The Lost Property Process in Japan
Step 1: Realize and Recall

- Stop and retrace your steps mentally
- Check your recent locations — where did you last definitely have the item?
- Check with your hotel front desk (guests often leave items in rooms)
Step 2: Check the Nearest Koban
Japan's koban system is the backbone of the lost-and-found network:
- Visit the koban nearest to where you last remember having the item
- Describe the item in detail (color, brand, contents, distinctive features)
- Leave your name and hotel contact information
- The officer will log the item and contact you if it is found
Step 3: Check Transportation Lost Property
If you lost the item on public transport, contact the relevant company's lost property office. Items found on trains are typically:
- Held at the station where found for 3-5 days
- Transferred to the railway's central lost property center
- Held for 14-30 days before being donated or sold
Step 4: Check the Central Lost Property Center
Items not claimed at koban within 7 days are sent to:
- Kanagawa Prefectural Police Lost Property Center: 045-211-1100

- Unclaimed items after 3 months are either returned to the finder or auctioned

Practical notes for visitors
Japan's lost-and-found system works remarkably well because of a combination of cultural honesty and organized procedures. Citizens who find items are legally required to turn them in to koban within 7 days, and finders may receive a reward (通常、落とし主から見つけた人に見返りが与えられることが一般的). If your wallet is returned with cash inside, it is customary — though not required — to offer the finder 10-20% of the cash as a thank-you gesture.
Train lost property offices at major stations like Yokohama and Shinjuku handle thousands of items daily. Staff can search their database if you describe the item and remember which train line and approximate time you were traveling. Foreign passports found on JR trains are forwarded to the Railway Police within 24 hours for embassy notification.
For items lost on Shinkansen bullet trains, contact the JR East Lost Property Center within 3 days — items are sent to Tokyo Station's Shinkansen lost property office. The system is efficient enough that many travelers report recovering lost items within 24-48 hours, particularly if they act quickly and check the right locations.
