section 21 of the FSMA) in connection with the issue or sale of any Notes has only been communicated or caused to be communicated and will only be communicated or caused to be communicated in circumstances in which Section 21(1) of the FSMA does not apply to us, and all applicable provisions of the FSMA have been complied with and will be complied with in respect to anything done in relation to the Notes in, from or otherwise involving the UK.

**EXPERTS** 

The consolidated financial statements of Mizuho Financial Group, Inc. appearing in the annual report of Mizuho Financial Group, Inc. on Form 20-F for the fiscal year ended March 31, 2022, and the effectiveness of the internal control over financial reporting of Mizuho Financial Group, Inc. as of March 31, 2022, have been audited by Ernst & Young ShinNihon LLC, independent registered public accounting firm, as set forth in their reports thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.

With respect to the unaudited interim consolidated financial statements of Mizuho Financial Group, Inc. for the six-month periods ended September 30, 2022 and 2021, included in the current report of Mizuho Financial Group, Inc. on Form 6-K submitted to the SEC on December 28, 2022, and incorporated by reference in this prospectus supplement, Ernst & Young ShinNihon LLC reported that they have applied limited procedures in accordance with professional standards for a review of such financial statements. However, their separate report dated December 28, 2022, included in the current report of Mizuho Financial Group, Inc. on Form 6-K submitted to the SEC on December 28, 2022, and incorporated by reference herein, states that they did not audit and they do not express an opinion on the interim consolidated financial statements.

Accordingly, the degree of reliance on their report on such financial statements should be restricted in light of the limited nature of the review procedures applied. Ernst & Young ShinNihon LLC is not subject to the liability provisions of Section 11 of the Securities Act for their report on the unaudited interim consolidated financial statements because that report is not a "report" or a "part" of the Registration Statement prepared or certified by Ernst & Young ShinNihon LLC within the meaning of Sections 7 and 11 of the Securities Act.

Ernst & Young ShinNihon LLC's address is 1-1-2 Yurakucho, Chiyoda-ku, Tokyo 100-0006, Japan.

**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" in this prospectus before purchasing any of our debt 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.

**CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS** 

This prospectus and the financial statements and other documents incorporated by reference in this prospectus contain in a number of places forward-looking statements regarding the intent, belief, current expectations and targets of our management with respect to our financial condition and future results of operations. These statements constitute "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act").

You can also identify forward-looking statements by discussions of strategy, plans or intentions. These statements reflect our current views with respect to future events and are subject to risks, uncertainties and assumptions. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, our actual results may vary materially from those we currently anticipate.

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.

**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 will be filed as exhibits to a current report on Form 6-K in connection with an offering of the relevant series of debt securities. You should refer to those documents for additional information.* 

**General** 

We may issue senior debt securities from time to time, in one or more series under a senior indenture between us and The Bank of New York Mellon, which we refer to as the senior trustee, dated as of September 13, 2016, as amended or supplemented from time to time. We may issue subordinated debt securities from time to time, in one or more series under a subordinated indenture between us and The Bank of New York Mellon, which we refer to as the subordinated trustee, dated as of September 13, 2021, as amended or supplemented from time to time, or, if applicable, under a new subordinated indenture to be entered into between us and 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 provide or, if applicable, 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 limits or, if applicable, will limit the amount of debt securities that we may issue thereunder, nor contains or, if applicable, will 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 direct, unconditional, unsubordinated and unsecured obligations of Mizuho Financial Group and rank *pari passu* and without preference among themselves and with all other unsecured obligations, other than subordinated obligations, of Mizuho Financial Group (except for statutorily preferred exceptions) from time to time outstanding.

The subordinated debt securities of each series will constitute direct, subordinated and unsecured obligations of Mizuho Financial Group and rank *pari passu* and without preference among themselves. 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 or free writing prospectus relating to such series of subordinated debt securities.

**Further Issuances** 

Mizuho Financial Group reserves the right, from time to time, without the consent of the holders of the debt securities of a particular series, to issue additional debt securities on terms and conditions identical to those of a series offered by this prospectus and the applicable prospectus supplement, which additional debt securities shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the debt securities of such series; *provided however* that Mizuho Financial Group shall not issue any further debt securities with the same CUSIP, ISIN or other identifying number as that series of debt securities unless such further debt securities will be treated as fungible with that series of debt securities for U.S. federal income tax purposes. Mizuho Financial Group may also, without the consent of the holders of the outstanding debt securities, issue other debt securities under the indentures as part of a separate series that have different terms from the debt securities offered hereby.

