I left my umbrella / wallet on the train. Is it really worth checking?

Yes. Railway operators take in millions of lost items a year and return a large share. Ask station staff or contact the line's lost-property service with the date, time, and which train you were on.

Do I have to speak Japanese to use a koban?

It helps, but officers are used to assisting visitors and residents, and koban in major tourist areas often have multilingual support. A translation app and a calm description go a long way.

A caller said my bank card or phone was suspended. What should I do?

Treat it as a scam. Do not press buttons, share codes, or transfer money. Hang up and, if unsure, contact your bank or provider using the number on your card or their official site. For consumer trouble, dial 188.

How long are lost items kept?

Usually a few days at the station or venue, then they move to the central police lost-and-found, which holds them for a limited period. Check sooner rather than later, and the official site lists current details.

Staying safe in Tokyo — and the magic of lost and found

Tokyo is famously safe, and lost wallets and phones really do come back. Here is how to use the koban, where to report a lost item, and the scams worth knowing about.

Tokyo can feel overwhelming at first — the crowds, the language, the sense that you would never find a dropped wallet again. Here is the reassuring part: Tokyo is one of the safest big cities in the world, and its lost-and-found culture is genuinely remarkable. People hand in wallets, phones, and umbrellas every single day, and a huge share find their way back to their owners. You still want to be street-smart, but you can relax more than you might expect.

The koban: your neighbourhood help point

All over Tokyo you will see small police boxes called koban (交番), usually near stations and busy corners and often marked with a red lamp. Staffed by local officers, they are far more than crime desks: they give directions, help when you are lost or in trouble, and take reports for lost and found items. If something feels wrong, or you simply cannot find your way, walking into the nearest koban is a perfectly normal thing to do. For a real emergency — a crime in progress, an accident, or someone hurt — call 110 for police or 119 for fire and ambulance.

Lost something? Here is where to look

Start nearest the loss, then work outward — items are usually held locally for a few days, then passed up to the central Metropolitan Police lost-and-found centre.
Nearest koban or police station — you can file a Lost Property Report at any police box or station; the form is available there.
The station, shop, restaurant, or venue where you lost it — railway stations and most businesses keep their own lost-and-found for a short time.
For trains: contact the railway operator's lost-property service — each line (JR, Tokyo Metro, Toei, private lines) has its own; ask staff or check the operator's official site.
The Tokyo Metropolitan Police (Keishicho) lost-and-found centre, where unclaimed items across the city eventually gather; there is also an online Lost Property Search.
Tip: note the date, place, train line or car number, and a clear description — it speeds everything up.

When you file a lost-property report, the police will usually need a Japanese phone number to reach you, and reports are made in person — not by email. If your item turns up, that is how they will contact you.

If you lose your residence card or passport

Treat these very differently from an umbrella. First, report the loss to the police (your nearest koban or station) and get the report — it is the proof of loss you will be asked for later. Then contact the official office that handles your case: for a residence card, the Immigration Services Agency of Japan; for a passport, your country's embassy or consulate. There are deadlines and required steps, and the exact procedure depends on your situation, so go straight to the official office rather than relying on second-hand instructions. This guide points you to the right door; the office itself will tell you what to do.

Scams worth knowing about

Nightlife touts and overcharging — in areas like Kabukicho, ignore people on the street pulling you into a bar or club; surprise bills and padded charges are the classic trap. Choose your own venue.
"Your card / phone / account is suspended" calls and SMS — a recorded voice or message says your service or bank card is blocked and presses you to act fast or share details. Hang up; banks and telecoms do not work this way.
Police or official impersonation — callers claiming to be police, immigration, or a delivery firm, often demanding payment or personal data. Real authorities will not ask for money or codes by phone.
Fake-charity collectors and high-pressure street sign-ups — be wary of anyone rushing you to pay or sign on the spot.
Investment and romance scams — "guaranteed" returns, crypto tips from new online friends, or a love interest who eventually needs money. If it sounds too good, it is.
Golden rule: never pay or hand over codes under pressure, and never share one-time passwords.

If you think you have been scammed or pressured into a bad contract, you can dial 188 — Japan's consumer hotline — to be connected to a nearby consumer affairs centre. For a crime or immediate danger, call 110. Save 110 (police) and 119 (fire and ambulance) now; interpreter support is available, so just say "English, please."
