MIZUHO FINANCIAL GROUP, INC., a joint stock company (kabushiki kaisha) organized under the laws of Japan (the “Company”, which term includes any successor corporation), for value received promises to pay to CEDE & CO., or registered assigns, the principal sum of $[ ] (the “Principal”) on [ ], 20[ ] (the “Maturity Date”) and to pay interest thereon during the period from and including [ ], 20[ ] to, but excluding, [ ], 20[ ] (the “Reset Date”), [semi-annually/quarterly] in arrears on [ ] and [ ] of each year (each, a “FixedRate Interest Payment Date”), commencing on [ ], 20[ ], and ending on the Reset Date, at the rate per annum equal to [ ]% and, during the period from and including the Reset Date to, but excluding, the Maturity Date (the “Reset Fixed Rate Period”), [semi-annually/quarterly] in arrears on [ ], 20[ ] and [ ], 20[ ] (each, a “Reset Rate Interest Payment Date” and together with the Fixed Rate Interest Payment Dates, the “Interest Payment Dates” and each an “Interest Payment Date”), at the Reset Fixed Rate (as defined on the reverse of this Security), all subject to and in accordance with the terms of the Indenture referred to herein.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the person in whose name this Security is registered as at 5:00 p.m. (New York time) on the fifth Business Day immediately preceding such Interest Payment Date. If and to the extent the Company shall default in the payment of the interest due on such Interest Payment Date, such defaulted interest shall be paid to the person in whose name this Security is registered at the close of business on a subsequent record date, which shall not be less than five Business Days prior to the payment of such defaulted interest, established by notice given by mail by or on behalf of the Company to the Holder of this Security not less than fifteen days preceding such subsequent record date. Interest on this Security will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid.

Interest 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). If any payment is due on the Securities on a day that is not a Business Day, payment 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 Securities or the Indenture, and no interest will accrue on the postponed amount from the original due date to the next succeeding day that is a Business Day.

As used herein, the term “Business Day” means a day which is not a day on which banking institutions in The City of New York or Tokyo are authorized by law or regulation to close.

The principal of, and interest and Additional Amounts on, the Securities will be payable in U.S. dollars. The Company will cause the Trustee, or the paying agent, if any, to pay such amounts, on the dates payment is to be made, directly to The Depository Trust Company (“DTC”).

The Company will pay the Holder hereof Additional Amounts with respect to withholding taxes as are provided for, and subject to the conditions stated, on the reverse of this Security.

This Security is being deposited with DTC acting as depository, and registered in the name of Cede & Co., a nominee of DTC. As Holder of record of this Security, Cede & Co. shall be entitled to receive payments of principal and interest. Payments of principal and interest, including any Additional Amounts, on this Security shall be made in the manner specified on the reverse hereof and, to the extent not inconsistent with the provisions set forth herein, in the Indenture referred to herein.

The Securities constitute the direct, unconditional, unsubordinated and unsecured obligations of the Company and shall at all times rank pari passu and without preference among themselves and with all other unsecured obligations, other than subordinated obligations, of the Company (except for statutorily preferred exceptions) from time to time outstanding. The Securities are not redeemable prior to maturity, except as set forth on the reverse of this Security and will not be subject to any sinking fund.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been manually executed by or on behalf of the Trustee under the Indenture, this Security shall not be entitled to any benefits under the Indenture or be valid or obligatory for any purpose.

[ ]% Senior Callable Fixed-to-Fixed Reset Rate Notes Due 20[ ]

This Security is one of a duly authorized issue of unsecured debentures, notes or other evidences of indebtedness of Mizuho Financial Group, Inc., a joint stock company organized under the laws of Japan (herein called the “Company”, which term includes any successor person under the Indenture hereinafter referred) designated as its [ ]% Senior Callable Fixed-to-Fixed Reset Rate Notes due [ ], 20[ ] (herein called the “Securities”), issued under and pursuant to an Indenture dated as of September 13, 2016 (hereinafter called the “Indenture”), between the Company and The Bank of New York Mellon, as trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and any other indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee and any agent of the Trustee, any paying agent, the Company and the Holders of the Securities and of the terms upon which the Securities are issued and are to be authenticated and delivered.

