If MUFG is the “most international megabank” and SMBC is the “most aggressively digital megabank,” then Mizuho Bank is squarely the “megabank that’s gone deepest with Rakuten.” Founded in 2002 by merging Dai-Ichi Kangyo Bank, Fuji Bank, and the Industrial Bank of Japan — three Tokyo-based heavyweights — Mizuho has the longest institutional history and the most stable client base of the three, though it has tended to keep a lower public profile than the other two. That changed in 2024. Mizuho FG’s acquisition of 14.99% of Rakuten Card (agreed Nov 2024, closed Dec 2024), the launch of the Mizuho Rakuten Card, and the joint Rakuten Securities project together made Mizuho the only megabank in Japan fully wired into the Rakuten ecosystem. Add the long-running Aeon Bank ATM partnership (started 2013, harmonised fees in 2024) and the major Feb–Mar 2026 simplification of Mileage Club, and Mizuho’s appeal to foreign residents in Japan is at an all-time high. This guide uses 180+ authoritative sources to lay out everything Mizuho actually does well — especially the “Rakuten-native” combinations no other megabank can match.

1. Mizuho Financial Group: One of Japan’s Oldest Megabanks

Most people’s first impression of Mizuho is “the three-bank merger.” That’s accurate but misses the point. The group structure and the recent strategic pivot are what actually define Mizuho’s place among the three megabanks today.

1.1 Mizuho FG: size and history

Headline figures (FY2024–2025):

• Retail accounts: ~24 million (about 20% of Japan’s population — roughly 1 in 5 people)
• Domestic branches: ~310 projected (Kyodo News reported in Mar 2025 that 6 branch consolidations would complete by end of FY2025, bringing the network to ~310; previously over 460)
• International network: branches, representative offices, and local subsidiaries in 40+ countries and regions
• Total assets: ~¥237 trillion
• Corporate lending: relationships with ~70% of all listed companies in Japan
• Headcount: ~50,000 (still undergoing structural reform)

1.2 The legacy of a three-bank merger

Mizuho’s roots are unusually complex — each of the three predecessor banks brought a distinct DNA:

1.3 Key Mizuho FG subsidiaries

Why the group structure matters for individuals: a single Mizuho ID lets you stack benefits across subsidiaries. The promos compound when you operate as one customer across multiple Mizuho services.

2. Opening an Account as a Foreign Resident

Mizuho’s foreigner eligibility is reasonably flexible and the app-based opening flow is well built out. This section breaks down the three opening paths and when to use each.

2.1 Who can open a Mizuho account?

Foreign-national eligibility:

• ✅ 6+ months of residence in Japan is the baseline
• ✅ Under 6 months still qualifies if you’re a full-time employee (正社員/seishain) at a Japanese company (submit a copy of your employee ID or certificate of employment)
• ✅ Special Permanent Residents and Permanent Residents have no minimum-stay requirement
• ✅ Valid Residence Card with 3+ months of remaining validity
• ✅ Living in Japan
• ✅ Students and technical interns must additionally submit a student ID or enrollment certificate

2.2 Comparing the three opening paths

2.3 Required documents — full checklist

2.4 The app-opening flow, step by step

1. Download “Mizuho Account Opening & Procedures app” from the App Store or Google Play. Important: this is a dedicated opening app, NOT the Mizuho Direct app (which is the online-banking app).
2. Pick the foreign-national flow. The app prompts you for residency status, date of entry, etc.
3. Photograph your Residence Card — front and back. The OCR fills in fields automatically. Your address must match the card exactly.
4. Identity verification (selfie). The eKYC flow inside the app handles facial verification.
5. Pick add-on services. Strongly recommended to bundle all of:
   ① Mizuho Direct (online banking)
   ② Mizuho Rakuten Card (no annual fee + Rakuten Points)
   ③ Mizuho Mileage Club enrollment
   ④ Mizuho JCB Debit (fallback if credit screening fails)
6. Choose your home branch. Pick one near your address or workplace. Branches far from your address may be rejected.
7. Receive the completion email. Branch number and account number arrive within 1–7 days of approval. Same-day is possible.
8. Download the Mizuho Direct app. Complete first-time setup and you can immediately check balances and send transfers.
9. Wait for the cash card. Arrives in 1–2 weeks via “simplified registered, non-forwarding” mail.

