KK vs GK in Japan Which Entity Should Foreign Entrants Choose?

By Jonathon Richards

– posted 2 hours ago

Choosing the right structure for company formation Japan is the single most consequential decision a foreign founder or multinational will make before entering the market. Japan’s Companies Act offers two limited-liability vehicles that dominate foreign market entry: the Kabushiki Kaisha (KK / 株式会社) and the Godo Kaisha (GK / 合同会社). Each carries distinct implications for fundraising, governance, visa eligibility, banking relationships, and total formation cost. This page delivers a clear recommendation framework, an at-a-glance comparison, a step-by-step incorporation process for both entities, a representative-director and visa playbook, numeric cost examples, and a downloadable checklist everything needed to make a confident, informed decision.

Quick Recommendation Rules

Pick a KK if you plan to raise venture capital, pursue an IPO, or need maximum credibility with Japanese banks, partners, and regulators.
Pick a GK if you are a solo founder, a small subsidiary, or a cost-conscious entrant who values speed and flexible management over external fundraising.
Default to a KK for joint ventures with Japanese partners or any activity in a regulated sector (finance, pharma, telecoms) where corporate form matters to licensing bodies.

At-a-Glance Comparison: KK vs GK Japan

Feature	Kabushiki Kaisha (KK)	Godo Kaisha (GK)
Liability	Limited to company assets (shareholders)	Limited to company assets (members)
Governance	Formal: shareholders’ meeting, directors; optional board of directors and auditors	Flexible: member-managed (comparable to a US LLC)
Registration tax (minimum)	0.7% of stated capital minimum JPY 150,000	0.7% of stated capital minimum JPY 60,000
Notarisation of articles	Required public notary certification mandatory	Not required simpler formation
Ability to issue shares	Yes freely transferable shares (subject to transfer restrictions in articles)	No shares membership interests only
Investor suitability	High preferred by VCs, angel investors, and for IPO track	Lower sometimes accepted for wholly owned subsidiaries and small businesses
Credibility with banks / partners	High traditional corporate form with strong market recognition	Growing acceptance, though some banks and partners still prefer KK
Typical formation time	2–6 weeks (with professional support); can leverage new Feb 2 2026 designated-date rules	1–3 weeks (simpler filings, no notary step)

Who Should Pick Which: A Decision Framework for Kabushiki Kaisha vs Godo Kaisha

The choice between a KK and a GK is ultimately driven by three variables: how you intend to fund the business, how quickly and cheaply you need to launch, and how Japanese counterparties will perceive the entity.

Fundraising or exit path: If your business plan includes venture capital, convertible notes, stock options (shinkabu yoyaku-ken / 新株予約権), or a future IPO on the TSE, a KK is the only practical choice. Japanese institutional investors overwhelmingly expect equity shares, not membership interests.
Solo founder, lean launch: A single founder building a pre-revenue SaaS product or consulting practice benefits from the GK’s lower registration tax, absence of notarisation, and streamlined governance. A GK can always be converted to a KK later (kumikae / 組織変更) if fundraising needs change.
Joint venture or regulated sector: Licensing authorities and Japanese corporate partners typically expect a KK. Regulatory filings and compliance disclosures are designed around the KK governance model.
Wholly owned subsidiary: Multinationals establishing a subsidiary for internal operations often choose a GK to reduce formation cost and administrative overhead, since there is no external investor to satisfy.

