Registering a Business in Japan: Step-by-Step for Foreign Entrepreneurs

Big Picture: How Business Registration in Japan Works

When people say “register a business in Japan”, they usually mean:

1. Choose a business structure (sole proprietor, GK, KK, branch, etc.).
2. Set up the company legally at the Legal Affairs Bureau (法務局) or register as a sole proprietor at the tax office.
3. Register for taxes and social insurance, and open a business bank account.
4. Match your business with the right visa, often the Business Manager visa or another status.

For many foreign founders, the process feels complex because company law, tax rules, and immigration rules are separate. This guide will walk you through each one and show where to be extra careful.

Step 0: Decide What You Actually Need

Before you do any paperwork, ask yourself two key questions:

1. Do I need a Japanese company at all?
   • If you are just testing the market, a sole proprietorship (個人事業主) under another visa status may be enough.
   • If you want to raise investment, hire staff, or look “serious”, a GK or KK is usually better.
2. Do I need a company for visa purposes?
   • If you need a Business Manager visa, you must have a real company and meet strict conditions (capital, office, employees).
   • If you already hold Permanent Resident, Spouse, Highly Skilled Professional, or a work visa, you may not need a Business Manager visa at all.

Types of Business Entities in Japan for Foreigners

Here are the main structures foreign entrepreneurs actually use:

Type	Japanese term	Best for	Key points for foreigners
Sole proprietorship	個人事業主	Freelancers, small side businesses	Simple registration at tax office; taxed as personal income.
Godo Kaisha (GK)	合同会社	Small–mid startups, foreign-owned SMEs	Flexible, cheap to set up, limited liability; similar to an LLC but taxed as corporation.
Kabushiki Kaisha (KK)	株式会社	Larger businesses, brands, VC-backed startups	Classic “Inc.” structure; easier for investors and listing.
Branch office	支店	Foreign companies expanding into Japan	Part of overseas company; requires registration and tax filings.
Representative office	駐在員事務所	Market research, liaison activities	Cannot do direct sales, limited activities but simpler setup.

All of these can, in principle, be used by foreign entrepreneurs. However, only some combinations work well with immigration and tax at the same time, which is why most foreign founders choose GK or KK.

Capital: Legal Minimum vs Visa Requirements

Japan made company formation legally easy:

• You can register a GK or KK with capital as low as 1 yen in theory.
• Registration and license tax is usually cheaper for a GK than a KK when capital is low.

However, immigration rules for the Business Manager visa are much stricter:

• Until 2025, the standard requirement was 5 million yen capital or two full-time employees.
• From mid-October 2025, Japan raised the requirement to 30 million yen capital, plus stricter conditions on education/experience, employees, and a vetted business plan.

So:

Legal minimum capital to form a company can be very low,
but capital for a Business Manager visa is now much higher.

If you plan to live in Japan on a Business Manager visa, read Japan Work Visa Types Explained for Foreigners carefully and consider getting professional immigration advice.

Step-by-Step: How to Register a Company in Japan (GK/KK)

Below is a simplified version of the process most foreign entrepreneurs follow when creating a GK or KK. Exact details differ by city and legal advisor, but the flow is similar.

Step 1: Clarify your business plan

Before any paperwork, define:

• Business model and services/products
• Target customers (Japan-only or global)
• Needed licenses (for example, food, real estate, finance)
• Estimated revenue and initial capital

This plan will help you talk to:

• Immigration (for Business Manager visa and Startup Visa programs)
• Banks (for account opening)
• Potential investors or partners

For financial planning, Cost of Living in Japan 2025 – Expenses Breakdown can help you understand your personal cost base while the business grows.

Step 2: Choose your company type (GK vs KK)

In short:

• Choose GK if you want: lower costs, fast and flexible operation, and are not chasing a stock market listing.
• Choose KK if you want: a classic “Inc.” structure, easier perception from Japanese clients and investors, and a possible listing in the future.

If you are unsure, many small foreign-owned businesses start as GK and later convert to KK when they scale.

Step 3: Decide the basics of the company

You will need to fix:

• Company name (in kanji, katakana, or alphabet; check for duplicates)
• Head office address (real address in Japan, not a P.O. box)
• Business purposes (a list of activities in Japanese)
• Capital amount and how it will be paid in
• Members or shareholders, and representative director
• Fiscal year end (e.g., March 31 or December 31)

The “business purposes” list is surprisingly important in Japan. If your future activities are not written there, you may have trouble with licenses or banking later, so make it broad but realistic.

For help choosing an address (including virtual offices), see Ultimate Expat Housing Guide in Japan – Renting, Bills, and Beyond to understand how office and home addresses work in Japan.

Step 4: Prepare and notarize Articles of Incorporation (定款)

For a KK:

• You must draft Articles of Incorporation, usually in Japanese.
• They are notarized at a notary office (公証役場) for a fee.

For a GK:

• Articles are still needed, but not notarized, so costs are lower.

Most foreigners use:

• A judicial scrivener (司法書士)
• An administrative scrivener (行政書士)
• Or a law firm that specializes in company registration and immigration

Trying to do everything alone in Japanese can be very stressful; professional support is usually worth the cost.

Step 5: Open a temporary bank account and deposit capital

The classic route is:

1. A founder opens a personal bank account in Japan.
2. The founder deposits the decided capital amount.
3. The founder obtains proof of deposit to show to the Legal Affairs Bureau.

