If you are a foreign resident in Japan thinking about starting a business or filing taxes, one of your first practical questions is likely: what kind of bank account do I actually need? Understanding the bank account requirements for business registration and tax filing in Japan as a foreigner can feel overwhelming, especially when documents and procedures are mostly in Japanese. This guide breaks it all down in plain English so you can move forward with confidence.
Why Your Bank Account Matters for Business and Tax Purposes
In Japan, your bank account plays a central role in both registering a business and handling your tax obligations. Tax authorities and business registration offices often require proof of a stable financial presence in Japan. When you file taxes as a self-employed person or business owner, your Japanese bank account is used to receive tax refunds, pay withholding taxes, and demonstrate legitimate income flows. Without a proper account, even basic administrative tasks become much harder.
Do You Need a Business Account or Is a Personal Account Enough?
This is a very common question. The short answer depends on your business structure:
- Sole proprietor (kojin jigyo): A personal bank account is generally acceptable for registering your business and filing taxes. Many freelancers and sole traders in Japan use their personal accounts, especially when starting out.
- Kabushiki Kaisha (KK) or Godo Kaisha (GK) — a registered company: You will almost certainly need a dedicated business bank account in the company's name. This is required when depositing the initial capital during the incorporation process, and banks will ask to see your company registration documents.
As a general rule, keeping business and personal finances separate is strongly recommended regardless of structure. It makes tax filing far simpler and looks more professional to clients and authorities alike.
Bank Account Requirements for Business Registration in Japan
If you are forming a corporation in Japan, you will typically need to open a corporate bank account to deposit the stated capital before completing registration with the Legal Affairs Bureau. Here is a simplified overview of what that process involves:
- Choose a bank that accepts corporate account applications from foreign nationals. Not all banks do, so research this in advance.
- Prepare your company's articles of incorporation (teikan) and other founding documents.
- Deposit the required capital into a personal account first, then have the bank issue a deposit certificate (haraikomi shomei sho) to submit with your registration.
- After registration is complete, open a formal corporate account using your company registration certificate (touki jiko zensho shoumei sho).
Some banks are more foreigner-friendly than others for corporate accounts. This is a guide only — requirements and availability change, so confirm the latest details directly with each bank before applying.
Bank Account Requirements for Tax Filing as a Foreign Resident
For individual tax filing (kakuteishinkoku), you do not necessarily need a special account type. However, you will need a Japanese bank account registered in your name to:
- Receive any tax refund the National Tax Agency (NTA) processes on your behalf.
- Set up direct debit (furikae) for tax payments if you choose that payment method.
- Provide bank details when registering for My Number (your Japanese tax identification number), as financial institutions are increasingly linked to this system.
Your My Number (individual identification number) is separate from your bank account but closely connected to tax filing. Make sure your bank account is linked to your My Number as required by Japanese law, as this is now mandatory for most accounts.
Which Banks Work Best for Foreign Residents Running a Business?
Here is a general comparison of commonly used options. Fees, services and eligibility requirements change over time, so always check the official site for the latest information.
| Bank | Good For | English Support | Notes for Foreign Residents |
|---|---|---|---|
| Japan Post Bank (Yucho) | Sole proprietors, personal accounts | Limited | Often more accessible for newer residents; wide ATM network |
| Rakuten Bank | Online business and personal use | Some English guidance available | Online application; useful for freelancers |
| Sony Bank | International transactions, sole traders | Good English support | Strong multi-currency features; application online |
| SBI Shinsei Bank | Personal and freelance use | English available | Low transfer fees; accessible for foreign residents |
| Major city banks (Mitsubishi UFJ, Sumitomo Mitsui, etc.) | Corporate accounts | Varies by branch | Often require 6+ months of residence; stricter requirements |
What Documents Will You Typically Need?
Whether opening a personal or business account, you will generally need:
- Your residence card (zairyu card) — this is the most important document
- Proof of your Japanese address (your residence card usually covers this)
- A Japanese phone number for verification and contact
- A personal seal (hanko) — required by some banks, though not all
- For corporate accounts: company registration documents and articles of incorporation
- My Number card or notification letter (increasingly required)
Requirements differ by bank, so always confirm the exact list on the bank's official website before your visit or online application.
What If You Cannot Open a Bank Account Yet?
Many foreign residents face a frustrating gap when they first arrive — some traditional banks require around six months of residence before they will open an account. If you need to receive business income or manage money in the meantime, a service like Wise (a licensed e-money provider) can be a practical interim solution. Wise allows you to hold and convert multiple currencies including Japanese yen, and provides local account details that you can share with clients. It is not a substitute for a full Japanese bank account for tax or registration purposes, but it can help you stay financially active while you work towards opening one.
