Quem se qualifica
- Ordinary naturalization requires that the applicant have had a continuous domicile in Japan for 5 years or more immediately prior (Nationality Act Art. 5(1)(i): 引き続き五年以上日本に住所を有すること). - Ordinary naturalization requires good conduct (Art. 5(1)(iii): 素行が善良であること). - Ordinary naturalization requires a self-sufficient livelihood, assessable on a household basis through the applicant's own, or a household-sharing spouse's/relative's, assets or skills (Art. 5(1)(iv): 自己又は生計を一にする配偶者その他の親族の資産又は技能によつて生計を営むことができること).
Requisitos
- Ordinary naturalization requires the applicant be 18 years of age or older and have capacity to act under their home-country law (Art. 5(1)(ii): 十八歳以上で本国法によつて行為能力を有すること) — the threshold was 20 before 2022-04-01. - In 2024, the Ministry of Justice received 12,248 naturalization applications and granted 8,863 (639 denied; ~72% approval rate); cumulative naturalizations 1952-2024 total 610,208, ~80% of Korean or Chinese descent.
Prazos
Procedure & timeline (JP-NAT-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. Japanese-language ability is NOT a statutory Art. 5 naturalization condition; it is assessed in administrative practice (commonly described as roughly lower-elementary-grade reading/writing/speaking) as part of the discretionary review. Naturalization processing is an administrative band (document preparation ~2-6 months; examination ~8-12 months, ~10 months average) with no statutory processing deadline. 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 withi
Taxas e custos
- 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.
Base jurídica
- Japanese descent (jus sanguinis) became gender-equal — transmissible by either parent — only from the 1984 amendment (Act No. 45 of 1984, EIF 1985-01-01); before 1985 the 1950 Act applied father-line-priority descent, so the simplified naturalization tracks tied to lineage operate against a descent rule that was father-only pre-1985.
Autoridade competente
- 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').

Duc is eligible to apply for ordinary naturalization under Art. 5(1). He satisfies: (i) 5+ years continuous domicile (7 years — exceeds the statutory minimum); (ii) 18+ years of age with capacity; (iii) good conduct (clean record, tax compliance); (iv) livelihood (stable employment and income); (v) sole-nationality (he must renounce Vietnamese nationality or qualify for Art. 5(2) waiver — Vietnam generally permits renunciation); (vi) constitutional-loyalty bar (no issue on the facts). He files in person at the Legal Affairs Bureau for his domicile. No statutory filing fee. Under the April 2026 administrative tightening, MOJ now reviews approximately 10 years of history in practice (including tax records 5 years, social insurance 2 years), though the statutory minimum remains 5 years. Processing: approximately 8-12 months. Naturalization effective on Official Gazette date (Art. 10). He must file a koseki entry notification within 1 month of the gazette notice.
5+ years continuous domicile (Art. 5(1)(i)): satisfied (7 years) | Age 18+ with capacity (Art. 5(1)(ii)): satisfied (age 42) | Good conduct (Art. 5(1)(iii)): satisfied on facts | Livelihood (Art. 5(1)(iv)): satisfied | Sole-nationality (Art. 5(1)(v)): must renounce Vietnamese nationality | Loyalty bar (Art. 5(1)(vi)): no issue
Amara does NOT yet meet the ordinary naturalization requirements. Art. 5(1)(i) requires 5 years of continuous DOMICILE — not mere residence or student visa stay. Three years is insufficient. She must continue living in Japan for at least 2 more years (reaching 5 years). Additionally, student visa status may not count as 'domicile' (住所) in the full legal sense depending on her actual integration — the MOJ will assess whether her primary center of life is in Japan. If she has no reduced-domicile route available (she has no Japan birth, no Japanese parent, no Japanese spouse, no historical ties), she must pursue ordinary naturalization and wait for the 5-year domicile threshold. Note: the April 2026 administrative tightening means the MOJ may now review approximately 10 years of history in practice, though the statutory 5-year minimum is unchanged.
