Opening a Bank Account in Japan for Foreign Residents: The 6-Month Rule, Explained

Sora— research-based comparisons

Published: August 31, 2026

Almost everyone who moves to Japan hears the same warning before they’ve even unpacked: you can’t open a bank account until you’ve been in the country six months. It shows up in relocation guides and forum threads — and it is, at best, half right.

Two different rules hide inside that one piece of advice, from two different places. One is a nationwide legal test for whether currency-control law treats you as a resident at all. The other is a bank’s own screening on how much time is left on your period of stay. Mix them up, and you’ll either give up on an account you were eligible for, or walk into a branch that was always going to turn you away.

Why does every guide say you have to wait six months?

Because it repeats the outcome without the mechanism, and the mechanism is where the useful part lives. “Six months” is not one threshold two systems agree on — it’s one system’s number, casually generalized to describe a different system too.

What Japan’s foreign-exchange law actually says

Article 6 of the Foreign Exchange and Foreign Trade Act defines a resident (kyojūsha) as a natural person with an address or residence inside Japan, and a non-resident (hikyojūsha) as anyone else. Where that’s not obvious, the Act leaves the call to the Minister of Finance.

That’s the situation for most new arrivals, so the working rule lives one document down — a 1980 Ministry of Finance notice interpreting the law. It presumes a foreign national has no address in Japan, with two exceptions treated as residents: someone employed at an office located in Japan, or someone who has been here six months or more. Either condition alone is enough — the detail most write-ups drop. A Japan-based job makes you a resident from your first week, not your sixth month.

The Juminhyo — the resident record required for Japan’s tightened driver’s license conversion rules — reappears below, as a document several banks want alongside a Residence Card.

What the Financial Services Agency expects of banks

The FSA’s supervisory document, most recently dated July 2026, tells examiners what to check in how banks treat foreign customers: whether a bank explains that a Japan-based job or six months here lets a customer switch to a resident account, refuses service over language alone, accepts Roman-letter addresses, or closes accounts without reasonable grounds. It also asks whether banks explain that selling an account is prohibited, and how to close one before returning home.

That’s an examiner’s checklist, not a customer guarantee — it states plainly that it doesn’t require identical treatment everywhere, so one bank’s refusal isn’t automatically unlawful. What it shows is that Japan’s own regulator has told banks, in writing, not to refuse foreign customers reflexively over language.

Japan’s official English guide to opening an account

The FSA also publishes a short leaflet in 17 languages, including English — “Living in Japan: How to Open a Bank Account and Send Money,” revised September 2024 — that most banking guides never mention.

When opening a bank account, you need to bring the following items, for example: Residence card, Passport, Hanko stamp (some financial institution will accept a signature), Employee ID card or student card (If you do not have such a card, please go to the financial institution with someone from your company or school).

financial institutions verify the identity information of customers (e.g., the name, address, period of stay, status of residence, and employment status) at the time of opening an account without exception… You may not be able to open an account or use your account if your identity information is not verified.

— Financial Services Agency, “Living in Japan: How to Open a Bank Account and Send Money” (revised September 2024)

The leaflet is blunt about two moments most guides skip: contact the bank when your address, period of stay or status of residence changes, and contact them again — to close the account — when you leave Japan for good. Giving your account to someone else instead, it warns, can affect your ability to stay in or re-enter Japan. For English questions it lists a dedicated inbox, [email protected], rather than its phone line, which it states is Japanese-only.

How the six-month test shows up on a bank’s own application page

This isn’t just theory — it’s written into several banks’ own English eligibility conditions.

Only residents of Japan (as defined by the Foreign Exchange and Foreign Trade Law) are eligible to apply. If your period of stay (visa) is less than 3 months, please apply after renewing… For customers who have been in Japan for less than 6 months, must prepare proof of employment…

— Seven Bank, online account application for foreign nationals

That “proof of employment” clause is the 1980 notice’s “employed at an office in Japan” exception, translated into a checkout requirement.

The detail behind each row — where it’s most useful — follows below. This guide didn’t verify every bank with an English page: Mitsubishi UFJ Bank and SMBC Trust Bank PRESTIA’s English sites were reachable, but their foreign-resident requirements weren’t checked, and no fees or rates are covered here.

Japan Post Bank: a separate 3-month rule, and an English page stuck in 2022

Japan Post Bank’s rules for foreign nationals holding a Residence Card, in place since 29 July 2019 for anti-money-laundering reasons, are published only in Japanese. If your period of stay expires within three months of applying, it won’t open the account — renew first. An initial period of stay of three months or less with no Residence Card at all rules it out entirely. “Student” and “Technical Intern Training” applicants also submit a student or company ID, which the bank may verify directly with the school or employer; letting a card lapse unreported later freezes withdrawals and transfers.

Search for an English version and you won’t find a current one — the only English page located dates to January 2022 and describes a process since replaced by a “Yucho Procedure App” in Japanese, English, Simplified Chinese and Vietnamese, with no English explainer of its own.

What changed with the new Residence Card on 14 June 2026

From 14 June 2026, Japan began issuing the new Residence Card integrated with the My Number Card. As of August 2026, two banks here can’t yet process it through every channel.

Japan Post Bank can’t currently accept a card issued from that date in its Yucho Procedure App — its workaround is a branch or post office counter instead. Seven Bank went further: a notice dated 8 June 2026 says it stopped accepting the new-format card and Special Permanent Resident Certificate for account opening, address changes and period-of-stay renewals at ATMs, for web-based account opening, and for mail-based account opening (its channel for applicants under 15). Cards issued up to 13 June 2026 still work through those channels. Neither has published a support date — both call it temporary, reason enough to check the current page before assuming either restriction still holds later.

