- Notes
- Standard naturalisation is governed by Japan’s Nationality Act: the applicant must generally have been domiciled (or resident) in Japan for five (5) or more consecutive years and must have held a valid status of residence throughout the prescribed period. Permanent Resident (PR) status is not a prerequisite. The Minister of Justice may permit naturalisation with relaxed residence requirements in statutory cases, including for spouses of Japanese nationals (e.g., 3 years domicile/residence in Japan; or 3+ years marriage and 1 year domicile in Japan), and other categories set out in the Act (e.g., child of a person who was a Japanese national, born in Japan, long residence, etc.). The process is typically initiated through appointment-based consultation at the Legal Affairs Bureau (法務局) that has jurisdiction over the applicant’s address; required documents are specified case-by-case and can be extensive. Japanese language ability is not stated as a JLPT level in the Act, but functional Japanese is typically necessary for consultations/interviews and Japanese paperwork.