How to Set Up a Company in Japan: Step-by-Step Process

KK Incorporation Numbered Steps and Timeline

Draft the Articles of Incorporation (定款 / teikan) and appoint initial directors. Prepare the articles specifying the trade name, head-office address, business purposes, stated capital, shares to be issued, and director appointments. The articles must be in Japanese. If any founding documents are in a foreign language, certified translations are required. Timeline: 1–3 days.
Notarise the articles with a public notary (公証人役場 / kōshōnin yakuba). Under the Companies Act formation requirements, KK articles must be certified by a Japanese public notary. The notary fee is approximately JPY 50,000 plus stamp duty. Founders must present valid identification (passport and, if applicable, residence card). Appointments may be booked online in most prefectures. Timeline: 1–5 days (including booking).
Deposit capital into a bank account. Capital must be deposited into either a founder’s personal Japanese bank account or, in limited cases, a non-resident account at a bank that accepts foreign transfers for formation purposes. The deposit statement (払込証明書 / haraikomi shōmeisho) evidences the capital contribution. Timeline: 1–7 days (varies by bank and founder residency).
File the incorporation application at the Legal Affairs Bureau (法務局 / hōmukyoku). Submit the notarised articles, capital deposit evidence, director appointment consents, company seal (inkan / 印鑑) registration form, and other prescribed documents. Pay the registration license tax 0.7% of stated capital with a statutory minimum of JPY 150,000. E-filing is available and can reduce processing time. From 2 February 2026, the Ministry of Justice’s amended commercial registration rules allow companies to designate a weekend or holiday as the official establishment date, giving founders more control over formation timing. Timeline: 1–14 days (typically 3–7 business days).
Complete post-incorporation notifications. Within the statutory windows (generally within two months of incorporation), file the following:
- National Tax Agency (NTA): Corporate Establishment Notification (法人設立届出書), Blue Return Application (if desired), Withholding Tax Office Registration.
- Prefectural and municipal tax offices: Local corporate establishment notifications.
- Social insurance: Pension and health insurance enrollment at the Japan Pension Service; labour insurance enrollment if hiring staff.
Timeline: ongoing, within 2 months of establishment.

Estimated total for KK formation: 2–6 weeks with professional support from a judicial scrivener (司法書士 / shiho shoshi) and tax accountant.

GK Incorporation Numbered Steps and Timeline

Prepare the Articles of Incorporation (定款). The GK articles specify the trade name, business purposes, head-office location, members, capital contributions, and profit-distribution rules. Critically, no notarisation is required this eliminates both the notary fee and the scheduling delay. Timeline: 1–2 days.
Deposit capital and file at the Legal Affairs Bureau. Prepare the capital deposit evidence, compile the registration documents (articles, member consents, company seal registration), and file the incorporation application. Pay the registration license tax at 0.7% of capital with a minimum of JPY 60,000. Timeline: 1–10 business days.
Complete post-incorporation notifications. The same NTA, local tax, and social insurance filings apply as for a KK. Timeline: within 2 months.

Estimated total for GK formation: 1–3 weeks with professional support.

Key Checklist Call-Outs

Required signatories: All founding members (KK shareholders or GK members) must sign or affix seals to the articles and appointment consents.
Certified translations: Any document in a language other than Japanese (passport, foreign corporate registration, board resolutions) requires a certified Japanese translation.
Corporate seal (inkan / 印鑑): A registered company seal is mandatory for formation. Order this early production takes 1–5 days from specialist engravers.

Representative Director and Visa Implications for Company Formation Japan

The representative director question is the single largest source of confusion for foreign founders. Here is the legal position and the practical reality.

Legal position: The Companies Act does not itself impose a Japanese residency requirement on representative directors. A KK or GK can, in principle, appoint a non-resident director. However, residency issues are driven by immigration rules, banking requirements, and operational practicalities rather than corporate law.

Immigration (Business Manager visa) criteria: The Immigration Control and Refugee Recognition Act requires applicants for Business Manager status to demonstrate an office in Japan and either (a) the capacity to employ at least two full-time residents, or (b) an investment commonly benchmarked at JPY 5,000,000. Without meeting these criteria, a foreign founder cannot obtain the visa needed to reside in Japan and manage the company.

Practical Workarounds for Non-Resident Founders

Option 1 Appoint a resident representative director: Engage a trusted local partner, employee, or professional to serve as resident representative director. This satisfies banking and postal requirements. Exercise caution with pure nominee arrangements directors owe fiduciary duties under the Companies Act, and nominee structures without genuine governance controls carry legal and reputational risk.
Option 2 Qualify for a Business Manager visa directly: Inject JPY 5,000,000 or more in capital and/or hire two or more full-time Japanese-resident employees. This allows the founder to apply for Business Manager status, move to Japan, and serve as the sole representative director.
Option 3 Municipal confirmation programs: Certain municipalities (notably Tokyo and select national strategic special zones) offer a provisional business-preparation permit allowing a foreign founder to enter Japan for approximately six months to complete company formation, office leasing, and visa conversion. Consult JETRO’s regional investment guides for current program availability.

Banking practicalities: Most major Japanese banks require at least one director with a Japanese address and residence card. Early engagement with the target bank before incorporation is strongly recommended. Prepare the Corporate Number (法人番号 / hōjin bangō), corporate registration certificate (登記事項証明書 / tōki jikō shōmeisho), and NTA filing receipts to accelerate account opening.

