Japan-born stateless person (simplified naturalization)

• Japan-born stateless simplified naturalization (Art. 8(iv)): a person born in Japan who has been STATELESS since birth, with 3+ years' continuous domicile since birth, may be naturalized with Art. 5(1)(i), (ii) and (iv) conditions waived. - Positive N/A on the conventions — Japan is a non-party to the 1954 Convention relating to the Status of Stateless Persons, the 1961 Convention on the Reduction of Statelessness, and the 1957 Convention on the Nationality of Married Women (depositary-verified); there is no treaty-based statelessness route to nationality. - Despite non-party status to the statelessness conventions, Japanese domestic law provides limited statelessness safeguards: Art. 2(iii) confers nationality at birth on a child born in Japan whose parents are both unknown or stateless, and Art. 8(iv) provides simplified naturalization for a Japan-born person stateless since birth with 3+ years continuous domicile.

Procedure & timeline (JP-SPC-01): A naturalization application is filed in writing, in person, through the (District) Legal Affairs Bureau with jurisdiction over the applicant's domicile (or via a diplomatic/consular post if abroad); for an applicant under 15 the statutory agent applies on their behalf (Enforcement Reg Art. 2; Nationality Act Art. 18). From 1 April 2026 the Ministry of Justice raised the practical naturalization screening standards (residence history reviewed to ~10 years; tax certificates 5 years; social-insurance confirmation 2 years) by administrative revision; the Art. 5(1)(i) statutory minimum of 5 years' domicile is UNCHANGED. When naturalization is permitted, the Minister of Justice publishes a public notice (告示) in the Official Gazette (官報), and the naturalization takes legal effect on the date of that gazette notice (Art. 10(1)-(2)). After naturalization takes effect on the gazette-notice date, the new Japanese national must file a notification of naturalization for koseki entry within 1 month (Family Register Act Art. 102-2), creating or joining a family register. Any supporting document in a foreign language submitted with a naturalization application must be accompanied by a Japanese translation that identifies the translator (Enforcement Reg Art. 5). There is no statutory filing fee for a naturalization application; the application itself is free of charge, with applicants bearing

• There is no statutory filing fee for a naturalization application; the application itself is free of charge, with applicants bearing only ancillary document-procurement and translation costs.

Primary legal authorities: Nationality Act Art.8(iv), Art.5(2). Status: Operative (—present). Administering authority: Ministry of Justice (法務省), Civil Affairs Bureau, via the Legal Affairs Bureaus (法務局); consular missions (外務省) for notifications/applications filed abroad. Person born in Japan who has been stateless since birth and has 3+ years continuous domicile may naturalize without the age/livelihood conditions (Art.8(iv)). Complements Art.2(iii); Japan is non-party to the statelessness conventions.

• Naturalization requires the permission of the Minister of Justice and is discretionary: even where all statutory conditions are met, naturalization is not conferred as of right (Art. 4: 帰化によつて日本の国籍を取得することができる / requires MOJ permission; Art. 5 'may not permit unless').