This Security is one of the series designated on the face hereof. By the terms of the Indenture, additional Securities of this series and of other separate series, which may vary as to denomination, date, amount, stated maturity (if any), interest rate or method of calculating the interest rate and in other respects as therein provided, may be issued in an unlimited amount.

The interest rate applicable to the Securities will be reset on the Reset Date. During the Reset Fixed Rate Period, interest on the Securities shall accrue 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 Reset Determination Date (as defined below), plus [ ]% (such sum, the “Reset Fixed Rate”). Interest accrued on the Securities during the Reset Fixed Rate Period will be payable [semi-annually/quarterly] in arrears on the Reset Rate Interest Payment Dates.

The U.S. Treasury Rate shall be determined, and the Reset Fixed Rate and the Interest Amount (as defined below) payable on each Reset Rate Interest Payment Date shall be calculated, by The Bank of New York Mellon, as calculation agent (in such capacity together with any successor, the “CalculationAgent”).

“U.S. Treasury Rate” means, with respect to the Reset Fixed Rate Period, the rate per annum equal to:

(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 Reset Determination Date 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 Reset Determination Date; 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

(2)

if no information is available to determine the U.S. Treasury Rate in accordance with the method set forth in (1) above by using the Yield for at least a single New York Business Day during the five New York Business Day period described above, then the annualized yield to maturity of the Comparable Treasury Issue (as defined below) calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price (as defined below) as of the Reset Determination Date.

If the U.S. Treasury Rate cannot be determined, for whatever reason, as described under (1) or (2) above, “U.S. Treasury Rate” means the rate per annum equal to the most recently reported Yield for a New York Business Day, as determined by the Calculation Agent, 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 Reset Determination Date.

For purposes of determining the U.S. Treasury Rate, “New York Business Day” means a day which is not a day on which banking institutions in New York City are authorized by law or regulation to close, regardless of whether the over-the-counter market for actively traded U.S. Treasury securities is open or closed.

“Comparable Treasury Issue” means, with respect to the Reset Fixed Rate Period, the U.S. Treasury security selected by the Company or its Designee (and notified to the Calculation Agent) with a maturity date on or about (but not more than 30 calendar days before or after) the maturity date for the Securities and that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities denominated in U.S. dollars and having a maturity of one year; provided, however, that the selection of the Comparable Treasury Issue shall be at the sole discretion and judgement of the Company, and that such determination shall be final and conclusive for all purposes and binding on the Calculation Agent, the Trustee, the Paying Agent and the Holders of the Securities.

“Comparable Treasury Price” means, with respect to the Reset Determination Date, (i) the arithmetic average, as determined by the Calculation Agent, of the Reference Treasury Dealer Quotations (as defined below) for the Comparable Treasury Issue as of the Reset Determination Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (ii) if fewer than five such Reference Treasury Dealer Quotations are received, the arithmetic average, as determined by the Calculation Agent, of all such quotations, or (iii) if fewer than two such Reference Treasury Dealer Quotations are received, then the Reference Treasury Dealer Quotation as quoted by a Reference Treasury Dealer.

“Designee” means a designee as selected and separately appointed by the Company as designee for the Securities.

“Reference Treasury Dealer” means each of up to five banks selected by the Company or its Designee (and notified to the Calculation Agent), or the affiliates of such banks, which are (i) primary U.S. Treasury securities dealers, and their respective successors, or (ii) market makers in pricing corporate bond issues denominated in U.S. dollars; provided, however, that the selection of the Reference Treasury Dealers shall be at the sole discretion and judgement of the Company, and that such determination shall be final and conclusive for all purposes and binding on the Calculation Agent, the Trustee, the Paying Agent and the Holders of the Securities.

“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 the Company 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 Reset Determination Date.

“Reset Determination Date” means the second Business Day immediately preceding the Reset Date.

The Calculation Agent will, as soon as practicable after the determination of the Reset Fixed Rate, calculate the amount of interest (the “Interest Amount”) payable for the Reset Fixed Rate Period with respect to the Securities.

