The path to Japanese citizenship,
mapped end‑to‑end.
An interactive roadmap for Indian passport holders pursuing kika (帰化) — Japanese naturalization. Built around the Nationality Act's five-year continuous-residency baseline (→ see the 2026 update note, right). Track your residency, prepare every Ministry of Justice document, assess readiness, and walk through each step from Legal Affairs Bureau consultation to Official Gazette announcement.
01 · Domicile · 住所要件
Track your continuous residency
Article 5(1)(i) of the Nationality Act requires you to have been domiciled in Japan for five consecutive years on a valid status of residence. Enter your first arrival date — we'll compute progress, your earliest application window, and the breaks that could reset the clock.

What counts as "continuous"?
- Single trip abroad > ~90 days — likely breaks continuity.
- Cumulative absences > ~150 days in a year — typically resets the clock.
- Status lapses — any period without a valid status of residence does not count.
- Reset — if continuity is broken, the 5- (or 10-) year count restarts from your re-entry on a valid status.
Per Ministry of Justice — Nationality Q&A. Day thresholds are guideline figures used by Legal Affairs Bureaus and are applied case-by-case.

The mandatory document set
Twelve official categories from the Ministry of Justice, plus the India-specific source documents you'll need to gather from home. Check items off as you complete them to see your progress.
03 · Readiness · 適格性審査
Pre-application self-assessment
The MOJ evaluates "good conduct" (素行) and "ability to secure a livelihood" (生計) holistically — there's no published rubric. This assessment scores you on the factors that case officers actually probe during interviews.
04 · Procedure · 申請手続
The Ministry of Justice process, step by step
From your first consultation at the Legal Affairs Bureau to the Official Gazette announcement and your new koseki — every milestone, what happens at each, and the questions case officers actually ask.
Three critical milestones to plan for
B
Home & workplace visits
A case officer may visit your residence and workplace unannounced. They verify you actually live and work where you claim — checking closets, meeting spouses, talking to colleagues. Cooperation is informally mandatory.
C
Final decision
The Minister of Justice issues permission. Naturalization takes legal effect on the date the announcement is published in the Kanpō (Official Gazette). Total time from submission: typically 8–14 months, but 1–2 years is not unusual.
05 · India-specific · インド国籍者向け
What's different when your passport is Indian
India does not permit dual citizenship. Acquiring Japanese nationality automatically terminates your Indian citizenship under the Citizenship Act, 1955. Plan the paperwork on both sides.
🇮🇳 Loss of Indian citizenship
Section 9 of the Indian Citizenship Act, 1955 provides that any citizen of India who voluntarily acquires the citizenship of another country ceases to be a citizen of India. You must surrender your Indian passport at the nearest Indian Mission and obtain a Renunciation Certificate.
Citizenship Act, 1955 — MHA →📄 OCI as a fallback
Former Indian citizens can apply for an Overseas Citizen of India (OCI) card after naturalization. OCI grants lifelong visa-free entry to India and most residency-style rights, but is not citizenship and does not restore voting rights.
OCI Services portal →🗂️ India documents to apostille
- Birth certificate (with parents' names)
- Parents' marriage certificate
- Educational diplomas (10th, 12th, degree)
- Police clearance certificate from PSK
- Affidavit of single/marital status (if relevant)
All India-issued documents typically need MEA apostille and certified Japanese translation. Allow 6–10 weeks.
🏛️ Tax in both jurisdictions
If you still have Indian-source income (rent, dividends, capital gains), file your Indian returns up to and including the year of naturalization. Use the India–Japan DTAA to avoid double taxation. Japan will ask for proof of all foreign income on your livelihood documents.
