Foreign Company Entering Japan: Choosing an Entity Type and the Governing Law of Your Contracts

When a foreign company enters the Japanese market, the first things to decide are the choice of entity type and the design of the governing law and dispute resolution for the contracts you will sign locally. The "vessel" you choose determines whether you can conduct business in Japan, who bears liability, and how heavy the tax and procedural burdens are. This guide organizes the differences among the forms, how to choose, contract design, and the regulatory items to check.

Entry into Japan can be organized into three main forms.

It cannot carry out independent business activities. It is limited to preparatory and auxiliary activities such as market research, information gathering, and liaison with the home-country parent. Because it cannot be the party conducting business, it suits an initial information-gathering phase.

A branch can conduct business activities in Japan. However, because a branch is not a separate legal entity, the home-country head office bears the branch's obligations and liabilities. Establishing one requires registration and the appointment of a representative in Japan.

This form establishes a separate legal entity in Japan. Typically, either a stock company (Kabushiki Kaisha, "KK") or a limited liability company (Godo Kaisha, "GK") is used. Incorporating a subsidiary can, in principle, limit the parent company's liability to the subsidiary.

If you set up a subsidiary, a key question is whether to use a KK or a GK.

• Stock company (KK): stronger on credibility and governance. It tends to be more readily recognized by counterparties and in hiring, though the burden of corporate structure and operation is relatively higher
• Limited liability company (GK): simpler to establish and operate. It offers high internal flexibility and easier cost control, though it may be harder to project the same credibility as a KK

The basic axis for choosing is whether you prioritize external credibility and governance or simplicity of formation and operation.

After entering Japan, you will sign local contracts with customers, suppliers, and partners. Here, the key questions are whether Japanese law or foreign law should govern and how to design dispute resolution (jurisdiction or arbitration).

• Choice of governing law: parties may freely choose the governing law of a contract (Act on General Rules for Application of Laws, Article 7). Specifying it in the contract increases predictability
• Absence of agreement: without a governing-law agreement, the law of the most closely connected place applies (Article 8)
• Dispute resolution: decide which courts will hear disputes (jurisdiction) or whether to use arbitration

For the details of governing law, arbitration, and English-contract clauses, see our separate article, "International Business Contracts in Japan: Governing Law, Dispute Resolution & English Contract Basics." The same framework applies to the local contracts you sign upon entering Japan.

Certain inward direct investments may require filings or reports under the Foreign Exchange and Foreign Trade Act (the "Foreign Exchange Act").

• Establishing or acquiring a Japanese company through an equity investment can constitute inward direct investment under the Act
• Depending on the industry and the nature of the transaction, a prior filing may be required

It is important to confirm early, at the design stage of your entry, whether procedures under the Foreign Exchange Act are required.

Depending on the business you conduct, specific licenses or permits may be required. In regulated industries, the feasibility and lead time of obtaining a license can shape the entry plan itself, so this should be checked in parallel with the choice of entity.

Below is a standard flow for a foreign company considering entry into Japan.

• (a) Choose the form: based on the business plan, scope of liability, and tax, choose among a representative office, a branch, and a subsidiary (KK or GK)
• (b) Design the contracts: design the governing law and dispute resolution of your local contracts
• (c) Check the Foreign Exchange Act: confirm whether filings or reports are required as inward direct investment
• (d) Appoint a representative / contact: appoint a representative in Japan for a branch, or a local point of contact
• (e) Check licenses: confirm whether industry-specific licenses are required and the procedures to obtain them

For a foreign company entering Japan, the starting point is to understand the differences among the three types—representative office, branch, and subsidiary (whether business is permitted and where liability rests)—and then choose the form based on the business plan, scope of liability, and tax. Incorporating a subsidiary can limit the parent's liability, and the choice between a KK and a GK is a trade-off between credibility and governance on one hand and simplicity on the other. In parallel, you should address the design of governing law and dispute resolution for local contracts, whether inward direct investment under the Foreign Exchange Act applies, and any industry-specific licenses. Because the optimal entry scheme varies with the combination of business, tax, and regulation, we recommend consulting a professional at an early stage.
