Lost Something in Japan? How Lost and Found Works (Wallets, Bags, Umbrellas)
Updated: 2026-09-16
Quick answer
Hi, I'm Miya, and I help newcomers settle into life in Japan. Leaving a wallet on a train or a bag on a bench is stressful anywhere, but Japan has a well-organised lost-and-found system, and a surprising number of items do find their way back to their owners. This guide covers wallets, bags, umbrellas and cards. If it was your phone that went missing, we have a separate guide for that.
The short version: ask right away wherever you think you left it — station staff, the shop, the bus or taxi operator. Then file a lost-property report at a koban or police station, even if you're not sure where the item went. Keep your report receipt number, check back or search online, and bring photo ID when you collect. If your residence card or bank cards were inside, there are a couple of extra steps, which I'll walk you through.
Retrace your steps and ask quickly
The sooner you ask, the easier an item is to trace. If you left something on a train, go to the station staff counter and tell them the line, the direction, the approximate time and, if you remember, roughly which car you were in. Station staff can often contact other stations along the line. The Japanese words that help are otoshimono (something dropped or lost) and wasuremono (something left behind).
For buses, contact the bus operator's office; the route number and time are the most useful details. For taxis, a receipt usually shows the company and car details, so it's worth keeping one. Shops, restaurants, cinemas and large buildings generally hold items at their own counter for a while before passing them to the police, so a quick call or visit there is worthwhile too.
Filing a lost-property report at a koban or police station
In Japan, you can file a lost-property report, called an ishitsu todoke, at any koban (the small neighbourhood police box) or police station. It doesn't have to be the one nearest to where you lost the item. The officer will ask when and where you think you lost it, what the item looks like, and what was inside, such as cash, cards or documents. The more specific you can be about colour, size, material and contents, the easier a match becomes.
When the report is accepted, you'll usually be given a receipt number. Write it down or take a photo of it, because you'll need it when you follow up or collect the item, and it's also useful if you need to replace documents. If your Japanese is limited, it's fine to show the details written down or use a translation app on your phone; officers are used to helping people from overseas.
Searching online and waiting for news
Found items handed to the police are generally registered in a system that lets them be matched against reports. Many prefectural police forces also publish lists of found items on their own websites, which you can search by date, place and type of item. Railway operators often have their own lost-property enquiry by phone or online, and items left on trains may be moved from the station to a central lost-property office and then, after a period, to the police.
Items are only held for a limited time, so it's best not to wait too long before checking. If there's a likely match, the police or the lost-and-found office will usually contact you using the details on your report. Umbrellas turn up all the time, so describing yours clearly — colour, handle, any marks — really does help it stand out.
Collecting your item: what to bring
When you go to collect, bring photo ID such as your residence card or passport, your report receipt number, and be ready to describe the item and its contents so staff can confirm it's yours. Some offices may also ask for a signature. If the item is being held at a police station or lost-property office in another area, ask on the phone about opening hours and whether there are other ways to receive it.
If someone else needs to collect it for you, check in advance what they'll need, as a letter of authorisation and their own ID are often required. When you get your wallet or bag back, go through the contents on the spot, and if any cards are missing, start the replacement steps below straight away.
If your residence card or bank cards were lost
A lost residence card needs its own steps. Generally, you first report the loss to the police and get the report receipt number, then apply for a replacement at your regional immigration bureau within 14 days of noticing the loss. You'll usually need your passport, a photo and proof of the police report. Requirements can change, so please confirm the current process with the Immigration Services Agency (出入国在留管理庁) before you go.
For bank cards and credit cards, call the card issuer or your bank as soon as you notice, so they can stop the card; their lost-card number is usually on their website or your statements, and saving it in your phone ahead of time is a good habit. If your My Number Card was in the wallet, it can be suspended through its dedicated helpline, and your municipal office can explain how to get it reissued.
A number the lost-and-found office can reach
Here's the part people often don't think about: when something turns up, lost-property offices, the police and your card issuer will usually try to reach you by phone. That's why the report asks for a contact number, and it really helps if it's a Japanese number you can actually answer, rather than a line from home you can't pick up here. Having a Japanese phone number with data also makes it easier to search found-item lists and call stations on the go. Setting one up is simple — you apply online with your residence card, verify with a quick eKYC, and eSIM-capable phones can often connect the same day in about fifteen minutes.