All determinations, elections, calculations and quotations made or obtained for the purposes of calculating the Reset Fixed Rate and the Interest Amount, whether by the Company, its Designee, the Calculation Agent or any Reference Treasury Dealer, in the absence of manifest error, will be final and conclusive for all purposes and binding on the Company, the Trustee, the Calculation Agent, the Paying Agent and the Holders of the Securities. In addition, notwithstanding anything to the contrary in the Indenture or the Securities, the Company may designate as its Designee an entity, which may be the Company’s affiliate, to make any determination, decision or election that the Company has the right to make for the purposes of calculating the Reset Fixed Rate 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 (with one-half cent being rounded upwards).

The Reset Fixed Rate on the Securities during the Reset Fixed Rate Period will in no event be higher than the maximum rate permitted by applicable laws and regulations or lower than 0% per annum.

The Calculation Agent will cause the Reset Fixed Rate, the Interest Amount payable for the Reset Fixed Rate Period and the relevant Reset Rate Interest Payment Date with respect to the Securities to be notified to the Company, the Trustee, the Paying Agent and DTC, and such information will be notified or published to the Holders of the Securities through DTC or through another reasonable manner as soon as possible after their determination.

The principal of and interest (and any Additional Amounts) on the Securities shall be payable in U.S. Dollars or in such other coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts. So long as any of the Securities are held in global form, payments of principal and interest on such Securities shall be made by wire transfer in immediately available funds in U.S. Dollars to a bank account in The City of New York designated by the Holder of this Registered Global Security. Otherwise, (i) the principal amount of the Securities will be payable by check, drawn on a bank in The City of New York, upon the presentation and surrender of the Securities at the Specified Corporate Trust Office of the Trustee or at any office or agency maintained by the Company for such purpose and (ii) interest on the Securities will be payable by wire transfer or check, drawn on a bank in The City of New York, mailed to the persons in whose names the Securities are registered as of 5:00 p.m. (New York time) on the fifth Business Day immediately preceding the applicable Interest Payment Date (or the subsequent record date in the case of a defaulted interest payment) at the addresses of such persons as shall appear in the Security register of the Company; provided, however, that at the option of a Holder in whose name at least $10,000,000 principal amount of Securities are registered, all payments in respect of the Securities may be received by electronic funds transfer of immediately available funds to a U.S. dollar account maintained by the payee, provided such registered Holder so elects by giving written notice to the Trustee designating such account, no later than fifteen days immediately preceding the relevant date for payment (or such other date as the Trustee may accept in its discretion).

All payments of principal and interest in respect of the Securities by the Company 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, the Company shall pay to the holder of each 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 Security in the absence of such withholding or deduction, provided that, no such Additional Amounts shall be payable in relation to any such withholding or deduction in respect of any payment on the Securities:

(a) to or on behalf of a Securityholder or beneficial owner of a 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 Security by reason of its (1) having some connection with Japan other than the mere holding of such Security, or (2) being a person having a special relationship with the Company as described in Article 6, Paragraph 4 of the Act on Special Measures Concerning Taxation of Japan (Act No. 26 of 1957) (the “Special Taxation Measures Act”) (a “Specially-Related Person of the Company”); or

(b) to or on behalf of a Securityholder or beneficial owner of a 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 the Company 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; or

(c) to or on behalf of a Securityholder or beneficial owner of a 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 the Company, by reason of such individual resident of Japan or Japanese corporation receiving interest on the relevant Security through a payment handling agent in Japan appointed by it); or

(d) to or on behalf of a Securityholder or beneficial owner of a Security who presents a Security for payment (where presentation is required) more than 30 days after the Relevant Date (as defined below), except to the extent that such Securityholder or beneficial owner of a Security would have been entitled to such Additional Amounts on presenting the same for payment on any date during such 30-day period; or

(e) to or on behalf of a Securityholder 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 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 Security; or

(f) any combination of (a) through (e) above.

Where a 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 the Company for, or on account of, Japanese Taxes, if the relevant beneficial owner of a Security is (1) an individual non-resident of Japan or a non-Japanese corporation that in either case is not a Specially-Related Person of the Company or (2) a Japanese financial institution (a “Designated Financial Institution”) falling under certain categories prescribed by Article 6, Paragraph 9 of the Special Taxation Measures Act and the cabinet order thereunder (Cabinet Order No. 43 of 1957), as amended (together with the ministerial ordinance and other regulations thereunder, the “Act”), all in accordance with the Act, such beneficial owner of a Security must, at the time of entrusting a Participant with the custody of the relevant Security, provide certain information prescribed by the Act to enable the Participant to establish that such beneficial owner of a 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 Security ceases to be so exempted including the case where the relevant beneficial owner of the Security who is an individual non-resident of Japan or a non-Japanese corporation becomes a Specially-Related Person of the Company.

