✿ Frequently asked questions ✿

If you know the facility, ask its staff first. For a street loss or an unknown location, report to a police box or station. You can also follow up with the facility.

Q Will my item always be returned? ＋

No. A report or inquiry does not guarantee recovery. Storage locations and periods differ, so ask promptly and confirm the official instructions.

Q What if I am leaving Japan soon? ＋

Tell the contact your departure date and a reachable email or phone number. Ask whether collection by an authorized person or shipping is possible; documents and fees may be required.

1Check your recent stops

Checking recent stops

Move to a safe place and check your bag and pockets. Think about the last place you used the item: a seat, shop, hotel, or ticket gate. Note the time and route.

It is understandable to feel worried. A short pause helps you give staff a clearer account.

Remember this!
  • Check recent stops, starting with the last place you used the item.
  • Do not enter tracks or restricted areas to retrieve it.

2Ask the right place

Asking station staff

If you know the place, contact its staff or official lost-property service. For trains and buses, identify the operator, route, direction, and approximate time.

Staff may handle many similar items. Knowing which service you used helps them direct your inquiry.

Remember this!
  • Contact the facility or transport operator you used.
  • Check the next contact if the item has moved to another office or police.

3Describe the item

Writing item details

Write the item type, color, brand, size, and distinctive marks. A photo, receipt, or serial number may help. Keep personal details for the official contact.

A short note or translation screen is fine. Distinctive details help avoid returning someone else’s item by mistake.

Remember this!
  • Use photos or notes to describe distinctive features.
  • Say you left something behind and show the relevant details.

4Report to the police

Reporting at a police box

For a loss on the street or an unknown location, visit a police box (koban) or police station to submit a lost-property report. Give the date, place, description, and a contact you can use.

You do not have to explain everything perfectly at once. Notes help the officer record the details accurately.

Remember this!
  • Report the loss to police even if the exact location is unclear.
  • Keep checking likely places without assuming a report guarantees recovery.

5Protect important items

Protecting phone and cards

For bank cards and phones, promptly contact the issuer or mobile operator about suspension. For a lost passport, contact your embassy or consulate and the police for guidance.

Protecting access first can reduce worry while you wait. Staff do not need your password to identify your property.

Remember this!
  • Take protective steps while contacting places about the loss.
  • Use official contacts and do not share PINs or passwords with callers.

6Confirm collection

Collecting a found backpack

When an item is found, confirm the location, opening hours, ID requirements, and any reference number before visiting. Ask about authorized collection or shipping if you cannot go.

Identity checks protect the owner. Preparing the requested documents helps staff return the item safely.

Remember this!
  • Check collection instructions and required documents in advance.
  • Confirm storage, shipping and proxy terms without assuming overseas delivery.

✿ Summary ✿

Check your recent stops, contact the facility or transport operator, and report to police if the place is unclear. Protect important items promptly. Clear details and reliable contact information help staff match a found item to you.
