Japan Post Bank Denied Your Account? Why Yucho Refuses Foreigners and What to Do

Updated November 2026 · GaijinHome

Japan Post Bank, usually called Yucho (ゆうちょ銀行), is the bank most newcomers are told to try first. It has branches inside post offices in almost every town, ATMs everywhere, and a reputation for being "easy for foreigners." So when the counter staff hand your residence card back and say they can't open an account, it feels especially unfair. You did what everyone told you to do, and it still didn't work.

If that just happened to you, take a breath. A refusal at Yucho is rarely a permanent judgment about you. In most cases it comes down to timing, a missing detail on your documents, or the way the application was handled at that specific branch. This article walks you through what is really going on and how to turn a "no" into an open account, usually within a few weeks.

What actually happens

Yucho refusals tend to follow a few familiar patterns. Recognising which one you hit is the first step to fixing it:

• Turned away at the post office counter. The staff look at your residence card, check how long you have been in Japan, and tell you to come back later. "Six months" is the phrase many people hear.
• Told you need a Japanese phone number. You gave a foreign number or no number at all, and the application stopped there.
• Sent away because your address doesn't match. The address on your residence card (在留カード) is blank, old, or differs from what you wrote on the form.
• Application accepted, then rejected later. This happens more often with the app-based application. You submit photos of your ID, wait, and receive a notice that the account cannot be opened, with no specific reason.
• Asked lots of questions about purpose and work. Staff ask why you need the account, where you work, and how money will come in. A vague or nervous answer can end the conversation.

Banks in Japan generally don't explain refusals in detail, and post office counter staff often follow internal guidance they can't share. That's frustrating, but it also means the decision is frequently about checklists rather than about you personally.

Why it happens

The residence-length issue

Japanese foreign-exchange rules treat many people who have been in Japan for less than six months as "non-residents" for financial purposes, with exceptions such as people employed by a Japanese company. Banks, including Yucho, often apply a cautious internal version of this. In practice, some branches will open an account for a new arrival who can show employment or school enrolment, while others simply ask everyone under six months to wait. The rule is applied unevenly, which is why one friend gets an account in week two and you get refused in week eight.

Anti-money-laundering checks

Japanese banks have tightened their checks against fraud and money laundering. A recurring concern is accounts being sold or handed over when a foreign resident leaves the country, then used for scams. As a result, banks look closely at people with short remaining periods of stay, unclear income, or no stable address. You are not suspected of anything personally, but you are being screened against a risk profile.

Your period of stay

If your residence card shows only a few months left before expiry, staff may hesitate. A bank account is meant to be long-term, and a near-expiry card raises the question of whether you will still be in Japan next year. Someone with a fresh one- or three-year card usually has an easier time.

Contact and address details

Yucho needs to reach you by phone and mail. A Japanese mobile number and a registered address that matches your residence card are basic requirements at most branches. Foreign numbers, hotel addresses, or a card that still shows no address are common stopping points.

Language and branch experience

Smaller post offices may rarely handle foreign applicants. Staff may be unsure of the procedure for your visa type and choose the safe option: no. Larger branches in cities with many foreign residents tend to be more familiar with the process.

Common mistakes

1. Applying in your first days in Japan. Going to the post office before you have registered your address at city hall almost guarantees a refusal. The residence card must show your address first.
2. Using a foreign phone number. Even if your roaming works, a non-Japanese number usually isn't accepted for the application.
3. Giving a vague reason for the account. Saying "just in case" or "for savings" without context can sound unusual. "To receive my salary from my employer" or "to pay rent and utilities" is clear and normal.
4. Writing your name differently from your card. Your name must match the residence card exactly, including the order and spelling. Mixing in a nickname or a katakana version that isn't on your card causes problems.
5. Giving up after one branch. Many people assume a refusal at one post office applies everywhere. Branch practice varies, and trying a larger branch with your documents in order often succeeds.

Step-by-step fix

1. Find out which reason applies. Politely ask the staff: "What do I need to bring next time?" (次回は何を持ってくればいいですか？ Jikai wa nani o motte kureba ii desu ka?). Even if they won't explain the decision, they will often tell you what's missing.
2. Register your address and update your card. If you haven't already, complete your resident registration at your local city or ward office. Check that the back of your residence card shows your current address. If you've moved, update it within the required period before going back to the bank.
3. Get a Japanese phone number. This is one of the easiest fixes. A prepaid SIM or eSIM with a Japanese number can be set up quickly, even before you have a bank account. [PR] One option is JAPAN&GLOBAL eSIM; just make sure the plan you choose includes a Japanese phone number, not data only.
4. Bring proof of why you are in Japan. An employment contract, a letter from your employer, or a certificate of enrolment from your school helps a lot, especially if you have been in Japan for less than six months. Ask your HR department or international student office for a short letter; many have a template because this situation is so common.
5. Prepare a clear one-line purpose. Practise saying, "I need this account to receive my salary and pay rent." (給料の受け取りと家賃の支払いのためです。 Kyūryō no uketori to yachin no shiharai no tame desu.) Keep it simple and consistent with your documents.
6. Try a larger post office. Choose a central post office in your city rather than a tiny local branch. Going on a weekday morning when it's quieter gives staff more time to process your application carefully.
7. Bring a Japanese-speaking helper if you can. A coworker, school staff member or friend can make the conversation far smoother. Some employers will even arrange this for new hires.
8. If you are under six months, ask about timing. If the branch insists on waiting, ask whether they would accept you with an employment letter now, or what date you should return. Put it in your calendar and come back on that date with the same documents.
9. Use alternatives in the meantime. If Yucho still won't open an account, look at other options: some major banks have English support, some online banks accept applications from foreign residents, and multi-currency services can tide you over for receiving money. Ask your employer whether they can pay salary to a different bank temporarily.

Not having a bank account can also make apartment hunting harder, because rent is usually paid by bank transfer or automatic debit. If you're stuck in that loop, read our guide on renting an apartment without a bank account.

Required documents

Exact requirements can vary by branch and visa type, so treat this as a solid starting list and bring more rather than less:

• Residence card (在留カード) with your current address on the back
• Passport (useful as a second ID, especially if you are new to Japan)
• Japanese mobile phone number
• Certificate of residence (住民票, jūminhyō) issued recently, if your card's address was handwritten or recently changed
• Proof of employment (在職証明書) or employment contract, or a certificate of enrolment (在学証明書) for students
• Student ID or employee ID card, if you have one
• My Number card or notification (マイナンバー) if you have received it
• Personal seal (印鑑, inkan), optional at many branches since a signature is often accepted, but helpful to bring if you have one
• A small amount of cash for an initial deposit, in case the branch asks

City / region differences

Yucho has a single national set of rules, but how branches apply them differs a lot depending on where you are.
