Japan: GK and KK Market Entry Guide

Why Japan

Japan is one of the world's largest economies, with high-value enterprise buyers, advanced consumer markets and strong demand for software, medtech, industrial technology and services. Customers often place a premium on local presence, local-language support and long-term relationships, which makes an entity and local team a real competitive signal.

Expect a market that rewards patience: sales cycles can be long, documentation is detailed and local business norms matter. Many foreign companies begin with a small team and expand once traction is proven.

Entity options

• Godo Kaisha (GK) - a limited liability company with simpler governance and lower setup cost. Widely used by foreign subsidiaries.
• Kabushiki Kaisha (KK) - a joint-stock company with a more formal governance structure and often a stronger reputation with large Japanese counterparties.
• Branch office - registers the foreign company in Japan, with the parent liable. Needs a local representative.
• Representative office - generally for non-revenue activities such as research and liaison.

Requirements around representatives, capital and residency have changed over time, so confirm the current rules with a local judicial scrivener or lawyer.

Setup steps and typical timelines

Phase 1 (days 1-15) often only covers preparation and initial filing in Japan; completion may fall in Phase 2. As a hedged guide:

1. Decide on the entity type, company name, business purpose, address and capital amount.
2. Prepare the articles of incorporation; for a KK these usually need notarial certification.
3. Handle translations, apostilles or certificates for foreign shareholders and officers.
4. Deposit the share capital as proof, as currently practised, then file with the legal affairs bureau.
5. Registration typically completes within roughly a week or two of filing, though preparation takes longer.
6. Register with tax and social-insurance authorities and open the corporate bank account.

Banking and payment rails

Corporate bank account opening is commonly cited as the most time-consuming step. Banks may ask for office details, a business plan, evidence of who runs the company and sometimes a resident representative. Starting early and engaging a provider with banking relationships can save weeks, though results vary by bank and profile.

Domestic transfers run on the Zengin system, widely used for payroll and supplier payments. Consumers use credit cards, mobile wallets, bank transfer and convenience-store payment, so your checkout mix matters. Cross-border and FX services are available through banks and licensed payment providers.

Tax and consumption tax basics

At the time of writing, corporate taxes combine national, local inhabitant and enterprise taxes, producing an effective rate commonly cited around 30% for larger companies, with lower rates for qualifying small companies. Transfer-pricing documentation and withholding on cross-border payments should be reviewed locally.

Consumption tax is currently 10%, with a reduced 8% for certain food and newspapers. There is a registration threshold for small businesses, and a qualified invoice system affects input-tax credits, so invoicing setup matters. Cross-border digital services have their own rules. Verify with a Japanese tax adviser.

Hiring and Employer of Record

Japanese employment law offers strong protections against dismissal, and employers must handle social insurance, employment insurance and withholding. Written work rules are required once headcount passes a threshold. Foreign hires generally need an appropriate visa status.

An EoR can employ initial staff without an entity, handy for a sales lead or technical specialist. GrowGlobal24 is not an employer; we help you compare independent EoR providers and plan the later move onto your own payroll.

Common pitfalls

• Starting bank onboarding too late.
• Skipping Japanese-language materials and invoices.
• Underestimating document legalisation and translation time.
• Ignoring social-insurance enrolment duties.
• Choosing a representative-office route and then needing to sell.

Illustrative example: a Boston-based analytics scaleup plans a Tokyo launch with one sales lead. It hires through an EoR in the first quarter, files a GK in parallel, and moves the hire onto its own payroll once the bank account is live.

Beyond the example above, plan a short list of owner tasks early: who holds the company seal arrangements, who signs as representative, which advisers handle tax and social-insurance registrations, and who prepares Japanese-language invoices and contracts. Keeping these decisions visible in a single plan helps the project stay inside the 90-day horizon, even where filings run longer than expected.
