Japan Company Registration: A Complete Guide for Foreign Businesses

Foreign businesses entering Japan have four main entity structures to choose from. Each carries different legal obligations, cost profiles, tax treatments, and levels of local credibility. The right choice depends on your expansion goals, investment appetite, and how much operational autonomy you need.

Entity Type	Liability	Min. Capital	Local Director Required	Best For
KK (Kabushiki Kaisha)	Limited	¥1 (practical min. ¥500,000+)	Recommended	Long-term market presence, enterprise clients
GK (Godo Kaisha)	Limited	¥1	No	Startups, lean operations, holding structures
Branch Office	Unlimited (parent liable)	None	Yes (representative)	Testing the market, existing revenue
Representative Office	N/A (non-commercial)	None	No	Market research, liaison activities only

The two most common choices for foreign businesses establishing a genuine operational presence are the KK and the GK. We cover both in depth below.

A Kabushiki Kaisha (KK) is Japan’s most recognized and prestigious corporate structure — the equivalent of a corporation or public limited company. For foreign businesses targeting enterprise clients, government contracts, or long-term brand building in Japan, the KK remains the gold standard.

Core Requirements

• Minimum capital: Legally ¥1, but practically ¥500,000–¥1,000,000 is advisable for bank account opening and credibility
• At least one representative director (can be a foreign national)
• No mandatory residency requirement for directors, though having a Japan-resident representative director simplifies operations significantly
• Corporate seal (hanko) registration is required
• Articles of incorporation must be notarized by a Japanese notary public

Governance Structure

A KK issues shares and can have multiple classes of shareholders. It requires a representative director (daihyo torishimariyaku) who has binding legal authority to act on behalf of the company. Depending on company size and articles of incorporation, you may also need an auditor (kansayaku).

Pros of the KK Structure

• Highest credibility with Japanese clients, banks, and partners
• Familiar structure for enterprise procurement departments
• Easier to raise capital through share issuance
• Clear path to listing on Japanese stock exchanges if relevant
• Well-understood by Japanese accountants, lawyers, and tax authorities

Cons of the KK Structure

• Higher setup cost due to mandatory notarization (~¥52,000 notary fee)
• More complex governance requirements
• Articles of incorporation changes require additional notarization
• Slightly longer registration timeline than a GK

For most foreign businesses planning a serious market entry — particularly those targeting B2B enterprise sales — the KK is worth the additional setup cost. See our Japan Go-to-Market Strategy guide for context on how entity choice affects your broader market approach.

A Godo Kaisha (GK) is Japan’s limited liability company structure, introduced in 2006 under the Companies Act. It offers flexibility and lower setup costs while still providing full limited liability protection. Many foreign holding companies and tech startups use the GK for Japan operations.

Core Requirements

• Minimum capital: ¥1 (no practical minimum, though ¥100,000+ is advisable)
• At least one member (shain) who also acts as a representative member (daihyo shain)
• No requirement for a Japan-resident director, though it helps with bank accounts
• No notarization requirement — articles of incorporation can be self-authenticated
• Corporate seal registration still recommended

Governance Structure

Unlike a KK, a GK has “members” rather than shareholders and “directors.” Management rights belong to members by default. This makes it simpler and cheaper to operate but less familiar to traditional Japanese corporate counterparts.

Pros of the GK Structure

• Significantly lower setup cost (no notary fee — saves ~¥52,000)
• Faster registration timeline
• Simpler governance — fewer mandatory formalities
• Preferred by US multinationals for tax transparency reasons (treated as a pass-through in some jurisdictions)
• No statutory audit requirements for small companies

Cons of the GK Structure

• Lower brand recognition among traditional Japanese businesses
• Some larger Japanese corporations are unfamiliar with the structure and may perceive it as less established
• Cannot issue multiple share classes or conduct an IPO without converting to a KK
• Converting from GK to KK later requires a separate legal process

The GK is an excellent choice for startups, SaaS companies, holding entities, and businesses testing Japan before full commitment. Our consultation services can help you determine which structure fits your specific situation.

