What Documents Do I Need to Incorporate a Foreign Company in Japan?

What Documents Do I Need to Incorporate a Foreign Company in Japan?

Foreign companies establishing operations in Japan typically need to prepare 8–12 key documents across two parallel streams: home-country credentials (a certificate of good standing, notarized and apostilled constitutional documents, a resolution authorizing the Japan registration, passports for directors and founders) and Japan-side documents (Articles of Incorporation, seal registrations or signature certificates, director appointment documents, and proof of capital deposit). Everything issued abroad in a foreign language must be accompanied by a Japanese translation when filed with the Legal Affairs Bureau. The exact checklist depends on your home country, corporate structure, and whether you are establishing a subsidiary, branch office, or representative office.

Documentation is where most incorporation delays start. Missing or incorrectly formatted paperwork can set your registration back by weeks, so having everything ready before you begin saves rounds of back-and-forth with the Legal Affairs Bureau.

Japan's Companies Act sets the registration requirements, and the Foreign Exchange and Foreign Trade Act (FEFTA) adds inward-investment notifications for certain sectors. For foreign entities, the process is deliberately detailed, regulators want evidence that your company is real, legally registered, and authorized to do business abroad. Many founders underestimate the time needed to obtain notarizations, apostilles, and translations, which alone can add 2–4 weeks to the overall timeline. In AQ Partners' extensive incorporation experience, roughly two-thirds of delays stem from missing or incorrectly formatted international credentials, not the Japanese documents themselves.

Core Documents Required for Foreign Company Registration in Japan

The Legal Affairs Bureau (Hōmukyoku), which handles corporate registration under Japan's Ministry of Justice, requires a standardized package. Here are the non-negotiable documents from your home country:

• Certificate of Good Standing (or Certificate of Existence): Issued by your home country's corporate registry (Secretary of State, Companies House, etc.), confirming that your company is legally registered and active. In the U.S. this is usually called a "Certificate of Good Standing"; in the UK, a "Certificate of Incorporation"; elsewhere, a "Certificate of Existence" or registry extract. For Japanese registration purposes, plan on the certificate being issued within 3 months of filing, registry offices routinely treat older certificates as stale. Estimated cost: $10–$50 USD; processing time: 1–2 weeks (same-day online retrieval available in many jurisdictions).
• Articles of Incorporation or Bylaws: Your company's founding constitutional document. Articles of Incorporation in Japan require specific provisions for foreign registrants. The document must clearly state ownership structure, director names, authorized capital, and business scope, and must be notarized in your home jurisdiction and then apostilled (see below).
• Affidavit (sworn statement) as an alternative: Japan accepts an affidavit on the matters to be registered, sworn before a notary public in your home country, or before your country's embassy or consulate in Japan, in place of certain home-country certificates. This is especially common for branch registrations and can shortcut document collection when registry certificates are slow to obtain.
• Personal Passports (Directors and Founders): Valid passport copies for each director and founding shareholder. Identity verification is driven by anti-money laundering rules; banks apply additional beneficial-ownership checks when you open the corporate account. Copies must be clear and current.
• Proof of Address (Directors and Founders): A recent utility bill, bank statement, or official residency document (not older than 3 months). If you don't yet have a Japanese address, a verifiable home-country address is acceptable.
• Board Resolution or Minutes: A formal document signed by authorized officers, authorizing the company to register in Japan, appoint specific directors/representatives, and conduct business there. This must also be notarized and apostilled. Depending on your jurisdiction's corporate law, shareholder minutes may be required in addition to a board resolution.
• Notarization and Apostille: Any document issued outside Japan (articles, board resolutions, certificates) must first be notarized by a notary public in your home jurisdiction, then apostilled by the designated authority (Secretary of State in the U.S., FCDO Legalisation Office in the UK, etc.). Typical timeline: 1–3 weeks if done locally; 2–4 weeks if ordered remotely. Documents from countries outside the Hague Apostille Convention require consular legalization instead.
• Certified Japanese Translations: Foreign-language documents filed with the Legal Affairs Bureau must be accompanied by a Japanese translation of the parts necessary for the application. Japan has no sworn-translator system, so a government-certified translator is not formally required, but accuracy is essential, and professional translation is strongly recommended. Translation costs typically run ¥15,000–¥40,000 per document depending on length.
• Registered Address in Japan: Every registered entity needs a head-office address in Japan on file, Japan has no U.S.-style "registered agent" system, but corporate service providers and accounting firms commonly supply a registered address until you lease office space. For a branch office, at least one representative in Japan must be domiciled in Japan.

