Registering a Company in Japan: Step by Step Process for Foreigners

Starting a business in Japan is a realistic goal for foreigners—and the country actively welcomes foreign investment. Whether you're launching a tech startup, opening a consulting firm, or establishing a local operation for your overseas company, Japan offers a stable legal framework, a sophisticated market, and excellent infrastructure. This guide walks you through every step of the company registration process, covering legal structures, costs, required documents, and key considerations for non-residents.

Types of Business Structures in Japan

Before diving into the registration process, you need to choose the right legal entity for your business. The most common options for foreign entrepreneurs are:

Kabushiki Kaisha (KK) — Joint-Stock Company The KK is Japan's most established corporate structure, equivalent to a C-corporation or "Co., Ltd." in other countries. It carries the highest level of credibility with Japanese banks, clients, and investors, making it the preferred choice for businesses seeking external funding or major B2B contracts. However, it involves more paperwork and higher setup costs.

Godo Kaisha (GK) — Limited Liability Company Introduced in 2006, the GK is Japan's version of an LLC. It's faster to set up, cheaper, and requires less ongoing administrative overhead. There is no notarization requirement for the Articles of Incorporation. For solo entrepreneurs, freelancers-turned-business owners, and small teams, the GK is often the smarter choice.

Branch Office If you already operate a foreign company, you can open a Japan branch without creating a separate legal entity. The parent company remains fully liable for the branch's activities. This is appropriate for companies wanting a market presence without full incorporation.

Representative Office The lightest structure—suitable for market research and liaison activities only. No sales or revenue-generating activities are permitted, and the office typically cannot open a corporate bank account independently.

Step-by-Step Company Registration Process

Step 1: Choose a Company Name

Your company name must be written in Japanese characters (kanji, hiragana, or katakana), though you can also register an English name alongside it. For a KK, the words 株式会社 (kabushiki kaisha) must appear in the official name—either before or after your business name. Verify your chosen name is not already registered by searching the Legal Affairs Bureau's online registry.

Step 2: Secure a Registered Office Address in Japan

Every Japanese company must have a registered office address at the time of incorporation. This is the official address where legal documents will be delivered. You do not need to rent a full physical office—a virtual office address is acceptable for most company types. Virtual office services in Tokyo's business districts typically cost ¥1,000–¥10,000 per month.

Note: Under the updated Business Manager visa rules (effective October 2025), a physical office—not a virtual one—is now required if you're applying for that visa category.

Step 3: Prepare Articles of Incorporation

The Articles of Incorporation (定款, teikan) define your company's purpose, share structure, officer roles, and governance rules. For a KK, the articles must be:

• Drafted in Japanese
• Signed by all incorporators
• Notarized by a Japanese notary public (cost: ¥30,000–¥50,000)

For a GK, notarization is not required, which reduces both cost and time.

Key elements to include:

• Company name and address
• Business objectives (be broad enough to cover future activities)
• Total authorized share count (for KK)
• Names of initial directors/members
• Fiscal year end date

Step 4: Create a Company Seal

A company seal (会社印鑑, kaisha inkan) is essential for official transactions in Japan. You'll need at minimum a representative seal (代表者印), which must be registered with the Legal Affairs Bureau. Additional seals for invoices and banking are also common. A basic seal set costs ¥5,000–¥30,000 depending on material and engraver.

Step 5: Deposit Capital

Transfer your initial capital into a personal bank account (the company doesn't have a bank account yet at this stage). You'll need to obtain a bank statement showing the deposit, which serves as proof of capital payment for registration. There is no minimum capital requirement by law—technically ¥1 is sufficient. However:

• ¥5,000,000+ is recommended if you plan to sponsor employee visas
• ¥30,000,000+ is now required for the Business Manager visa (updated October 2025)

Step 6: Submit Registration Documents to the Legal Affairs Bureau

File all required documents at the Legal Affairs Bureau (法務局, Homukyoku) in the jurisdiction where your registered office is located. Required documents include:

• Articles of Incorporation (notarized copy for KK)
• Registration application form
• Director/member list with seals or signatures
• Capital deposit evidence (bank statement)
• Office occupancy proof (lease agreement or consent letter)
• Seal registration card application

Processing time is approximately 3 business days for standard submissions. Online submission through the Ministry of Justice's e-filing system can sometimes be completed in 24 hours for eligible KK and GK applications.

