How to Open a Bank Account in Japan as a Foreigner: Which Banks Actually Work

Last updated: July 2026 · 9 min read

Quick summary: Most foreigners try to open a bank account at a major Japanese bank, get rejected, and assume they can’t open one at all. That assumption is wrong — and it costs them weeks of financial limbo. Japan Post Bank (ゆうちょ) and Rakuten Bank both accept foreigners without the “6-month residency” requirement that only applies to megabanks. This guide explains the bank-by-bank rules, the documents you actually need, and the one My Number mistake that trips up almost everyone.

1. Why Japanese banks reject foreigners (and why most guides get this wrong)

Here is the scene that plays out for thousands of foreigners every month in Japan: you arrive, find your apartment, and head to the nearest Mitsubishi UFJ or Mizuho branch to open a bank account. You need it to receive your salary, pay rent, and set up utilities. The staff politely tells you it is not possible and sends you away without a clear explanation.

You search online and find dozens of English guides that say you need to wait six months. So you wait. Then you find out that your colleague — who arrived the same week — has had a Japan Post Bank account for a month already.

The “six-month rule” is real, but it only applies to certain banks. It is not a universal legal requirement. Japan’s Anti-Money Laundering regulations require banks to verify stable residency before opening an account, but each bank interprets and applies this requirement differently. Understanding the actual hierarchy — which banks accept new arrivals and which don’t — is the entire game.

The Financial Services Agency (金融庁) has published guidance encouraging banks to be more accessible to foreign residents, but individual bank policies still vary widely in 2026.

2. The bank tier list: easiest to hardest for new arrivals

Not all Japanese banks are equally accessible to foreigners. Here is the honest ranking based on the actual requirements in 2026:

Tier 1 — Easiest for new arrivals (under 6 months in Japan)

ゆうちょ銀行 (Japan Post Bank)

ゆうちょ is the most accessible bank for foreigners in Japan, hands down. It operates at over 24,000 post office locations nationwide, so it is available even in rural areas where no other bank has a branch. As of 2026, it accepts foreign nationals with as little as three months of residence — well below the threshold at megabanks.

The catch: the application must be done in person at a post office. There is no online application for foreigners. The banking app and online banking interface are Japanese-only. If you are comfortable with Japanese UI or are willing to use translation tools, this is the fastest path to a working Japanese bank account.

楽天銀行 (Rakuten Bank)

Rakuten Bank is the best option if you want to do everything online without visiting a branch. The application is 100% digital, and Rakuten does not state a minimum residency period for foreign nationals — a valid residence card is the core requirement. Customer support is available in English, which is a genuine differentiator in Japanese online banking.

Rakuten Bank also connects smoothly with services like Wise if you plan to receive international transfers, making it popular with remote workers and engineers receiving foreign-currency salaries. The interface is available in Japanese only, but the initial setup process has English support.

Tier 2 — Moderate requirements (3–6 months in Japan)

住信SBIネット銀行 (SBI Net Bank)

An online bank with no stated minimum residency period for foreign nationals, but a Japanese interface. A good secondary option if you want a second account or if Rakuten’s approval process runs into issues. No branch required — fully online.

SBI新生銀行 (SBI Shinsei Bank)

This is where the stricter rules begin to appear. SBI Shinsei requires that applicants have been in Japan for six months or more and are employed in Japan. It does offer an English banking interface — one of the few that does — which makes it attractive once you hit the eligibility threshold. Not a viable option for new arrivals.

Tier 3 — For established residents (6+ months, employed)

MUFG / Mizuho / SMBC (Megabanks)

Japan’s three major banks are the worst starting point for a newly arrived foreigner. All three require six months or more of residence and proof of Japanese employment. They do not offer English online banking at most branches, and their in-person application process is among the most document-intensive. Their only genuine advantages — brand trust, ATM ubiquity, acceptance for loan applications — only matter once you have been in Japan long enough to qualify.

Start with ゆうちょ or Rakuten. Come back to a megabank after you are settled and employed, if you need one for a specific purpose like a home loan application.

3. Documents you need

The document requirements are consistent across most banks, with some variation. Bring all of these to your first application attempt:

• 在留カード (Residence Card) — the card issued to all non-tourist foreign residents. The validity period on your card matters: if it expires within 3 months, some banks will ask you to renew first.
• マイナンバー (My Number) — see the next section for exactly what form of this you need to bring.
• Passport — required as a second form of ID at most banks.
• Proof of address (住所確認書類) — usually your residence card suffices if your address is registered correctly on it. If not, a utility bill or residence certificate (住民票) from the ward office works.
• Contact information — a Japanese phone number is required at most banks for SMS verification and account setup. Get a SIM card before going to the bank.
• Bank account details for auto-debit setup (任意) — not required at opening, but useful if you plan to set up auto-payments immediately.

Note: Do not attempt to open a bank account before completing your resident registration (住民登録) at the ward office. Without a registered address in Japan on your residence card, banks cannot verify your residency and will reject the application outright. Resident registration comes first — everything else follows.

4. The My Number mistake that trips everyone up

This is where a surprising number of foreigners hit an unexpected wall, even when they have done everything else correctly.

Japan’s My Number system has two distinct forms of documentation, and they are not interchangeable at all banks:

• 通知カード (Tsūchi Card / Notification Card) — a paper card mailed to your registered address when you were first assigned a My Number. It shows your 12-digit My Number but has no photo and no IC chip. This is not the same as the My Number Card.
• マイナンバーカード (My Number Card) — a physical ID card with your photo, IC chip, and 12-digit number. This is what most banks now require, and what you need for services like convenience store document printing and online government procedures.

