Opening a Bank Account in Japan: What Newcomers Need (2026)
Updated: 2026-07-31
Quick answer

Hi, I'm Miya, and I help newcomers get set up in Japan. Opening your first bank account can feel like the big, official one — but it's mostly about bringing the right documents and doing a few things in the right order. Get those two things straight and it's a calm, half-hour errand.
The short version: you'll want your residence card, a form of ID with your address, your personal seal or a signature, a registered Japanese address, and — this is the part people forget — a Japanese phone number. Most banks won't complete an application without a local number to put on the form, so it's worth sorting your mobile first.
Do things in the right order
The single biggest source of frustration is doing steps out of sequence. A bank wants a registered address and a contactable phone number, and both of those depend on earlier errands. So the smooth path looks like this: get your residence card, register your address at the ward office, get a Japanese phone number, then open the bank account.
If you try to open the account before you've registered at the ward office or have a working local number, you'll often be turned away and asked to come back — a wasted trip. A day or two of setup first saves you that round trip.
What to bring
Bring your residence card (在留カード) — this is the key document that proves who you are and that you live here. Bring your passport too, as a backup form of ID. You'll also want proof of your address: your residence card usually carries it once you've registered at the ward office, but having a residence certificate (住民票) on hand doesn't hurt.
Many banks still ask for a personal seal, called a hanko or inkan, though a growing number now accept a signature instead — check before you go so you're not caught out. Finally, have your Japanese phone number ready to write on the form; some banks also ask for a reason for opening the account (work, study, daily living), so keep the answer simple and honest.
Which kind of bank suits a newcomer
There are a few broad options, and the right one depends on how you'll use the account. The large nationwide banks have branches and English support in bigger cities, which helps if you'd like to speak to someone in person. Japan Post Bank has counters in post offices almost everywhere, which is handy outside the big cities.
Online-only banks skip the branch entirely and let you apply from your phone, which many newcomers find the least stressful — but they lean on you having a working Japanese number and address to verify your identity. Whichever you choose, that groundwork is the same, so it pays to have it ready first.
The residency-length question
One thing that trips people up: some banks are cautious about opening an account very soon after you arrive, or if your visa has only a short time left. This isn't personal — it's a standard risk rule. If one bank hesitates, another may be more flexible, and Japan Post Bank and the online banks are often good options for recent arrivals.
Two things quietly help your case: being registered at the ward office (so your address is official) and having a stable, contactable phone number on file. Both signal that you're settled here, which is exactly what the bank wants to see.
After the account is open
You'll usually receive a bankbook (通帳) and later a cash card by mail to your registered address — another reason your address needs to be correct before you start. Set up online or app banking while you're at it; most banks have an app that lets you check your balance, move money, and pay bills from your phone.
That app is also how you'll link your account to the everyday things newcomers set up next — rent, utilities, your mobile bill, and salary from an employer. Nearly all of it runs through the account you just opened, and most of it is managed from your phone.
Why your phone comes first
Look at that whole list and one thread runs through it: a Japanese phone number. It goes on the bank form, it's how the bank reaches you, it's how app banking verifies you, and the online banks need it to open the account at all. Sort your mobile and the rest of the paperwork falls into place.
That's why I get people connected before the bank errand. With Rakuten Mobile you can apply online with just your residence card, and eSIM-capable phones can be running the same day — so you walk into the bank with a working number already on hand. Check current terms on the official page before you apply, and I'll be right here for the mobile part.
