Key Points
- “Single Status Certificate,” “Certificate of No Impediment,” and Japanese terms such as 独身証明書 / 婚姻要件具備証明書 are not reliable one-to-one labels; the requested content and issuer must be identified from the receiving authority's instructions.
- For Japanese nationals marrying under a foreign country's procedure, a marriage-eligibility certificate may be issued by a Legal Affairs Bureau, a municipal office, or a Japanese diplomatic mission depending on the circumstances and the receiving authority's requirements.
- A municipal matchmaking/service single-status certificate and a marriage-eligibility certificate serve different functions, although terminology is sometimes used loosely by authorities.
- Apostille, translation, submission format, document age, and issuer requirements depend on the actual document and the receiving authority.
Japanese Marriage-Eligibility and Single-Status Documents
婚姻要件具備証明書 · 独身証明書 · Case-Specific IdentificationFor a Japanese national marrying under a foreign country's procedure, the marriage authority may request a Japanese document showing eligibility to marry under Japanese law. The English or Japanese label alone does not identify the required document. We first confirm what the receiving authority is actually requesting, who must issue it, and what facts it must certify.
Depending on the applicant's situation and the receiving authority's requirements, a relevant Japanese certificate may be issued by a Legal Affairs Bureau, a municipal office, or a Japanese diplomatic mission overseas. These are not interchangeable routes: the issuing authority, the certified facts, the form, and the subsequent authentication handling differ, and some receiving authorities accept only a certificate from a specific issuer.
A note on terminology: A Gyoseishoshi (行政書士) is a Japanese national qualification under the Gyoseishoshi Act. Within the scope permitted by Japanese law, a Gyoseishoshi may prepare and submit certain documents to government agencies and handle related administrative procedures.
Similar Names, Different Documents
“Single Status” Does Not Identify One Universal Japanese CertificateJapanese public authorities themselves use these terms with some variation. A municipal single-status certificate (独身証明書) exists as a certificate of current unmarried status, commonly used for matchmaking and marriage-information services in Japan. Separately, a marriage-eligibility certificate (婚姻要件具備証明書) exists for Japanese nationals marrying under a foreign country's procedure. At the same time, some authorities and foreign-facing materials informally refer to a marriage-eligibility certificate as a “single status certificate,” so the terminology overlaps in practice.
For that reason, we do not treat the two names as automatically identical or automatically different. What the receiving authority actually requests — the certified content and the required issuer — controls which Japanese document applies. Where the instructions are ambiguous, the receiving authority's written requirements should be confirmed before any document is obtained or authenticated.
Relationship to the family register. A family register (koseki) is not automatically the same document as a marriage-eligibility certificate or a single-status certificate. The receiving authority may request the family register itself, the family register may serve as supporting evidence when another certificate is issued, and in some procedures the receiving authority may request a family register with a translation instead of another certificate. We do not determine, as a matter of foreign law, which document a foreign marriage authority must accept; the receiving authority's exact current instructions control.
Receiving-Authority Considerations
Current Service Scope: United States, United Kingdom, Singapore, New Zealand, and the PhilippinesThe destination country alone does not determine which document is required, who must issue it, whether an apostille is required, or how it must be translated. The receiving marriage authority's current instructions control, and those instructions may differ between offices and procedures within the same country.

Receiving Authorities and Procedures Vary Case-SpecificThe receiving authority's current written instructions, the requested document and issuer, the required submission format, and the actual authentication and translation requests are confirmed before any Japan-side step is arranged.
Document and Authentication Review
Authentication Depends on the Exact CertificateBefore any Japan-side step is arranged, we confirm four points: the exact document requested, the issuing authority, the receiving authority, and the authentication actually requested. The document name alone does not determine the authentication route.
Domestic public documents. A marriage-eligibility certificate or single-status certificate issued by a Legal Affairs Bureau or a municipal office may be eligible for a direct MOFA apostille where the receiving authority actually requires one and the document satisfies MOFA's current requirements, including document-age requirements.