Capital and Registration Tax: Numeric Examples and Minimum Capital Japan

Japan’s Companies Act permits formation with as little as JPY 1 in stated capital. In practice, however, a nominal capital amount creates problems: banks may decline to open accounts, visa authorities may question the business’s viability, and counterparties may doubt the entity’s financial substance. Most advisers recommend a minimum of JPY 5,000,000 if a Business Manager visa is anticipated, or at least JPY 1,000,000 for general credibility.

Registration License Tax Calculation

The Registration and License Tax Act sets the rate at 0.7% of stated capital for company formation filings, subject to statutory minimums:

KK minimum: JPY 150,000
GK minimum: JPY 60,000

Scenario	Stated Capital	Computed Tax (0.7%)	KK Payable	GK Payable
A Low capital	JPY 1,000,000	JPY 7,000	JPY 150,000 (minimum applies)	JPY 60,000 (minimum applies)
B Higher capital	JPY 30,000,000	JPY 210,000	JPY 210,000 (exceeds minimum)	JPY 210,000 (exceeds minimum)

Typical Professional and Formation Costs

Cost Item	GK (Low–High Range)	KK (Low–High Range)
Registration license tax	JPY 60,000–210,000+	JPY 150,000–210,000+
Public notary fee (articles)	N/A	~JPY 50,000 (plus stamp/printing)
Judicial scrivener / lawyer fees	JPY 50,000–150,000	JPY 80,000–300,000+
Translation and certified copies	JPY 10,000–50,000	JPY 10,000–50,000
Company seal production	JPY 5,000–20,000	JPY 5,000–20,000
Estimated total (lean)	JPY 80,000–200,000	JPY 200,000–600,000

Additional costs may include office lease deposits (if required for visa or banking purposes) and ongoing accounting or tax-filing fees. These are not statutory formation costs but should be budgeted by any foreign founder planning Japan company formation for foreigners.

Step-by-Step Incorporation Timeline: Required Documents for KK and GK

Documents Required for Filing

KK: Notarised articles of incorporation, founder identification (passport and/or residence card), director appointment consents, capital deposit evidence (bank statement), registered company seal, head-office address proof (lease agreement or usage consent).
GK: Articles of incorporation (unnotarised), member identification, member consents, capital deposit evidence, registered company seal, head-office address proof.

Consolidated Timeline

Task	KK Duration	GK Duration	Key Dependency
Draft articles and prepare documents	1–3 days	1–2 days	Certified translations if needed
Notarise articles	1–5 days	N/A	Notary appointment availability
Capital deposit	1–7 days	1–7 days	Bank access / founder residency
File at Legal Affairs Bureau	3–14 days	1–10 days	E-filing availability; designated-date rule
Post-incorporation filings	Within 2 months	Within 2 months	NTA, local tax, social insurance
Total estimated	2–6 weeks	1–3 weeks

From 2 February 2026, Japan’s amended commercial registration rules allow companies to designate a weekend or national holiday as the official establishment date. This means founders can align their incorporation date with specific corporate or fiscal milestones without being constrained by Legal Affairs Bureau business hours a practical advantage for both KK and GK formations.

Common Pain Points for Foreign Founders and How to Solve Them

Office address (virtual vs real lease): Immigration authorities and most banks require evidence of a genuine business office. Virtual offices may suffice for initial registration at the Legal Affairs Bureau, but a real lease is typically necessary for a Business Manager visa application and for opening a corporate bank account. JETRO’s Invest Japan Business Support Center offers temporary office facilities for eligible foreign entrants.
Bank account opening: Prepare the Corporate Number, certified copy of the corporate registry, NTA filing receipts, a detailed business plan (in Japanese), and identification for all directors. Contact banks early some institutions require the representative director to appear in person and hold a residence card.
Company seal (inkan / 印鑑): Every Japanese company must register an official seal at the Legal Affairs Bureau. Order the seal as soon as the trade name is finalised. You will also need an inkan certificate (印鑑証明書 / inkan shōmeisho) for banking and contract execution.
Notarisation (KK only): The requirement for a public notary to certify KK articles adds cost (~JPY 50,000) and 1–5 days. GK formation avoids this step entirely one of the key speed and cost advantages of the GK form.
Certified translations: Any document submitted to a notary or the Legal Affairs Bureau in a language other than Japanese must be accompanied by a certified Japanese translation. Use accredited translators familiar with legal and corporate terminology.

