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

The Core Distinction

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.

① Marry in Japan first
創設的婚姻 (Creating the marriage in Japan)
You submit a 婚姻届 (marriage registration form) at a Japanese municipal office. This is the marriage's origin point — it doesn't exist yet in your home country's records until you report it separately.
Most common route
② Marry abroad first
報告的婚姻 (Reporting an existing marriage)
You already legally married under your home country's law (or a third country's). You then report this marriage to a Japanese municipal office or overseas Japanese embassy/consulate within 3 months.
For couples who married overseas
Step One

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


Step 1
The foreign partner obtains a 婚姻要件具備証明書
A Certificate of No Impediment to Marriage (or an equivalent document) issued by the foreign partner's embassy or consulate in Japan, confirming they are legally free to marry under their home country's law. Requirements and processing time vary significantly by nationality — some embassies require a birth certificate or affidavit of eligibility first.

Step 2
Prepare and translate documents
The certificate (and any supporting documents in a foreign language) must be translated into Japanese. Any adult can act as translator — there is no requirement to use a certified translation service — but the translator's name must appear on the translation.

Step 3
Submit the 婚姻届 at a municipal office
File at any municipal office in Japan (does not need to be your registered address). Two adult witnesses (any nationality) must sign the form. Bring passports for identity confirmation.

Done — same day in most cases
Marriage is legally registered in Japan
Once accepted, the marriage is legally valid in Japan immediately. Request a 受理証明書 (certificate of acceptance) — you'll need it to report the marriage to your home country.

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.

What You Need

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
⚠️ Some nationalities can't get a Certificate of No Impediment

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.

Don't Skip This

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.

💡 Request a 受理証明書 (Certificate of Acceptance) when you register

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.

What Comes Next

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.

✅ Switching to a Spouse Visa is optional, not mandatory

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.

Important Context

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.

💡 Local partnership certificates exist, but carry no immigration weight

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.

Frequently Asked

Getting Married in Japan — FAQ

Reviewed by a licensed Administrative Scrivener based on real cases.

No. Marriage registration and your Status of Residence are separate matters. You can remain on your current work or student visa indefinitely after marrying — switching to a Spouse Visa is a choice, not a requirement. Many people switch because Spouse Visa removes work restrictions, but there's no deadline forcing the change.
A small number of countries (including India and Peru) have no legal mechanism to issue this document. In these cases, the embassy typically provides a sworn affidavit process instead, or the municipal office may accept alternative supporting documents. Contact both your embassy and the specific municipal office in advance — the accepted alternative can vary by office.
Yes — you need to report (not re-register) the marriage to a Japanese municipal office or overseas Japanese embassy/consulate within 3 months of your marriage date abroad, along with the foreign marriage certificate and its Japanese translation. This is a report of an already-valid marriage, not a new registration.
A foreign national marrying a Japanese national does not automatically join the Japanese partner's family register (戸籍) or take their surname, since foreign nationals aren't entered into a Japanese koseki. If you want to use your partner's surname in Japan for daily life (bank accounts, name on your residence card, etc.), separate procedures apply — ask your municipal office about the options available, which are more limited than for two Japanese nationals marrying.
If your embassy can issue the Certificate of No Impediment quickly and all documents are in order, the municipal office filing itself can be completed same-day. The bottleneck is almost always the embassy document — some embassies take days, others take several weeks, particularly if they require documents to be sent from your home country first. Start the embassy process as early as possible.

Start with your partner's embassy — that's the bottleneck

Most delays come from waiting on the 婚姻要件具備証明書. Contact the embassy first, then come back for the municipal office steps and what to do about your visa afterward.
