Company Registration in Japan

Japan offers a structured market for international companies entering Asia, but establishing a local presence requires careful consideration of the legal form, ownership structure, business activities and registration procedures. Foreign companies generally enter Japan through a representative office, branch office or subsidiary company, depending on the nature and scale of their intended activities.

A representative office is generally used for market research and liaison activities and cannot normally conduct sales. A branch office can conduct business but remains part of the foreign parent company. A subsidiary is a separate Japanese legal entity and can be established in forms such as a Kabushiki-Kaisha (K.K.) or Godo-Kaisha (G.K.).

For foreign investors planning commercial operations, selecting the appropriate structure is therefore one of the first decisions in company registration in Japan.

Key Highlights of Company Registration in Japan

• Foreign companies can establish a representative office, branch or subsidiary depending on their activities.

• K.K. and G.K. are important subsidiary structures available under Japan’s Companies Act.

• A branch office must have at least one representative with an address in and residence in Japan.

• A representative director of a K.K. does not have the same Japan-residency requirement applicable to a branch representative.

• Subsidiaries and branches conducting business generally require commercial registration with the Legal Affairs Bureau.

• Foreign investment notifications may apply depending on the proposed business activity.

• Registration is followed by tax and other regulatory notifications applicable to the company and its activities.

Choosing the Right Structure for Japan Company Formation

The legal structure should be selected according to the investor’s intended operations rather than simply based on the ease of registration.

• Representative Office: Appropriate for preliminary market research, information gathering and liaison activities. It cannot generally conduct sales or other revenue-generating commercial operations.

• Branch Office: A branch allows a foreign company to conduct business in Japan without establishing a separate Japanese corporation. However, the branch does not have an independent corporate identity from the foreign parent, and the parent generally bears responsibility for its obligations.

• Subsidiary Company: A subsidiary is a separate legal entity from the overseas parent. A foreign company can establish a K.K., G.K. or another permitted corporate form under the Companies Act.

The structure chosen can affect governance, liability, banking, taxation, documentation and ongoing compliance.

Japanese Subsidiary Setup: K.K. or G.K.?

Two commonly considered forms for a Japanese subsidiary setup are the K.K. and G.K.

A K.K., or Kabushiki-Kaisha, is a joint-stock corporation. It is often considered where the investor wants a conventional corporate structure based on shares, directors and shareholder governance.

A G.K., or Godo-Kaisha, is a limited liability company. It provides greater flexibility in internal governance through its articles of incorporation and does not have the same financial-statement publication requirements applicable to a K.K.

Both structures provide limited liability within the applicable legal framework. The appropriate choice depends on the intended ownership arrangement, management structure, financing plans and business objectives.

Requirements for Japan Business Incorporation

Before starting Japan business incorporation, the proposed company’s basic particulars need to be determined.

Key information generally includes:

• Proposed company name

• Registered office address in Japan

• Business objectives and activities

• Capital and contribution structure

• Shareholders or members

• Directors or other responsible officers

• Governance arrangements

• Financial year

• Articles of incorporation

• Information concerning foreign shareholders or the overseas parent company

Business objectives require particular attention because they define the activities that the company is established to undertake. The objectives should therefore reflect the actual and planned scope of operations.

Documents Required for Foreign Investors

The documentation depends on whether the applicant is establishing a subsidiary or registering a branch and on the circumstances of the foreign shareholder.

For a foreign-owned subsidiary, documents may include:

• Identification and address details of shareholders and directors

• Corporate registration documents of the foreign shareholder

• Articles or constitutional documents of the foreign parent

• Evidence of authority of the foreign representative

• Signature or signature certificate documents

• Affidavits or equivalent documents where required

• Japanese translations of foreign-language documents

For a branch, documents establishing the existence and corporate particulars of the foreign parent are important because the branch is legally connected to that foreign company. Documents issued outside Japan may require appropriate certification, notarization or other authentication depending on the document and jurisdiction.

Register a Company in Japan: Registration Process

The process to register a company in Japan normally involves several stages.

•  Determine the proposed business activities and appropriate legal structure.
•  Decide the company name, registered office and corporate particulars.
•  Prepare the articles of incorporation and other establishment documents.
• Collect and prepare documents relating to foreign shareholders or the overseas parent company.
• Complete required authentication procedures for documents and articles, where applicable.
• Complete the capital contribution procedures for the selected entity.
• Submit the incorporation registration application to the competent Legal Affairs Bureau.
• Obtain the company’s registered information and corporate certificates after registration.
• Complete applicable tax, investment and other regulatory notifications.

For a branch, the registered information includes matters such as the branch address, representative in Japan, establishment date and other prescribed details. The branch may begin business operations after the establishment has been registered with the Legal Affairs Bureau.

Foreign Company Registration in Japan

A foreign company intending to conduct continuous commercial activities in Japan may establish a branch or subsidiary depending on its objectives.

For foreign company registration in Japan through a branch, the foreign parent remains the underlying corporate entity. At least one representative in Japan must have an address in Japan and be resident there. The representative does not necessarily need to be a Japanese citizen.

A subsidiary is different because it creates a separate Japanese corporation. JETRO confirms that a non-resident person can be a representative of a subsidiary, while the Japan-residency requirement applies specifically to branch representatives.

Foreign Investment and Business Activity Requirements

Company registration is not the only consideration for an overseas investor entering Japan. Certain investments and activities may be subject to notification requirements under Japan’s foreign exchange and foreign trade regulations.

Depending on the industry and proposed activity, prior notification to the Bank of Japan may be required. Other investments may be subject to post-establishment reporting requirements.

Additional licences, permits or approvals can also apply to regulated sectors. Therefore, the proposed business activity should be reviewed before the registration structure is finalized rather than treating incorporation as the only regulatory requirement. JETRO’s current guidance was updated following legal revisions during fiscal year 2025.

Benefits of Company Registration in Japan

• Creates a formal Japanese presence for international companies.

• A subsidiary provides a separate legal identity from its foreign parent.

• Supports local commercial contracts and customer relationships.

• Provides a suitable structure for establishing local operations and hiring employees.

• Can support local banking and operational arrangements.

• Allows foreign investors to select between different corporate structures according to their requirements.

• Provides a structured foundation for long-term expansion in the Japanese market.

Tax and Post-Registration Requirements

Completing incorporation does not end the compliance process. After establishment, the company may need to submit notifications to national, prefectural and municipal tax authorities.

JETRO states that a subsidiary’s incorporation notification is generally filed within two months of incorporation. Where the company establishes an office that pays salaries, a separate notification generally applies within one month of establishment. Other filings depend on the company’s circumstances.

If employees are hired, labour-related obligations can also arise. Businesses becoming subject to Japan’s Labour Standards Act must comply with applicable reporting requirements, while labour insurance procedures arise when the business employs workers.

A corporate bank account is another separate operational step. Banks may review the company’s registration records, ownership, business activities, management information and supporting documents before deciding whether to open an account.

How Long Does Company Registration in Japan Take?

The overall timeline depends on the structure, document preparation, authentication requirements and registration process.

JETRO’s general guidance indicates that a branch can take around one month after the information to be registered has been determined, while establishing a subsidiary may take around two months after the particulars of the company have been finalized. These are general reference periods rather than guaranteed completion times.

Foreign-document preparation can also influence the overall timeline, particularly where documents require certification, authentication or Japanese translation.
