Marriage Registration (婚姻届)

To legally establish a marriage in Japan, you must submit a Marriage Notification Form (Konin-todoke) at any municipal office — your registered domicile, address of residence, or location of stay. Foreign nationals are generally required to obtain a Certificate of Eligibility for Marriage (Kon'in Yoken Gubi Shomeisho) from their home country.

Steps

1

Obtain your Certificate of Eligibility for Marriage from your home country's embassy or consulate in Japan (allow several weeks as it may take time)

2

Obtain the Marriage Notification Form (A3 size) from a municipal office or their website

3

Fill in the form and obtain signatures from 2 adult witnesses (stamp/seal is optional)

4

Submit the completed form with all required documents at any municipal office — your registered domicile, address, or place of stay (many offices accept submissions 24 hours)

5

Once accepted: the marriage is recorded in the Japanese spouse's family register; the foreign national's resident record is updated

6

The 'family status' entry on your Residence Card is updated at the immigration office when you apply for a status change or at your next renewal

⚠️

Important notes

•

For Japanese-Japanese couples, one spouse's surname must be chosen as the marital surname. Foreign spouses generally keep their home country surname

•

Many offices accept submissions 24/7 (use the guard desk on nights/holidays) — formal review occurs the next business day

•

The certificate's name and format vary by country. Korean nationals may substitute with a Family Relations Certificate (Gajok Gwangye Jeungmyeong) + Marriage Record Certificate. Confirm with the municipal office in advance

•

If your home country does not issue this certificate, some municipal offices accept a sworn affidavit or alternative documents — confirm before visiting

•

After the marriage is registered, if you wish to change your visa status to 'Spouse of Japanese National,' you must separately file a Status of Residence Change application