2.5 Multilingual support — what’s actually there

Mizuho’s opening documentation for foreigners is unusually thorough:

• Account opening / Residence Card pages: 5-language PDFs (English, Simplified Chinese, Traditional Chinese, Korean, Vietnamese)
• Sample application forms: 5-language PDFs
• Mizuho Direct app: Japanese and English only (it was the first Japanese bank app to support English, Sep 2015)
• Mizuho Securities Net Club: Japanese only

2.6 Notification after Residence Card renewal

3. Mizuho’s 5 Unique Strengths

This is the core differentiation section. Most articles describe Mizuho as “lots of branches, stable” — but these five points are what the other megabanks actually can’t easily match.

4. Mizuho Rakuten Card: The Complete Guide

The flagship product of Mizuho’s alliance strategy, launched 3 Dec 2024. We use a stacked-visual view to make it obvious where the “effective 2% cashback” actually comes from. Note carefully: the W-Point Plan only runs for the first year after enrollment.

4.1 Mizuho Rakuten Card — basic specs

4.2 W-Point Plan visualised (first year only)

4.3 What Mizuho Points are good for

Mizuho Points accumulate across various Mizuho Bank transactions and can be converted as follows:

• Conversion to Rakuten Points (Mizuho Rakuten Card holders)
• Conversion to other-company points (d Points, PayPay Points, etc.)
• 1 point = ¥1 equivalent

4.4 SPU (Rakuten Ichiba Super Point Up Program) — how to use it

Using the Mizuho Rakuten Card on Rakuten Ichiba unlocks a baseline +2× SPU boost:

5. Mileage Club Perks (“うれしい特典”) — the 2026 Reform Explained

This is the biggest Mizuho Bank story of 2026. The phased rollout starting 15 Feb 2026 radically simplified the program, giving Mizuho the most user-friendly membership scheme of any megabank.

5.1 Before-and-after comparison

5.2 Rollout schedule (4 phased waves)

5.3 The power move: “Pay subscriptions on the Mizuho Rakuten Card” → permanent S Stage

6. The Complete ATM Fee Guide

Mizuho’s ATM network is the widest of the three megabanks — Mizuho officially markets it as the “#1 ATM network among megabanks”. The Aeon Bank tie-up is the biggest differentiator.

6.1 Mizuho Bank ATMs

6.2 Aeon Bank ATMs (same fee tier as Mizuho!)

6.3 Partner konbini ATMs (E-net, Lawson Bank, Seven Bank)

6.4 SMBC and Resona Bank ATMs, etc.

Mizuho cards work at SMBC’s and Resona Bank’s off-branch ATMs (those with the partnership sticker) at the standard fee schedule.

6.5 The power move: “25th salary date” + “S Stage” = lifetime ¥0 ATM

7. Overseas Wire Transfers in Depth

International banking has been a traditional Mizuho strength. Rates in this section are as of April 2026.

7.1 Receiving overseas remittance (inward)

7.2 Sending overseas remittance (outward)

7.3 Supported currencies and limits

7.4 Choosing the right remittance method

8. Where Mizuho’s Transfer Fees Actually Win

The Jan 2025 revision dropped Mizuho Direct outbound transfers to other banks to ¥110 — currently the lowest among the three megabanks.

8.1 Transfer fee table

8.2 Kotora transfer (¥0 for under-¥100k family transfers)

Mizuho fully supports Kotora — the small-amount inter-bank transfer rail in Japan (under ¥100k, ¥0 between participating banks). Family transfers under ¥100k are completely free. See our Kotora transfer guide for details.

8.3 Strategic use

9. Mizuho Wallet and J-Coin Pay

The two pillars of Mizuho’s cashless payment strategy.

9.1 Mizuho Wallet

Mizuho Wallet is Mizuho’s smartphone payment app, bundling these three services:

9.2 J-Coin Pay

J-Coin Pay is a transfer and payment app, anchored by Mizuho and connected with 60+ regional banks:

• Transfers, receipts, and payments handled entirely on smartphone
• P2P transfers ¥0 and instant
• Top-up to / withdraw to bank account ¥0
• Easy KYC with My Number Card (from 22 Nov 2024)
• Periodic 20%-reward campaigns tied to Mizuho Wallet

9.3 The reality check vs. PayPay and Rakuten Pay

Honest take: Mizuho’s Wallet-family payments are not as widely accepted as PayPay or Rakuten Pay. Usable contexts are limited. For day-to-day primary payments, the Mizuho Rakuten Card + Rakuten Pay combination is the strongest stack.