**Payment of Additional Amounts** 

All payments of principal and interest in respect of the debt securities by Mizuho Financial Group shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments, levies or governmental charges of whatever nature imposed or levied by or on behalf of Japan, or any political subdivision of, or any authority in, or of, Japan having power to tax ("Japanese taxes"), unless such withholding or deduction is required by law. In that event, Mizuho Financial Group shall pay to the holder of each debt security such additional amounts (all such amounts being referred to herein as "additional amounts") as may be necessary so that the net amounts received by it after such withholding or deduction shall equal the respective amounts which would have been receivable in respect of such debt security in the absence of such withholding or deduction.

However, no such additional amounts shall be payable in relation to any such withholding or deduction in respect of any payment on a debt security:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) to or on behalf of a holder or beneficial owner of a debt security who is an individual non-resident of Japan or a non-Japanese corporation and is liable for such Japanese taxes in respect of such debt security by reason of its (a) having some connection
with Japan other than the mere holding of such

##### [**Table of Contents**](#toc)
debt security, or (b) being a person having a special relationship with Mizuho Financial Group (a "specially-related person of Mizuho Financial Group") as described in Article 6, Paragraph 4 of the Special Taxation Measures Act of Japan (Act No. 26 of 1957, as amended; the "Special Taxation Measures Act");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) to or on behalf of a holder or beneficial owner of a debt security (a) who would be exempt from any such
withholding or deduction but who fails to comply with any applicable requirement to provide certification, information, documents or other evidence concerning its nationality, residence, identity or connection with Japan, including any requirement
to provide interest recipient information (as defined below) or to submit a written application for tax exemption (as defined below) to Mizuho Financial Group or a paying agent, as appropriate, or (b) whose interest recipient information is not
duly communicated through the participant (as defined below) and the relevant international clearing organization to a paying agent;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) to or on behalf of a holder or beneficial owner of a debt security who is for Japanese tax purposes treated as
an individual resident of Japan or a Japanese corporation (except for (A) a designated financial institution (as defined below) who complies with the requirement to provide interest recipient information or to submit a written application for
tax exemption and (B) an individual resident of Japan or a Japanese corporation who duly notifies (directly or through the participant or otherwise) a paying agent of its status as not being subject to Japanese taxes to be withheld or deducted
by Mizuho Financial Group, by reason of such individual resident of Japan or Japanese corporation receiving interest on the relevant debt security through a payment handling agent in Japan appointed by it);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) to or on behalf of a holder or beneficial owner of a debt security who presents a debt security for payment
(where presentation is required) more than 30 days after the relevant date (as defined below), except to the extent that such holder or beneficial owner of a debt security would have been entitled to such additional amounts on presenting the same on
any date during such 30-day period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) to or on behalf of a holder who is a fiduciary or partnership or is not the sole beneficial owner of the
payment of the principal of, or any interest on, any 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, who would not have been entitled to such additional amounts had it been the holder of such debt security; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) in any case that is a combination of any of (i) through (v) above.

Where a debt security is held through a participant of a clearing organization or a financial intermediary (each, a "participant"), in order to receive payments free of withholding or deduction by Mizuho Financial Group for, or on account of, Japanese taxes, if the relevant beneficial owner of a debt security is (i) an individual non-resident of Japan or a non-Japanese corporation that in either case is not a specially-related person of Mizuho Financial Group or (ii) a Japanese financial institution (a "designated financial institution") falling under certain categories prescribed by Article 6, Paragraph 11 of the Special Taxation Measures Act and the cabinet order thereunder (together with the ministerial ordinance and other regulations thereunder, the "Act"), all in accordance with the Act, such beneficial owner of a debt security must, at the time of entrusting a participant with the custody of the relevant debt security, provide certain information prescribed by the Act to enable the participant to establish that such beneficial owner of a debt security is exempted from the requirement for Japanese taxes to be withheld or deducted (the "interest recipient information") and advise the participant if such beneficial owner of a debt security ceases to be so exempted, including the case where the relevant beneficial owner of the debt security who is an individual non-resident of Japan or a non-Japanese corporation becomes a specially-related person of Mizuho Financial Group.

Where a debt security is not held by a participant, in order to receive payments free of withholding or deduction by Mizuho Financial Group for, or on account of, Japanese taxes, if the relevant beneficial owner of a debt security is (i) an individual non-resident of Japan or a non-Japanese corporation that in either case is not a

------

##### [**Table of Contents**](#toc)
specially-related person of Mizuho Financial Group or (ii) a designated financial institution, all in accordance with the Act, such beneficial owner of a debt security must, prior to each date on which it receives interest, submit to Mizuho Financial Group or a paying agent, as appropriate, a written application for tax exemption (*hikazei tekiyo shinkokusho*) (a "written application for tax exemption") in the form obtainable from Mizuho Financial Group or any paying agent, as appropriate, stating, among other things, the name and address (and, if applicable, the Japanese individual or corporation ID number) of such beneficial owner of a debt security, the title of the debt securities, the relevant interest payment date, the amount of interest payable and the fact that such beneficial owner of a debt security is qualified to submit the written application for tax exemption, together with documentary evidence regarding its identity and residence.

