Japanese Police and Lost Property Phrases
Japanese phrases for reporting lost property at a koban, describing items, filing a report, handling stolen cards, collecting belongings and calling police.
At a Japanese police box, say 財布をなくしました。遺失届を出したいです (saifu o nakushimashita. Ishitsutodoke o dashitai desu): “I lost my wallet and want to file a Lost Property Report.”
If the item disappeared inside a train, shop, airport or hotel, contact that facility first. Freeze cards and phone service separately; a police report does not do that for you.
Key takeaways
交番(koban) is a neighborhood police box.遺失届is a Lost Property Report.- Contact the managed facility first when the location is known.
- Give last time/place and unique identifying features.
- Suspend bank cards, credit cards and phone service immediately.
- Use 110 for an active crime or accident, not routine lost property.
- Keep the report/reference information.
- Confirm identity, pickup and shipping requirements before leaving Japan.