Japanese-Side Documents: Articles, Seals, and Director Appointments

Alongside your home-country credentials, a new Japanese subsidiary requires a set of documents prepared under Japanese law. These form the legal foundation of the entity registered with the Legal Affairs Bureau.

Articles of Incorporation (Teikan)

The Japanese Articles of Incorporation set out the company's basic structure and governance. They must include:

• Company name (exactly as it will appear in the registry)
• Business purpose (activities must align with this list)
• Head-office address (a physical, verifiable address in Japan)
• Capital amount (minimum ¥1, though ¥1 capital creates practical problems with banks and visas)
• Number of shares and share classes
• Director appointment method and term length
• Fiscal year-end (commonly March 31 or December 31)

For a kabushiki-gaisha (KK), the Articles must be authenticated by a Japanese notary (kōshōnin). The statutory fee is ¥30,000–¥50,000 depending on the capital amount, plus ¥40,000 stamp duty for paper articles, electronic articles (denshi teikan) avoid the stamp duty entirely. A gōdō-gaisha (GK) does not require notarization of its articles at all, which is one reason GKs are cheaper to form. If you are overseas, a notarized and apostilled power of attorney lets a representative in Japan handle authentication on your behalf; budget an extra 1–2 weeks for this.

Seals and Signature Certificates

Japan's registration system still runs on seals (hanko), with an accommodation for foreigners who don't have them:

• Corporate seal (kaisha-in): A carved company seal (typically ¥5,000–¥15,000) is prepared before filing and notified to the Legal Affairs Bureau together with the registration application. After registration, the Bureau issues corporate seal certificates on request.
• Personal seal certificates (inkan shōmeisho): Japan-resident incorporators and representative directors submit personal seal certificates issued by their municipal office, dated within 3 months.
• Signature certificates for non-residents: Directors and incorporators who live outside Japan cannot register a personal seal, so they instead submit a signature certificate (sworn attestation of their signature) issued by a notary public in their home country or their embassy/consulate.

Director Appointment and Capital Documents

• Incorporators' decisions and director appointment documents, plus each director's letter of acceptance of office
• Representative director selection document, where applicable
• Proof of capital deposit: after the Articles are authenticated, the incorporator deposits the capital into a personal Japanese bank account (the company account comes after registration), and a copy of the passbook or statement evidences the deposit. The deposit must happen after the Articles are completed but before the registration application is filed.

Since a March 2015 Ministry of Justice rule change, a KK can be registered even if no representative director resides in Japan, though in practice, opening a bank account and receiving the capital deposit is far easier with at least one Japan-resident director or a local partner. Many foreign founders delegate the in-Japan steps to a judicial scrivener (shihō shoshi) or their incorporation service provider.

Step-by-Step Document Assembly and Timing

Most foreign founders underestimate the 6–12 week timeline for document collection and preparation. Timing matters because Japanese registry practice expects supporting certificates to be issued within 3 months of filing. If you order your Certificate of Good Standing too early, it will go stale before you file; most incorporators time the order to land 2–3 weeks before the planned filing date.

Typical sequence:

1. Decide on structure (branch vs. subsidiary): 1–3 days. A branch is simpler but limits tax planning; a subsidiary is often preferred for liability and credibility reasons. Back office outsourcing partners can advise on the right structure for your situation.
2. Start apostille and certificate requests immediately, in parallel. This is the most commonly underestimated step, apostille processing takes days in some jurisdictions and weeks in others, and it gates everything downstream.
3. Draft Japanese Articles of Incorporation (if new subsidiary): 2–7 days. If registering an existing company as a branch, your existing (apostilled, translated) articles are used instead.
4. Notarize home-country documents: 2–5 days with a local notary public.
5. Order apostilles from the designated authority: 1–14 days depending on jurisdiction; some U.S. states offer 2–3 day expedited service.
6. Obtain the Certificate of Good Standing: 1–14 days; order it last so it is fresh at filing.
7. Japanese translations: 5–10 days for a typical document set.
8. Notarize Japanese Articles, deposit capital, assemble the package, file with the Legal Affairs Bureau. Registration itself is fast: in principle about 3 business days outside peak periods, and fully online applications meeting certain conditions are processed within 24 hours.

