Documents Needed to Open a Japanese Business Bank Account

Why Opening a Bank Account in Japan Is Difficult

Opening a corporate bank account in Japan is one of the most challenging steps for newly registered companies, particularly those with foreign ownership. Japanese banks operate under strict anti-money laundering (AML) regulations and have historically been conservative in onboarding new corporate clients.

Banks will scrutinize the legitimacy of your business, the background of the representative director, the source of capital, and the nature of your planned transactions. Foreign-owned companies face additional scrutiny because banks have limited ability to verify overseas business histories and references.

Rejection is common, especially at major banks in the first six months after incorporation. This does not mean your company has a problem — it simply reflects the conservative approach of Japanese banking. Being well-prepared with a complete set of documents significantly improves your chances.

Required Documents

The following documents are required by virtually all Japanese banks when opening a corporate account. Having every document ready before your appointment dramatically increases your chances of approval.

• Company Registry Certificate (履歴事項全部証明書)
  The single most important document. Must be a recent original (issued within 3 months). Proves your company is legally registered and shows the company name, address, directors, capital, and purpose. Every bank requires this without exception.
• Articles of Incorporation (定款)
  Your company's founding document. Banks review this to understand your governance structure, business purpose, and any restrictions on the representative director's authority. Bring the original or a certified copy.
• Corporate Seal Certificate (印鑑証明書)
  Certifies that your registered company seal is genuine. Must also be recent (within 3 months). Required for all banking transactions in Japan, as contracts and applications are executed with the company seal rather than signatures.
• Representative Director's Identification
  For foreign nationals, this means a residence card (zairyu card) or passport. The bank will verify the representative's identity and residential status in Japan. Some banks may also request identification for all directors, not just the representative.
• Business Plan
  Not all banks explicitly require this, but having a clear, written business plan significantly improves your chances. Include a description of your products or services, target market, expected revenue timeline, and client information. Even a few pages can make a difference.
• Office Lease Agreement
  Proof that your company has a physical office. Banks are wary of companies that operate solely from virtual offices. If you use a co-working space, bring the membership agreement and confirm it includes a registered address.
• Company Seal (実印)
  You will need to bring your registered company seal to the bank appointment. The seal will be registered with the bank for use on all future transactions. Some banks also require a separate bank transaction seal (ginko in / 銀行印).

Bank-by-Bank Guide

Major Banks (Mega Banks)

MUFG (三菱UFJ銀行), SMBC (三井住友銀行), Mizuho (みずほ銀行)

The three mega banks are the most prestigious but also the most difficult for new companies to access. They typically prefer companies that have been operating for at least six months and have established business activity. Foreign-owned companies with limited history in Japan are frequently rejected.

If your business involves international transactions, these banks offer the best infrastructure for foreign currency accounts and international wire transfers. However, you may need to approach them after your company has built a track record with a smaller bank first.

Regional Banks and Credit Unions (Shinkin Banks)

Regional banks and shinkin banks (credit unions) are generally more accessible to newly registered companies. They are more relationship-oriented and may be willing to work with you if you have a physical office in their service area. Examples include Yokohama Bank, Chiba Bank, Fukuoka Bank, and local shinkin banks.

The trade-off is a smaller branch and ATM network and more limited international banking capabilities. However, once you have an account at a regional bank, opening a second account at a mega bank later becomes much easier.

Online Banks

GMO Aozora Net Bank, PayPay Bank, Rakuten Bank

Online banks have become increasingly popular with startups and foreign-owned companies. They offer simpler application processes, lower fees, and English-language support in some cases. GMO Aozora Net Bank in particular has positioned itself as startup-friendly and often accepts newly registered companies that mega banks decline.

The application process is typically handled online or by mail, which can be more convenient than in-person visits. However, some online banks have limited cash deposit capabilities and may not support all types of international transactions.

Tips for Approval

• Have a physical office. This is perhaps the single biggest factor. Banks strongly prefer companies with a real office address over virtual offices. If you use a co-working space, ensure it provides a verifiable registered address.
• Prepare a solid business plan. Even if the bank does not explicitly request one, having a well-structured business plan demonstrates legitimacy. Include concrete details about your clients, services, and revenue model.
• Start with a regional or online bank. Rather than starting at a mega bank and risking rejection, build a banking history with a more accessible institution first. You can add a mega bank account later once your company has 6–12 months of transaction history.
• Bring a Japanese speaker. Bank staff at the branch level rarely speak English. Having a Japanese-speaking representative or interpreter at the appointment ensures clear communication and shows the bank you are serious about operating in Japan.
• Ensure all documents are current. Registry certificates and seal certificates must typically be within 3 months of issue. Bring originals, not copies.
• Apply at the branch nearest your registered office. Banks prefer to serve companies in their local area. Visit the branch closest to your company's registered address.
• Have your company website live. Banks will often search for your company online. A professional website with clear information about your business helps build credibility.

Timeline

After submitting your application and all required documents, the review process typically takes 2 to 4 weeks. Some online banks can process applications faster, within 1 to 2 weeks. Mega banks may take longer, particularly if they request additional documentation.

If your application is rejected, you can reapply after a few months. In the meantime, consider building your business activity and documentation to strengthen your next application. There is no formal waiting period between applications, but applying to the same bank repeatedly in a short timeframe is unlikely to yield a different result.
