Answer

Naturalisation means that a foreign national acquires Japanese nationality with the permission of the Minister of Justice. There are 3 kinds: 普通帰化, 簡易帰化 and 大帰化. The procedure starts with a consultation at the Legal Affairs Bureau, then goes through preparing documents, applying, an interview and screening, before permission is given. The screening can take 1 year or more.

What is naturalisation?

It means acquiring Japanese nationality with the permission of the Minister of Justice.

When naturalisation is granted, that person becomes a Japanese national and carries the same rights and duties as any other Japanese person. For someone who loves life in Japan and wishes to live as a Japanese person, this is a major decision in life.

What kinds of naturalisation are there?

There are 3: 普通帰化, 簡易帰化 and 大帰化.

普通帰化 (ordinary naturalisation)

This is naturalisation for foreign nationals in general. When people say naturalisation, they usually mean 普通帰化.

簡易帰化 (simplified naturalisation)

If you have a close connection with Japan, for example because you are married to a Japanese person or were born in Japan, some conditions are relaxed or waived. This covers 特別永住者 (special permanent residents), and foreign nationals married to a Japanese person.

大帰化 (grand naturalisation)

This is for foreign nationals who have rendered special service to Japan, and it is done with the approval of the Diet. There are no clear requirements, and it is said that no case has ever been granted.

What changes when naturalisation is granted?

As a Japanese national, you receive the full rights and the full social security of Japan.

How does the procedure go?

It starts with a consultation at the Legal Affairs Bureau, then goes through an interview and screening before permission is given.

  1. Consultation at the Legal Affairs Bureau
    First you talk to the Legal Affairs Bureau, and they explain the required documents and the procedure.
  2. Preparing the documents
    You gather what you need: the application form, a certified copy of the family register, proof of income, a residence certificate and so on.
  3. Filing the application
    You file it with the Legal Affairs Bureau.
  4. Interview
    You have an interview with an officer of the Legal Affairs Bureau.
  5. Screening
    The Minister of Justice carries out the screening. This can take 1 year or more.
  6. Permission
    Once permission is given, it is published in the 官報 (Official Gazette).

Is there anything to be careful about?

The screening is strict, and preparing the documents takes time.
