Japan Lost and Found Guides for Travelers
Japan's lost property system works, but it is split between police, railway operators, taxi companies, airports, hotels and individual venues — and almost all of it runs in Japanese. These ten English guides explain who actually holds your item, how long they keep it, and what you have to do to get it back.
What to do first
- Retrace your journey and contact the exact operator or venue. Restaurants, shops and hotels often hold an item themselves for a day before passing it to police, so it may not be in any official system yet.
- Report the loss to the police where appropriate. A lost item report (遺失届) at a koban is free and quick, though availability varies — if the box is unattended, contact the local police or use a police station. The report is what connects a found item back to you. Some embassies ask for it before a passport application, so confirm the order with them.
- Protect your accounts if a device or card is missing. Cancel bank cards immediately, and treat phone, SIM and email access as urgent.
- Confirm ownership documents, the collection deadline and shipping options with the actual holder. Which paperwork is accepted, how long the item is held and whether it can be posted abroad are decided by the organisation holding it.