As used in this section, the "relevant date" means the date on which any payment in respect of a debt security first becomes due, except that, if the full amount of the moneys payable has not been duly received by the paying agent on or prior to such due date, it means the date on which, the full amount of such moneys having been so received, notice to that effect is duly given to the holders in accordance with the indenture.

The obligation to pay additional amounts shall not apply to (i) any estate, inheritance, gift, sales, excise, transfer, personal property or any similar tax, assessment or other governmental charge or (ii) any tax, assessment or other governmental charge that is payable otherwise than by deduction or withholding from payments of principal or interest on the debt securities; *provided* that, except as otherwise set forth in the debt securities and the indenture, Mizuho Financial Group shall pay all stamp and other duties, if any, which may be imposed by Japan, the United States or any respective political subdivision or any taxing authority thereof or therein, with respect to the indenture or as a consequence of the issuance of the debt securities.

In addition, 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, the U.S. Treasury regulations thereunder and any other official guidance thereunder ("FATCA"), any intergovernmental agreement entered into with respect to FATCA, or any law, regulation or other official guidance enacted in any jurisdiction implementing, or relating to, FATCA, similar legislation under the laws of any other jurisdiction, or any such intergovernmental agreement.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Mizuho Financial Group shall institute proceedings seeking adjudication of bankruptcy or seeking reorganization
under the Bankruptcy Act, the Civil Rehabilitation Act, the Corporate Reorganization Act, the Companies Act or any other similar applicable law of Japan, or shall consent to the institution of any such proceedings or shall consent to the appointment
of a receiver or liquidator or trustee or assignee in bankruptcy or insolvency of itself or of all or substantially all of its property, or an effective resolution shall have been passed by Mizuho Financial Group for the winding up or dissolution of
its affairs, other than for the purpose of an amalgamation or merger, *provided* that the continuing or successor corporation in such amalgamation or merger has effectively assumed the obligations of Mizuho Financial Group under the senior debt
securities of such series and the senior indenture.

*Provision and Withholding of Notice of Default*. Pursuant to the senior indenture, the senior trustee shall give notice to the holders of the relevant series of senior debt securities of all defaults known to the senior trustee which have occurred. The senior trustee shall transmit the notice within 90 days after the occurrence of an event of default, unless the defaults have been cured before the transmission of such notice. However, except in the case of default in the payment of principal of or interest on the senior debt securities, the senior trustee may withhold notice of default if and so long as responsible officers of the trustee determine in good faith that the withholding of the notice is in the interests of the holders of the relevant series of senior debt securities.

*Acceleration Upon an Event of Default.* The senior indenture provides that, unless otherwise set forth in a supplemental indenture, if any event of default occurs and is continuing with respect to a series of senior debt securities, either the senior trustee or the holders of not less than 25% in aggregate principal amount of the outstanding senior debt securities of such series, by notice in writing to Mizuho Financial Group (and to the trustee if given by the holders), may declare the principal of and accrued interest on the senior debt securities of such series to be due and payable immediately.

***Subordinated Debt Securities***

Events of acceleration applicable to a series of subordinated debt securities will be described in an applicable prospectus supplement or free writing prospectus and set forth in the subordinated indenture relating to such series of subordinated debt securities.

**Annulment of Acceleration and Waiver of Defaults** 

In the case of senior debt securities, in some circumstances, if any or all of the events leading to acceleration under the senior indenture, other than the non-payment of the principal of the senior debt securities that has become due as a result of an acceleration, have been cured, waived or otherwise remedied, then the holders of a majority in aggregate principal amount of a series of senior debt securities may (if certain conditions are satisfied) annul past declarations of acceleration or waive past defaults of such series of senior debt securities.

Any money collected from Mizuho Financial Group by a trustee under the relevant indenture upon an event of default (in the case of senior debt securities) or any wind-up, bankruptcy or similar proceeding, subject to subordination provisions and write-down provisions that will be described in an applicable prospectus supplement or free writing prospectus and set forth in the subordinated indenture (in the case of subordinated debt securities) shall be applied in the order described below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) first, to the payment of costs, fees and expenses to the applicable trustee and any paying agent for the series

such principal and accrued and unpaid interest; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) finally, to the payment of the remainder, if any, to Mizuho Financial Group or any other person lawfully
entitled thereto.

