​What is a naturalization application?

Non-Japanese citizens can acquire Japanese nationality by naturalization. The Minister of Justice will determine whether or not the foreign national who has submitted the application will be approved.

If the Minister of Justice "permits" naturalization, it will be announced in the "Official Gazette", and the naturalization will take effect from the date of the announcement.

​General conditions for naturalization

5. Those who do not have nationality or should lose their nationality by acquiring Japanese nationality.
