Japan entry guide 2026: A practical roadmap for foreign companies setting up in Japan

The first and most important decision for a foreign company is determining the form of presence it intends to establish in Japan. The chosen structure should align with the company's objectives, proposed business activities, funding strategy, and long-term operational plans.

Depending on its requirements, a foreign company may establish one of three principal structures:

Kabushiki Kaisha (KK) — Joint Stock Company The KK is the most widely recognised and credible corporate structure in Japan. It is a separate legal entity with limited liability for shareholders, and is the preferred structure for companies in more traditional sectors or with specific business license requirement. Historically, the KK is seen as the most highly respected and credible entity type. Incorporation typically takes approximately two months and requires notarisation of the articles of incorporation before a Japanese notary public. The Vistra Friction Index: Where to Grow, Where to Execute (APAC Edition 2026) assigns Japan an Entity Management and Regulatory friction score of 14.6 (ranked 8th across 12 APAC markets), reflecting the fact that while online company registration is available, key steps — such as company seal (inkan) registration and KK notarisation — still require in-person handling and physical paperwork, and all legal and administrative processes must be conducted in Japanese.

Goudoukaisha (GK) — Limited Liability Company The GK is a more flexible and cost-efficient structure. It carries a lower compliance burden than a KK and is suitable for companies seeking a leaner operational footprint. In recent years, the use of the GK by many high-profile companies has increased its credibility and reputation. In most sectors, this is an appropriate choice for long-term operational presence, employment, and engaging with business partners. However, it may carry less reputational weight in certain sectors.

Branch Office A Branch Office is an extension of the foreign parent company rather than a separate legal entity. It is appropriate for companies seeking a limited commercial presence in Japan. The parent company bears full liability for the Branch Office's obligations.

A high-level comparison of these structures:

Japan has progressively liberalised its foreign direct investment (FDI) framework, and most sectors are open to 100 per cent foreign ownership. However, certain sectors — including telecommunications, broadcasting, aviation, and defence-related industries — are subject to prior notification requirements under the Foreign Exchange and Foreign Trade Act (FEFTA).

Foreign companies must assess whether their proposed business activities fall within a designated sensitive sector. Where prior notification is required, companies must file with the relevant ministry and observe a waiting period before completing the investment. Failure to comply can result in penalties and, in serious cases, orders to modify or unwind the investment.

The incorporation of a KK or GK typically takes approximately two months, owing to the wet-signature requirements. The Branch Office can generally be established within one month.

Documents originating from outside Japan — such as certificates of incorporation or board resolutions from the foreign parent — will typically require notarisation, which can add to the overall timeline.

Companies should also account for the time required to:

• Open a corporate bank account
• Register for corporate and consumption tax purposes
• Enroll in social insurance and labour insurance schemes
• Obtain any sector-specific licences or permits

The effective combined corporate tax rate for companies operating in Tokyo is approximately 29.74 per cent, comprising national corporate tax, local corporate tax, and enterprise and inhabitant taxes.

Branch Offices of foreign companies are subject to Japanese corporate tax on income attributable to their Japanese operations, at rates broadly comparable to those applicable to domestic companies.

Japan also levies Consumption Tax at a standard rate of 10 per cent on the supply of goods and services. Companies that exceed the prescribed registration threshold must register and file periodic returns.

Under the Vistra Friction Index: Where to Grow, Where to Execute (APAC Edition 2026), Japan records an Accounting and Tax Compliance friction score of 10.0 (ranked 10th of 12 markets). Beyond the statutory CIT rate of approximately 23.2%, companies must also pay local enterprise and inhabitant taxes — raising the effective burden — and maintain detailed records to access benefits under Japan's 81-jurisdiction tax treaty network, with foreign tax credits available for carry-forward up to three years.

If the Japanese entity transacts with its foreign parent or other group companies, Japan's transfer pricing rules will apply. Japanese law requires that related-party transactions be conducted at arm's length. This requires:

• Maintaining contemporaneous transfer pricing documentation
• Selecting and applying an appropriate transfer pricing method
• Filing transfer pricing disclosures as part of the annual corporate tax return

Japan's National Tax Agency has been increasingly active in transfer pricing audits. Non-compliance may result in tax adjustments, penalties, and potential double taxation.

A KK must have at least one director. There is no statutory requirement for a resident director, though in practice many banks and government agencies expect at least one locally based representative.

Companies are also required to:

• Maintain a registered address in Japan
• Appoint a representative director authorised to act on behalf of the company
• Hold annual general meetings and maintain statutory corporate records

Japan's employment framework is notably employee-centric. The Labour Contract Act makes it extremely difficult to terminate employees without objective and socially acceptable reasons — a principle that applies even where an employment contract contains termination provisions.

Key obligations upon hiring include:

• Enrolment in health insurance and employees' pension insurance
• Registration for workers' accident compensation and unemployment insurance
• Compliance with the Labour Standards Act on working hours, leave, and termination
• Income tax withholding and year-end adjustment (nenmatsu chosei)

Fixed-term contracts offer greater flexibility but must be managed carefully — employees on successive fixed-term contracts for more than five cumulative years have the right to request conversion to an indefinite-term contract.

Opening a corporate bank account in Japan can be time-consuming for newly established foreign-owned entities. Banks typically require extensive documentation and, in some cases, a physical meeting with bank representatives. A dual-banking strategy is advisable.

There are no minimum capital requirements for a KK or GK under current law, though a nominal capital amount is required at incorporation.

After incorporation, companies must complete the following before operations can commence:

• Tax registration with the relevant national and local tax offices
• Consumption Tax registration, where applicable
• Social insurance registration with the Japan Pension Service
• Labour insurance registration with the Labour Standards Inspection Office and Hello Work

Companies operating in Japan must comply with ongoing obligations, including:

• Filing corporate tax returns annually
• Filing Consumption Tax returns periodically
• Submitting financial statements to the Legal Affairs Bureau
• Maintaining statutory corporate records and conducting annual general meetings

Japan's compliance calendar is structured and time-bound. A well-organised compliance framework is essential to avoid penalties and maintain good standing with Japanese authorities.