Where a Security is not held by a Participant, in order to receive payments free of withholding or deduction by the Company for, or on account of, Japanese Taxes, if the relevant beneficial owner of a 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 the Company or (ii) a Designated Financial Institution, all in accordance with the Act, such beneficial owner of a Security must, prior to each date on which it receives interest, submit to the Company 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 the Company 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 Security, the title of the Securities, the relevant Interest Payment Date, the amount of interest payable and the fact that such beneficial owner of a Security is qualified to submit the Written Application for Tax Exemption, together with documentary evidence regarding its identity and residence.

As used herein, the “Relevant Date” means the date on which any payment in respect of a 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 Securityholders in accordance with the Indenture.

The obligation to pay Additional Amounts shall not apply to (i) any estate, inheritance, gift, excise, sales, 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 Securities; provided that, except as otherwise set forth in the Securities and the Indenture, the Company 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 Securities.

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.

The Securities may, subject to the prior confirmation of the Financial Services Agency of Japan (if and to the extent required under the then-applicable Japanese banking laws or regulations), be redeemed at the option of the Company in whole, but not in part, on [ ], 20[ ], at a redemption price equal to 100% of the principal amount of the Securities then outstanding plus accrued and unpaid interest to but excluding the date fixed for redemption, upon sending, or causing to be sent by first-class mail, postage prepaid, to the Trustee and to the Holders of the Securities, notice of such redemption at not less than 15 days and not more than 60 days prior to the date fixed for redemption to such Holders of Securities at their last addresses as they shall appear upon the registry books. The notice of redemption shall specify the election of the Company to redeem the Securities, the date fixed for redemption, the redemption price, the principal amount and CUSIP or ISIN number and/or common code of each Security held by such Holder to be redeemed, that on the redemption date the redemption price will become due and payable upon each Security to be redeemed, that interest thereon will cease to accrue on and after the redemption date and the place or places where the Securities to be redeemed are to be surrendered for payment of the redemption price and that (in the event the Securities are in certificated form) the Securities 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.

The notice of redemption of Securities of any series to be redeemed at the option of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company, in which case the Company shall make such request no later than 5 Business Days prior to the conclusion of the notice period above.

Any notice which is mailed in the manner as provided herein shall be conclusively presumed to have been duly given, whether or not the Holder receives the notice. Failure to give notice by mail, or any defect in the notice, to the Holder of any Security of a series designated for redemption shall not affect the validity of the proceedings for the redemption of any other Security of such series.

Notwithstanding any of the foregoing, the Company may give such notice in any manner permitted or required by DTC.

The Securities may, subject to the prior confirmation of the Financial Services Agency of Japan (if and to the extent required under the then-applicable Japanese banking laws or regulations), be redeemed at the option of the Company in whole, but not in part, at any time, upon not less than 30 nor more than 60 days prior notice thereof given by the Company, at a redemption price equal to 100% of the principal amount of the Securities then outstanding (together with accrued and unpaid interest to (but excluding) the date fixed for redemption and Additional Amounts, if any), if, 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 [ ], 20[ ], the Company is, or on the next Interest Payment Date would be, required to pay any Additional Amounts to holders of the Securities which obligations cannot be avoided by measures reasonably available to the Company; provided that, no such notice of redemption may be given earlier than 90 days prior to the earliest date on which the Company would be obligated to make such payment of Additional Amounts if a payment in respect of the Securities were then due. Prior to the mailing to holders of Securities of any notice of redemption of the Securities, the Company shall certify to the Trustee that the requirements for redemption have been met and deliver therewith to the Trustee an opinion of an independent tax counsel or tax consultant of recognized standing, such opinion to be reasonably satisfactory to the Trustee, to the effect that the circumstances referred to above exist. The Trustee shall be entitled to 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 Securityholders.