After registration, you can open a corporate bank account under the company’s name. Bank procedures can be strict for new foreign-owned companies, so be ready with:

• Business plan
• Contracts or letters of intent from clients
• Visa and ID documents

To understand Japanese banking basics, check Opening a Bank Account in Japan for Foreigners.

Step 6: Apply for registration at the Legal Affairs Bureau

Next, your scrivener or you will file the incorporation documents with the Legal Affairs Bureau:

• Application form
• Articles of Incorporation
• Proof of capital deposit
• Signatures or seals of directors/members
• Registration and license tax payment proof (stamps)

Once accepted, the company will receive:

• Official registration as a legal entity
• A corporate number (法人番号) from the tax authorities

From this point, your company legally exists in Japan.

Step 7: Tax office notifications and consumption tax

Within a few weeks of registration, you must notify the tax office (税務署) and sometimes the local prefectural and municipal tax offices. Typical forms include:

• Notification of incorporation
• Notification of opening a business office
• Applications related to consumption tax (if you choose early taxation or simplified methods)
• Application for blue return (青色申告) for more flexible tax treatment

Japan’s National Tax Agency publishes official English guidelines and forms, but they are still technical. A licensed tax accountant (税理士) is extremely helpful.

Step 8: Social insurance and labor procedures

If you have employees (including yourself as a director on salary), you will normally need to register for:

• Health insurance and pension (社会保険)
• Employment insurance (雇用保険)
• Workers’ compensation insurance (労災保険)

These registrations are done at:

• Pension office
• Hello Work (public employment office)
• Labor standards office

Step-by-Step for Sole Proprietors (個人事業主)

If you already have a visa that allows you to work freely (e.g., Spouse, PR, Long-Term Resident, Highly Skilled), you might choose to become a sole proprietor instead of forming a company.

Basic flow:

1. Decide your business name (屋号) and activities.
2. Submit a Notification of Commencement of Business to your local tax office.
3. Consider applying for blue return for tax benefits.
4. Keep proper books and records for income tax and consumption tax.

This path is simpler and cheaper, but:

• It does not directly support a Business Manager visa.
• Your income is taxed as personal income, not corporate tax.

For some freelancers and consultants, this is the perfect first step before forming a company later.

Example Timeline for Registering a GK or KK

Here is a rough idea of how long each step can take if you work with a professional:

Week	Main tasks
1	Decide business plan, choose GK/KK, find address and advisor
2–3	Draft Articles of Incorporation, decide capital and members
3–4	Notarize Articles (KK), prepare bank and registration docs
4–5	Deposit capital, file incorporation at Legal Affairs Bureau
5–6	Receive registration, get corporate number, open corp bank account
6–8	Submit tax, social insurance, and labor notifications

If you also apply for a Business Manager visa, add extra time for immigration review and possible questions.

Business Manager Visa: Extra Steps for Foreign Founders

For many non-residents, the hardest part is not the company registration itself, but the visa.

From mid-October 2025, the Business Manager visa requires:

• 30 million yen capital,
• At least one full-time Japanese citizen or permanent resident as an employee,
• Either a relevant degree (often master’s level) or three years of managerial experience,
• A business plan reviewed and certified by a qualified professional (e.g., CPA or tax accountant),
• A real office space with proper lease and signboard.

This is a major jump from the older 5 million yen rule and makes pure “visa companies” much harder. If you cannot meet these numbers, your options might be:

• Enter on another status (e.g., work for a Japanese employer first),
• Use a Startup Visa program in certain cities (temporary light conditions),
• Partner with a Japanese co-founder or investor.

Tax, Accounting, and Compliance After Registration

Registration is just the beginning. To keep your business safe and compliant in Japan, you must:

• File corporate tax returns and local inhabitant taxes every year,
• Handle consumption tax once you become taxable or choose to be taxable earlier,
• Keep proper books and vouchers in Japanese or bilingual format.

Many foreign-owned companies hire a bilingual accounting firm that can:

• Handle monthly bookkeeping,
• Prepare payroll and social insurance calculations,
• File tax returns and communicate with the tax office.

Reading a full tax guide like Complete Guide to Tax Filing in Japan: Essential Information for Foreign Subsidiaries and Foreign Companies can be helpful, but it is technical, so do not be afraid to rely on professionals.

Money, Banking, and Personal Finances

When you run a company, you must separate business money and personal money.

Practical tips:

• Use your corporate account for all business income and expenses.
• Pay yourself a regular salary (if appropriate) instead of random transfers.
• Keep receipts for all major expenses (rent, transport, equipment).

Final Thoughts: Start Small, Build Properly

Registering a business in Japan as a foreign entrepreneur is absolutely possible, but it is not a one-form process. You must align:

• Company law (GK/KK/sole proprietor),
• Immigration rules (visa status and Business Manager conditions),

The smartest path is often:

1. Start with a clear but realistic plan.
2. Choose the right structure (sole proprietor vs GK vs KK) for your current stage.
3. Get help from trusted professionals for incorporation, tax, and visas.
4. Keep your books clean and your visa status safe from day one.

With patience, good advice, and steady execution, you can turn your idea into a real, registered business in Japan—and build a life here that works both on paper and in everyday reality.