Branch Office (Shiten)

A branch office is an extension of the parent company — not a separate legal entity. The parent company bears full legal liability for the branch’s activities. Registration requires appointing a representative in Japan.

Branch offices can conduct commercial activities, generate revenue, and enter contracts in Japan. However, because the parent company is directly liable, this structure carries more risk than a subsidiary. Japanese banks may also require additional documentation and may be more cautious when opening accounts for branch offices.

Branch offices are best suited for companies that:

• Already have established revenue streams they want to formalize in Japan
• Want to avoid creating a separate legal entity initially
• Have strong parent company financials that can underpin the branch’s credibility

Representative Office (Chuzaiin Jimusho)

A representative office is not a legal entity and cannot conduct revenue-generating activities in Japan. Its permitted activities are strictly limited to market research, liaison, information gathering, and promotional activities on behalf of the parent company.

Representative offices do not require formal registration with the Legal Affairs Bureau, though they may need to register with local tax authorities depending on activities. They cannot sign contracts, invoice clients, or hire employees directly.

Representative offices are appropriate when:

• You’re conducting early-stage market research before committing to a full entity
• Your Japan activity is purely liaison or coordination with no local commercial activity
• You want to establish a physical presence for relationship-building without full legal commitment

For most businesses beyond the earliest research phase, a KK or GK provides more operational flexibility with comparable simplicity of setup.

Registering a company in Japan follows a defined sequence. Working with a local judicial scrivener (shiho shoshi) or lawyer significantly reduces errors and delays.

Step 1: Decide on Entity Type and Structure (Week 1)

Choose between KK, GK, branch, or representative office. Determine capital amount, director structure, and fiscal year end. Decisions made here affect notarization requirements, registration fees, and ongoing obligations.

Step 2: Reserve or Confirm Company Name (Week 1)

Japanese company names must include the entity type designation: “株式会社” (Kabushiki Kaisha) or “合同会社” (Godo Kaisha), which can appear before or after the company name. Search the Legal Affairs Bureau database to confirm your desired name is available.

Step 3: Obtain a Corporate Seal (Hanko) (Week 1–2)

Order a corporate seal (company inkan) from a seal maker. For KK registration, you’ll need at minimum a representative director’s seal. Allow 1–3 business days for production. The seal must be registered with the Legal Affairs Bureau as part of incorporation.

Step 4: Draft Articles of Incorporation (Week 1–2)

The articles of incorporation (teikan) define your company’s name, purpose, capital, share structure (for KK), and governance rules. For a KK, these must be drafted carefully as they require notarization. Standard templates exist but should be reviewed by a professional.

Step 5: Notarize Articles of Incorporation — KK Only (Week 2)

Take the articles of incorporation to a notary public (koshonin) in Japan. This step is mandatory for KKs and costs approximately ¥52,000. GKs skip this step entirely. Notarization requires original documents and the presence of directors or their authorized proxy.

Step 6: Open a Capital Deposit Account (Week 2–3)

Deposit the full stated capital amount into a personal bank account (typically the representative director’s account) as evidence of capital contribution. Obtain a bank passbook copy and statement showing the deposited amount. This evidence is required for registration. Note: this is not the corporate bank account — it’s a temporary holding account.

Step 7: File Registration with the Legal Affairs Bureau (Week 3–4)

Submit the completed registration application to the Legal Affairs Bureau (Homukyoku) in the jurisdiction where your registered address is located. Required documents include: articles of incorporation, capital deposit evidence, director/member consent forms, seal registration forms, and registration tax payment receipt. Registration tax for a KK is 0.7% of stated capital (minimum ¥150,000). For a GK, the minimum is ¥60,000.

