Educational guide, not legal advice and not an official service. Not affiliated with the National Police Agency, any police force, the Immigration Services Agency, the Digital Agency, or any railway, airport or taxi company. It can't search for your item; dates are estimates. Rules as of 2026-11-03.
Rules as of 2026-11-03 from 遺失物法 and its cabinet order (e-Gov), the National Police Agency lost-property pages, the Immigration Services Agency residence card page, the Digital Agency My Number page and operators' lost-and-found pages. Periods run from the day an item is handed in, so the dates shown are the earliest, safest ones.
What this is
A free educational guide. It turns a dated reading (as of 2026-11-03) of Japan's Lost Property Act (遺失物法) and its cabinet order, the National Police Agency lost-property pages, the Immigration Services Agency residence card reissue page (入管法 19条の12) and operators' lost-and-found pages into a list of steps, contacts and estimated dates.
What it isn't
Educational guide built from public rules, not legal advice and not an official service. Not affiliated with the National Police Agency, any prefectural police, the Immigration Services Agency, the Digital Agency, any railway, airport or taxi company, or any government body. It cannot search for or find your item; dates are estimates from the legal periods, and the real ones run from the day the item was handed in. Rules as of 2026-11-03.
The legal periods run from the day an item is handed in or publicly notified, which can be later than the day you lost it, so the dates here are the earliest (safest) ones. Operators change phone numbers, hours and storage rules; check their page. For theft, call 110; for non-urgent police consultation, #9110. For immigration questions, ask your regional immigration office.