**Indemnification of Trustee for Actions Taken on Behalf of Securityholders** 

The indentures provide or, if applicable, will provide that the trustee with respect to the relevant debt securities shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of such debt securities relating to the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred upon the trustee. In addition, the indentures contain or, if applicable, will contain a provision entitling the relevant trustee, subject to the duty of the trustee to act with the required standard of care during a default, to be indemnified to its satisfaction by the holders of relevant debt securities under the relevant indenture before proceeding to exercise any right or power at the request of such holders. Subject to these provisions and specified other limitations, the holders of a majority in aggregate principal amount of a series of debt securities outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the relevant trustee, or exercising any trust or power conferred on the relevant trustee.

**Limitation on Suits by Individual Securityholders** 

The indentures provide that no individual holder of debt securities may institute any action against Mizuho Financial Group under the relevant indenture, except actions for payment of overdue principal and interest, unless the following actions have occurred:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) offered the trustee reasonable indemnity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the trustee must have failed to institute that action within 60 days after receipt of the request referred to

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the holders of a majority in principal amount of the debt securities of the affected series, voting as one
class, must not have given directions to the trustee inconsistent with those of the holders referred to above.

However, the right of any holder of debt securities to institute suit for the enforcement of any such payment of overdue principal and interest on or after the respective due dates shall not be affected or impaired; *provided* that, in the case of subordinated debt securities, notwithstanding the foregoing, the rights of holders of subordinated debt securities specified above are subject to the limitations and suspension of rights triggered by an event triggering any write-down. For the avoidance of doubt, nothing shall be construed to impair the effectiveness of the provisions of subordination and write-down set forth in the subordinated indenture or related provisions of the subordinated debt securities.

**Covenants** 

*Consolidation, Merger, Sale or Conveyance*. The indentures contain or, if applicable, will contain provisions permitting Mizuho Financial Group, without the consent of the holders of the debt securities, to merge or consolidate with or merge into, or sell, assign, transfer, lease or convey all or substantially all of its properties or assets to any person or persons, *provided* that (i) Mizuho Financial Group is the surviving party of the consolidation or merger or sale, assignment, transfer, lease or conveyance, or (ii) the successor person or persons that is formed by such consolidation, into which Mizuho Financial Group is merged, or that acquires such properties or assets by the sale, assignment, transfer, lease or conveyance is a joint stock company (*kabushiki kaisha*) organized under the laws of Japan and assumes Mizuho Financial Group's obligations on the debt securities and under the indenture and on all series of securities issued thereunder and certain other conditions are met, including 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, has occurred and is continuing.

Before the consummation of the proposed consolidation, merger, sale, assignment, transfer, lease or conveyance, Mizuho Financial Group shall deliver an officer's certificate, and an opinion of counsel, to the effect that the conditions set forth above and in the indenture have been met. The trustee shall be entitled to rely conclusively and without liability upon such officer's certificate and opinion of counsel.

*Evidence of Mizuho Financial Group's Compliance*. There are or, if applicable, will be provisions in the indentures requiring Mizuho Financial Group to furnish to the trustee each year a brief certificate from its principal executive, financial or accounting officer as to his or her knowledge of Mizuho Financial Group's compliance with all conditions and covenants under the indenture.

**Limitation on Actions for Attachment** 

Each holder of the senior debt securities and the senior trustee acknowledge, accept, consent and agree, for a period of 30 days from and including the date upon which the Prime Minister of Japan confirms that specified item 2 measures (*tokutei dai nigo sochi*), which are the measures set forth in Article 126-2, Paragraph 1, Item 2 of the Deposit Insurance Act of Japan (Act No. 34 of 1971, as amended) (the "Deposit Insurance Act") (or any successor provision thereto), need to be applied to Mizuho Financial Group, not to initiate any action to attach any of our assets, the attachment of which has been prohibited by designation of the Prime Minister of Japan pursuant to Article 126-16 of the Deposit Insurance Act (or any successor provision thereto).

Mizuho Financial Group shall, as soon as practicable after the Prime Minister of Japan has confirmed that specified item 2 measures (*tokutei dai nigo sochi*) need to be applied to Mizuho Financial Group, deliver a written notice of such event to the senior trustee and to the holders of the senior debt securities. Any failure or delay by Mizuho Financial Group to provide such written notice shall not change or delay the effect of the acknowledgement, acceptance, consent and agreement described in the preceding paragraph.

------

##### [**Table of Contents**](#toc)
**Limited Rights to Set Off by Holders** 

Subject to applicable law, each holder of the senior debt securities, by acceptance of any interest in the senior debt securities, agrees that, if (a) Mizuho Financial Group shall institute proceedings seeking adjudication of bankruptcy or seeking reorganization under the Bankruptcy Act of Japan (act No. 75 0f 2004, as amended), the Civil Rehabilitation Act of Japan (Act No. 225 of 1999, as amended), the Corporate Reorganization Act of Japan (Act No. 154 of 2002, as amended), the Companies Act of Japan (Act No. 86 of 2005, as amended) or any other similar applicable law of Japan, and as long as such proceedings shall have continued, or a decree or order by any court having jurisdiction shall have been issued adjudging Mizuho Financial Group bankrupt or insolvent or approving a petition seeking reorganization under any such laws, and as long as such decree or order shall have continued undischarged or unstayed, or (b) the Prime Minister of Japan confirms that specified item 2 measures (*tokutei dai nigo sochi*) need to be applied to Mizuho Financial Group, 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 Mizuho Financial Group arising under, or in connection with, the senior debt securities or the senior indenture.

