Left Something on a Toei Bus - Lost and Found, Step by Step

Note down four things the moment you notice

What you should do after leaving something on a Toei Bus depends on how soon you notice. If you have only just stepped off, the quickest route is to contact the bus depot or branch office that is responsible for the bus you were on. If more time has passed, your entry point is either the chat service, which accepts inquiries around the clock, or the Toei Transportation Customer Center, which answers the telephone from 9:00 to 20:00 (as of September 2026). The item itself does not stay where you left it: as the days pass it moves from the depot to the Bureau's Lost and Found Center, and after that to the Metropolitan Police Department's lost property center.

Whichever desk you end up contacting, you will need to say when you rode, which route, and what you left behind. While your memory is still fresh, put the following four things into a note on your phone. A couple of minutes standing at the bus stop is enough.

• The route number - the number shown on the destination sign, such as 都 02 or 上 69. Once the route is known, it becomes clear which depot to ask.
• The date and time - which day it was, roughly what time you boarded, and roughly what time you got off. An approximation is fine.
• The stop where you got off - the name of the stop where you alighted. Adding the stop where you boarded makes it easier to pin down which run you were on.
• Your seat and the item itself - how far back you were sitting and on which side, plus the color, the size, the material and what was inside.

The last two matter more than people expect. The more ordinary the item, the more the outcome depends on how precisely you can describe it. Say only "a black bag" and the staff may be holding your bag without either of you being able to confirm that it is yours.

Where a forgotten item goes as the days pass

An item picked up on board is not left where it was found. It is first gathered in at the depot or branch office responsible for that bus, and from there it keeps moving: the Tokyo Metropolitan Bureau of Transportation states plainly that the place where a found item is kept changes according to how many days have passed. At the end of the chain the item is handed over to the Metropolitan Police Department's lost property center, where it is held for about three months.

The broad sequence looks like this.

What is worth noticing here is that counting the days yourself achieves very little. The Bureau explains that the storage periods shift with weekends and public holidays and should be treated as a guide only. In other words, something left on a Friday and something left on a Monday will move on at different points. Rather than working backwards from a number of days and giving up because the item "must be with the police by now", it is faster and far more reliable to ask and be told where it actually is.

The guide figures for how long items are kept are published as a table on the Bureau's page on lost items (as of September 2026).

Three ways to ask, and how to choose between them

Once you have those notes, the question is where to send them. As of September 2026 the Tokyo Metropolitan Bureau of Transportation offers three entry points for lost item inquiries, and the right one depends less on what you lost than on when you noticed and how much time you have.

Before you use any of them, one shortcut is worth trying. If you have only just stepped off, the Bureau asks you to contact the bus depot or branch office responsible for the bus you rode. While the vehicle is still out on the road, that is the shortest route to the people who can look for it once it comes back in. Depot and branch contact details change over time, so look them up on the Bureau's guidance page rather than trusting a number you wrote down on an earlier trip.

The chat service, which the Bureau introduced in June 2025, works like this. You register with an email address, and there is no app to install. The authentication notice contains a link that opens a web form, you enter the details of the item, and an operator searches the records and replies. Attaching an image is worth the extra few seconds, because AI reads the features of the photographed item automatically. Four languages are supported: Japanese, English, Chinese (simplified) and Korean.

One limit deserves care. If the first search draws a blank, the operator will look once more the following day, but only that once. Put the route number, the time and where you were sitting into your very first message rather than holding details back for a follow-up exchange that may not happen.

For the telephone route, the number for the Toei Transportation Customer Center is 03-3816-5700, and the Bureau's English-language page lists 03-3816-5711 for inquiries in English, Chinese, Korean, Spanish and Portuguese (both as of September 2026). Numbers and opening hours are exactly the sort of detail that gets revised, so confirm both on the Bureau's own page before you dial.

