Quick answer: Foreign residents in Japan can open a bank account by showing a residence card with their registered address and a passport, plus a seal or signature depending on the bank. Some banks wait until you have lived in Japan for six months, and the post office bank is a common first choice for newcomers. Requirements vary, so confirm with the bank.

What you need before you go

The central document is the residence card. The post office bank asks customers to present the card, and banks commonly check that it shows your current address, which is why many newcomers complete address registration at the city or ward office first. Bring your passport as well, since staff may ask to see it.

Beyond those two items, requirements differ by bank. Some ask for a National Health Insurance card, a student ID or an employment document, and some ask for a seal or a signature. The most reliable approach is to check the bank's website or call ahead. A short list prepared the day before, with originals and not photocopies, saves a second visit.

Very short stays are a special case. The post office bank states that it does not open accounts for people who have no residence card and whose initial period of stay is three months or less. Visitors on a short stay usually manage with cash, a credit card or an overseas bank card instead. Anyone planning a longer stay should also know that the bank may decline an application, and should arrive with documents that clearly show the period of stay.

The six-month rule

Under foreign exchange rules, a person who has lived in Japan for less than six months is generally treated as a non-resident. The post office bank notes that customers classed as non-residents under the Foreign Exchange Act or the Income Tax Act submit a non-resident notification form, and some banks may handle certain transfers differently for newcomers. Ask the bank how it treats your status and what to do once six months have passed.

In practice, the rule affects how soon different banks will open an account for you. Some banks ask newcomers to wait until about six months after arrival, while others, including the post office bank, may accept residents sooner, although some services may be limited at first. Rules and bank policies change, so ask the bank directly what you can do now and when full services begin.

Post office bank and why newcomers choose it

Japan Post Bank, the post office bank, is a popular first account for foreign residents. Branches are found in nearly every neighborhood, and the bank publishes a page for foreign customers and a smartphone application available in seven languages. You can prepare the application in advance, then take the printed form and your documents to a post office counter.

The bank asks to see your residence card so it can confirm nationality, status and period of stay. Its published guidance says it may not open an account if your period of stay expires within three months of the application date, so renew the stay first if that applies. Account opening can take time, and the passbook or card may arrive by mail later. Important explanations are given in Japanese, so a Japanese-speaking friend is helpful.

Other banks and online banks

Major commercial banks, regional banks and online-only banks also open accounts for residents. Some online banks have Japanese-only websites and may not accept overseas remittances, so read the conditions before relying on one. Branch visits can need an appointment, and banks may take only a limited number of appointments per day, so booking early is sensible.

Choose a bank based on what you will do with it. If your salary will be paid into the account, ask your employer which banks they use. If you plan to receive money from abroad, ask the bank whether it accepts overseas remittances and what fees apply. A convenient branch or ATM near home or work matters more than an impressive list of services. If you are unsure, start with a single everyday account and add others later once you know how you use money in Japan, including how you pay rent and utilities.

Seal or signature

Japanese bank forms traditionally rely on a personal seal (inkan or hanko), but many banks accept a signature from foreign residents. Policies differ. Some banks require a seal, while others accept either a seal or a signature. If you have a seal, bringing it avoids problems. Ask the bank whether a seal is needed before buying one.

Keep your seal and passbook in separate places and never lend them to anyone. Use the same spelling of your name on every form as on your residence card, so the bank record matches your identity documents. If your name appears in more than one script on your card, ask the staff how it should be entered.

Using ATMs and managing the account

Counters at most banks are open on weekday daytime hours, while ATMs are available early, late and on weekends, though fees may apply outside normal hours. Post office bank cards work at post office ATMs and at convenience-store ATMs, which makes cash withdrawals easy in most towns. A cash card or passbook is often sent by post and can take a week or two to arrive, so ask the bank for its timing.

Banks send many notices in Japanese. Use a translation tool or ask a colleague, and open mail from the bank promptly. Check whether the bank offers an online banking service in English. Keep some cash on hand when starting out, since not every shop accepts cards.

Keeping the account in good order

Tell the bank when you renew your residence card or change your address, and bring the updated card. Banks may restrict transactions if their records are out of date. Close your accounts before leaving Japan permanently, because accounts left unused can be difficult to manage from abroad.

Never sell, lend or give away your bank account, passbook or cash card to another person. The post office bank states that selling or transferring them to someone else is a crime. This guide shares general information; rules change, so confirm details with the official agency or provider before you act.