**Permitted Transfer of Assets or Liabilities** 

Notwithstanding certain requirements under the senior indenture relating to Mizuho Financial Group's ability to merge or consolidate with or merge into, or sell, assign, transfer, lease or convey all or substantially all of its properties or assets to any person or persons as described in "—Covenants—Consolidation, Merger, Sale or Conveyance", each holder of the senior debt securities and the senior trustee acknowledge, accept, consent and agree to any transfer of Mizuho Financial Group's assets (including shares of subsidiaries of Mizuho Financial Group) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article 126-13 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 to represent and manage and dispose of Mizuho Financial Group's assets under Article 126-5 of the Deposit Insurance Act (or any successor provision thereto), and that any such transfer shall not constitute a sale, assignment, transfer, lease or conveyance of its properties or assets for the purpose of such requirements.

**Discharge** 

Unless otherwise set forth in a supplemental indenture, Mizuho Financial Group may discharge all of its obligations with respect to any or all series of debt securities, other than as to transfers and exchanges, under each indenture after Mizuho Financial Group has, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) paid or caused to be paid the principal of and interest on all of the outstanding debt securities or such
series outstanding under the relevant indenture in accordance with their terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) delivered to the paying agent or registrar, as applicable, for cancellation all of such outstanding debt

indenture shall have been cancelled in connection with a write-down pursuant to write-down provisions set forth in the subordinated indenture.

**Modification of the Indenture** 

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. No such amendment shall in any event be effective against such creditor.

##### [**Table of Contents**](#toc)
*Modification without Consent of Holders*. Mizuho Financial Group and the trustee may enter into supplemental indentures without the consent of the holders of debt securities issued under each indenture to:

indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) add covenants for the protection of the holders of debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) cure any ambiguity or correct any inconsistency;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) add to, change or eliminate any of the provisions of the indenture (*provided* that such addition, change

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) establish the forms or terms of the debt securities of any series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) evidence the acceptance of appointment by a successor trustee; or

that is written down pursuant to any write-down, bail-in or other provisions applicable to a particular series of subordinated debt securities, to the extent that Mizuho Financial Group considers that it has
become permissible to do so under relevant laws and regulations applicable at the time of modification.

*Modification with Consent of Holders*. Mizuho Financial Group 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, may add any provisions to, or change in any manner or eliminate any of the provisions of, the indentures or modify in any manner the rights of the holders of debt securities issued under each indenture; *provided, however,* that Mizuho Financial Group and the trustee may not make any of the following changes to the terms of the debt securities, without the consent of each holder that would be affected by the change:

discount, premium, or interest on any debt securities of any series is payable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) change any of Mizuho Financial Group's obligations to pay any additional amounts on the debt securities
for any tax, assessment or governmental charge withheld or deducted (if any);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) impair the right to receive payment of the principal of and interest on any debt securities on or after the
respective due dates expressed in such debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) impair the right to institute suit for the enforcement of any payment on any debt securities when or after due;

**Concerning the 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 provide or, if applicable, 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 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 or event of acceleration, 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.

The indentures contain or, if applicable, 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 provide or, if applicable, 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 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 provide or, if applicable, will provide that the trustee with respect to a series of debt securities may resign or be removed by us, effective upon acceptance by a successor trustee of its appointment. The indentures require or, if applicable, 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 organized and doing business under the laws of the United States 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 acceptance 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 provide or, if applicable, will provide that all monies paid by Mizuho Financial Group to the trustee or paying agent for a particular series of debt securities for payment of principal or interest on any debt

------

##### [**Table of Contents**](#toc)
security which remains unclaimed at the end of two years after such payment shall become due and payable will be repaid to Mizuho Financial Group 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 look only to Mizuho Financial Group for any payment which such holder may be entitled to collect.

**New York Law to Govern** 

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

**Consent to Service of Process and Submission to Jurisdiction** 

Under the indentures, Mizuho Financial Group irrevocably designates Mizuho Bank, Ltd. as its 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 County of New York, and Mizuho Financial Group irrevocably submits to the jurisdiction of those courts.

