Lost Something on a Train in Japan? What to Do, Step by Step
Short answer: act fast and go to the staff window at the nearest station, ideally the same day. Tell them which line, which direction, roughly what time, which car if you remember, and what the item looks like. In Japan a surprising amount of lost property is handed in and comes back. After a few days, items move from the railway company to the police lost and found, so the sooner you ask, the easier it is.
I work for a Japanese railway company, and lost-property questions come up all the time. Here's what actually helps.
Right away: ask at a station
If you notice while you're still at a station, or just after the train leaves, go straight to the staffed window by the ticket gates. Staff can contact other stations on the line, and sometimes the train itself. Have this ready, or show it on your phone:
- Line and direction (for example, "Yamanote Line, toward Shinagawa")
- Where you got on and off, and roughly what time
- Which car and where you put it: the rack above the seat, under the seat, by the door. Many platforms show car numbers on the floor or signs, and photos you took on the train can help.
- What it looks like: color, brand, size, and anything distinctive inside
A tip from the railway side: if you know the train's departure time and which car you were in, that helps more than anything else. Screenshot your route from your navigation app so you can show it.
Who to contact, by operator
Tokyo's trains are run by different companies (see how Tokyo's train network works), and each has its own lost and found. Contact the one whose train you left it on.
| Operator | How to ask | Notes |
|---|---|---|
| JR East | Phone 050-2016-1601 (8:00–20:00), or the online "find chat" (accepts messages 24 hours, replies 9:00–21:00) | JR East says the phone line is often busy and suggests the chat instead. |
| Tokyo Metro | Lost and Found Inquiry Form online, or phone 0570-033-777 (9:00–17:00) | Lost and Found Center at Iidabashi Station (Namboku Line, outside the gates), open 9:00–20:00 daily. |
| Toei Subway (and Toei buses) | Phone 03-3816-5711 (9:00–20:00, every day), or the online form/chat | Or ask at any Toei subway station. |
Contact details are from each operator's official page at the time of writing (October 2026). For other lines (Keikyu, Odakyu, Kansai railways and so on), ask at any station of that company.
How long items stay with the railway
Railway companies only keep lost items for a few days before handing them to the police. Tokyo Metro, for example, explains the timeline like this:
| When | Where the item is (Tokyo Metro) |
|---|---|
| Same day | Ask at the nearest station office |
| Next day to 4 days later | Lost and Found Center at Iidabashi Station |
| After 5 days | Sent to the Tokyo Metropolitan Police Department Lost and Found Center |
Perishable items are only kept for a day. JR East says each station keeps items for a different length of time before passing them on to the police, and that it searches for items lost within the past three months.
One more thing JR East points out: newly handed-in items take time to be registered in the system. If the first answer is "nothing found," ask again later.
If it has gone to the police
In Tokyo, items end up at the Metropolitan Police Department Lost and Found Center (phone 0570-550-142, weekdays 8:30–16:30, closed on national holidays and over the New Year break).
- Report it: file a Lost Property Report in person at a police station or police box (koban). You can fill in the form in advance, but you have to hand it in in person.
- Search: the police have an online lost-property search, but it's only in Japanese. Hotel staff are often happy to help.
- Phone number: the police contact you by phone and generally don't make international calls, so give a Japanese number if you can (your hotel's, for example).
- To collect it: bring valid ID (your passport), the item's reference number, and the notification letter if you received one.
If you've already left Japan
According to the Metropolitan Police, a found item can be shipped to an address in Japan after they check the paperwork. You pay the shipping. You'll need to post copies of the documents, including a shipping request and copies of ID. Someone you trust in Japan (a friend, or sometimes your hotel) can also collect it for you with a Letter of Authorization and a copy of your ID.
A few habits that prevent most losses
- Avoid the overhead rack for small things. Phones, wallets and passports left on the rack are the classic case. Keep them on you.
- Look back at your seat before the doors close. It takes two seconds.
- Keep a note of your train. A screenshot of your route with times makes any search much faster.
- Lost your IC card? Ask at a station office of the company that issued it. A mobile IC card on your phone avoids the problem of losing a plastic card (see our IC card guide).