Step 8: Receive Certificate of Incorporation (Week 4–5)

Processing takes approximately 1–2 weeks. Upon completion, you’ll receive a company registration certificate (touki jiko shomeisho) and can order certified copies. The company is now legally established.

Step 9: Open a Corporate Bank Account (Week 4–6)

This is often the most time-consuming step. Japanese banks require extensive documentation, including company registration certificates, articles of incorporation, seal registration certificates, and director identification. Major city banks (Mitsubishi UFJ, Sumitomo Mitsui, Mizuho) are selective about new company accounts. Regional banks and online banking services (GMO Aozora, Paypay Bank) may be more accessible for newly incorporated foreign-owned entities.

Step 10: Register with Tax Authorities (Week 5–7)

File with the National Tax Agency (tax office), prefectural tax office, and municipal tax office within two months of incorporation. Register for consumption tax (if applicable), corporate income tax, and withholding tax as appropriate.

Having the right documents prepared before starting the registration process prevents delays. Requirements differ slightly between KK and GK structures.

For KK Registration

• Articles of incorporation (notarized original + copies)
• Notarization receipt from notary public
• Certificate of registered seal for representative director (from municipal office)
• Director consent forms (signed)
• Evidence of capital deposit (bank passbook copy + statement)
• Registered office address evidence (lease agreement or property deed)
• Registration tax payment receipt (¥150,000 minimum)
• Representative director’s personal seal registration certificate

For GK Registration

• Articles of incorporation (self-authenticated, no notarization needed)
• Member (shain) consent forms
• Evidence of capital deposit
• Registered office address evidence
• Registration tax payment receipt (¥60,000 minimum)
• Representative member’s personal information and seal

For Foreign Nationals

If any directors or members are non-Japanese nationals residing outside Japan, additional documentation is required:

• Notarized and apostilled signature certificate from home country (in lieu of seal registration certificate)
• Certified translation of foreign documents into Japanese
• Passport copies

Allow extra time if documents need to be apostilled in your home country — this can add 2–4 weeks to the process.

Understanding the full cost picture prevents surprises. Costs fall into three categories: one-time setup costs, professional fees, and ongoing operational costs.

One-Time Government Fees

Item	KK	GK
Notarization fee	¥52,000	Not required
Registration tax	¥150,000 min (0.7% of capital)	¥60,000 min (0.7% of capital)
Revenue stamps (articles)	¥40,000	¥40,000
Seal registration	¥2,000–¥5,000	¥2,000–¥5,000
Subtotal	~¥244,000+	~¥102,000+

Professional Service Fees

Service	Estimated Cost
Judicial scrivener (shiho shoshi)	¥150,000–¥300,000
Legal review and articles drafting	¥100,000–¥250,000
Tax registration assistance	¥50,000–¥100,000
Translation (foreign docs)	¥30,000–¥80,000
Apostille processing (varies by country)	¥10,000–¥50,000

Ongoing Annual Costs to Budget

• Registered address service (if using a virtual office): ¥50,000–¥150,000/year
• Corporate resident tax (minimum): ¥70,000/year even with no profit
• Tax filing (accounting firm): ¥300,000–¥600,000/year depending on complexity
• Annual compliance and reporting: ¥100,000–¥200,000/year

Total first-year all-in cost for a KK with professional support typically ranges from ¥700,000 to ¥1,500,000 depending on capital amount and service provider.

Most straightforward registrations complete within 4–8 weeks, assuming documents are prepared correctly and no revisions are required.

Week	Milestone
Week 1	Entity type decision, name confirmation, seal order
Week 1–2	Articles of incorporation drafted and reviewed
Week 2	Notarization (KK only), capital deposit
Week 3–4	Registration application filed with Legal Affairs Bureau
Week 4–5	Registration certificate issued
Week 4–6	Corporate bank account opened
Week 5–7	Tax authority registrations completed
Week 6–8	Social and labor insurance registrations (if hiring)

Delays most commonly occur at two stages: document preparation (particularly for foreign nationals needing apostilles) and corporate bank account opening. Building buffer time into both is advisable, especially if your timeline is tied to a commercial deadline.

