Application for Naturalization in Japan

The application for naturalization should be submitted to the Minister of Justice at regional or district Legal Affairs Bureau of the Ministry of Justice.

It is necessary to sub­mit various types of document, and it is therefore advisable to consult with the Legal Affairs Bureau.
It should be stressed that naturalization is not necessarily granted,even all the conditions described earlier have been satisfied; fulfillng them only entitles you to apply.
A person who is granted naturalization and has thus obtained Japanese nationality must register at the municipal office of the city,town or village in which the person is living,or in the case the person is outside of Japan,at the Japanese consulate abroad.

Upon notification,he will be entered in the family registry as a Japanese national.
