Japan Market Entry Checklist: Month-by-Month Timeline (First 12 Months)
A structured market entry timeline for Japan helps foreign companies sequence the regulatory, administrative, and operational steps required to establish a functioning business in the country. The process from initial entity decision through full operational readiness typically takes 3–6 months, with the exact timeline depending on entity type, bank account approval, and hiring plans. This month-by-month checklist covers the first 12 months of Japan market entry, from incorporation through first-year compliance milestones, based on the standard sequence for a Kabushiki Kaisha (KK) or Goudou Kaisha (GK) formation.
Key Takeaways
- Entity registration takes 2–4 weeks from articles of incorporation to company registry—KK formation requires notarization of the articles (定款認証, ~¥52,000) plus registration tax (¥150,000), while GK formation skips notarization and costs ¥60,000 in registration tax, making GK roughly 1 week faster and ¥140,000 cheaper.
- Bank account opening is the most common bottleneck—megabanks take 4–8 weeks and frequently reject new foreign-owned entities, while digital banks (GMO Aozora, SBI Sumishin) approve accounts in 1–2 weeks and should be applied to first.
- Tax and social insurance registrations must be filed within strict deadlines—corporate tax registration is due within 2 months of incorporation, consumption tax registration depends on capital amount, and social insurance enrollment is required from the date of incorporation even with zero employees.
- First employee hire triggers labor insurance obligations within 10 days—employment insurance and workers' accident insurance enrollment must be completed within 10 days of the first hire, with separate filings to the Public Employment Security Office (Hello Work) and the Labour Standards Inspection Office.
- The first fiscal year-end brings the heaviest compliance burden—corporate tax filing is due within 2 months of fiscal year-end, requiring completed financial statements, consumption tax return, corporate inhabitant tax, and enterprise tax filings, typically necessitating a Japanese tax accountant (税理士).
Pre-Entry Preparation (Month 0)
Before initiating incorporation in Japan, several foundational decisions and preparations should be completed:
- Entity type selection: Choose between KK, GK, or branch office based on market positioning, liability structure, and operational requirements. The entity comparison guide covers the decision criteria in detail.
- Registered address: Secure a physical address in Japan for company registration. Virtual office addresses are legally permitted for registration but may complicate bank account opening. The office setup guide covers options and trade-offs.
- Representative director: Identify the daihyō torishimariyaku (representative director for KK) or daihyō shain (representative member for GK). Japan no longer requires a Japan-resident director, but having one significantly simplifies banking and operations.
- Capital amount: Determine initial capital (minimum ¥1 for KK/GK, but ¥5–10 million is recommended for visa sponsorship eligibility and bank account approval). Companies with capital of ¥10 million or more are immediately subject to consumption tax.
- Fiscal year-end: Select the company's fiscal year-end date. Many foreign companies choose March 31 (aligning with Japan's standard) or match their parent company's fiscal year.
Month 1–2: Incorporation and Entity Setup
| Step | Timeline | Key Actions | Dependencies |
|---|---|---|---|
| Draft articles of incorporation (定款) | Week 1 | Define company purpose, officers, capital, fiscal year, registered address | Entity type decision, address secured |
| Notarize articles (KK only) | Week 1–2 | Submit to notary public, pay ¥52,000 notarization fee | Articles completed (not required for GK) |
| Capital deposit | Week 2 | Transfer capital to promoter's account, obtain proof of deposit | Articles notarized (KK) or completed (GK) |
| Company registration (登記) | Week 2–3 | Submit to Legal Affairs Bureau, pay registration tax (¥150K KK / ¥60K GK) | Capital deposited, all documents prepared |
| Obtain company seal certificate (印鑑証明書) | Week 3–4 | Register company seal at Legal Affairs Bureau, obtain certificates | Registration complete |
| Order company seals (hanko) | Week 1–2 (parallel) | Representative seal (実印), bank seal (銀行印), company stamp (角印) | Company name finalized |
| Apply for corporate bank account | Week 3–4 | Submit to digital bank first (GMO Aozora), then megabank | Registration certificate (登記簿謄本), seal certificate |
| Tax registrations | Week 4–8 | File with tax office (設立届), prefectural/municipal offices, register for consumption tax if applicable | Registration complete |
The incorporation date is the date the registration application is accepted by the Legal Affairs Bureau—not the date the articles are notarized or signed. All subsequent deadlines (tax filings, social insurance) count from this registration date. For detailed documentation requirements, see the post-incorporation filing guide.