**Methods of Receiving Payments** 

The principal of, and interest and additional amounts on, the debt securities represented by the Global Notes (as defined below) will be payable in U.S. dollars, unless the applicable prospectus supplement or free writing prospectus will specify otherwise. Subject to the terms of the relevant indenture, the paying agent will hold all sums received by it for the payment of the principal and interest on the debt securities in trust for the benefit of the holders. Mizuho Financial Group will cause the paying agent to pay such amounts received by it, on the dates payment is to be made, directly to The Depository Trust Company ("DTC").

**Book-Entry; Delivery and Form** 

***DTC***

The debt securities will initially be issued to investors only in book-entry form. Each series of debt securities will initially be in the form of one or more fully registered global notes (the "Global Notes"). The Global Notes will be issued and registered in the name of Cede & Co., acting as nominee for DTC, which will act as securities depositary for the debt securities. The Global Notes will initially be deposited with The Bank of New York Mellon, acting as custodian for DTC.

Ownership of beneficial interests in a Global Note will be limited to persons who have accounts with DTC ("participants"), or persons who hold interests through participants (including Euroclear and Clearstream). Ownership of beneficial interests in a Global Note will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants). Unless and until debt securities in certificated form are issued, the only registered holder will be Cede & Co., as nominee of DTC, or the nominee of a successor depositary.

Investors may hold their interests in a Global Note directly through DTC if they are participants in such system, or indirectly through organizations that are participants in such system, including Euroclear or Clearstream. Euroclear and Clearstream will hold interests in the Global Notes on behalf of their participants through DTC. Beneficial owners will be permitted to exercise their rights only indirectly through DTC, Euroclear, Clearstream and their participants.

DTC advises that it is a limited purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of New York Banking Law, a member of the Federal Reserve System, a

------

##### [**Table of Contents**](#toc)
"clearing corporation" within the meaning of the New York Uniform Commercial Code and a "Clearing Agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities for its participants and facilitates the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of securities certificates. Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Indirect access to the DTC system is available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly ("indirect participants").

***Euroclear***

Euroclear holds securities and book-entry interests in securities for participating organizations and facilitates the clearance and settlement of securities transactions between Euroclear participants, and between Euroclear participants and participants of certain other securities intermediaries through electronic book-entry changes in accounts of such participants or other securities intermediaries. Euroclear provides Euroclear participants, among other things, with safekeeping, administration, clearance and settlement, securities lending and borrowing, and related services. Euroclear participants are investment banks, securities brokers and dealers, banks, central banks, supranationals, custodians, investment managers, corporations, trust companies and certain other organizations. Non-participants in the Euroclear system may hold and transfer book-entry interests in the debt securities through accounts with a participant in the Euroclear system or any other securities intermediary that holds a book-entry interest in the securities through one or more securities intermediaries standing between such other securities intermediary and Euroclear.

Investors electing to acquire, hold or transfer debt securities through an account with Euroclear or some other securities intermediary must follow the settlement procedures of such intermediary with respect to the settlement of secondary market transactions in debt securities. Euroclear will not monitor or enforce any transfer restrictions with respect to the debt securities. Investors that acquire, hold and transfer interests in the debt securities by book-entry through accounts with Euroclear or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such intermediary and each other intermediary, if any, standing between themselves and the individual debt securities.

Euroclear has advised that, under Belgian law, investors that are credited with securities on the records of Euroclear have a co-property right in the fungible pool of interests in securities on deposit with Euroclear in an amount equal to the amount of interests in securities credited to their accounts. In the event of the insolvency of Euroclear, Euroclear participants would have a right under Belgian law to the return of the amount and type of interests in securities credited to their accounts with Euroclear. If Euroclear did not have a sufficient amount of interests in securities on deposit of a particular type to cover the claims of all participants credited with such interests in securities on Euroclear's records, all participants having an amount of interests in securities of such type credited to their accounts with Euroclear would have the right under Belgian law to the return of their pro rata share of the amount of interests in securities actually on deposit. Under Belgian law, Euroclear is required to pass on the benefits of ownership in any interests in debt securities on deposit with it (such as dividends, voting rights and other entitlements) to any person credited with such interests in securities on its records.

Distributions with respect to the debt securities held beneficially through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the Euroclear terms and conditions.

***Clearstream***

Clearstream advises that it is incorporated under the laws of Luxembourg and licensed as a bank and professional depositary. Clearstream holds securities for its participating organizations and facilitates the clearance and settlement of securities transactions among its participants through electronic book-entry changes in accounts of

------

##### [**Table of Contents**](#toc)
its participants, thereby 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 several countries. Clearstream has established an electronic bridge with the Euroclear operator to facilitate the settlement of trades between Clearstream and Euroclear. As a registered bank in Luxembourg, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector. Clearstream customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies and clearing corporations. In the United States, Clearstream customers are limited to securities brokers and dealers and banks, and may include the underwriters of an offering of debt securities. Other institutions that maintain a custodial relationship with a Clearstream customer may obtain indirect access to Clearstream. Clearstream is an indirect participant in DTC.

