How to Open a Bank Account in Japan as a Foreign Worker — A Step-by-Step Guide for SSW Workers

Opening a bank account is one of the first practical challenges every new foreign worker in Japan faces. Without an account, you can't receive your salary, pay rent, set up phone service, or send money home. Yet Japan's banking laws make it surprisingly difficult to open most types of accounts in your first 6 months in the country.

This guide explains exactly how to navigate the system: which bank to start with on Day 1, what documents you need, the famous "6-month rule", how to add an internet bank later for better fees, and how your employer or registered support organization should help. After reading this, you'll have a clear plan for getting fully banked in Japan.

Why It's Hard — The 6-Month Rule

Most banks in Japan will refuse to open an account for a foreign resident who has been in Japan for less than 6 months. This is not bank-specific discrimination — it's a measure under the Act on Prevention of Transfer of Criminal Proceeds, designed to prevent money laundering through accounts that might be used and abandoned by short-term residents.

Banks check your length of residence by looking at the issue date on your Residence Card. If less than 6 months have passed since your card was issued, most major banks (MUFG, SMBC, Mizuho, Resona) will turn you away.

The exception: Japan Post Bank has different rules and can open an account for new foreign residents from Day 1, as long as you have your Residence Card. This is why Yucho is the standard "first bank" for new SSW workers in Japan.

Start with Yucho (Japan Post Bank) on Day 1

Japan Post Bank is operated through Japan's nationwide post office network and has approximately 24,000 ATMs and post office branches across the country. For new SSW workers, it has several advantages:

No 6-month wait — opens accounts for new arrivals with valid Residence Card
Nationwide branches — even small towns have a post office that can handle bank business
Free ATM withdrawals at any Yucho ATM, anywhere in Japan
Basic English/multilingual support at major post offices
Acceptable for salary deposits at most employers
Acceptable for utility payments and rent

Documents You Need

Bring all of the following to the post office. If anything is missing, you'll have to come back another day.

Residence Card — both sides; address must be current and registered with your local ward office
Passport
My Number Card or Notification Card — required for tax and AML compliance. If you don't have one yet, you can sometimes open an account first and add the My Number later.
Personal seal — preferred. Signature is increasingly accepted at post offices, but having a personal seal makes everything smoother. You can get a basic name seal made at any seal shop or hardware store for ¥500–¥3,000.
Proof of address — the address on your Residence Card serves this purpose if it's current
Phone number — helpful but not always required. If you don't have a Japanese phone number yet, you can sometimes still open the account and add the phone later.

Make sure your address is registered first. Within 14 days of arriving at your residence, you must register your address at your local ward office. Until you do this, your Residence Card will not show your current address, and the bank will refuse to open the account. The address registration is free and takes about 30 minutes.

Step-by-Step: Opening a Yucho Account

Register your address at the ward office

Take your Residence Card and passport to the local ward office. The ward office staff will print your new address on the back of your Residence Card. This is required before any bank will open an account for you. While you're there, you can also apply for your My Number if you don't have one.

Get a personal seal made

Go to any seal shop or stationery store. A basic seal with your name in katakana costs ¥500–¥3,000. Standard size is 10.5mm or 13.5mm. Bring it everywhere with you, including the post office.

Visit a major post office

Find a "central" post office or one with banking services in your area. Smaller branches may have limited bank-related services. Bring all your documents and your seal. Best to go in the morning on a weekday to allow time.

Request a savings account

Tell the staff: "ゆうちょの口座を開きたい" (I want to open a Yucho account). They'll give you the application form. The form is in Japanese; staff at major branches can usually help with basic English. If you have trouble, ask if multilingual staff are available, or bring a Japanese-speaking friend.

Complete the application form

You'll fill in: your name (in katakana), date of birth, address (matches your Residence Card), phone number, occupation, employer name. Sign and stamp with your seal where indicated.

Receive your bankbook and cash card

The bankbook is given immediately. The cash card is mailed to your registered address within 1–2 weeks. You can use the bankbook for deposits, withdrawals, and balance checks at any post office or Yucho ATM. The cash card lets you use ATMs without the bookbook.

After 6 Months: Adding a Better Bank

After you've been in Japan for 6 months, the rest of the banking world opens up. Adding a second bank account — ideally an internet bank — gives you significant advantages:

Better online banking apps with English/multilingual interfaces
Lower remittance fees for sending money to your home country
Higher interest rates on savings (still low overall, but better than Yucho)
Better integration with payment apps like PayPay, LINE Pay
24/7 customer service at many internet banks

You can keep your Yucho account active — many people use Yucho for salary deposit and a second bank for daily use, savings, and remittances.

