Lost and Found in Japan: A Complete Guide for Tourists

If you lose something while traveling, understanding lost and found in Japan can help you act quickly.

Losing your wallet, smartphone, passport, or bag can be stressful, especially if you are not sure who to contact.

Fortunately, Japan has a well-organized lost and found system. Train stations, hotels, restaurants, stores, airports, and the police all handle lost property, and many items are kept for a certain period after they are found.

The most important thing is to act quickly and contact the right place. If you know where you may have lost your item, contact that facility first. If you lost it on the street or are not sure where it disappeared, you can report it to the police.

In this guide, we explain how lost and found in Japan works, what to do depending on where you lost your belongings, and how to handle important items such as passports, wallets, smartphones, and IC cards.

Even if your item is not found immediately, do not give up. Lost property may take some time to be registered or transferred to another lost and found office.

What to Do First If You Lose Something in Japan

As soon as you notice that something is missing, try to remember the last place you used or saw it.

Think about where you were, what time you were there, and whether you may have left the item on a train, at a restaurant, in a hotel, in a taxi, or somewhere else.

If possible, write down the approximate time and location, as well as details about the missing item such as its color, size, brand, and anything inside it. A photo of the item can also be very helpful.

If you know where you probably lost it, contact that facility first. Train stations, hotels, restaurants, stores, and airports often keep lost property temporarily.

If you lost the item on the street or are not sure where it disappeared, visit a nearby police station or police box, known as a koban, and report the loss.

Acting quickly and providing clear details can make it much easier to identify your belongings if they are found.

Where Did You Lose It?

The best place to contact depends on where you think you lost your belongings.

If you clearly remember leaving something on a train, at a station, in a hotel, restaurant, store, airport, or taxi, contact that company or facility first.

Many businesses and transportation companies in Japan keep lost items for a certain period before transferring them to the police.

If you are not sure where you lost the item, or if you dropped it on the street or in another public area, visit a nearby police station or koban and file a lost property report.

Knowing where you last had the item will help you decide who to contact first and may increase your chances of getting it back.

On a Train or at a Station

If you lose something on a train or at a station, speak to station staff as soon as possible.

Tell them which train or line you used, the approximate time, where you boarded and got off, and where you think the item may have been left.

If you know the train number, car number, or seat number, provide that information as well.

Lost items may not appear in the railway company’s system immediately, so do not assume that your item is gone if staff cannot find it during your first inquiry.

It can be helpful to check again later, especially if the train continued to another station or another railway company’s line.

If you are not familiar with Japan’s railway system, see our beginner’s guide to using trains in Japan.

If you lost something on a JR East train or at a JR East station, check the official JR East lost and found service.

At a Hotel, Restaurant, or Store

If you think you left something at a hotel, restaurant, department store, convenience store, attraction, or shopping mall, contact that business first.

Tell the staff when you visited and describe the item as clearly as possible, including its color, size, brand, and any distinctive features.

Hotels can be especially helpful because they already have your reservation information and may be able to contact you if something is found in your room or elsewhere in the building.

If the business no longer has the item, ask whether it has already been transferred to a nearby police station.

At an Airport or on a Plane

If you lose something inside an airport terminal, contact the airport’s lost and found service or information counter.

If you leave something inside an aircraft, contact the airline instead.

Large airports have different areas managed by airlines, shops, security services, train operators, and airport staff, so try to remember exactly where you last had the item.

Providing your flight number, terminal, gate, shop name, or approximate location can make it easier for staff to find the correct lost and found service.

In a Taxi

If you leave something in a taxi, check your receipt first.

Taxi receipts usually contain information that can help identify the taxi company or vehicle.

If you booked the taxi through an app, check your trip history and use the information there to contact the taxi company.

Prepare your pickup location, destination, approximate travel time, and a detailed description of the missing item.

If you cannot identify the taxi company, you can also report the lost item to the police.

On the Street or You Are Not Sure Where

If you dropped something on a street, sidewalk, park, or another public area, visit a nearby police station or police box, known as a koban.

You should also contact the police if you are not sure where you lost the item.

Tell the police when and where you last remember having it and describe the item in as much detail as possible.

A lost property report allows the police to compare your information with items that are handed in later.

How to Report Lost Property to the Police in Japan

If you lose something on the street or are not sure where it disappeared, you can report it at a police station or police box, known as a koban.

When you file a lost property report, the police record information about the missing item so they can compare it with property that is handed in later.

Try to report the loss as soon as possible and provide as much detail as you can.

Keep in mind that filing a lost property report does not mean the police will actively search for your belongings. Instead, your report helps them identify your item if someone later brings it to the police.

For more information, see the National Police Agency’s official guide to lost property in Japan.

What Information Should You Prepare?

Before reporting a lost item, prepare as much information as possible.

Useful details include the date and approximate time you lost it, the location where you last saw it, the type of item, its color, size, shape, brand, and any distinctive features.

If you lost a wallet or bag, describe what was inside it. For electronic devices, serial numbers or other identification information may also help.

A photo of the item can be especially useful if it is difficult to describe.

Can Tourists Use a Koban?

Yes. Foreign travelers can visit a koban to report lost property and ask the police for help.

A koban is a small neighborhood police box commonly found near train stations, shopping areas, and residential neighborhoods throughout Japan.

