Japan is simultaneously one of the most attractive and most misunderstood markets for foreign companies. The world’s fourth-largest economy offers stable institutions, premium-paying customers and famously loyal business relationships — alongside a business culture, legal system and set of administrative processes that punish improvisation.
This guide gives founders and executives a practical overview of doing business in Japan in 2026: how business actually gets done, the entity options and what they cost, hiring and banking realities, and the sequence that de-risks an entry.
How Business Gets Done: Culture in Practice
Skip the clichés about bowing; what actually affects your revenue is decision-making structure:
- Consensus before meetings (根回し, nemawashi). Japanese organizations socialize decisions privately before they’re formalized. The meeting where you “pitch” is often the ratification, not the decision — which means your champion inside the company, and the materials you give them, do most of the selling.
- The ringi process. Approvals circulate across stakeholders. Cycles are longer than Western sales expect — but a signed Japanese customer is dramatically stickier.
- Documents carry weight. Detailed Japanese-language materials — specs, case studies, company profile — are not collateral; they are the mechanism by which your champion sells you internally. See our Japanese Localization guide.
- Relationships compound. Introductions, trade shows and existing-client referrals open doors that cold outreach cannot. Budget for presence, not just campaigns.
Entity Options: KK vs. GK
Foreign companies establishing in Japan overwhelmingly choose between two structures:
| KK — Kabushiki Kaisha (株式会社) | GK — Godo Kaisha (合同会社) | |
|---|---|---|
| Perception | The classic “proper company”; strongest with enterprise clients, banks and recruits | Fully legitimate (Amazon Japan and Google Japan are GKs) but less prestigious with conservative counterparties |
| Registration & license tax | Minimum ¥150,000 (0.7% of capital if higher) | Minimum ¥60,000 |
| Articles notarization | Required (roughly ¥30,000–50,000, capital-dependent) | Not required |
| Typical setup time | ~2–3 weeks once documents are ready | ~1–2 weeks |
| Governance | Shareholders + directors; more formal | Simple member-managed structure |
| Conversion | — | Can convert to KK later |
Realistic all-in cost with professional support (registration taxes, notarization, translations, judicial scrivener and advisory fees) typically runs ¥400,000–¥1,000,000. Minimum capital is legally ¥1, but token capital undermines credibility with banks, landlords and immigration — foreign-owned companies commonly capitalize at ¥5 million or more for credibility — and note that where a Business Manager visa is involved, the October 2025 reforms raised the expected capital to ¥30 million.
A third option — the branch office (支店) of the foreign parent — avoids creating a separate company but exposes the parent to liability and is now less common than subsidiaries for operating businesses.
Visas and People
If a founder or foreign executive will run the Japan operation on the ground, the Business Manager visa is the usual route — and its requirements were raised sharply in October 2025: capital of ¥30 million (up from ¥5 million), at least one full-time employee residing in Japan, Japanese ability at JLPT N2 level (the applicant or a full-time staff member), a real office and a credible business plan. Processing takes months — start early, and see our dedicated guide to starting a business in Japan as a foreigner for the current rules and alternative paths.
On hiring: Japanese labor law protects employees strongly once hired, and dismissal is genuinely difficult. Practical implications:
- Hire slowly; use probation periods properly; document expectations in Japanese-language employment rules.
- A first “country launcher” hire matters more in Japan than almost anywhere — bilingual, senior enough to earn counterpart trust, entrepreneurial enough to work without HQ scaffolding.
- An EOR (employer of record) lets you hire one or two people before you have an entity — a legitimate validation-stage tool.
Banking, Taxes and Administration
- Bank accounts are the classic bottleneck. Japanese banks are conservative with new foreign-owned entities; expect documentation, an in-person process, and possible refusals. Online banks and newer services have eased this, but plan weeks, not days.
- Taxes in brief: effective corporate tax around 30% depending on size and locality; 10% consumption tax with registration and invoicing rules (the qualified invoice system) that affect pricing and vendor relationships from day one.
- The hanko/paperwork layer has shrunk but not vanished: a registered company seal remains standard for contracts and banking.
- JETRO (the Japan External Trade Organization) provides free advisory, temporary office space and step-by-step setup guidance for foreign companies — one of the best free resources in any major market.
This article is general information, not legal, tax or immigration advice. Entity choice, visa strategy and tax registration have long-term consequences and change with regulation — engage a qualified Japanese professional (judicial scrivener, tax accountant, immigration specialist) before filing anything.
Sequencing an Entry That Doesn’t Overcommit
Stage 1 — Validate without an entity. Sell cross-border or via marketplaces (Selling to Japan), test demand with Japanese-language marketing (Marketing in Japan), or appoint a distributor. Cost: marketing budget only.
Stage 2 — Build light presence. Localize properly, hire via EOR if needed, attend the key trade shows in your category, use JETRO’s programs. You’re proving repeatability, not scale.
Stage 3 — Incorporate. When revenue or enterprise deals require it, set up the GK or KK, open banking, and move key contracts onshore. Incorporating after validation means every yen of setup cost is servicing proven demand.
Frequently Asked Questions
Should I choose a KK or a GK?
Default to a GK if you’re validating with limited budget and your customers are consumers or tech companies — it’s cheaper, faster and convertible to a KK later. Choose a KK from the start if you’ll sell to conservative enterprises, raise from Japanese investors or recruit senior Japanese talent, where the prestige difference still matters.
How much money do I need to start a business in Japan?
Legally ¥1 of capital; practically, plan ¥400,000–1,000,000 for incorporation with professional support, capital of ¥30 million if a Business Manager visa is involved (raised from ¥5 million in October 2025), plus office and 6–12 months of operating runway. Validation-stage approaches (marketplaces, distributors, EOR hiring) cost far less and are the sensible first step for most companies.
Can a foreigner own 100% of a Japanese company?
Yes — there is no general local-ownership requirement, and full foreign ownership of a KK or GK is routine. A resident representative is no longer legally required for incorporation, though banking and practical operations are much easier with someone on the ground.
How long does setting up in Japan take?
The incorporation itself takes one to three weeks once documents are prepared, but the full sequence — documents, apostilles and translations, registration, bank account, and visa if needed — realistically spans two to four months. Bank accounts and visas, not the registration, are the usual long poles.
Where to Go Next
With the structural picture in place, the operating question becomes demand: Marketing in Japan covers how to generate it, Selling to Japan covers converting it, and Japanese Localization underpins both.
