To report a lost item, say ［物］をなくしました, then give four facts: where you last had it, when you noticed it was missing, what it looks like, and any identifying details. If you lost it inside a station, shop, or other facility, start with that facility. If it was on the street or the place is unknown, ask the police about a lost-property report.

Four facts make the report useful
Leo checks his pocket after leaving a shop and cannot find his wallet.
Leo財布がありません。
My wallet is not here.
He checks several likely places without recording where or when he last saw the wallet.
LeoWhere did I last have it?
Maya organizes the four facts Leo should report: last place, time, color, and contents.
Maya最後の場所・時間・色・中身
Last place, time, color, contents
Leo gives the facts and understands which form to complete.
Leo黒い財布です。駅で落としたかもしれません。
It is a black wallet. I may have dropped it at the station.

Report what is missing
| Japanese | Romaji | Meaning | Use |
|---|---|---|---|
財布をなくしました | saifu o nakushimashita | I lost my wallet | State the missing item |
スマートフォンを落としました | sumātofon o otoshimashita | I dropped my smartphone | Use when dropping it is likely |
忘れ物をしました | wasuremono o shimashita | I left something behind | Use for an item left in a place |
落とし物の窓口はどこですか | otoshimono no madoguchi wa doko desu ka | Where is the lost-property counter? | Ask inside a facility |
遺失届を出したいです | ishitsu todoke o dashitai desu | I would like to file a lost-property report | Ask at a police station or police box |
Do not spend the opening explaining every event. Name the item first so staff can direct you to the relevant desk or search category.
Say where and when
| Japanese | Romaji | Meaning | Use |
|---|---|---|---|
駅で落としたかもしれません | eki de otoshita kamo shiremasen | I may have dropped it at the station | The place is possible, not certain |
電車の中で見ました | densha no naka de mimashita | I saw it on the train | Last confirmed place |
午後三時ごろです | gogo sanji goro desu | It was around 3 p.m. | Approximate time |
今日、気づきました | kyō, kizukimashita | I noticed today | Time discovered missing |
The National Police Agency advises giving where and when the item was lost because those facts are used to cross-reference found property. If you are unsure, distinguish “last seen” from “noticed missing” instead of inventing an exact loss time.
Describe identifying details
| Japanese | Romaji | Meaning | Use |
|---|---|---|---|
黒い革の財布です | kuroi kawa no saifu desu | It is a black leather wallet | Color, material, and item |
小さい傷があります | chiisai kizu ga arimasu | It has a small scratch | Distinctive feature |
中に名前のカードがあります | naka ni namae no kādo ga arimasu | There is a card with my name inside | Verifiable identifying detail |
写真を見せてもいいですか | shashin o misete mo ii desu ka | May I show you a photo? | Offer visual evidence |
Do not say a full PIN or expose more sensitive information than staff need. If a bank card, credit card, or phone is missing, contact the issuer or operator promptly about suspending access; a language lesson and lost-property report do not secure the account.
Understand the next step
| Japanese | Romaji | Meaning | Use |
|---|---|---|---|
こちらに書いてください | kochira ni kaite kudasai | Please write it here | Complete a form |
まだ届いていません | mada todoite imasen | It has not been turned in yet | No match at this time |
警察に遺失届を出してください | keisatsu ni ishitsu todoke o dashite kudasai | Please file a lost-property report with the police | Facility directs you onward |
連絡先を書いてください | renrakusaki o kaite kudasai | Please write your contact details | Provide a reachable contact |
A lost-property report records the claim and supports matching; it does not prove the loss or guarantee a search or recovery. Procedures and online availability differ by prefecture.
Start with the facility, then use the official lost-property route
Source check (August 11, 2026): use the National Police Agency lost-property guidance for the current reporting process. The NPA route guide also directs people who lost something in a particular facility to start with that facility. Ask qualified staff about an unresolved language or process-safety question.
Give a lost-item report staff can act on
- Name the item before giving the story.
- Separate the last-seen time from the time you noticed the loss.
- Give objective identifying details.
- Follow the facility or police process, and separately protect cards or devices.
Carry the report from a facility to the police desk
Start with the station, store, hotel, or other facility where the item may have been lost. If staff direct you to the police, reuse the same facts—item, place, time, and identifying details—without inventing certainty.