Diplomatic-mission-issued certificates. A certificate issued by a Japanese embassy or consulate overseas is not handled as a standard Japan-issued document for a MOFA apostille: documents executed by diplomatic or consular agents fall outside the scope of the Hague Apostille Convention. Its acceptance, or any additional local procedure, must be confirmed with the receiving authority and the relevant diplomatic mission.
Translation. Certified Translation is prepared only where the receiving authority separately requires it. The required language and any translator-certification format follow the receiving authority's current instructions.
No added authentication. If the receiving authority does not request an apostille or other authentication for the document, no authentication step should be assumed or added.

Eight Practical QuestionsThese questions address terminology, issuing authorities, acquisition, recorded partner information, consular issuance, apostille requirements, translation, and the initial inquiry.
Is a Single Status Certificate the same as a Certificate of No Impediment to Marriage?
Not necessarily — and the names do not map one-to-one. A municipal single-status certificate (独身証明書) exists as a certificate of current unmarried status, commonly used for matchmaking services in Japan, while a marriage-eligibility certificate (婚姻要件具備証明書) exists for Japanese nationals marrying under a foreign country's procedure. At the same time, some authorities informally call a marriage-eligibility certificate a “single status certificate.”
The English or Japanese label alone does not identify the required document. We first confirm what the receiving authority is actually requesting, who must issue it, and what facts it must certify.
Who can issue a Japanese marriage-eligibility certificate?
Depending on the applicant's situation and the receiving authority's requirements, a relevant certificate may be issued by a Legal Affairs Bureau, by the municipality of the registered domicile, or by a Japanese embassy or consulate overseas.
These are not interchangeable: the issuing authority, certified facts, form, and subsequent authentication handling differ, and some receiving authorities accept only a certificate from a specific issuer. The issuer should be confirmed against the receiving authority's instructions before applying.
Can your office obtain the certificate for me?
Legal Affairs Bureau applications are generally applicant-handled; the current instructions of the relevant bureau, including required identity documents and family-register certificates, should be confirmed. For municipal issuance, application conditions and any proxy or postal availability vary by municipality.
Where acquisition assistance is legally and operationally available, availability and any separate professional fee are confirmed individually. Our Japan-side support otherwise covers document review, authentication handling where required, Certified Translation where required, and delivery.
Does the certificate need information about my future spouse?
Some certificate forms record the intended spouse's particulars, such as name, sex, date of birth, and nationality, and the issuing authority may require that information at application. The required fields and format depend on the issuer and, ultimately, on what the receiving authority expects the certificate to show.
Where recorded details turn out to be inaccurate, correction may not be available and a new application may be needed. Confirm the issuing authority's current instructions — including how names should be written — before applying.
What if I obtain the certificate from a Japanese embassy or consulate overseas?
Japanese diplomatic missions may issue marriage-eligibility certificates under mission-specific procedures based on family-register information. The exact form, language, and required applicant or partner information vary by mission.
A mission-issued certificate is outside the standard Hague apostille route, because documents executed by diplomatic or consular agents fall outside the Convention's scope. Its acceptance, or any additional local procedure, must be confirmed with the receiving authority and the relevant mission, and such matters are reviewed separately from our standard Japan-side packages.
Does a Japanese marriage-eligibility certificate always need an apostille?
No. Whether an apostille is required depends on the exact document, the issuing authority, and the receiving authority's current instructions.
An eligible domestic public document may receive a MOFA apostille where one is actually required and the document satisfies MOFA's current requirements. If the receiving authority does not request an apostille or other authentication, no authentication step should be assumed or added.
Do I always need a Certified Translation?
No. Certified Translation is prepared only where the receiving authority separately requires it, and the required language and any translator-certification format follow the receiving authority's instructions.
Where required, Japanese-to-English Certified Translation for eligible civil-status documents starts from ¥33,000, with volume, complexity, and additional documents quoted separately.
What information should I send for an initial inquiry?
Please provide the destination country, receiving authority, document, desired deadline, and whether the document has already been issued.
After the initial scope review, we may follow up on the issuing authority, partner information required by the issuing authority, the exact certificate wording, and the document's issue date where relevant. Email is recommended where written requirements need to be reviewed; WhatsApp may be used for initial overseas inquiries, and LINE is available for clients residing in Japan.