Bank Comparison for Foreign Workers

Bank	Best For	Notes
Yucho	First account, nationwide branches	No 6-month wait; basic services; widely accepted
Shinsei Bank	English service, foreigners	PowerFlex account; multilingual app; good for remittances
SMBC	Multilingual customer service	Major bank network; multilingual phone support; some English staff
Sony Bank	Multi-currency, low remittance fees	Internet bank; multi-currency accounts; cross-border transfer features
Rakuten Bank	Online services, payment integration	Internet bank; integrates with Rakuten ecosystem; competitive fees
SBI Sumishin Net Bank	Low fees, savings focus	Internet bank; very low ATM and transfer fees; basic English support limited
MUFG Bank	Largest branch network	Major bank; comprehensive services; mostly Japanese-only support
Mizuho Bank	Major bank, branch access	Similar to MUFG; mostly Japanese-only support

Common SSW worker setup: Yucho (salary deposit + emergency cash) + Sony Bank or Shinsei (savings + remittances home). This combination gives you nationwide branch access AND low fees for sending money to your home country.

Online Banking and ATM Tips

Yucho ATM: Free withdrawals from your Yucho account 24/7. Available at every post office and many convenience stores.
7-Eleven ATM (Seven Bank): Works with most Japanese cards. English menu available. Often free with major banks.
Lawson and FamilyMart ATMs: Lower fees than convenience store norms. English menu.
Internet banking activation: After opening any account, ask the bank to enable internet banking. Many banks now allow this online via your bank app.
Mobile apps: Most major banks have smartphone apps. Yucho's app is Japanese only; Sony Bank, Rakuten, Shinsei have English/multilingual apps.

Employer / Support Organization Help

Under SSW Type 1 rules, your employer or registered support organization has a legal obligation to provide life support for foreign workers, including help with bank account setup. Specifically:

Pre-arrival orientation should mention banking requirements
Post-arrival life orientation should include bank account opening assistance
The support organization should be able to refer you to a bank, accompany you, and help with paperwork
Some employers have arrangements with specific local banks for fast-track foreign worker accounts

If your employer or support organization refuses to help with this basic life support, that's a warning sign about their overall quality. By law, they must assist you. Speak up — or seek a new employer.

Common Issues and Fixes

Issue: "We can't open the account because you've been in Japan less than 6 months"

Fix: Go to a post office and open a Yucho account. They don't have the 6-month rule. After 6 months, return to the bank that refused you.

Issue: "Your address on your Residence Card doesn't match"

Fix: Visit your local ward office and register your current address. Bring your Residence Card; they'll print the updated address on the back.

Issue: "We need a Japanese phone number"

Fix: Some banks require this; others don't. Yucho often does not. If you don't have a Japanese phone yet, your employer's address can sometimes be used as a contact, or open the account first and add the phone later.

Issue: "We need My Number"

Fix: Apply for My Number at the ward office. The notification card arrives by mail in 2–4 weeks. The physical My Number Card is optional but useful.

Issue: "We need a personal seal"

Fix: Get one made at any seal shop. Basic name seal: ¥500–¥3,000.

Frequently Asked Questions

Japan's banking laws restrict most banks from opening accounts for residents who have been in Japan for less than 6 months. This is a measure under the Act on Prevention of Transfer of Criminal Proceeds, designed to prevent money laundering. The exception is Japan Post Bank, which can open an account for new arrivals as soon as you have your Residence Card. Many SSW workers therefore start with a Yucho account and add a regular bank account after 6 months in Japan.

Typically required: (1) Residence Card — both sides, (2) Passport, (3) My Number Card or Notification Card, (4) Personal seal — though signature is increasingly accepted, (5) Proof of address (residence card serves this purpose if address is current), (6) For some banks: phone number registered to your address (which may itself require a Japanese bank account — a chicken-and-egg problem solved by starting with Yucho). Bring your work-related documents (employment contract, payslips) — some banks ask to confirm your employment.

For most SSW workers, Yucho (Japan Post Bank) is the best first account because of no 6-month wait, nationwide branches, and basic English/multilingual paperwork. After 6 months, adding an internet bank like Sony Bank, Rakuten Bank, or SBI Sumishin Net Bank gives you better online banking, lower remittance fees, and multilingual app interfaces. Shinsei Bank's PowerFlex account is particularly foreigner-friendly. SMBC has multilingual customer service. Choose based on whether you prioritize: branch access (Yucho, MUFG, SMBC), low remittance fees (Sony, Rakuten, SBI), or English service (Shinsei, SMBC).

Yes, and good employers do. Many SSW employers and registered support organizations actively assist new workers with bank account opening as part of life support services. They can call the bank in advance, accompany you to the branch, help with paperwork in Japanese, and recommend specific banks based on local convenience. Ask your employer or support organization on Day 1 — don't wait. If they refuse to help with this basic life support, that's a warning sign about the employer's quality.

Summary

Critical first step: Register your address at the local ward office within 14 days of arrival

Banking in Japan is challenging for new arrivals, but with the right plan it's entirely manageable. Start with Yucho on Day 1 to get banked immediately, then add a better bank after 6 months for online services and lower fees. Get help from your employer or support organization — they have a legal duty to assist. With a solid banking setup, you can focus on your work, save for the future, and send money home efficiently.