The problem: many foreigners who arrived before 2021 have only the notification card. Since 2021, an increasing number of banks — including some that were previously flexible — have stopped accepting the paper notification card and require the full physical My Number Card instead. ゆうちょ銀行 still accepts the notification card with your residence card as backup, but this policy can change.

Apply for your マイナンバーカード on Day 1 of your time in Japan. It takes 4–8 weeks to arrive by post. If you apply at the ward office when you do your resident registration, you will have it well before you need it. Do not wait until you need it to start the process. More details: 総務省 マイナンバーカード申請

5. How to open a ゆうちょ銀行 account: step by step

1. Find your nearest post office with a ゆうちょ銀行 counter (not all small post offices have one — Japan Post’s website has a branch finder).
2. Bring: Residence card (在留カード), My Number (card or notification), passport, and a Japanese phone number for SMS verification.
3. Request to open a 通常貯金口座 (regular savings account) — this is the standard personal account and what you want.
4. Fill out the application form at the counter. Staff will guide you through it. If your Japanese is limited, bring a translation app — most post office staff will not speak English.
5. Receive your passbook (通帳) immediately. The passbook is your primary record for ゆうちょ transactions. Your cash card (キャッシュカード) arrives by post within 7–10 business days.
6. Set up the app — ゆうちょ通帳アプリ is Japanese-only but manageable with Google Translate’s camera function if needed.

6. How to open a Rakuten Bank account online: step by step

1. Go to the Rakuten Bank website and select the individual account (個人口座) application.
2. Create a Rakuten ID if you don’t have one. A Japanese email address works; you don’t need a Rakuten shopping account first.
3. Upload your documents: both sides of your residence card and one additional ID (passport photo page). Rakuten accepts digital photos taken with your phone — no scanner needed.
4. Enter your address exactly as it appears on your residence card — any discrepancy will delay the application.
5. Receive your cash card by post (7–14 business days). Your online banking login is active sooner — typically 2–3 business days after document approval.
6. Contact customer support in English if you run into issues during the application — this is one of the few Japanese banks where this is genuinely possible.

7. What to do while waiting for your account

If you are receiving an international salary transfer from a foreign employer — or need to receive money from abroad before your Japanese bank account is ready — a Wise account can bridge the gap effectively.

Wise provides a Japanese yen account with a real bank account number and sort code (口座番号) — the same format that Japanese banks use. This means your employer can wire your salary to your Wise yen account as if it were a domestic Japanese transfer. You can then hold the yen balance, convert, or transfer out at the mid-market exchange rate when you are ready.

This is particularly useful for engineers and remote workers who are paid in a foreign currency by an overseas employer. It also works as a bridge during the 7–14 days you are waiting for your Rakuten or ゆうちょ cash card to arrive by post.

8. Frequently Asked Questions

Can I open a Japanese bank account without a My Number?

No. Since 2016, all Japanese banks are required to collect My Number from account holders. You need either the physical My Number Card or the paper notification card (though an increasing number of banks only accept the physical card). Apply for the physical card as early as possible — it takes 4–8 weeks to arrive.

Do I need a Japanese phone number to open a bank account?

In practice, yes. Most banks use SMS verification during setup, and many require a domestic phone number for account security alerts. Get a Japanese SIM card before attempting to open a bank account. Sakura Mobile ships internationally if you want one before you arrive.

Can I open a bank account at the airport when I arrive?

No. Japanese bank accounts require a registered address in Japan, which means you first need to complete your resident registration (住民登録) at your local ward office after finding accommodation. Resident registration is possible after you have a physical address — not before.

What if my residence card expires soon? Can I still open an account?

If your residence card’s expiry date is less than 3 months away, most banks will ask you to renew it before opening an account, since they need to verify stable ongoing residency. Renew at your local immigration office (or online via the ISA portal for eligible visa categories) before visiting the bank.

Can my employer pay my salary directly to a Wise account?

If your employer pays by domestic Japanese bank transfer (国内振込), they need a Japanese bank account number. Wise does provide a Japanese yen account number that functions like a domestic account for receiving transfers, so yes — this can work as a bridge while you wait for your Japanese bank account to be fully set up. Verify with your employer’s payroll department first.

Can I open multiple Japanese bank accounts?

Technically yes, but opening many accounts rapidly can trigger Anti-Money Laundering review flags. There is no practical need to open more than one or two accounts. One ゆうちょ for day-to-day transactions and one online bank (Rakuten or SBI Shinsei) for transfers and savings is the setup most foreign residents use long-term.

Is my money safe in a Japanese bank?

Yes. Japan’s Deposit Insurance Corporation (預金保険機構) protects deposits up to ¥10,000,000 per depositor per financial institution — equivalent protection to the FDIC in the US or FSCS in the UK. Japanese banks are among the most financially stable in the world.

9. The Bottom Line

The right order matters more than anything else in this process:

1. Complete resident registration (住民登録) at your ward office first — without a registered address, no bank will process your application.
2. Apply for your マイナンバーカード at the same visit — it takes 4–8 weeks to arrive, so start immediately.
3. Get a Japanese SIM card — you will need a Japanese phone number for bank SMS verification.
4. Go to ゆうちょ銀行 for the fastest in-person option, or apply to Rakuten Bank online if you prefer a fully digital setup.
5. Use Wise as a bridge if you are receiving international transfers before your Japanese account is fully live.

The six-month myth has discouraged too many foreigners from even trying. ゆうちょ and Rakuten will both work for most new arrivals. Start there, and move to a megabank later if you genuinely need one.