Month 3–4: Banking, Tax, and Insurance Setup
With the entity registered, the focus shifts to establishing financial and compliance infrastructure:
- Bank account activation: Digital bank accounts (GMO Aozora, SBI Sumishin) should be approved within 1–2 weeks of application. Transfer initial capital from the promoter's account to the new corporate account. The bank account opening guide covers documentation requirements and common rejection reasons.
- Tax office registrations: File the Notification of Incorporation (法人設立届出書) with the district tax office within 2 months. File blue return application (青色申告承認申請書) within 3 months to access tax loss carryforward and other benefits. Submit separate notifications to prefectural and municipal tax offices.
- Social insurance enrollment: Register with the Japan Pension Service for health insurance (健康保険) and employees' pension (厚生年金) within 5 days of incorporation—this is required even when the only enrolled person is the representative director. The social insurance guide covers the enrollment process.
- Consumption tax registration: Companies with capital of ¥10 million or more must register for consumption tax from inception. Companies below this threshold are exempt for the first two fiscal years but may elect to register voluntarily if they expect significant input tax credits. Register for the Qualified Invoice System (適格請求書発行事業者) to issue compliant invoices.
Month 5–6: Operational Readiness
- Accounting system setup: Configure cloud accounting software (freee or Money Forward), connect bank feeds, set up chart of accounts following Japanese standards. The accounting software comparison covers platform selection.
- Payroll preparation: If hiring employees, set up payroll processing including income tax withholding tables, social insurance premium calculations, and residence tax special collection. Payroll must comply with Japanese labor law pay frequency requirements (at least monthly, on a fixed date).
- Visa sponsorship: If sponsoring work visas for foreign employees, submit Certificate of Eligibility (COE) applications to immigration. Processing takes 1–3 months. The company must demonstrate sufficient capital and business activity to sponsor visas.
- Office lease finalization: If moving from a virtual office to a physical space, finalize commercial lease terms. Budget for key money (礼金, 1–2 months rent), security deposit (保証金, 3–12 months rent), and guarantor company fees (保証会社, 50–100% of monthly rent).
Month 7–9: First Hire and Labor Insurance
Hiring the first employee triggers additional registration requirements:
- Labor insurance enrollment (within 10 days of first hire): Register for workers' accident insurance (労災保険) at the Labour Standards Inspection Office and employment insurance (雇用保険) at Hello Work. File the Insurance Relationship Establishment Report (保険関係成立届) and Concept of Estimate Insurance Premium Declaration (概算保険料申告書).
- Employment contract preparation: Draft contracts complying with the Labor Standards Act requirements—mandatory written disclosure of wages, working hours, work location, contract duration, and termination conditions.
- Work rules (就業規則): Required when the company reaches 10 or more employees. Must be filed with the Labour Standards Inspection Office. Even below 10 employees, having documented work rules prevents disputes and demonstrates compliance maturity.
- Withholding tax setup: Begin monthly income tax withholding and remittance to the tax office by the 10th of the following month. Apply for the semi-annual payment exception (納期の特例) if eligible (fewer than 10 employees) to reduce remittance frequency to twice yearly.
Month 10–12: First Year-End Compliance
| Filing | Deadline | Filed With | Notes |
|---|---|---|---|
| Corporate tax return | 2 months after fiscal year-end | District tax office | Requires finalized financial statements, tax adjustments |
| Consumption tax return | 2 months after fiscal year-end | District tax office | Only if registered for consumption tax |
| Corporate inhabitant tax | 2 months after fiscal year-end | Prefectural/municipal tax office | Per-capita levy (¥70,000 minimum) + income-based portion |
| Enterprise tax | 2 months after fiscal year-end | Prefectural tax office | Deductible as expense in following year |
| Annual labor insurance premium settlement | June 1–July 10 annually | Labour Bureau | Reconcile estimated vs actual premiums, pay difference |
| Social insurance monthly premium report | July 1–10 annually | Japan Pension Service | Report employee salaries for premium grade determination |
| Year-end tax adjustment (年末調整) | December (for calendar year) | District tax office | Reconcile employee income tax withholding for the year |
| Withholding tax summary (法定調書) | January 31 following calendar year | District tax office | Report all employee compensation, retirement payments, dividends |
The first fiscal year-end is the most demanding compliance period for new foreign companies. Engaging a Japanese tax accountant (税理士) by month 6 at the latest ensures financial statements and tax returns are prepared correctly. The tax filing schedule provides a comprehensive calendar of all recurring deadlines.
Market entry in Japan follows a predictable sequence, but the interdependencies between steps—bank account approval gates payroll setup, visa sponsorship requires demonstrated capital, tax filings depend on completed bookkeeping—mean that delays at any stage cascade through the entire timeline.