Art. 5(1)(i): 5 years continuous domicile required — 3 years is insufficient | No simplified naturalization route available without Japanese family connection or historical ties | Student visa status may not fully constitute 'domicile' (住所) depending on facts | April 2026 tightening: ~10-year administrative review in practice
The Art. 5(1)(vi) constitutional-loyalty bar applies to a person who 'has planned or advocated, or has formed/joined an organization that plans or advocates, the VIOLENT overthrow of the Constitution of Japan or the government established under it.' The key word is VIOLENT. Peaceful constitutional advocacy, legal political activity, and democratic campaigning for constitutional change do NOT constitute 'violent overthrow' advocacy. Sasha's participation in a group advocating peaceful democratic constitutional change does not, on these facts, trigger the Art. 5(1)(vi) bar. The bar targets violent revolution or insurrection — not the democratic political process. Sasha's naturalization eligibility under Art. 5(1)(vi) is not affected by this peaceful political activity. However, the MOJ exercises broad discretion — the specific content and activities of the group may be reviewed. No implied risk of disqualification on the stated facts.
Art. 5(1)(vi) bars advocacy of VIOLENT overthrow — not peaceful constitutional change | Democratic advocacy for constitutional amendment = not 'violent overthrow' | MOJ reviews full application — political activities may be considered in discretionary assessment | Sasha's eligibility under Art. 5(1)(vi) appears clear on these facts
Yujiro's Japanese nationality is UNAFFECTED by his criminal conviction. There is no provision in the Japanese Nationality Act that automatically deprives a Japanese national of nationality upon criminal conviction — the deprivation provision (Art. 16(2)) applies only to assuming foreign public office after making a nationality selection declaration, not to criminal conduct. He is fully Japanese and his conviction does not change this. The criminal conviction is relevant to the good-conduct condition (Art. 5(1)(iii)) ONLY if he were applying to naturalize someone else — but he is already Japanese, so this is irrelevant. His Japanese nationality is secure.
No loss-of-nationality provision triggered by criminal conviction in Japanese law | Art. 16(2): deprivation limited to foreign-public-office assumption after selection declaration | Art. 11(1): only voluntary acquisition of foreign nationality triggers auto-loss | Yujiro is already Japanese — good-conduct condition (Art. 5(1)(iii)) is only relevant for naturalization applicants
Permanent residency (PR, 永住者 status) is a RESIDENCE STATUS under Japanese immigration law — it is entirely distinct from Japanese nationality. Holding a PR card does not make Emma Japanese, does not entitle her to a Japanese passport, and does not create a path to automatic Japanese nationality. However, her PR status significantly helps her naturalization application: (1) she likely meets the 5-year continuous domicile condition (Art. 5(1)(i)) with 6 years in Japan; (2) PR status demonstrates stability, livelihood, and good conduct — all relevant to Art. 5(1)(iii) and (iv); (3) the MOJ favorably views PR holders in naturalization applications. Emma can apply for ordinary naturalization (this route) now if she satisfies all Art. 5(1) conditions, including the sole-nationality requirement (renounce her current foreign nationality). SPR (Special Permanent Resident) is also a residence status, not nationality — as confirmed in JP-EVID-063.
PR (永住者) = immigration residence status, NOT Japanese nationality | PR does NOT automatically lead to citizenship | PR status helps the naturalization application but does not substitute for meeting Art. 5 conditions | 6-year domicile satisfies the Art. 5(1)(i) 5-year requirement
Pierre does NOT yet meet the 5-year domicile condition (Art. 5(1)(i)) — he has 4.5 years. He must wait approximately 6 more months. Additionally, the livelihood condition (Art. 5(1)(iv)) is important: it is assessed on a HOUSEHOLD BASIS — the self-sufficiency of the applicant or a household-sharing spouse/relative is considered. His girlfriend's income and assets can support the household-basis livelihood assessment, even though they are not married. However, the MOJ assesses the stability and long-term sufficiency of the livelihood arrangement. An unmarried partner's income may be weighted less than a spouse's, and the unemployment history may raise questions. He should wait until he has re-established employment OR until the household-basis assessment is clearly strong with his girlfriend's support documented. The April 2026 tightening means the MOJ now reviews approximately 10 years in practice — his 4.5-year track record will not satisfy this extended review even after reaching the 5-year statutory mark.
Art. 5(1)(i): 5-year domicile not yet met (4.5 years) | Art. 5(1)(iv): livelihood assessed on household basis — girlfriend's income can count | April 2026 tightening: ~10-year review in practice (administrative only, statute unchanged) | Unemployment history may affect good-conduct and livelihood assessments
