Educational date calculator, not immigration or legal advice; not affiliated with the Immigration Services Agency of Japan or the Ministry of Justice. ISA decides; confirm with your regional immigration bureau before you rely on a date.
Rules as of 2026-11-08 from ISA's 在留期間更新許可申請 page, the 特例期間 explainer, the 在留カード有効期間更新 page, the 特定在留カード Q&A (new card rules from 2026-06-14) and the 2026-10-01 fee table. It works from the dates you type; it cannot see your real card, permit or any decision.
What this is
A free educational date calculator. It applies a dated reading (as of 2026-11-08) of the Immigration Services Agency's pages on extending a period of stay, the special period, renewing a residence card's validity, the 特定在留カード introduced on 2026-06-14 and the residence-permit fees revised on 2026-10-01 to the dates you enter.
What it is not
It is not immigration or legal advice and is not affiliated with the Immigration Services Agency of Japan or the Ministry of Justice. It does not decide whether ISA will grant a renewal, which period ISA will grant, or whether an early application will be accepted. The fee depends on the period actually granted. ISA decides; confirm with your regional immigration bureau, ISA's information centre (0570-013904) or a licensed gyoseishoshi / lawyer.
How dates are counted
"3 months before expiry" is the same calendar day three months earlier (moved to the month's last day when that day does not exist). The special period ends at the end of the day on which two months have passed from the expiry date, counted from the next day. The next permanent-resident card validity assumes a new-format card issued on the date shown. Treat every date as the latest safe day, not a target, and apply with a margin.
