Japanese Seal Registration Certificate Apostille and Certified Translation

It depends on your destination and the nature of your transaction. Here's how to decide:

• Incorporating a company in Singapore (ACRA) or New Zealand as an individual → Individual seal where requested for foreign Director registration
• Japanese parent company establishing an overseas subsidiary → Corporate seal (parent company's formal contracting authority)
• Overseas real estate purchase or sale (personal transaction) → Individual seal
• Opening an overseas corporate banking account → Both may be requested (corporate seal + individual seal of representative)
• M&A or major contracts with overseas corporate counterparts → Corporate seal (formal documentation for inter-corporate transactions)

When in doubt, we confirm destination instructions at engagement and suggest the appropriate certificate type. We can also handle bundles when both individual and corporate seal certificates may be requested.

Seal registration is a prerequisite for obtaining a seal certificate. The registration process differs for individual and corporate seals:

• Individual seal: Register at the municipal office of your residence. Takes anywhere from same-day to one week to receive your seal registration card.
• Corporate seal: Register at the Legal Affairs Bureau, typically in parallel with company incorporation (representative seal filing in the commercial registry).

If overseas relocation timing makes seal registration impractical, alternatives may be acceptable depending on the destination:

• Notarized Signature Block from an overseas entity (subject to destination acceptance)
• Signature Certificate (shomei shomeisho) issued by the Japanese embassy or consulate at your overseas location

Acceptance of these alternatives varies by jurisdiction, so please contact us in advance to check the applicable documentation strategy.

Convenience-store-issued seal certificates can be used for apostille in many cases. Using your My Number card, you can obtain individual seal certificates at major convenience store kiosks (7-Eleven, Lawson, FamilyMart, and others). These certificates are issued in the same official format as those issued at municipal office counters.

This is particularly convenient for:

• Short visits to Japan from overseas (when municipal office hours don't align with your schedule)
• Clients who can't visit during weekday business hours
• Multi-document procurement workflows where convenience store access may be faster than municipal office visits

For clients unfamiliar with the kiosk procedure, our Convenience Store Procurement Support add-on (+¥3,300) provides remote guidance: identification of compatible stores in your vicinity, step-by-step operational guidance, and document quality verification.

Note: Corporate seal certificates (issued by the Legal Affairs Bureau) are handled through Legal Affairs Bureau counters or our procurement service (¥5,500/document + actual costs), rather than convenience store kiosks.

When incorporating a Pte Ltd in Singapore, foreign Director registration may require home-country (Japan) identity and seal verification. The individual seal certificate may be submitted as part of the identity documentation set requested by the Corporate Service Provider (CSP) for ACRA (Accounting and Corporate Regulatory Authority) registration.

Documentation commonly requested by Singapore CSPs includes:

• Individual seal certificate (apostilled) — identity verification of the foreign Director
• Passport copy (sometimes notarized)
• Certificate of Residence (apostilled) — proof of address
• Director consent forms (CSP-provided)

We frequently process seal certificate + Certificate of Residence as a bundle for clients pursuing Singapore incorporation. Documentation varies depending on the CSP — please confirm with your CSP before engaging us.

Timing note: Singapore ACRA or the CSP may request documents issued within 3 months. Reverse-calculate from your incorporation deadline: issuance → apostille → translation → CSP submission. We provide a timeline plan at engagement.

Submitting an overseas departure notification (kaigai tenshutsu todoke) removes you from the residence registry and automatically deactivates your individual seal registration. For overseas residents who need a seal certificate, three options exist:

• Option 1: Re-register during a temporary visit to Japan. Submit a residence registration (transfer-in notification), then re-register your seal, and obtain the certificate. This may be suitable for clients planning overseas company incorporation or real estate transactions.
• Option 2: Use a Signature Certificate (shomei shomeisho) issued by the Japanese embassy or consulate at your overseas location, as an alternative to the seal certificate. Acceptance varies by destination authority.
• Option 3: Use a Notarized Signature Block from an overseas entity (e.g., overseas notary public certification of your signature). Acceptance also varies by destination.

Depending on the timing of your overseas company incorporation or real estate transaction, leveraging a temporary visit to Japan is often a practical choice. Please contact us early so we can plan the documentation strategy.

Note for corporate seals: Corporate seal registration (Legal Affairs Bureau) is unaffected by overseas relocation of individual representatives. The corporate seal remains valid as long as the company is operational and the representative is registered.

The certificate itself has no statutory expiration, but receiving authorities impose their own validity windows. Validity periods tend to be short because seal certificates serve as proof of current identity and contracting authority.

Singapore ACRA or the CSP may request documents issued within 3 months. Plan your timeline backwards from the final submission date, accounting for issuance → apostille → translation → international shipping. We provide a reverse-calculated schedule at engagement.

Because the seal certificate is a public document (issued by a municipal office or Legal Affairs Bureau), the 5 countries we serve fall into two distinct routes:

Route A (the United States / the United Kingdom): Completed with gyoseishoshi's Certification of Translation Accuracy; notary verification is usually not requested, depending on the receiving authority.
Route B (Singapore, New Zealand, and the Philippines): Notary-route verification via Japanese notary public, Legal Affairs Bureau, and MOFA apostille may be requested depending on the receiving authority and document purpose. Singapore ACRA may additionally request notary True Copy certification in some cases.