Distributions with respect to debt securities held beneficially through Clearstream will be credited to cash accounts of Clearstream participants in accordance with its rules and procedures.

***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 or free writing prospectus.

***Transfers***

Purchases of debt securities within the DTC system must be made by or through DTC participants, which will receive a credit for the debt securities on DTC's records. The ownership interest of each actual purchaser of debt securities, a beneficial owner of an interest in a Global Note, is in turn to be recorded on the DTC participants' and indirect participants' records. Beneficial owners of interests in a Global Note will not receive written confirmation from DTC of their purchases, but they are expected to receive written confirmations providing details of the transactions, as well as periodic statements of their holdings, from the DTC participants or indirect participants through which they purchased the debt securities. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of DTC participants and indirect participants acting on behalf of beneficial owners of interests in a Global Note. Beneficial owners of interests in a Global Note will not receive debt securities in certificated form representing their ownership interests in the debt securities unless use of the book-entry system for the debt securities is discontinued.

Transfers between participants in DTC 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.

Subject to compliance with the transfer restrictions applicable to the debt securities, 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

------

##### [**Table of Contents**](#toc)
during subsequent securities settlement processing and dated the clearing system 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 clearing system business day following settlement in DTC.

***Limitations on Responsibilities***

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

***DTC's Procedures for Notices, Voting and Payments***

So long as DTC, or its nominee, is the registered owner or holder of a Global Note, DTC or that nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the Global Note for all purposes under the debt securities and the indentures. No beneficial owner of an interest in a Global Note will be able to transfer that interest except in accordance with DTC's applicable procedures, in addition to those provided for under the indentures.

Mizuho Financial Group expects that DTC will take any action permitted to be taken by a holder of the debt securities, including the presentation of debt securities for exchange, only at the direction of one or more of its participants to whose account DTC's interests in the Global Notes are credited and only in respect of that portion of the aggregate, principal amount of debt securities as to which that participant or participants has or have given the direction.

Conveyance of notices and other communications by DTC to its participants, by those participants to its indirect participants, and by participants and indirect participants to beneficial owners of interests in a Global Note will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

The paying agent will send or forward any notices in respect of the debt securities held in book-entry form to DTC.

Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the debt securities unless authorized by a participant in accordance with DTC's procedures. Under its usual procedures, DTC mails an omnibus proxy to Mizuho Financial Group as soon as possible after the record date. The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those participants to whose account the debt securities are credited on the record date.

Payment of principal of and interest on the debt securities held in book-entry form will be made to Cede & Co. or another nominee of DTC by the paying agent in immediately available funds. DTC's practice is to credit its participants' accounts on the relevant payment date in accordance with their respective holdings shown on DTC's records unless DTC has reason to believe that it will not receive payments on such payment date. Payments by DTC's participants and indirect participants to beneficial owners of interests in a Global Note will be governed by standing instructions and customary practices, and will be the responsibility of those participants and indirect participants and not of DTC or Mizuho Financial Group, subject to any statutory or regulatory requirements that

------

##### [**Table of Contents**](#toc)
may be in effect from time to time. Payment of principal of and interest on the debt securities or other amounts to DTC is the responsibility of Mizuho Financial Group, disbursement of these payments to participants is the responsibility of DTC, and disbursement of those payments to the beneficial owner of an interest in a Global Note is the responsibility of participants and indirect participants.

Although DTC, Euroclear and Clearstream are expected to follow the foregoing procedures in order to facilitate transfers of interests in a Global Note among participants of DTC, Euroclear and Clearstream, they are under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither Mizuho Financial Group nor the trustees, the registrar or the paying agent will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their respective operations.

***Exchange of Global Notes for Certificated Debt Securities***

If DTC is at any time unwilling or unable to continue as a depositary for the Global Notes and a successor depositary is not appointed within 90 days, or if there shall have occurred and be continuing an event of default with respect to the senior debt securities or an event of acceleration with respect to the subordinated debt securities, Mizuho Financial Group will issue debt securities in certificated form in exchange for the Global Notes. The certificated debt securities delivered in exchange for beneficial interests in any Global Note will be registered in the names requested by or on behalf of DTC (in accordance with its customary procedures). Any such exchange shall be made free of charge to the beneficial owners of the Global Notes, except that a person receiving certificated debt securities must bear the cost of insurance, postage, transportation and other related costs in the event that such person does not take delivery of such certificated debt securities at the offices of the paying agent. The debt securities are not issuable in bearer form. Except in the limited circumstances described above, owners of interests in the Global Notes will not be entitled to receive physical delivery of debt securities in certificated form.