The consolidated sequence for a foreign-founded KK looks like this:

Total elapsed time: 6–12 weeks for most foreign founders, JETRO's own guidance estimates roughly two to three months from finalizing the company profile. Expedited notary/apostille services and an experienced local agent can compress this to 6–8 weeks; slow apostille jurisdictions and translation rework push it toward 10–12.

Document Requirements by Jurisdiction: Key Variations

Japan accepts documents from any country, but certificate formats, issuing authorities, and apostille turnaround vary significantly. Below is a comparison of top origin jurisdictions:

The practical difference is translation workload: every foreign-language document needs a Japanese translation for filing, but English-language jurisdictions (US, UK, Singapore, Hong Kong, Australia, Canada) tend to produce shorter, standardized certificates that are quick to translate, while German and French registry extracts are longer and add 1–2 weeks of translation lead time.

Apostille and Notarization Explained: Why They Matter

Many foreign founders encounter "apostille" for the first time during Japan incorporation. An apostille is a certificate of authentication issued by a designated government authority that verifies the signature and seal of the notary or official who executed your document. It exists because of the 1961 Hague Apostille Convention, to which Japan is a contracting party. Without it, Japanese authorities cannot verify that a foreign notarization is genuine. (For documents from non-member countries, consular legalization through a Japanese embassy replaces the apostille.)

The process is sequential and non-optional:

1. Step 1: Notarize your document with a notary public in your home country. Cost: $10–$25 USD per document; usually same-day.
2. Step 2: Obtain the apostille from the designated authority (Secretary of State in the U.S., FCDO in the UK, DFAT in Australia, etc.). Cost: roughly $5–$50 USD per document in government fees; timeline 2–14 days.
3. Step 3: Translate and submit to Japan. The apostilled document, with its Japanese translation, is now legally recognized without further authentication.

Common mistake #1: Submitting a notarized document without an apostille. The Legal Affairs Bureau will bounce it, adding 2–4 weeks to your timeline.

Common mistake #2: Assuming your notary can issue the apostille. Notarization and apostille are two separate processes handled by different authorities.

Common mistake #3: Apostilling the translation. The apostille belongs on the original document; the Japanese translation accompanies it but is not itself apostilled.

Cost and timing summary for a typical US-based company:

• Notarization: $10–$25 per document (same day)
• Apostille: $15–$40 per document (3–14 days standard; 2–3 days expedited)
• Certificate of Good Standing: $10–$50 (5–14 days standard; 1–3 days expedited)
• Japanese translation: $100–$350 per document
• Total for a typical 3-document package: $200–$500 USD (before translation)
• Document-preparation timeline: 2–4 weeks expedited; 6–10 weeks standard

Additional Documentation for Specific Scenarios

Depending on your structure, industry, and shareholder profile, you may need supplementary documents.

Subsidiary (kabushiki-gaisha or gōdō-gaisha): a separate Japanese legal entity, fully subject to Japanese law. In addition to the core package:

• Parent company's certificate of good standing and articles of incorporation
• Parent company resolution authorizing the subsidiary's establishment
• Shareholder registry or cap table if ownership is layered; a certificate of good standing for any corporate shareholder
• Beneficial ownership declarations for bank KYC, especially where ownership runs through trusts or SPVs

Subsidiaries offer liability protection and tax treaty eligibility but require ongoing accounting and compliance filings in Japan.

Branch office (shiten): not a separate entity, an extension of the foreign parent. Requires:

• Parent's certificate of incorporation and certificate of good standing (or an affidavit covering the registrable matters)
• Board resolution authorizing the branch and appointing the representative in Japan (at least one representative must be domiciled in Japan)
• Parent's articles of association, apostilled and translated

Branch registration is simpler than a subsidiary, but all branch income is subject to Japanese corporate tax, and returns must be filed even in loss years.

Representative office (chūzaiin jimusho): a liaison presence for market research and coordination only, it cannot conduct sales. No Legal Affairs Bureau registration is generally required, which is why it can be set up in 2–3 weeks. Any commercial activity triggers the need to register a branch or subsidiary.