Completing Legal Affairs Bureau registration is only the beginning. Several additional registrations are required within specific timeframes.

Tax Registrations

Within two months of incorporation, file notifications with:

• The relevant district tax office (zeimusho) for corporate income tax
• The prefectural tax office for prefectural corporate tax
• The municipal tax office for municipal corporate tax

If annual taxable sales are expected to exceed ¥10,000,000, consumption tax (10%) registration may also be required. Newly incorporated companies are generally exempt for the first two years unless they elect to register voluntarily.

Social Insurance (Shakai Hoken)

Companies with even one employee — including a full-time director receiving remuneration — must register for social insurance (health insurance and pension) with the Japan Pension Service within five days of incorporation. This is a legal obligation, not optional.

Labor Insurance

If you hire employees, you must register for:

• Workers’ accident compensation insurance (rodo saigai hoken) with the Labor Standards Inspection Office
• Employment insurance (koyo hoken) with the Hello Work public employment service office

Both registrations are required from the date the first employee joins.

Corporate Seal Registration at Municipal Office

While the corporate seal is registered at the Legal Affairs Bureau during incorporation, directors may also need to register their personal seals (jitsuin) at their local municipal office for various ongoing business transactions.

Our legal services team can manage all post-registration filings on your behalf to ensure full compliance from day one.

Even well-prepared foreign companies regularly encounter the same set of avoidable problems. Knowing these in advance dramatically reduces friction.

Capital Amount Misconceptions

While Japan’s minimum capital requirement is technically ¥1, setting capital too low creates practical problems. Banks use capital as one indicator of credibility — companies with ¥100,000 or less in stated capital often struggle to open accounts at major banks. A practical minimum of ¥500,000–¥1,000,000 for a KK is advisable. For businesses applying for certain business licenses (staffing, financial services, etc.), minimum capital requirements are set by sector regulations and are significantly higher.

Director Residency Requirement Confusion

Japan does not legally require a KK to have a Japan-resident director. However, in practice, many banks will not open a corporate account without at least one director (or a guarantor) residing in Japan. This creates a common chicken-and-egg problem: you need a bank account to operate, but the bank wants a local director you haven’t yet hired. Planning for this early — or using a nominee director service while you establish local presence — prevents significant delays.

The Seal (Hanko) Culture

Japan’s corporate seal (kaisha inkan) carries legal weight that foreign businesses frequently underestimate. The registered corporate seal can authorize contracts, open bank accounts, and bind the company legally. Keeping it secure, maintaining proper seal registration certificates, and understanding when it’s required versus when a signature suffices are all essential operational knowledge. Lost or stolen corporate seals require a formal re-registration process that takes time and money.

Registered Address Requirements

Your company’s registered address must be a real, verifiable location — not a PO box. Many foreign businesses use virtual office services, which is acceptable as long as the service provider allows official mail and corporate registration. Verify this explicitly before signing a virtual office agreement. Changing your registered address later requires a paid Legal Affairs Bureau filing.

Fiscal Year Timing

Japan’s default corporate fiscal year runs April to March, but you can choose any 12-month period. Your fiscal year affects your first tax filing deadline and how long before you need a full accounting team in place. Most foreign companies align Japan’s fiscal year with their global reporting calendar — plan for this from the start.

Underestimating the Bank Account Process

Major Japanese banks (Mitsubishi UFJ, SMBC, Mizuho) have become significantly more stringent about opening accounts for newly incorporated foreign-owned entities since 2017 anti-money-laundering reforms. Expect detailed questionnaires about your business model, customer profile, and transaction flows. Having a Japanese-speaking representative and complete English/Japanese documentation prepared substantially improves success rates. Allow 4–8 weeks for this process alone.