Payment of principal and interest in respect of the certificated debt securities shall be payable at the office of agency of Mizuho Financial Group in the City of New York which shall initially be the corporate trust office of the trustees, at 240 Greenwich Street, New York, New York 10286, U.S.A. or at the office of the paying agent (which shall initially be The Bank of New York Mellon), *provided* that, at the option of Mizuho Financial Group, payment may be made by wire transfer or by mailing checks for such interest payable to or upon the written order of such holders at their last addresses as they appear on the registry books of Mizuho Financial Group (in the case of registered securities) or at such other addresses as may be specified in the written orders of the holders; and *provided further* that, payments of any interest on certificated debt securities (other than at maturity) may be made by the paying agent, in the case of a registered holder of at least $10,000,000 principal amount of debt securities, by electronic funds transfer of immediately available funds to a United States dollar account maintained by the payee, *provided* such registered holder so elects by giving written notice to the paying agent designating such account, no later than 15 days immediately preceding the relevant date for payment (or such other date as the paying agent may accept in its discretion). Unless such designation is revoked, any such designation made by such holder with respect to such debt securities shall remain in effect with respect to any future payments with respect to such debt securities payable to such holder.

If any debt securities are listed on any securities exchange, such debt securities will be subject to any applicable rules of such securities exchange.

***Other Procedures***

The applicable prospectus supplement for subordinated debt securities may describe procedures for any write-down, write-up, bail-in or other provisions applicable to such subordinated debt securities.

------

##### [**Table of Contents**](#toc)
**Registration, Transfer and Exchange of Debt Securities** 

The registrar will maintain a register with respect to the debt securities. The name of the registered holder of each debt security will be recorded in the register. Mizuho Financial Group, the trustees, the registrar and the paying agent may treat the person in whose name any debt security is registered as the absolute owner of the debt security for all purposes and none of them shall be affected by any notice to the contrary.

At the option of the holder, subject to the restrictions contained in the debt security and in the indenture, the debt security may be transferred or exchanged for a like aggregate principal amount of debt securities of different authorized denominations, upon surrender for exchange or registration of transfer, at the registrar'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 or other documentation in a form identified in the indenture. Debt securities issued upon exchange or transfer shall be registered in the name of the holder requesting the exchange or, as the case may be, the designated transferee or transferees and delivered at the registrar's office, or mailed, at the request, risk and expense of, and to the address requested by, the designated transferee or transferees. No service charge, other than any cost of delivery not made by regular mail, shall be imposed for any transfer or exchange of debt securities, but Mizuho Financial Group or the registrar may require payment of a sum sufficient to cover any stamp duty, tax or governmental charge or insurance charge that may be imposed in connection with any transfer or exchange of debt securities.

Upon the transfer, exchange or replacement of certificated debt securities bearing the legend, the registrar will deliver only certificated debt securities bearing such legend unless Mizuho Financial Group otherwise consents.

**Authenticating Agent** 

The indentures permit or, if applicable, will permit the trustees to appoint an authenticating agent or agents with respect to the debt securities. Such authenticating agent will be authorized to act on behalf of the trustee to authenticate the debt securities and debt securities authenticated by such authenticating agent will be entitled to the benefits of the indenture and valid and obligatory for all purposes as if authenticated by the trustee. The trustee may change the authenticating agent at any time, as more fully described in the indentures.

**General** 

We may offer the debt securities described in this prospectus in one or more of the following ways from time to time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• by ourselves directly;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through a combination of any of these methods of sale.

The prospectus supplement relating to an offering of debt securities will set forth the terms of the offering, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a description of the transaction and the debt securities to be offered;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the name or names of any underwriters, dealers or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the purchase price of the debt securities and the proceeds we will receive from the sale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any underwriting discounts and commissions or agency fees and other items constituting underwriters' or
agents' compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the public offering price;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any discounts or concessions to be allowed or reallowed or paid to dealers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any securities exchanges on which the debt securities may be listed.

Any public offering prices, discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

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

------

##### [**Table of Contents**](#toc)
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 Mizuho Securities USA LLC or any other broker-dealer affiliate of ours participates in the distribution of our securities, such 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

------

##### [**Table of Contents**](#toc)
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.

**Market-Making Transactions by Affiliates** 

Mizuho Securities USA LLC or our other affiliates may use this prospectus and the applicable prospectus supplement in market-making transactions involving the debt securities after the initial sale. These transactions may be executed at negotiated prices that are related to market prices at the time of purchase or sale, or at other prices. These affiliates may act as principal or agent in these transactions. These affiliates are not obligated to make a market in any of the debt securities and may discontinue any market-making activities at any time without notice.

The debt securities to be sold in market-making transactions include debt securities to be issued after the date of this prospectus as well as debt securities issued prior to the date of this prospectus.