A Holder of Securities issued in definitive form may transfer or exchange Securities in accordance with the Indenture. As described in the legend on the face of this Registered Global Security, interest payments on such Securities issued in definitive form will be subject to Japanese income taxation unless the Holder establishes the matters set forth therein. Such legend concerning Japanese taxation shall also be included on the face of any Securities issued in definitive form. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and to pay any taxes and fees required by law or permitted by the Indenture. The Company will treat the registered Holder of a Security as the owner of that Security for all purposes, except as described above.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of all series to be affected (voting as a class). The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the security registrar duly executed by, the Holder hereof or his attorney duly authorized in writing and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in denominations of $[ ] and integral multiples of $[ ] in excess thereof.

In connection with the registration statement (the “Registration Statement”) on Form F-3 (File No. 333-233354) relating to debt securities of Mizuho Financial Group, Inc.

We have also examined such certificates and corporate documents of the Issuer and such other matters, documents and records, and considered such questions of the laws of Japan, as we have deemed necessary or appropriate for the purpose of rendering the opinion hereinafter set forth.

Having examined the above documents and having regard to the laws of Japan which we deem relevant, and subject to the assumptions and qualifications specified herein, we are of the opinion that:

The Notes, when payment for the Notes has been duly made in full in accordance with the Underwriting Agreement, and when the Global Certificates have been duly signed on behalf of the Issuer by a Representative Executive Officer of the Issuer or persons named in the Power of Attorney, duly authenticated and delivered in accordance with the terms of the Underwriting Agreement, the Indenture and the Notes, and assuming that the Notes will constitute valid and legally binding obligations of the Issuer enforceable in accordance with their terms under their governing law, to which they are subject and as to which we render no opinion, will constitute valid and legally binding obligations of the Issuer enforceable in accordance with their terms.

We have assumed, for the purpose of rendering this opinion, that (i) all signatures or seal impressions on any documents we reviewed are true and genuine; (ii) all documents submitted to us as originals are authentic and complete; (iii) all documents submitted to us as copies are complete and conform to the originals thereof that are authentic and complete; (iv) all documents submitted to us as forms are executed in such forms; (v) statements included, expressly or impliedly, in the documents, record and certificate of the Issuer or public officials are true and conform to the relevant facts thereof; (vi) all natural person-signatories who have executed or delivered the Underwriting Agreement, the Indenture and other documents related thereto on behalf of the relevant parties thereto have and had at the relevant times the sufficient and competent legal capacity to take such actions; (vii) each party (other than the Issuer) to each of the Underwriting Agreement, the Indenture and other relevant documents is an entity duly organized, validly existing and, where applicable, in good standing under the laws of the jurisdiction of its organization, and has full and complete power and authority (corporate or otherwise) to execute and deliver, and to perform its obligations under, such document; (viii) each of the Underwriting Agreement, the Indenture and other relevant documents is within the capacity and powers of and has been duly authorized by all the parties thereto (other than the Issuer); (ix) each of the Underwriting Agreement, the Indenture and other relevant documents has been duly executed and delivered by all the parties thereto (other than the Issuer); (x) nothing in the applicable law of any jurisdiction other than Japan would conflict with, or preclude the performance, legality, validity, effectiveness or enforcement of, the Notes and the Underwriting Agreement, the Indenture and other relevant documents; and (xi) the Underwriting Agreement, the Indenture and other relevant documents are legal, valid and binding on the parties thereto and enforceable in accordance with their respective terms under their respective governing laws (other than the laws of Japan). We have not independently verified any of the matters referred to in (i) through (xi) above.

The foregoing opinion is based on the assumptions, qualified by and subject to the limitations, set forth below:

---	---
(ix)	In the opinion herein, Japanese legal concepts are expressed in English terms and not in their original<br>Japanese terms. The concepts concerned may not be identical to the concept described by the equivalent English terms as they exist under the laws of other jurisdictions. We do not render any opinion as to how judges qualified in a foreign<br>jurisdiction would interpret Japanese legal concepts or expressions, and this opinion may only be relied upon under the express condition that any issues of interpretation or liability arising thereunder will be governed by the laws of Japan and be<br>brought before a Japanese court;

Opinion of Simpson Thacher & Bartlett LLP

Exhibit 5.2

February 22, 2021

Mizuho Financial Group, Inc.

