What is a Japanese Certificate of No Impediment to Marriage?
婚姻要件具備証明書 / Konin Yoken Gubi ShomeishoThe Japanese Certificate of No Impediment to Marriage — konin yoken gubi shomeisho (婚姻要件具備証明書) — is the public document a Japanese national may present when marrying abroad, certifying that they meet the requirements for marriage under Japanese law (single status, legal age, no prohibited family relationship, etc.). When you marry under foreign law — for example, in a state of the United States, at a United Kingdom Register Office, or under the Philippines Local Civil Registrar — the receiving authority may request this document to confirm your eligibility on the Japanese side.
There are three issuance routes: the Legal Affairs Bureau (Houmukyoku), your registered domicile's municipal office, or a Japanese consulate abroad. The right choice depends on the destination country and the receiving authority's requirements. Each route also has different procedural constraints, which we walk through below.
Our office is located in Akasaka, Tokyo — within close proximity to the Ministry of Foreign Affairs (Kasumigaseki). We support all three issuance routes with workflows tailored to each, including a half-price package (¥38,500) for consulate-issued certificates where the apostille step may be omitted depending on the issuing and receiving authorities.
A note on terminology: A gyoseishoshi (行政書士) is a Japanese certified administrative procedures specialist licensed under the Gyoseishoshi Act. The profession is a national qualification regulated by the Ministry of Internal Affairs and Communications, with statutory authority to prepare and submit documents to government agencies, including apostille applications.
Certificate of No Impediment vs. Single Status Certificate
Why This Distinction Matters — and How to Recover If You Got the Wrong OneA common point of confusion in international marriage preparation: the Certificate of No Impediment to Marriage and the Single Status Certificate are different documents, despite the similar-sounding names. We regularly hear from clients who registered with a Japanese matchmaking service or dating registry and obtained a Single Status Certificate first. In that situation, we check the receiving authority's instructions before advising whether a Certificate of No Impediment should be obtained separately.
| Aspect | Certificate of No Impediment | Single Status Certificate |
|---|---|---|
| Issued by | Legal Affairs Bureau / municipal office / consulate abroad | Registered domicile's municipal office only |
| What it states | Single status + legal age + fiancé's name, sex, DOB, nationality | Single status only |
| Legal status | Formal capacity-to-marry document under Japanese family law | Simple statement of single status |
| Primary use | Submitted to overseas authorities for marriage | Japanese matchmaking services & dating registries |
| Use by overseas embassies / authorities | May be requested for marriage filings | Usually a different-purpose document |
| Apostille | Yes (via MOFA) | Possible, but the document purpose should be checked before use overseas |
Quick decision guide:
• Marrying abroad in the United States, the United Kingdom, Singapore, New Zealand, or the Philippines → Certificate of No Impediment (may be requested)
• Registering with a Japanese matchmaking service → Single Status Certificate
• Already obtained a Single Status Certificate by mistake → Check whether a Certificate of No Impediment should be obtained separately
• If your receiving authority specifically requests Legal Affairs Bureau issuance → Apply for a Legal Affairs Bureau-issued Certificate of No Impediment (municipal office issuance may not be suitable in such cases)
During case review, we confirm the destination country and receiving authority's instructions, then advise on the document and issuance route. If you've already obtained a different document, we'll guide you through the next steps.
Authentication Requirements by Country
Two Routes — Translator-Certified vs. Notary-VerifiedAuthentication route and translation requirements differ by destination country. The United States and the United Kingdom often use Route A — Translator-Certified Route, subject to the receiving authority's instructions. Singapore, New Zealand, and the Philippines may require Route B — Notary-Verified Route, where requested by the receiving authority. For consulate-issued certificates, the apostille step may be omitted depending on the issuing and receiving authorities, and our half-price package (¥38,500) may apply.

This concerns the United States side — it has no impact on the Japanese-side certificate covered by this page.

7 Common Questions About Certificate of No Impediment Authentication
Frequently Asked QuestionsFor Japanese nationals marrying abroad, the Certificate of No Impediment to Marriage may be requested by the receiving authority, and there are several decision points: distinguishing it from the Single Status Certificate, choosing among three issuance routes, finalizing your fiancé's details, and meeting country-specific translation requirements. Below are seven of the most common questions we receive, along with practical guidance.
Should I get a Certificate of No Impediment to Marriage or a Single Status Certificate?
For international marriage, the receiving authority may request the Certificate of No Impediment to Marriage (konin yoken gubi shomeisho). The Single Status Certificate (dokushin shomeisho) sounds similar but is a different document designed primarily for matchmaking services and dating registries in Japan.
- Certificate of No Impediment to Marriage: Issued by the Legal Affairs Bureau, municipal office, or Japanese consulate abroad. Includes single status + legal age + your fiancé's name and nationality
- Single Status Certificate: Issued only by your registered domicile's municipal office. Certifies single status only (no fiancé information)
If you've already obtained a Single Status Certificate, we check the receiving authority's instructions before advising whether you should obtain a Certificate of No Impediment from the Legal Affairs Bureau or municipal office. We frequently review cases where this distinction was not clear initially.
Legal Affairs Bureau issuance vs. municipal office issuance — which route should I choose?
Requirements vary by receiving authority. Legal Affairs Bureau issuance may be requested by some receiving authorities, while municipal office issuance and Japanese consulate issuance may also be usable depending on the destination and document purpose.
