How Do I Register Marriage In Japan?
As a foreign national living in Japan, if you wish to get married under Japanese law, you will need to register your marriage at a municipal office at the current or legal address of the Japanese spouse’s residence.
You must fill out a Marriage Registration form (kon-in-todoke - 婚姻届) at the municipal office. The registration form is available at your local municipal office. The marriage registration form must be signed by two adult witnesses with signatures and Hanko.
Along with the registration, a foreign national must present a Certificate Of Eligibility For Marriage (kon-in-yoken-gubi-shomeisho - 婚姻要件具備証明書).
If you marry a Japanese national overseas, he or she may be required to present a certificate of marriage qualification (kon-in-yoken-gubi-shomeisho - 婚姻要件具備証明書), which is available at the Legal Affairs Bureau's regional branch office (地方法務局).
This certificate is issued by your home country to confirm that you meet the requirements to marry under the laws of your home country. The document can be obtained from your embassy.
