The “Koseki” family registration system provides official verification of a Japanese person’s name, birth date, spouse, family relationships and other personal information. This registration system has no direct bearing on foreigners. However, births, deaths, marriages and divorces that take place in Japan require the following notifications.
When a Japanese person marries a foreign resident, they must submit various documents, such as a completed marriage notification form, a copy of the Japanese person’s family register, the foreign resident’s passport, a residence card, special permanent resident certificate or foreign resident registration card, which is considered equivalent to these, and a certificate of eligibility for marriage issued by the embassy or consulate office of the foreign resident’s home country. (If the certificate is in a foreign language, then a Japanese translation with the name of the translator must also be attached.) When two foreign residents marry, the procedures are the same.
If a foreign resident living in Japan divorces a Japanese spouse by mutual agreement, they may become legally divorced according to Japanese law. If both parties agree, please submit a completed divorce notification form to the municipal office of either the registered domicile of the Japanese spouse or the city where the person submitting the form has his/her address registered. If both parties are foreign residents, then please inquire with the consulate office of your home country for details concerning the appropriate procedures.

A group of people who share the same home and livelihood is called a household (“setai”). Even if a person is not a family member or if a person lives alone, the unit is still considered a household. The person who provides the main source of living for the household is called the Head of the Household (Setai Nushi). Although household members do not need to be blood-related, friends who are living together are not considered a household member since they have a separate means of support.
