Do You Need a Physical Address for a Subsidiary in Japan?

Japanese law mandates all subsidiaries to maintain a registered physical address for legal compliance and official communications. This address appears in incorporation documents and enhances business credibility.

Companies without permanent offices can use virtual offices, shared workspaces, or registered agent services to fulfill this requirement. While virtual solutions offer cost savings, leasing actual office space may be preferable for long-term operations or local hiring.

The address must be capable of receiving government correspondence and tax notices. Choosing an appropriate solution depends on business needs, budget, and growth plans in Japan.

Staffing requires compliance with local labor laws, including mandatory social insurance enrollment for full-time employees.

How to Open a Business Bank Account for a Subsidiary in Japan

Opening a corporate bank account is a critical step when setting up a subsidiary company in Japan. The process can be challenging for foreign businesses, but proper preparation ensures success. Here’s what you need to know about how to establish a subsidiary company in Japan and open a corporate bank account:

Steps to Open a Corporate Bank Account

  2. Prepare Documents: Provide company registration, incorporation papers, seal certificate, director IDs, and address proof.
  3. Schedule Appointment: Though some banks accept authorized proxies, directors must attend in-person meetings.
  4. Submit Forms: Complete account opening, signature/seal, and AML declaration forms.
  5. Deposit Funds: Activate the account with an initial deposit (¥100,000–500,000).

By following these steps, you can establish the financial foundation needed to operate your subsidiary in Japan. The process requires patience and attention to detail, but proper preparation leads to successful account opening.

Foreign-owned subsidiaries should consider bilingual agreements that align with global policies while meeting Japanese legal requirements, particularly for cross-border tax and IP matters.

Though not universally required, well-drafted operating documents provide essential operational clarity and legal protection, especially for GKs or businesses needing precise internal controls. Proper governance setup ensures compliance and smoother subsidiary management.

– No access to tax incentives
– Profits taxed only in Japan
– Eligible for tax credits and deductions (e.g., R&D incentives)
Regulatory RequirementsFewer compliance obligations (no annual shareholder meetings)Stricter governance (e.g., audits, annual filings, shareholder meetings)
Business CredibilityPerceived as less established (may affect contracts with Japanese partners)Higher credibility (preferred for long-term operations and local partnerships)
Operational FlexibilityLimited autonomy (parent controls all decisions)Greater independence (can set local management and strategies)
Exit ProcessEasier to close (no formal dissolution required)Complex dissolution (requires shareholder approval and liquidation procedures)

When to Choose a Branch

  • Short-term projects or market testing
  • Lower upfront costs and faster setup