- Some receiving authorities may request Legal Affairs Bureau-issued certificates
- The five jurisdictions we serve — the United States, the United Kingdom, Singapore, New Zealand, and the Philippines — should be checked against the receiving authority's instructions
- We confirm the issuing route before preparing the apostille and translation workflow
The trade-off: Legal Affairs Bureau issuance is handled through in-person collection by the applicant, while municipal offices may allow postal or proxy applications depending on the municipality.
| Aspect | Legal Affairs Bureau | Registered Domicile's Municipal Office |
|---|---|---|
| Proxy applications | Not allowed | Varies by municipality |
| Postal applications | Not allowed | Varies by municipality |
| Same-day issuance | May not be possible | Generally possible |
| Use in the 5 countries | Checked against the receiving authority's instructions | Checked against the receiving authority's instructions |
| Our procurement service | Not available (in-person collection by applicant) | Available (¥5,500 + actual fees) |
The Legal Affairs Bureau handles certificates through in-person collection — can you handle this for me?
Legal Affairs Bureau-issued certificates are handled through in-person collection by the applicant. This is a regulatory restriction under the Family Register Act to prevent fraudulent acquisition, and no third party (including our office) can collect on your behalf.
Here's what we can do to support the surrounding process:
- Pre-visit document checklist (family register, ID, fiancé details, etc.)
- Guidance on the correct spelling of your fiancé's name, including passport spelling and middle-name handling where relevant
- Direction to the right Legal Affairs Bureau office (e.g., the Tokyo Legal Affairs Bureau in Kudanminami)
- Apostille, certified translation, and international shipping after you collect the certificate
If the receiving authority does not request Legal Affairs Bureau issuance, municipal office issuance may be an alternative — we can collect this by power of attorney (¥5,500 per document, plus actual fees). During case review, we check the route based on your circumstances, registered domicile, and destination country.
Do I need to have my fiancé's name and nationality finalized before applying?
The Certificate of No Impediment includes your fiancé's full name, sex, date of birth, and nationality. The certificate is issued for one specific intended marriage; generic certificates for unspecified partners are not possible.
Watch out for these patterns:
- New Zealand fiancé: confirm passport spelling, middle names, and birth certificate details where relevant.
- Filipino fiancé: include the maternal middle name — Filipino names follow a First + Middle + Surname structure that should be captured carefully.
- American fiancé: passport spelling and birth certificate spelling sometimes differ. Confirm what the destination state requests and align to that.
- British fiancé: middle names and spelling variations like -ie vs -y matter; verify against the passport.
If the recorded information is wrong, correction may not be available and a new application may be needed. To reduce that risk, we send a fiancé-information checklist at engagement so we can flag issues before filing.
If I obtain the certificate at a Japanese consulate abroad, do I still need an apostille?
A Certificate of No Impediment issued by a Japanese consulate abroad already carries the consulate's official seal as a representative of the Japanese government, so the MOFA apostille step may be omitted depending on the issuing and receiving authorities.
For consulate-issued certificates, we offer a Consulate-Issued Package (¥38,500 — half of our standard ¥77,000), covering certified translation and submission support only.
- Eligible: Certificates issued by the Embassy of Japan in the United States, the United Kingdom, Singapore, New Zealand, the Philippines, etc.
- Includes: 1 Certified Translation + submission support + 30-day post-delivery requirements check
- Price: ¥38,500 (half of the standard ¥77,000)
Our pricing reflects the work scope when the apostille step may be omitted. If you're considering obtaining the certificate at a consulate, let us know at the quote stage.
Side note: as of September 2025, the Embassy of the United States in Tokyo discontinued notarization of Certificates of No Impediment for United States citizens. That's a separate matter — about documents United States citizens file in Japan — and has nothing to do with the certificate that Japanese nationals obtain at the Embassy of Japan in the United States.
How long is the Certificate of No Impediment valid for marriage filings?
The certificate itself has no statutory expiration, but receiving authorities impose their own validity windows.
| Receiving Authority | Typical Validity |
|---|---|
| State Marriage License (United States) | Varies by state (commonly 30–90 days) |
| Register Office (United Kingdom) | Within 3 months of issuance may be used as a reference by some offices |
| Singapore ROM | Within 3 months of issuance |
| Department of Internal Affairs or other New Zealand authority | Varies by receiving authority |
| Philippines Local Civil Registrar | Within 6 months of issuance may be used as a reference by some offices |
For international marriage, plan your timeline backwards from your planned wedding date, accounting for issuance → apostille → translation → international shipping. The United States is especially variable, so confirming directly with the County Clerk's Office in your destination state is advisable. For the Philippines, timing the certificate close to your Marriage License application may be appropriate depending on the Local Civil Registrar's instructions.
We provide a reverse-calculated schedule at engagement, mapping each step's duration against the submission deadline.
How do the translation requirements differ across the 5 countries?
The 5 countries we serve fall into two distinct routes:
| Country | Route | Notary Public | Primary Use |
|---|---|---|---|
| United States | Route A | Usually not requested | County Clerk's Office (Marriage License) |
| United Kingdom | Route A | Usually not requested | Register Office (Notice of Marriage) |
| Singapore | Route B | May be requested | Registry of Marriages (ROM) |
| New Zealand | Route B | May be requested | Department of Internal Affairs or other authority |
| Philippines | Route B | May be requested | Local Civil Registrar (Marriage License) |
Route A (the United States / the United Kingdom): Often completed with gyoseishoshi's Certification of Translation Accuracy, subject to the receiving authority's instructions.
Route B (Singapore, New Zealand, and the Philippines): May require Japanese notary public, Legal Affairs Bureau, and MOFA apostille steps where requested by the receiving authority.