10. Power-User Tactics

This section covers genuinely advanced moves — material that’s rare to find written up clearly.

10.1 The full Rakuten Securities integration setup

10.2 The autopay → instant-sell arbitrage (Mizuho version)

Mizuho Rakuten Card autopay → immediate sale → Rakuten Points retained. Details in our autopay-arbitrage guide.

10.3 The two-step play with a Mizuho Securities account

Opening a Mizuho Securities account also unlocks:

• Contributes to the Mileage Club “¥3M+ combined balance” condition (month-end balances of JGBs, mutual funds, equities, etc. all count)
• IPO lottery participation (Mizuho Securities is a frequent lead manager, ~20% underwriting share)
• Comprehensive U.S. bond lineup, etc.
• From 16 Feb 2026, the Shared Account Opening System with Rakuten Securities is live → smoother procedure

10.4 Maxing out the New Life Campaign 2026

The New Life Campaign 2026 (27 Jan 2026 – 11 Jun 2026) is currently running as of April 2026:

10.5 Mizuho Referral Program (みずほ銀行ご紹介プログラム) — ¥1,000 each for both sides

Separately from the seasonal New Life Campaign, Mizuho runs a standing official referral program. Both the referrer (an existing customer) and the referee (the new applicant) each receive ¥1,000-equivalent in Mizuho Points — a perennial bonus you can use any time of year. Details on the official Mizuho referral program page.

📝 How to claim — 3-step process

10.6 Mizuho e-account + Mizuho Direct passbook

Accounts opened from 2021 onward default to “Mizuho e-account.” Maximise its value:

• Completely avoid the ¥1,100/book paper-passbook fee
• Mizuho Direct passbook shows up to 10 years of transaction history
• Tax-filing transaction statements available digitally
• No passbook reissue needed when moving
• Note: since 15 Dec 2021, the automatic paper-to-e switchover is suspended. No restart has been announced as of writing

10.7 Timing your Mizuho Securities × Rakuten Securities openings

On 5 Feb 2026, Mizuho Securities and Rakuten Securities announced the joint “Shared Account Opening System,” which went live 16 Feb 2026. From 10 Mar 2026, Rakuten Securities also serves as Mizuho Bank’s banking agent — you can open a Mizuho account directly from the Rakuten Securities site. If you want all three accounts (Mizuho Bank + Mizuho Securities + Rakuten Securities) opened simultaneously, these new routes are the smoothest path.

11. Mizuho’s Weaknesses and Workarounds

Mizuho is not perfect. The real gaps, and what to do about them:

12. Account Opening FAQ

Q1: Can I really open a Mizuho account with under 6 months in Japan?

Yes — if you’re working as a full-time employee at a Japanese company, you can apply with under 6 months in Japan by submitting a copy of your employee ID or certificate of employment. The legal bar at MUFG and SMBC is essentially the same. MUFG’s official policy is “employed in Japan (excluding part-time/casual) OR 6+ months since entry, either one.” Mizuho’s real edge is the smoother app handling and the comprehensive 5-language PDF guides. “Only Mizuho is flexible” is overstated marketing — compare all three banks before deciding. Pre-employment offers, dispatch workers, contract employees, part-timers, and students with old Residence Card copies are typically not eligible.

Q2: Can I hold both a Mizuho Rakuten Card and a regular Rakuten Card?

Yes — you can hold both. The “second-card enrollment campaign” means existing Rakuten Card holders applying for the Mizuho Rakuten Card as a second card still qualify for the new-enrollment bonus. Some SPU perks may not stack across both cards, though.

Q3: Is the W-Point Plan really not permanent?

Correct — it is not permanent. The W-Point Plan terms:

• Eligible: new applicants from 30 Jun 2025 onward with direct-debit setup complete
• Up to 12 months from card enrollment
• Mizuho Points capped at 10,000 total
• After 12 months OR hitting the cap, reverts to 1% (same as regular Rakuten Card)

Anything claiming “permanent 2% reward” is wrong. ¥40k–50k/month spend reaches the cap inside a year — concentrate subscriptions and daily payments on this card to take the full cap in year one.

Q4: Do I really need to clear Mileage Club conditions every month?

Yes. Mileage Club status is assessed at end of each month; satisfying the conditions earns you perks for the month after next. To keep S Stage, you must clear the conditions each month. Setting up a recurring subscription handles this automatically.

Q5: Can I convert back to a paper passbook from the Mizuho e-account?