SBI Shinsei Bank: applying by mail only, since July 2026

SBI Shinsei publishes its eligibility in full English:

You must be a resident of Japan. You must have resided in Japan for over 6 months or more, or working in a company with a office located in Japan. This will exclude part-time jobs. You must own a personal Japanese telephone number.

— SBI Shinsei Bank, “Open an account”

That phone-number condition is its own small hurdle for a new arrival — the same kind of number that getting a voice SIM as a resident requires its own identity check to issue.

A June 2026 notice changed how non-Japanese customers apply: from July 2026, still true as of August 2026, SBI Shinsei takes mail-only applications from them — apply online, a paper form arrives by post, mail it back with ID copies, and processing takes about 7 to 10 business days. A Residence Card or Special Permanent Resident Certificate photocopy is the base requirement, plus one more document always needed: a Japanese driver’s license copy, a My Number Card copy, an original Juminhyo issued within six months, or an original utility bill from within six months (a My Number Notification Card isn’t accepted, since it carries no photograph). If the card doesn’t show a “Date of Permission,” the bank separately requires an original Juminhyo showing at least six months of residence in Japan. Where English and Japanese terms disagree, Japanese governs.

Sony Bank and PayPay Bank: Japanese only, built on the same test

Neither publishes an English application, but both still run on the residency test from the 1980 notice.

Sony Bank requires anyone without Japanese nationality to use its mail-based application, not its smartphone-based option, sending a document combination that proves six or more months’ residence — a Residence Card with a recent Juminhyo, for example. A 2025 notice tightened what follows it: from 13 October 2025, failing to confirm an updated Residence Card before your period of stay expires restricts transactions from the day after, distinct from Japan Post Bank’s at-application rule.

PayPay Bank’s FAQ, published 27 May 2026, says non-Japanese nationality alone isn’t a barrier — anyone living in Japan can apply. Verification (age 16+) is a smartphone scan of the Residence Card’s IC chip plus a photo, and the underlying condition is still being a “resident” under the Foreign Exchange and Foreign Trade Law with Japan as sole tax residence. Its English URL returns a 404.

If a Japanese-only branch or phone line is the wall you keep hitting, free public options for learning Japanese is one place to start closing that gap.

A short checklist before you apply

1. Which half of the 6-month test you satisfy — time in Japan, or a Japan-based employer. Either is enough.
2. Your period of stay’s expiry versus the bank’s window — Japan Post Bank needs over three months’ validity left.
3. Which Residence Card format you hold, and whether the bank’s remote channels accept it — check Japan Post Bank and Seven Bank, as of August 2026.
4. Whether English support continues after opening, or only at application — Rakuten Bank and Seven Bank differ here.

Closing the account when you leave Japan

The FSA’s leaflet is direct: contact the bank and close the account when you go back to your country. PayPay Bank’s FAQ repeats the instruction, and the leaflet warns separately that handing your account to someone else instead can affect your ability to stay in or re-enter Japan.

Sony Bank’s Residence Card rule is a related, ongoing duty, not a one-time step. And once money is actually inside a Japanese account, moving it back out runs on its own rules again; our guide to sending money out of Japan covers the reporting threshold and fee layers banks don’t make obvious upfront.

FAQ

What is Japan’s “6-month rule” for opening a bank account? It’s a Ministry of Finance notice interpreting the Foreign Exchange and Foreign Trade Act, not bank policy. It presumes a foreign national is a non-resident unless they’ve been in Japan six months or more, or work at an office located here — either condition makes them a resident immediately. Seven Bank, SBI Shinsei Bank and PayPay Bank each write a version of this test into their own conditions.

What is the “3-month rule,” and is it the same thing? No — it’s a separate rule banks apply to your period of stay, not your residency under the FX law. Japan Post Bank states it plainly: apply within three months of your period of stay’s expiry and it won’t open the account.

Does the new Residence Card affect how I open an account? As of August 2026, yes, at two banks here. Japan Post Bank and Seven Bank both say the card integrated with the My Number Card, issued from 14 June 2026, isn’t yet accepted through every online, app or ATM channel — both call it temporary.

Do I have to close my Japanese bank account when I leave the country? Yes. The FSA states this in its English leaflet, and PayPay Bank’s FAQ repeats it for its own customers. Handing the account to someone else instead is treated seriously — the leaflet warns it can affect your ability to stay in or re-enter Japan.

What to remember

Treat “six months” and “three months” as two separate questions, not one rule with two numbers. Six months asks whether Japanese law counts you as a resident at all, and a Japan-based job answers that immediately. Three months asks whether a specific bank — Japan Post Bank, by its own rule — will accept today’s application, running on your period of stay’s expiry rather than how long you’ve lived here.

Check the Residence Card format separately from both. As of August 2026, the format issued from 14 June 2026 isn’t yet accepted through every remote channel at Japan Post Bank or Seven Bank — worth confirming again later, since both call it temporary.

And plan the end at the same time as the start. Japan’s own regulator tells you, in writing, to close the account before you leave — not to hand it to someone else.

Everything above reflects what the Financial Services Agency, the Ministry of Finance, Seven Bank, Rakuten Bank, Japan Post Bank, SBI Shinsei Bank, Sony Bank and PayPay Bank published as of 13–15 August 2026, plus the statutes cited. Bank policies and temporary restrictions move fastest — check the current page before applying, especially anything marked “as of August 2026” above.