Step 7: Receive Your Corporate Registration Number

Once approved, your company receives a 13-digit corporate number (法人番号). This is your official business identifier used for tax filings, banking, and government procedures. You can immediately order certified copies of your corporate registry extract (登記簿謄本, tokibo tohon), which most banks and government offices will require.

Post-Registration Requirements

Company registration is not the final step. Several important notifications must be filed promptly after incorporation:

Missing these deadlines can result in penalties and loss of tax benefits, particularly the Blue Form (青色申告) designation which offers significant deductions.

Visa Considerations for Foreign Founders

Your visa status determines what business activities you can legally undertake in Japan. Key visa categories for entrepreneurs:

Business Manager Visa (経営・管理) The primary visa for foreign nationals running a business in Japan. Requirements were significantly tightened in October 2025:

• Minimum capital: ¥30,000,000
• At least one full-time employee (Japanese national or permanent resident)
• Physical office space (virtual offices no longer acceptable)
• Japanese language ability at B2 level or higher
• Expert-reviewed business plan

Startup Visa Approved municipalities offer a preparatory period of up to 2 years for foreign entrepreneurs to develop their business before transitioning to a Business Manager visa. This is an excellent option for early-stage founders who cannot yet meet the Business Manager requirements.

Highly Skilled Professional (HSP) Visa A points-based system that may allow eligible individuals to found a business as an authorized activity, with faster processing than standard visas.

If you already hold a work visa or permanent residency, verify that starting a business is permitted under your current status. For general guidance on Japan's visa framework, see our Complete Guide to Japan Visa and Immigration.

Costs Summary

Here is a realistic cost breakdown for registering a GK and KK in Japan:

These are setup costs only. Ongoing expenses include annual corporate tax filings, accountant fees, and social insurance contributions.

Banking After Registration

Opening a corporate bank account is one of the most challenging steps for newly registered companies, especially foreign-owned ones. Japanese banks conduct rigorous KYC/AML screening and may decline applications based on internal criteria. Required documents typically include:

• Corporate registry extract (登記簿謄本)
• Articles of Incorporation
• Company seal certificate
• Director's identification documents
• Business plan
• Office lease agreement

Some banks require the business to have been operating for 3–6 months before they'll open an account. Online banks and fintech services (like GMO Aozora or Paypay Bank) tend to be more accessible for new companies and foreign founders.

Tax Obligations for Japanese Companies

All Japanese corporations are subject to multiple layers of taxation:

• National corporate tax: approximately 23.2% of taxable income
• Local corporate tax: approximately 10.3% of national corporate tax
• Inhabitant tax: fixed amount + percentage of income
• Enterprise tax: based on income, capital, or value-added (depends on company size)

A new 4% special defense surtax will apply for fiscal years beginning April 1, 2026 (or January 1, 2027 for calendar-year companies).

Companies with annual revenues exceeding ¥10 million are generally required to register for consumption tax (消費税). If you issue invoices, the Qualified Invoice System (インボイス制度) introduced in 2023 requires registration with the National Tax Agency to maintain client eligibility for input tax credits.

Working with a Judicial Scrivener (司法書士)

For most foreigners, working with a shiho shoshi (judicial scrivener) or gyosei shoshi (administrative scrivener) is strongly recommended. These licensed professionals specialize in:

• Preparing Articles of Incorporation in compliant Japanese
• Filing registration documents with the Legal Affairs Bureau
• Advising on company structure and visa implications
• Handling post-registration notifications

Fees range from ¥50,000–¥300,000 depending on complexity. For complex setups or if your Japanese is limited, this investment pays for itself in avoided mistakes and delays.
