If you have a Japanese bank account and you're worried about what happens when you stop using it — whether you're travelling, between jobs, or simply not making regular transactions — you're not alone. Understanding Japanese bank account inactivity rules for foreigners can save you from losing access to your money or having your account quietly closed without warning. This guide walks you through what you need to know and, more importantly, what you can do about it.
What Does "Dormant Account" Mean in Japan?
In Japan, a bank account that has had no transactions for an extended period is classified as a dormant account (休眠口座, kyūmin kōza). Once an account reaches dormant status, the bank may restrict your access to it, charge maintenance fees, or in some cases, transfer the funds to the government under Japan's Dormant Deposits Act.
This applies to all account holders — Japanese nationals and foreign residents alike. However, as a foreigner, you may face additional complications, such as a change in your visa status, a change of address you forgot to report, or simply not using the account because you left Japan temporarily.
How Long Before a Japanese Bank Account Becomes Dormant?
The exact dormancy timeline varies by bank, so always confirm directly with your bank. As a general guide:
- Most major banks: Accounts with no transactions for approximately 2 years may begin to have restrictions applied.
- Japan Post Bank (Yucho Bank): Accounts with no transactions for around 10 years can be transferred to the government under the Dormant Deposits Act. However, access restrictions and fees may apply well before that point.
- Online banks (such as Rakuten Bank, Sony Bank, SBI Shinsei Bank): Policies differ — some are more lenient, but they may still charge inactivity fees or close accounts after a set period.
⚠️ These are general guidelines. Bank policies change, and the specific timeline for your account depends on the bank and account type. Always check the latest rules directly on your bank's official website or by contacting their customer support.
What Happens to the Money in a Dormant Account?
Under Japan's Dormant Deposits Act (休眠預金等活用法), introduced in 2019, funds in accounts that have been inactive for 10 years are transferred to a designated government body and redistributed for public benefit purposes. Importantly, you do not automatically lose your money — you can still claim it back through the bank, even after the transfer. However, the process can be time-consuming and may require extra documentation.
Before the 10-year mark, most banks will notify you by post before taking action. This is why it is critical to keep your registered address up to date — if the bank cannot reach you, notifications go nowhere.
Risks Specific to Foreign Residents in Japan
As a foreign resident, there are a few extra situations that can put your account at risk:
- Leaving Japan: If your visa expires or you return to your home country, you may stop using the account — and the bank may not be able to contact you.
- Address changes: Moving without updating your bank can mean missed dormancy warnings.
- Visa status changes: Some banks require that your residence card (zairyu card) details remain current in their records. An expired card on file can cause complications.
- Language barrier: Dormancy notices are typically sent in Japanese. If you don't read Japanese, you may miss important letters.
How to Keep Your Japanese Bank Account Active: Practical Steps
The good news is that preventing dormancy is straightforward. Here is what you can do:
- Make at least one transaction per year — even a small ATM withdrawal, a transfer, or a deposit counts. Check your bank's policy on what qualifies as a "transaction."
- Keep your address updated — whenever you move, notify your bank promptly. Most banks let you update your address online, by ATM, or in-branch.
- Update your residence card details — when you renew your zairyu card, update the information with your bank as well.
- Register for online banking — logging into your online banking account may or may not count as a transaction, but it keeps you aware of any notices. Check with your specific bank.
- Set up a small automatic payment — linking a regular subscription or utility bill to your account ensures regular activity without effort.
- Check your account periodically — even if you are overseas, log in to your online banking to review your account status.

This table is a general guide only. Always confirm the current policy directly with your bank, as rules are updated regularly.
What If You Can't Open a Japanese Bank Account Yet?
If you are new to Japan and haven't yet been able to open a traditional bank account — many banks ask for around 6 months of residency — you still have practical options. Wise is a licensed e-money service that lets you receive, hold, and convert Japanese yen and other currencies with your own account details. It's a useful interim solution while you build up your residency history. Japan Post Bank (Yucho) and some online banks such as Rakuten Bank are generally considered more accessible for new arrivals, often with lower residency requirements.
Summary: Staying on Top of Your Account as a Foreign Resident
Japanese bank account inactivity rules for foreigners are manageable once you know what to watch for. The key points to remember are:
- Dormancy timelines vary by bank — confirm the specific rules with your bank directly.
- Keep your address and residence card details up to date with your bank at all times.
- Make at least one transaction per year to keep your account active.
- If you leave Japan, stay connected to your account online and check for notices.
- Dormant funds can be reclaimed even after government transfer, but it takes effort.
Living in Japan as a foreigner comes with a learning curve, but managing your bank account doesn't have to be stressful. A small amount of routine attention — one transaction, one address update — goes a long way. You've already taken the right step by looking into this now.
