Four routes, four different purposes
“Set up a company in Japan” can refer to several different legal forms. JETRO distinguishes a representative office, branch office and Japanese subsidiary. A subsidiary may be organised as a Kabushiki Kaisha (KK) or Godo Kaisha (GK). These choices are not interchangeable.
Quick comparison
| Structure | Separate Japanese legal entity? | Key consideration |
|---|---|---|
| KK (Kabushiki Kaisha) | Yes | Share-based company; formal corporate governance |
| GK (Godo Kaisha) | Yes | More flexible internal governance for members |
| Branch office | No | Overseas parent generally bears responsibility for branch obligations |
| Representative office | No | Preparatory activity; generally cannot sell products or services |
These are simplified distinctions. JETRO also explains how transferability of ownership, directors and public offers differ by legal form.
When KK may be attractive
- A share-based structure is important for future investors or shareholders.
- The business plans to use governance familiar to Japanese corporate counterparts.
- The owners accept the more formal company administration.
A KK is not automatically the best or cheapest structure for every founder; operational priorities come first.
When GK may be attractive
- The ownership group values flexible internal arrangements.
- There is no immediate need to issue shares through a KK structure.
- The founders want to consider a different governance and setup cost profile.
A GK is a Japanese corporation, not the same legal product as a U.S. LLC for tax purposes. Discuss cross-border consequences with appropriate tax specialists.
When a branch may be more suitable
An overseas corporation expanding directly may use a registered Japanese branch. JETRO explains that the branch is part of the same foreign legal entity, and its commitments generally flow back to the parent. It is not a stand-alone Japanese subsidiary.
A representative office has limits
A representative office may support market research or promotion, but JETRO says it cannot engage in sales activities and ordinarily cannot hold a bank account or lease premises in its own name. Businesses that plan to start commercial operations should not confuse this with a registered branch.
What about a visa or minimum capital?
Commercial registration and the Business Manager residence status have different rules. JETRO notes that some legal forms can be established with very small capital, while the updated Business Manager immigration framework has materially different financial and staffing criteria. The right setup depends on whether someone also needs residence permission.
