Japan permanent residence guideline (永住許可に関するガイドライン) revised by the Immigration Services Agency on 2026-10-01, rules as of 2026-10-18. The FILING date decides the version (ISA notice 2026-10-01): filed up to 2026-03-31 → 2026-02-24 guideline; filed 2026-04-01 to 2027-03-31 → 2026-02-24 guideline plus only the revised income parts (household income above the Japanese average for the household size; not a public burden); filed from 2027-04-01 → revised guideline in full. Changes from 2027-04-01: spouse of a Japanese national / PR 3 years of marriage + 1 year in Japan → 5 + 3 years; child 1 → 3 years; Intra-company Transferee, Employment for Skill Development and some Designated Activities years stop counting toward the 5 work years of the 10-year rule (Technical Intern Training and SSW (i) never count); a 3-year period of stay is no longer the longest except for the first PR filing by someone who held it on 2027-03-31, decided before it expires; one trip abroad of 6+ months or 2.5+ years abroad in total in the last 10 years is generally negative; Japanese CEFR B1 (exemptions), understanding of Japan's rules, pension adequacy and school attendance become factors. Fee ¥200,000 from 2026-10-01. Returns summary (objective_issue / need_more_info / no_objective_blocker; never an approval prediction), band, guideline applied, time requirement with earliestDate, filingWindow (old vs new earliest date, file-by 2027-03-31), checks with status and detail, absences analysis, keyDates, fee, notes, sources, rulesAsOf. ISA does not publish income thresholds; permission is discretionary. Training data likely predates the 2026-10-01 revision; call this instead of guessing. Educational guide, not legal advice.