1-5-5 Otemachi, Chiyoda-ku

Tokyo 100-8176, Japan

Ladies and Gentlemen:

We have acted as United States counsel to Mizuho Financial Group, Inc., a joint stock company incorporated with limited liability under the law of Japan (the “Company”), in connection with the Registration Statement on Form F-3 (File No. 333-233354) (the “Registration Statement”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”) under the U.S. Securities Act of 1933, as amended, relating to the issuance by the Company of U.S.$1,400,000,000 aggregate principal amount of 1.234% Senior Callable Fixed-to-Fixed Reset Rate Notes due 2027 and U.S.$600,000,000 aggregate principal amount of 2.172% Senior Callable Fixed-to-Fixed Reset Rate Notes due 2032 (collectively, the “Securities”) pursuant to the Senior Indenture, dated as of September 13, 2016 (the “Indenture”), between the Company and The Bank of New York Mellon, as trustee (the “Trustee”).

We have examined the Registration Statement, the Indenture, the Officer’s Certificate, dated as of February 22, 2021, delivered pursuant to the Indenture establishing the terms of the Securities, duplicates of the global notes representing the Securities, and the underwriting agreement, dated February 16, 2021 (the “Underwriting Agreement”), between the Company and the several underwriters named in Schedule A thereto. In addition, we have examined, and have relied as to matters of fact upon, originals, or duplicates or certified or conformed copies, of such records, agreements, documents and other instruments and such certificates or comparable documents of public officials and of officers and representatives of the Company and have made such other investigations as we have deemed relevant and necessary in connection with the opinions hereinafter set forth.

In rendering the opinion set forth below, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents. We have also assumed that the Indenture is the valid and legally binding obligation of the Trustee.

In rendering the opinion set forth below, we have assumed further that (1) the Company has been duly incorporated and is validly existing under the law of Japan and has duly authorized, executed, issued and delivered the Indenture, the Securities and the Underwriting Agreement, as applicable, in accordance with its Articles of Incorporation, its Regulations of the Board of Directors and the law of Japan, (2) the execution, issuance, delivery and performance by the Company of the Indenture, the Securities and the Underwriting Agreement, as applicable, do not constitute a breach or violation of its Articles of Incorporation or its Regulations of the Board of Directors or violate the law of Japan or any other jurisdiction (except that no such assumption is made with respect to the federal law of the United States or the law of the State of New York) and (3) the execution, issuance, delivery and performance by the Company of the Indenture, the Securities and the Underwriting Agreement, as applicable, do not constitute a breach or default under any agreement or instrument which is binding upon the Company.

Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that assuming due authentication of the Securities by the Trustee, and upon payment and delivery in accordance with the provisions of the Underwriting Agreement, the Securities will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms.

Our opinion set forth above is subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, (ii) general equitable principles (whether considered in a proceeding in equity or at law), (iii) an implied covenant of good faith and fair dealing and (iv) the effects of the possible application of foreign laws or foreign governmental or judicial action affecting creditors’ rights. In addition, we express no opinion with respect to Section 4.13 of the Indenture relating to indemnification of judgment currency.

In connection with the provision of the Indenture whereby the parties submit to the jurisdiction of U.S. federal courts located in the Borough of Manhattan, The City of New York, we note the limitations of 28 U.S.C. Sections 1331 and 1332 on subject matter jurisdiction of the U.S. federal courts. In connection with the provision of the Indenture which relates to forum selection (including, without limitation, any waiver of any objection to venue or any objection that a court is an inconvenient forum), we note that under N.Y.C.P.L.R. Section 510, a New York State court may have discretion to transfer the place of trial, and under 28 U.S.C. Section 1404(a), a U.S. federal district court has discretion to transfer an action from one U.S. federal court to another. We also note that the recognition and enforcement in New York State courts or U.S. federal courts sitting in the State of New York of a foreign judgment obtained against the Company is subject to the Uniform Foreign Money—Judgments Recognition Act (53 N.Y.C.P.L.R. §5301 et seq.).

We do not express any opinion herein concerning any law other than the law of the State of New York and the federal law of the United States.

We hereby consent to the filing of this opinion letter as Exhibit 5.2 to the Form 6-K of the Company filed with the Commission on February 22, 2021 in connection with the offer and sale of the Securities by the Company for incorporation into the Registration Statement and to the use of our name under the caption “Legal Matters” in the prospectus included in the Registration Statement.

Very truly yours,
