Key Points
- A single-status certificate issued by a municipal authority and a certificate of legal capacity to contract marriage issued by a Legal Affairs Bureau or another competent authority differ in issuing authority, certified facts, and typical use.
- For submissions to the United States, the United Kingdom, Singapore, New Zealand, and the Philippines, we handle the authentication route appropriate to the document and Certified Translation into English.
- The document required depends on the country or jurisdiction where the marriage procedure will take place, the marriage-registration authority, and the parties' circumstances.
- The exact document title, issuing authority, recorded particulars, date of issue, and need for additional authentication must be confirmed against the receiving authority's instructions.
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 Consulate-Issued Certificate Plan (¥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, whose professional scope includes preparing and submitting certain administrative 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 a Consulate-Issued Certificate Plan (¥38,500) may apply.
United States
County Clerk's Office · State Authorities Route ANote: as of September 1, 2025, the Embassy of the United States in Tokyo discontinued notarization of Certificates of No Impediment for United States citizens (replaced with a downloadable letter PDF). This concerns the United States side — it has no impact on the Japanese-side certificate covered by this page.
United Kingdom
Register Office · GRO Route ASingapore
Registry of Marriages (ROM) Route BNew Zealand
Department of Internal Affairs Route BPhilippines
Local Civil Registrar · Embassy of Japan Route BWith approximately 340,000 Japanese nationals residing in the Philippines — the largest market we serve. Our practice handles a particularly high volume of Philippines cases and reflects current local procedural updates in our guidance.
Route A and Route B indicate typical workflows only. The final route is not determined solely by the destination country. It is reviewed case by case based on the document, the receiving authority's publicly available guidance or written instructions provided by the client, and current practice at MOFA, notary offices, and other relevant Japanese authorities.
Certificate of No Impediment Process
Issuance Route and Authentication WorkflowA Japanese Certificate of No Impediment to Marriage may be issued by the Legal Affairs Bureau, a municipal office, or a Japanese consulate abroad. Apostille and certified translation requirements may vary depending on the receiving authority. We review the destination country, receiving institution, and issuance route before arranging the proper sequence of procedures.
* Apostille requirements, translation certification format, and original document submission requirements vary depending on the issuing source and receiving authority.

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)
Before advising which document may fit, we review the destination country, receiving authority or marriage office, purpose of submission, intended marriage or filing date, issuance route, and current document status. Email is recommended for written Certificate of No Impediment or single-status related document review and quotation requests. WhatsApp Business may be used for initial overseas inquiries, but formal quotation, document scope, issuance route review, fiancé or partner information review, and written instructions may be handled by email.
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. Because issuance route review may depend on written instructions from the receiving authority, email-based review is recommended where the route is unclear.
| Aspect | Legal Affairs Bureau | Registered Domicile's Municipal Office |
|---|---|---|
| Proxy applications | Not allowed | Varies by municipality |
| Postal applications | Not allowed | Varies by municipality |
| Issuance timing | Depends on office handling | Varies by municipality |
| 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, destination country, and the receiving authority's written instructions. Email-based review is recommended when these instructions need to be confirmed before quotation.
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, formal fiancé or partner information review and written instructions may be handled by email 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 Certificate Plan (¥38,500), 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
- Price: ¥38,500
Our pricing reflects the work scope when the apostille step may be omitted. If you're considering obtaining the certificate at a consulate, request written review by email so we can check whether the consulate-issued route fits your receiving authority before quotation.
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 |
Timing depends on the issuance route, applicant-side collection requirements, municipal office handling, consular issuance, original document status, translation volume, MOFA processing, notary-office and Legal Affairs Bureau availability where applicable, courier schedule, and the receiving authority's requirements. Priority handling is reviewed case by case, and external authority processing times cannot be shortened.
For time-sensitive marriage filings, email-based document review is recommended as early as possible. 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.
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.
Email-based review is recommended when the receiving authority's written instructions, translation format, or notarization route needs to be checked before quotation. For more details, please refer to our Country-by-Country Guide.
