Getting Married in Japan
A Complete Guide for International Couples
Marrying a partner of a different nationality in Japan involves more paperwork than a marriage between two Japanese nationals — and the process differs depending on where you register first. This guide covers both routes, the documents you'll need, and what to do about your visa afterward.
- The two paths: registering in Japan first, or registering abroad first
- 婚姻要件具備証明書 (Certificate of No Impediment) — what it is and how to get it
- Required documents, and how they differ by nationality
- Marriage alone doesn't change your visa — what to do next
- Reporting your marriage to your home country too
- Same-sex couples: the current legal situation in Japan
Based on official municipal (市区町村役場) procedures and consular guidance. Requirements vary by nationality — always confirm specifics with your embassy and local municipal office. Last updated: August 2026.
Two Ways a Marriage Becomes Legal Across Two Countries
When one or both partners hold a nationality different from where you're registering, your marriage needs to be legally valid in both countries involved. Japan handles this through two different processes depending on where you register first.
Which Path Applies to You?
Most international couples living in Japan register their marriage in Japan first — it is generally the simpler route when at least one partner is already resident here.
Path 1: Registering in Japan First
Path 2: Registering Abroad First, Then Reporting to Japan
If you married under the law of the foreign partner's country (or a third country), you must report the marriage to a Japanese municipal office or overseas Japanese diplomatic mission within 3 months of the marriage date, along with the foreign marriage certificate and its Japanese translation. Missing the 3-month window doesn't invalidate the marriage but does require an additional explanatory document at the time of the late report.
Documents Required to Register in Japan
Exact requirements vary by nationality — always confirm with your embassy and the specific municipal office you'll be filing at, since some offices interpret requirements slightly differently.
| Document | From | Notes |
|---|---|---|
| 婚姻届 (Marriage registration form) | Municipal office (free) | Both partners complete it; 2 adult witnesses sign |
| 婚姻要件具備証明書 (Certificate of No Impediment) | Foreign partner's embassy/consulate in Japan | Some countries don't issue this — an affidavit sworn before consular staff may substitute |
| Passport | Foreign partner | For identity confirmation |
| 戸籍謄本 (Family register) | Japanese partner's registered municipal office | Not needed if filing at the same office where the Japanese partner's 本籍 is registered |
| Japanese translation of all foreign-language documents | Any translator (self-translation accepted) | Translator's name must be printed on the translation |
Countries including India and Peru have no legal mechanism to issue this certificate. In these cases, a sworn affidavit before consular officials, or additional supporting documents, may be accepted instead — confirm the specific alternative with both the embassy and the municipal office in advance.
Reporting Your Marriage to Your Home Country
Japanese municipal offices do not automatically notify any other country's government when a marriage is registered. If you don't report the marriage yourself, it may not exist in your home country's official records — which can cause problems later for inheritance, name changes, or your own country's spouse visa/residency applications if you ever return.
This certificate, issued by the municipal office where you registered, is typically the core document you'll need to report the marriage to your embassy or home country's civil registry. Procedures and required documents vary significantly by country — contact your embassy in Japan directly for their specific process.
Marriage Doesn't Automatically Change Your Visa
Registering your marriage is a family-law matter handled by the municipal office. Your Status of Residence is a separate, immigration-law matter handled by ISA. Getting married does not automatically switch you to a Spouse Visa, and — importantly — it's not required to.
If you're already in Japan on a valid work or student visa, you can continue on that status after marrying a Japanese national. Many couples switch to a Spouse Visa because it removes work restrictions entirely, but there's no deadline forcing you to do so.
If you do want to switch, you'll need to file a Change of Status application with your marriage certificate/受理証明書 as supporting evidence. If your foreign partner is currently outside Japan on a marriage visa track (i.e., entering Japan for the first time as a spouse), the process instead goes through a Certificate of Eligibility (COE) application from Japan, followed by a visa application at the embassy abroad.
👫 Full Spouse Visa Requirements Guide →Same-Sex Couples — The Current Legal Situation
As of August 2026, Japan's Civil Code and Family Registration Act are interpreted by the national government as not permitting marriage between two people of the same registered sex — municipal offices do not accept a 婚姻届 from same-sex couples. Several high court rulings in 2024–2025 found the current legal framework unconstitutional, but no national legislation has changed as a result.
Many municipalities (covering the large majority of Japan's population) offer a パートナーシップ制度 (partnership certificate) for same-sex couples. These can help with things like hospital visitation rights or public housing applications in some areas, but they are not a legal marriage and do not, by themselves, qualify a foreign partner for a Spouse Visa or any other status of residence.
If you're a same-sex couple with one partner needing a Japan visa, your options depend heavily on your specific circumstances (existing work/study eligibility, nationality, etc.). This is a genuinely complex area with no standard path — a consultation with a specialist familiar with these cases is strongly recommended before making any plans.
