So you want to become a Japanese citizen? These procedures are the domain of the Legal Affairs Bureau (法務局、houmukyoku) which handles naturalization by foreign nationals and other matters to do with citizenship in Japan. You can contact them at any time for questions regarding this.

What is naturalization? If a foreign national (someone without Japanese citizenship) indicates he would like Japanese citizenship, and the Minister of Law (Japanese national government) gives permission, then the foreign national can take Japanese citizenship.

What’s required to become a Japanese citizen?

Some of the major conditions are as follows:

  1. Residency: The foreign resident must have been living in Japan for five or more years consecutively.
  2. Competency: The foreign resident must be of an adult age according to both Japan (20 years of age) and their own country.
  3. Conduct: The foreign resident must be of upright conduct. Criminal records, tax payments, and other societal measures are taken into account when determining this.
  4. Financial independence: The foreign resident must have a stable livelihood. This is determined on a household basis, so if the foreign resident is adequately supported by the assets or abilities of a spouse or relative, then they will fulfill this requirement.
  5. No other nationalities: The foreign resident must have no nationality, or declare they will give up their foreign nationality upon getting Japanese nationality.
  6. Protect the constitution of Japan: A foreign resident who actively plans harm on Japan or is involved in an organization that plans harm on Japan is not eligible for citizenship.

*Conditions are not as strict for persons born in Japan, and for spouses of Japanese nationals.