For VC/PE funds and family offices: Fund administration services in Japan require additional regulatory documentation, including fund strategy documentation, investor agreements, and beneficial ownership disclosures. These sit outside the incorporation file but should be assembled in parallel.

If your company has undergone recent M&A or restructuring: include the certificate of merger or consolidation, records of name changes or charter amendments, and updated articles reflecting all changes.

Common Document Errors and How to Avoid Them

In AQ Partners' incorporation practice, most Legal Affairs Bureau delays trace to document errors rather than missing documents. The errors are usually simple but cost 2–4 weeks each to fix:

Translation and Apostille Errors

• Apostille applied to the wrong document: the apostille must authenticate the original; translations accompany but are never apostilled.
• Missing translations: every foreign-language attachment needs a Japanese translation of the relevant parts. Filings without them are returned.
• Sloppy translation of names and addresses: the katakana/romaji rendering of company and director names must be consistent across every document in the package.

Articles of Incorporation Errors

• Overly broad or vague business purpose: if your stated purpose doesn't match your actual business, licensing and tax issues surface later. Be specific.
• Inconsistent company name: the name in the Articles must exactly match the seal notification and every other filing document, even a spacing or punctuation difference causes rejection.
• Missing notary authentication (KK): the Legal Affairs Bureau requires the authenticated original, not a copy.

Signer and Certificate Errors

• Stale certificates: seal certificates and registry certificates should be issued within 3 months of filing.
• Wrong signature evidence: Japan-resident signers need municipal seal certificates; non-resident signers need notarized signature certificates. Mixing these up is a frequent cause of requisitions.
• Capital deposited too early: the deposit must follow completion of the Articles; deposits dated before the Articles cause rejection, as does filing without deposit proof.

Timing Errors

• Late registration filing: the Companies Act requires the KK registration application within 2 weeks of completing the incorporation procedures (3 weeks for registering a branch after appointing its representative in Japan). Late filings can attract administrative fines and force documents to be refreshed.
• Ordering the certificate of good standing too early: it goes stale before filing and must be re-ordered.

Tax and Employment Registrations That Run in Parallel

Incorporation documents are only half the file, tax and employment registrations have their own statutory deadlines that start running the day your company is registered. These are filed after you receive the Certificate of Registered Matters:

Tax Office Filings

• Notification of incorporation (hōjin setsuritsu todokede-sho): file with the national tax office within 2 months of incorporation; prefectural and municipal notifications have their own (often shorter) local deadlines, e.g. 15 days in Tokyo.
• Application for blue-form tax return (aoiro shinkoku): due by the earlier of 3 months after incorporation or the last day of the first fiscal year. Missing it forfeits loss carryforwards and other significant deductions for year one.
• Consumption tax: a company generally becomes a taxable person once taxable sales exceed ¥10 million in the base period; newly established companies with capital of ¥10 million or more are taxable from year one, and voluntary registration (including qualified invoice issuer registration) may make sense if you invoice Japanese businesses.
• Withholding agent registration: required when you pay salaries or certain fees; a salary-paying office notification is due within 1 month. Withholding tax compliance requires immediate attention if you hire employees or pay contractors.

Social and Labor Insurance

• Health insurance and employees' pension (shakai hoken): new-office notification to the Japan Pension Service within 5 days of becoming an applicable workplace, which a newly registered company with paid directors or employees is.
• Workers' accident compensation insurance (rōsai hoken): establishment report within 10 days of hiring the first employee.
• Employment insurance (koyō hoken): office establishment notification within 10 days of first hiring, via Hello Work.

Late registration leads to retroactive collection of premiums plus surcharges. Outsourcing payroll and employment compliance to a specialist is common among foreign startups given the complexity.

Key Takeaways

• Plan for two parallel document streams: home-country credentials (certificate of good standing, notarized and apostilled constitutional documents, board resolution, passports, signature certificates) and Japan-side documents (Articles of Incorporation, seals, director appointments, capital deposit proof). Both must be complete before the Legal Affairs Bureau filing.
• Apostille and notarization are sequential, not simultaneous. Notarize first, then obtain the apostille from the designated authority, and put the apostille on the original, never the translation. Every foreign-language document needs a Japanese translation for filing.
• Timeline is typically 6–12 weeks end to end, driven by apostille processing and translations rather than the registration itself (about 3 business days, or 24 hours for qualifying online filings). Start apostille requests on day one, and time your certificate of good standing to be issued within 3 months of filing.
• Jurisdiction and structure drive the checklist. English-language jurisdictions produce faster document packages than civil-law registries that need longer translations; subsidiaries need parent-company credentials, branches need a Japan-domiciled representative, and representative offices generally skip registration entirely.
• Tax and employment deadlines start at registration: tax office notification within 2 months, blue-form application within 3 months (or first year-end if earlier), social insurance within 5 days, and labor insurance within 10 days of hiring. Professional Japan tax and accounting firms handle incorporation alongside tax compliance setup, ensuring nothing slips between the two workstreams.