What to bring, and where to collect it

Once you know the item is being held, the next step is collecting it. What you need to bring is official identification that shows both your name and your address. The Bureau gives a driving license, a My Number Card and a health insurance eligibility certificate as examples. Describing the contents of a bag correctly is not enough on its own: if your identity cannot be confirmed, the item will not be handed over. If your ID was inside the wallet or case you left behind, dig out a different document from home before you set off.

Someone else can collect on your behalf, but the paperwork grows.

• A letter of authorisation - a document showing that you asked that person to collect the item for you.
• Official ID for the person who lost the item - that is, your own document, and here a copy is acceptable.
• Official ID for the person collecting - the representative's own document. A copy is not accepted for this one, so the original is needed.

Where you go depends on where the item is being kept. In some cases it is handed over at a station counter or at a bus depot or branch office, and in others you travel to the Bureau's Lost and Found Center. For counters, the guidance notes that staff may be unable to deal with lost property in the early morning or late at night, so if you were planning to drop in before the first bus or after the last one, check first.

The Lost and Found Center is in Kasuga. The nearest exits are A1 and A2 at Kasuga Station on the Toei Mita Line and the Toei Oedo Line, and by bus the stop is Kasuga-ekimae on the 都 02, 都 02 乙, 上 60 and 上 69 routes. It opens from 9:00 to 20:00 and does not close for holidays (as of September 2026). A quick look at how to ride a Toei bus is enough to get you there without hesitating on a route you have never used.

Sticking points and common misunderstandings

Even people who follow the steps in order run into the same few snags. Knowing them in advance saves a wasted journey or a mistaken identification.

• Do not head straight for the Lost and Found Center - your item may still be sitting at the depot. The Center is where things are handed over, not where the search begins. Ask first, establish where the item is, and travel afterwards.
• Umbrellas and keys cannot be described in words - the Bureau itself says that items with many lookalikes can be difficult to identify, gives umbrellas, keys, scarves, gloves and glasses as examples, and asks people to come and check in person at the place of storage. The Bureau asks for that in-person check because a description in words has its limits.
• Chasing a bus that is still running will not get it back - for buses in service, the Bureau states plainly that it cannot carry out searches for lost property or hand items over on board. Waiting at the next stop will not persuade anyone to check the seats mid-journey. Directing the request to the depot or the chat service is the correct order.
• Assume you will collect it on another day - because items are moved as they are stored, there is no guarantee of getting one back on the spot. For anything your daily life depends on, such as a commuter pass or a key, work out a stopgap for the waiting period at the same time as you file the inquiry.

If you would rather not handle the inquiry in Japanese, the Bureau's English-language guidance lists the desks that take inquiries in other languages. The Customer Center is described as handling conversations in English, Chinese, Korean, Spanish and Portuguese (as of September 2026).

Small habits that prevent it, and what to do next

Things get left behind in the short window between starting to gather your belongings and the doors opening. Slipping one extra step into that window cuts the losses considerably.

1. Look around your seat as soon as you press the button - the few dozen seconds between pressing the stop request button and the bus coming to a halt are the only unhurried moment you get for checking.
2. Run a hand over your lap and the floor before you stand - touch is more reliable than a glance. Paper bags and folding umbrellas resting on your knees are the first things to drop out of your field of view.
3. Count your belongings the moment you step off - decide before boarding that you have three items, say a bag, an umbrella and a shopping bag, and you can check them off on the sidewalk.

Anything tucked beside a seat or pushed behind a seat back will not announce itself as you stand up. Winter scarves and gloves, parasols and glasses tend to be set down without your body registering where. That list overlaps almost exactly with the examples the Bureau gives for items that can be difficult to identify. The very fact that so many look alike is what makes them hard to get back.

If you do leave something behind, there are only two things to remember. Straight after getting off, contact the depot responsible for the bus you rode. Once time has passed, use the chat service or the telephone. And before you make contact, line up the route number, the date and time, the stop where you got off and where you were sitting. With those two in hand, the operator or the depot can start searching straight away.