Recommended Service Provider Types

Judicial scrivener (司法書士 / shiho shoshi): Handles registration filings at the Legal Affairs Bureau.
Administrative scrivener (行政書士 / gyōsei shoshi): Assists with permits, visa applications, and regulatory filings.
Certified public tax accountant (税理士 / zeirishi): Manages NTA notifications, blue return applications, and ongoing tax compliance.
Licensed public notary (公証人 / kōshōnin): Certifies KK articles of incorporation.
Accredited translators: Provide certified Japanese translations of foreign-language documents.

Decision Flowchart and Buyer Personas

Quick Decision Flow

Do you plan to raise venture capital or pursue an IPO? → KK.
Are you a solo founder or small team seeking speed, low cost, and flexible management? → GK.
Do you need a Business Manager visa immediately? → Evaluate capital (JPY 5,000,000+) and staffing capacity; consider a resident representative director; explore municipal confirmation programs. Entity choice then follows from funding strategy.
Are you forming a joint venture with a Japanese partner or entering a regulated sector? → KK.

Three Buyer Personas

Solo SaaS Founder Pre-Revenue, Lean Launch: GK recommended. Formation can be completed in 1–3 weeks at roughly JPY 80,000–200,000. The flexible governance structure means no formal board meetings or auditor appointments. If the product gains traction and outside investment becomes necessary, the GK can be converted to a KK through a statutory organisational change (組織変更).
Funded Startup Seed or Series A Fundraising Anticipated: KK recommended. Japanese VCs and most foreign investors expect equity shares, stock option pools, and formal shareholders’ meetings. Starting as a KK avoids the cost and delay of a later conversion and ensures investor-ready governance from day one. Budget JPY 200,000–600,000 for formation.
Multinational JV or Regulated-Sector Entry: KK recommended. A joint venture with a Japanese corporate partner almost invariably requires a KK for credibility, regulatory alignment, and compatibility with the partner’s own corporate governance expectations. Licensing bodies in finance, pharmaceuticals, and telecommunications are structured around the KK model.

FAQs

Can a foreigner start a company in Japan?

Yes. There is no nationality restriction on forming a KK or GK under Japan’s Companies Act. A foreign individual or corporation can serve as a founder, shareholder, or member. However, practical considerations — including the Business Manager visa, banking requirements, and the need for a Japanese office address — mean that foreign founders should plan the process carefully and engage local professional support. JETRO’s Invest Japan portal provides official guidance and support services for foreign market entrants.

What is the difference between a KK and a GK?

A Kabushiki Kaisha (KK) is a stock corporation with formal governance (shareholders’ meetings, directors, optional board and auditors) and the ability to issue transferable shares. A Godo Kaisha (GK) is a member-managed limited liability company with flexible governance, no share issuance, and no requirement for notarised articles. The KK is preferred for fundraising and public credibility; the GK is faster and cheaper to form.

How much does it cost to form a KK vs a GK?

The principal cost difference is the registration license tax minimum (KK: JPY 150,000; GK: JPY 60,000) and the KK’s mandatory notarisation fee (~JPY 50,000). Including professional fees, a lean GK incorporation typically costs JPY 80,000–200,000, while a KK costs JPY 200,000–600,000. Higher capital amounts or complex structures increase costs proportionally.

Do I need a resident representative director in Japan?

The Companies Act does not require a representative director to be a Japanese resident. However, most banks require at least one director with a Japanese address and residence card to open a corporate account, and immigration rules require the founder to hold a valid status of residence (such as the Business Manager visa) to live and work in Japan. Workarounds include appointing a trusted resident director, qualifying for a Business Manager visa through investment or staffing, or using a municipal confirmation program for temporary entry.

How long does incorporation take in Japan?

A GK can typically be incorporated in 1–3 weeks; a KK takes 2–6 weeks due to the additional notarisation step and more complex documentation. From 2 February 2026, the Ministry of Justice’s amended rules allow founders to designate a weekend or holiday as the official establishment date, offering greater flexibility in formation scheduling.

Which entity is better for raising outside investment — a KK or a GK?

A KK is almost always preferred for outside investment. It issues transferable equity shares, supports stock option plans, and provides the formal governance framework (shareholders’ meetings, financial reporting, optional board) that venture capital firms and institutional investors expect. A GK’s membership-interest structure is rarely compatible with standard Japanese VC term sheets or with a future initial public offering.
