TRAIN LOST AND FOUND
Japan train lost and found: a traveler checklist
How to report an item lost on a Japan train, what details operators need, and what changes when an item is transferred to police.
Last verified: July 2026
Short answer
Contact the railway operator quickly and provide the travel date, line, boarding and exit stations, train time, car number, seat, and item details. Storage periods and handoff rules vary. Tokyo Metro, for example, says items are normally moved to its Lost & Found Center and later transferred to the Metropolitan Police Department.
What to do
- 1
Identify the operator
A station may serve JR, Metro, and private railway lines. Use your ticket, route history, or map timeline to identify the company that operated the train.
- 2
Reconstruct the journey
List the date, approximate time, line, direction, boarding and exit stations, transfers, car number, seat, and where the item may have been left.
- 3
Contact the operator promptly
Report the item through the operator's official lost-and-found channel. JR East provides an information line that accepts calls from overseas; other operators have separate channels.
- 4
Prepare for a police transfer
If the operator transfers the item to police, the collection location and documents may change. Tokyo Metro says third-party collection requires authorization and identity documents.
Frequently asked questions
