Rules changed. Effective April 1, 2026 the minimum residency rose from 5 to 10 years, tax verification to 5 years and social insurance to 2 years. The document set below still anchors on the long-standing Article 5 framework; confirm which regime applies to you with your Legal Affairs Bureau.

The five moves, in order

Year 0–5 · Domicile ·

Bank the residency — cleanly

Hold a valid status of residence for 5 continuous years (10 from April 2026), at least 3 of them on a work-eligible status. Pay every tax and pension instalment on time, keep traffic violations at zero, and avoid single trips abroad over ~90 days (or ~150 cumulative days/year) that reset the clock. Build everyday Japanese toward JLPT N3+.

Month −6 to −3 · Documents ·

Gather the 12 document categories

The longest phase. Order Japan-side records first, then India-side source documents — every India document needs MEA apostille plus a certified Japanese translation (allow 6–10 weeks). Hand-write your statement of purpose () and resume in Japanese.

Before you file · Readiness ·

Score your readiness honestly

"Good conduct" () and "ability to secure a livelihood" () are judged holistically. Clear any red flag first: tax arrears or unfiled returns, license suspensions, thin or unstable household income, weak Japanese, or undecided dual-citizenship intent.

Month 0–14 · Procedure ·

File in person, then run the gauntlet

Submit at your Legal Affairs Bureau in person (no fee). Expect a 30–90 minute interview (with spouse if married), possible unannounced home and workplace visits, and behind-the-scenes verification with your city office, employer and police in both countries. The Minister of Justice decides, effective on the announcement.

At approval · India-specific ·

Settle the Indian side

India bars dual citizenship — Japanese nationality automatically ends your Indian citizenship (Citizenship Act, 1955, s.9). Surrender your Indian passport for a Renunciation Certificate, then apply for an OCI card as the lifelong-access fallback. Keep Indian returns current and use the India–Japan DTAA.

The 12 document categories

  • Application core forms & written oath
  • Hand-written reason (動機書) & resume
  • Proof of financial stability / livelihood
  • Employment & income certificates
  • Tax filings (withholding, residence, income)
  • Pension & social-insurance record
  • Identity & residence (Japan) — jūmin, zairyū
  • Entry/exit history (ISA disclosure)
  • Identity & nationality (India) source docs
  • Police clearance certificate (PCC)
  • Education & professional / driving record
  • Maps & visual proof (home, work, photos)

When your passport is Indian

  • Loss of citizenship: Japanese nationality ends Indian citizenship automatically — surrender the passport, get a Renunciation Certificate.
  • OCI fallback: apply for an Overseas Citizen of India card for lifelong visa-free entry (not citizenship; no vote).
  • Apostille: birth cert, parents' marriage, diplomas, PCC, status affidavit — MEA apostille + certified Japanese translation.
  • Tax both sides: file Indian returns up to the year of naturalization; use the India–Japan DTAA to avoid double taxation.
Three milestones to plan for: (A) in-person submission, (B) possible home & workplace visits, (C) the Minister's decision & Kanpō announcement.

Criteria are applied case-by-case by the Legal Affairs Bureau and the Ministry of Justice; day thresholds and document lists are guideline figures and change over time (note the April 2026 rule change).