Not every police officer will speak fluent English, but you can show a photo of the missing item, a map, train information, receipts, or translated text on your smartphone.

You do not need to speak perfect Japanese to report a lost item.

What If You Lost Something on a Train in Japan?

Trains are a common place for travelers to leave bags, umbrellas, phones, and other belongings.

If you notice something is missing, speak to station staff as soon as possible.

Japan has many different railway companies. The company you need to contact depends on the train you used.

Your item may also move to another station or a lost and found center. For this reason, it may not be found immediately.

Ask Station Staff as Soon as Possible

If you have just left the train, talk to station staff immediately.

Tell them which railway line you used. Also explain where you boarded and where you got off.

Give them the approximate time of your trip. If possible, tell them the train’s destination as well.

The car number and seat number can also help. You should also explain where you may have left the item.

For example, tell staff if it was on a seat, under a seat, or on an overhead rack.

The more details you provide, the easier it may be to identify the correct train.

Items May Move to a Lost and Found Center

Lost items do not always stay at the station where they are found.

A railway company may first keep the item at a station. It may later move to a central lost and found office.

After another period of time, some items may be transferred to the police.

This means the storage location can change over time.

If your item is not found during the first inquiry, ask staff when you should check again. You should also ask where the item may be transferred.

Tokyo Metro also explains how lost items move from stations to its Lost & Found Center and later to the police.

Through-Service Trains Can Make It More Complicated

Some trains in Japan continue onto another railway company’s tracks.

This is called through-service. Passengers can stay on the same train even when the railway operator changes.

If you lose something on one of these trains, your item may be found on another company’s network.

You may need to contact more than one railway company.

If you are not sure which company to contact, show station staff your route. They may be able to tell you which railway operators were involved.

What to Do If You Lose Important Items

Some lost items require faster action than others.

Passports, wallets, credit cards, and smartphones contain important personal information. They may also be difficult to replace during your trip.

Do not only wait for the item to appear at a lost and found office. You may also need to contact your embassy, card issuer, mobile carrier, or railway company.

The steps you should take depend on what you lost.

Lost Passport

If you lose your passport, contact your country’s embassy or consulate in Japan as soon as possible.

Ask what you need to get a replacement passport or emergency travel document.

You should also report the loss to the Japanese police.

However, the documents required can vary by country. Ask your embassy first whether you need a police certificate.

Keep any report number or documents you receive from the police. You may need them during the replacement process.

For more information about lost passports and other lost property in Tokyo, check the Tokyo Metropolitan Police Department’s English guide.

Lost Wallet or Credit Card

If you lose your wallet, act quickly.

Contact your credit card company or bank first. Ask them to suspend any missing cards.

Next, contact the place where you may have left the wallet.

If you do not know where you lost it, report the loss to the police.

Tell the police what was inside the wallet. This may include cash, cards, identification, or other items.

Do not wait for the wallet to be found before blocking your cards.

For more information about cash, credit cards, and other payment methods, see our complete guide to money in Japan.

Lost Smartphone

If you lose your smartphone, use its location service if available.

You should also contact your mobile carrier. Ask them how to protect your account and prevent unauthorized use.

If you left the phone on a train, at a hotel, or in another facility, contact that place immediately.

If you do not know where you lost it, report the loss to the police.

It is also useful to keep your phone’s model, color, and serial number somewhere else. These details can help identify your device.

Lost IC Card

If you lose an IC card, speak to station staff as soon as possible.

Reissue rules depend on the type of card you have.

For example, a personalized PASMO can be reissued if it is lost. A blank PASMO cannot be reissued.

Visitor cards may have different rules. A lost Welcome Suica cannot be reissued.

Tell station staff which IC card you lost. They can explain the options available for your card.

Check the official PASMO website for the latest rules on lost cards and reissuing personalized PASMO cards.

How to Pick Up Your Lost Item

If your item is found, check where it is being stored before you go to collect it.

It may be kept at a station, lost and found office, police station, or police property center.

Ask what you need to bring with you.

You may also receive a reference number or report number. Keep this information until you get your item back.

Do not go to the location without checking first. The item may have already been moved to another office.

Bring Identification

You will usually need identification when you collect a lost item.

For international travelers, a passport is often the easiest form of identification to use.

You may also need a lost property report number or other reference information.

The exact requirements can vary by police department or company.

Check what documents you need before you travel to the pickup location.

Can Someone Else Pick It Up?

In some cases, another person may be able to collect your item for you.

However, extra documents may be required.

You may need to prepare a letter of authorization. Copies of identification may also be necessary.

The rules depend on the organization holding the item.

Ask about the requirements before sending a friend, hotel staff member, or another person to collect it.

What If You Have Already Left Japan?

Your item may be found after you have already returned home.

If this happens, contact the police, railway company, hotel, or other organization that is holding it.

Ask whether they can send the item to you or whether someone in Japan can collect it on your behalf.

International shipping is not always available.

In some cases, the item may only be sent to an address in Japan.

A friend, hotel, or other trusted person in Japan may be able to help.

If you leave Japan before your item is found, give the organization a reliable email address.

You should also ask how they will contact you if the item is found later.

The Tokyo Metropolitan Police Department also provides guidance for travelers whose lost property is found after they have already left Japan.