Yes — by phone or at a Mizuho branch. If you were auto-converted to “Mizuho e-account” by Mizuho, reissuing a paper passbook is free (¥1,100 if you originally opted into e-account yourself). From Feb–Mar 2026, S Stage members get free passbook renewal, so reaching S Stage lets you keep a paper passbook at no cost. Delivery takes 7–10 business days. Note: since 15 Dec 2021, the automatic paper-to-e switchover is suspended; no restart has been announced.

Q6: Does the Mizuho Direct app support Chinese?

Unfortunately no — the app only supports Japanese and English, not Chinese. If you need Chinese, MUFG (5 languages) is the better fit. That said, Mizuho’s account-opening PDFs are available in 5 languages — use them as a reference at sign-up time.

Q7: How do I close the account when I leave Japan?

Contact your opening branch for the closure procedure. Reach out via Mizuho Direct in advance. Any remaining balance can be withdrawn and wired to an overseas account (wire fees apply).

Q8: When does the Mizuho Rakuten Card arrive?

About 1–2 weeks after enrollment, by simplified registered mail. The mail is non-forwarding, so your registered address must match your current address.

Q9: Is opening a Rakuten Securities account alone enough for the SPU bonus?

To earn the +0.5× SPU you need ¥30,000+ in monthly point investment (mutual funds or JPY-denominated U.S. stocks). Setting credit-card autopay at ¥30,000+/month clears this automatically.

Q10: What’s the difference between Mutual-fund Smart Autopay and Rakuraku Deposit?

Mutual-fund Smart Autopay auto-debits Mizuho when your Rakuten Securities mutual-fund autopay runs (no manual funding step). Rakuraku Deposit is the instant-transfer service you use when you manually move money into Rakuten Securities. Both are ¥0, but they serve different purposes.

Q11: Does just having a Mizuho account get me into Mileage Club S Stage?

No — you must satisfy at least one of the 3 Mileage Club conditions: ① one card use per month, ② salary/pension deposit, or ③ ¥3M+ balance. The easiest path is charging a subscription to the Mizuho Rakuten Card.

Q12: Can I really open a Mizuho account directly from Rakuten Securities?

Yes. From 10 Mar 2026, Rakuten Securities is officially a banking agent for Mizuho, and you can apply for a Mizuho account directly from the Rakuten Securities website. For anyone who wants a Rakuten Securities account and a Mizuho account opened together, this is the smoothest new route. For foreign-national applicants, the document submission flow may differ slightly from the standard Mizuho app route, so check Mizuho’s official guidance for your specific case before applying.

13. Summary: Who Is Mizuho Bank Best For?

Across all dimensions, Mizuho is the strongest fit for:

• ✅ Heavy Rakuten ecosystem users (Rakuten Ichiba, Rakuten Securities, Rakuten Mobile, etc.)
• ✅ People who refuse to pay credit-card annual fees but want high reward rates in year one (Mizuho Rakuten Card has no annual fee + 10,000P W-Point bonus in year one)
• ✅ Recently-arrived foreign professionals on full-time contracts (open without waiting 6 months — the legal bar is the same at all three megabanks, but Mizuho operates the process smoothly)
• ✅ People living in regional cities who frequently use Aeon Mall and supermarkets (Aeon ATM network)
• ✅ People who prefer a simple membership scheme (the post-reform Mileage Club is the simplest)
• ✅ People building wealth through a bank-brokerage stack (deep Rakuten Securities link)
• ✅ Subscription-heavy / cashless-first users (one card use per month = permanent S Stage)
• ✅ Anyone targeting the 2026 New Life Campaign (up to ¥40,000-equivalent in points)

Mizuho is NOT the right fit if:

• ❌ You need Chinese, Korean, or Vietnamese app support → MUFG
• ❌ You want to open a U.S. Bank account before arriving → MUFG‘s U.S. Bank intermediation
• ❌ You’re chasing 20% reward at 7-Eleven / Lawson → SMBC + Olive
• ❌ You want SBI Securities as your primary brokerage → SMBC
• ❌ You want a permanently 2%+ reward credit card → consider Mitsui Sumitomo Card Gold (NL), JCB CARD W, etc. (the Mizuho Rakuten Card W-Point is first-year only)
• ❌ You’re fully online-only → online banks like Rakuten Bank, Sumishin SBI, PayPay Bank
• ❌ Short-term stay (under 6 months) without full-time employment → Japan Post Bank (Yucho)