Frequently Asked Questions

Q: Do I need to submit documents in Japanese, or is English acceptable?

Foreign-language documents can be submitted, but they must be accompanied by a Japanese translation of the parts necessary for the registration application, this applies to certificates of good standing, articles, resolutions, and signature certificates alike.

Japan has no sworn-translator system, so the translation need not come from a government-certified translator, but accuracy and consistent name rendering are essential. Budget ¥15,000–¥40,000 and 3–10 days per document. Tax compliance firms can arrange certified Japanese translations as part of incorporation support.

Q: How long is a Certificate of Good Standing valid for a Japan filing?

Japanese registry practice expects supporting certificates to be issued within 3 months of the application, the same freshness standard applied to seal certificates. If your certificate is older than that at filing, expect it to be rejected and plan to re-order (you cannot renew or extend the original). This is why most incorporators time the certificate order to land 2–3 weeks before the planned filing date.

Q: Can I use a digital/online-printed Certificate of Good Standing, or must it be an official sealed copy?

Many U.S. states, UK Companies House, ASIC (Australia), and ACRA (Singapore) issue official digital certificates with verification codes, and Japanese registry offices increasingly accept them. But acceptance is not uniform, and the apostille process itself often requires a physical original. To be safe, order the official sealed copy where available, the cost difference is minimal ($10–$20 USD) and it eliminates rejection risk.

Q: Can I incorporate a Japanese company entirely from abroad, or do I need to visit Japan?

You can complete the process without visiting Japan. A notarized and apostilled power of attorney lets a representative in Japan handle notarization and filing, and non-resident directors substitute notarized signature certificates for Japanese seal registration. Since the Ministry of Justice's March 2015 rule change, a KK no longer needs any Japan-resident representative director, though receiving the capital deposit and opening a corporate bank account are far easier with a local director or partner. Budget an extra 1–2 weeks for the POA route, and note that the POA should grant specific, limited authorities; blanket POAs are often rejected.

Q: If I'm incorporating a subsidiary in Japan (not a branch), do I still need a Certificate of Good Standing from my parent company?

Yes. Even though the subsidiary is a brand-new Japanese entity, the parent must prove its own legitimacy as founder and shareholder. The subsidiary won't have its own registry certificate until after incorporation; the parent's certificate confirms that the shareholder funding the subsidiary is real and legally registered.

Q: What does the whole document package cost?

Home-country document fees (notarization, apostilles, registry certificates) typically total $200–$500 USD for a 3-document package. On the Japan side, KK notarization runs ¥30,000–¥50,000 (plus ¥40,000 stamp duty unless you file electronic articles), the corporate seal ¥5,000–¥15,000, and registration and license tax is 0.7% of capital with a ¥150,000 minimum for a KK (¥60,000 minimum for a GK; ¥90,000 for a branch). Japanese translations add ¥15,000–¥40,000 per document across a typical 3–5 document set. Full-service professional support generally runs ¥250,000–¥500,000 end to end. Budget timelines vary significantly by structure type and complexity.

Q: What happens if my notarization or apostille is rejected by the Legal Affairs Bureau?

Rejections happen when the notarizing authority isn't recognized, the apostille is damaged or improperly attached, or the apostille was placed on a translation rather than the original. The fix is a new notarization and apostille, same cost, plus another 2–4 weeks. An experienced local agent who pre-screens documents against registry standards is the cheapest insurance against this.

Q: Do I need separate apostilles for each document, or can one apostille cover several?

Each document requires its own apostille, one certificate authenticates one notarized document. If you're submitting three documents (articles, board resolution, certificate of good standing), you need three apostilles. Some authorities batch-process orders at modest per-document rates, so ask when ordering.
