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 generally will 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% 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.
S-ii

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--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.

"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

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

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

Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the U.S. Securities Exchange Act

"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 and Outlook
The effects of the outbreak of the COVID-19 Pandemic
The ongoing COVID-19 pandemic has put pressure on the global economy, including Japan. This
challenging market environment adversely affected our financial results for the fiscal year ended March 31,
2021, resulting in an increase in credit-related costs to ¥204.9 billion (including approximately ¥72.3 billion of
additional reserves recorded from a forward-looking perspective), an increase of ¥33.2 billion from the previous
fiscal year (based on Japanese GAAP). The increase in credit-related costs was due mainly to the prolonged
effects of the outbreak of the COVID-19 pandemic. For more information related to the impact that the
COVID-19 pandemic has had on our business, refer to "Item 3.D. Key Information--Risk Factors" in our most
recent annual report on Form 20-F filed with the SEC, which is incorporated by reference herein.
We currently expect that the COVID-19 pandemic will continue to have a negative impact on our
consolidated earnings and profitability through the fiscal year ending March 31, 2022 and beyond based on
management's expectation that the COVID-19 pandemic will have a prolonged impact on the global economy,
with the recovery from such impact taking until January to March of 2022 to reach the pre-COVID-19 levels
(October to December of 2019). The extent to which COVID-19 impacts our business, client and borrowers will
depend on future developments, which are highly uncertain and cannot be predicted.
Our Common Equity Tier 1 capital ratio as of March 31, 2021 improved to 9.1% (on a fully-effective basis
under the Basel III finalization framework, excluding net unrealized gains/losses on other securities, as described
in more detail in notes 12 and 13 to "Supplemental Financial and Other Information (Japanese GAAP)--Selected
Consolidated Financial Data for Mizuho Group" of this prospectus supplement), reaching our target level range.
Although we expect that our Common Equity Tier 1 capital ratio will increase during the fiscal year ending
March 31, 2022, there may be downward pressure on our capital adequacy ratios in the event that the continuing
effects of the outbreak of the COVID-19 pandemic are more significant than our management's current
expectations. However, even under such circumstances where we may experience a deterioration in net income,
we expect that our Common Equity Tier 1 capital ratio would likely remain within the target level range.
The outlook for the fiscal year ending March 31, 2022 set forth above is based on earnings estimates that we
prepared under Japanese GAAP, which is the basis of accounting that we use for financial reporting purposes in
Japan and Japanese bank regulatory purposes. We do not prepare estimates of our results of operations based on
U.S. GAAP, and it is uncertain whether our outlook for the fiscal year ending March 31, 2022 would be
substantially different if it had been based on 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. You should consult your
own professional advisers for a more complete understanding of the differences between U.S. GAAP, Japanese
GAAP and the generally accepted accounting principles of other countries and how those differences might
affect the financial information contained or incorporated by reference in this prospectus supplement or the
accompanying prospectus.
Our current expectations of the effects of the outbreak of the COVID-19 pandemic are forward-looking
statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Such
forward-looking statements are based on management's current views with respect to future events and are
subject to risks, uncertainties and assumptions. The forward-looking statements are based on specific estimates,
judgments and assumptions, including prospective assumptions about the operating environment,
macroeconomic conditions and the financial and operating conditions of our customers and counterparties. Due
to the significant risks and uncertainties associated with these estimates, judgments and assumptions, as well as
the continuously evolving nature of the COVID-19 pandemic, there can be no assurance that the actual effects of
the outbreak of the COVID-19 pandemic on our financial condition, results of operations and capital adequacy
ratios will be in line with our estimates or current expectations. We expressly disclaim any obligation or
S-2

undertaking to release any update or revision to any forward-looking statement contained herein to reflect any
change in our expectations with regard thereto or any change in events, conditions or circumstances on which
any statement is based.
See "Cautionary Statement Regarding Forward-Looking Statements" and "Item 3.D. Key Information--
Risk Factors" in our most recent annual report on Form 20-F filed with the SEC for a further discussion of risks
and uncertainties, including risks specifically related to the effects of the outbreak of the COVID-19 pandemic on
our business, financial condition and results of operations, and other factors that could cause actual results to
differ materially because of those risks and uncertainties.
