Lost and Found in Japan: Getting Your Things Back

Lost and found in Japan runs on a national law, a network of police boxes, and separate systems at each railway, taxi company, and venue, and a large share of handed-in items do reach their owners again. In Tokyo, about 83% of mobile phones (119,516 of 144,064) and about two-thirds of wallets (226,993 of 337,601) processed by the police went back to their owners, figures calculated from the raw counts on the Tokyo Metropolitan Police Department's lost-property statistics page for 2025 (as of 2026-10; confirm current figures with the Tokyo Metropolitan Police Department).1 Getting your item back still depends on contacting the right holder quickly, because each operator and each prefecture keeps its own records.

Confirm current details with official sources

Fees, rules, and requirements can change. Confirm current details at the National Police Agency's "Information Site of lost belonging".

Overview​

Japan's lost-property framework is the Lost Property Act (遺失物法, Ishitsubutsu-hō, Act No. 73 of 2006).2 It requires a finder to return an item to its owner or submit it to the police promptly; a finder inside a facility such as a station or shop hands it to the business running that facility instead.3

The police post a public notice for items whose owner is unknown and maintain it for three months. If no owner is identified in that time, ownership passes to the finder.45

The system serves visitors as well as residents. Anyone can file a Lost Property Report at a police station or police box, and the National Police Agency gives specific instructions for people who are leaving Japan.678

How the holding chain works​

A lost item usually passes through up to three holders: the place where it was found, that operator's central office, and finally the police. Knowing which stage your item is likely at tells you whom to call first.

The diagram below shows the usual path. Railway, taxi, store, and airline holding periods of about one week come from Tokyo Metropolitan Police guidance (as of 2026-10; confirm current practice with the Tokyo Metropolitan Police Department), and the three-month police period comes from the Lost Property Act.12136

特例施設占有者tokurei shisetsu sen'yūshaSpecial facility occupier, a designated large operator allowed to store found items itself14

Vehicle or venue holds first​

The law sends facility finds to the facility, not the police, so the first holder is usually a station office, shop counter, or vehicle operator.3 Railway companies, taxi companies, stores, and airlines typically keep items for about one week while waiting for the owner to get in touch, according to Tokyo Metropolitan Police guidance (as of 2026-10).12151613

On Tokyo Metro, for example, an item stays at the station where it was found on the day it is lost (as of 2026-10).17 Reports from inside facilities may take 1–2 weeks to reach the police (as of 2026-10).18

Operator or facility center holds next​

An ordinary facility occupier must return the item or submit it to the police promptly, and loses its own reward and ownership rights if it does not submit within one week.1920 Designated large operators (特例施設占有者) may keep found items themselves instead, provided they notify the police within two weeks; high-value items designated by cabinet order are excluded from this exemption.1420

Each operator's practice differs, so treat the following as operator-specific examples, not a nationwide rule:

  • Tokyo Metro: from the day after the loss through day 4 at the Lost & Found Center at Iidabashi Station (Namboku Line side, outside the fare gates, 9:00–20:00 every day), then the TMPD Lost and Found Center from day 5 (as of 2026-10).17 Tokyo Metro's English page gives the Iidabashi period as three to four days (as of 2026-10).21
  • JR East: the holding period differs by station, after which items go to the designated police station; JR East searches for items lost within three months of the loss date (as of 2026-10).22
  • JR Central: items stay at the receiving station for a period, then transfer to the JR Central Lost & Found Center in Aichi Prefecture, which can take several days. Claims are accepted up to three months from handover, and the center does not offer in-person pickup (as of 2026-10).23

Police center holds last​

Police keep found property for three months from the day it is reported.68 Everyday items such as umbrellas and clothing may be sold or disposed of if the owner is not identified within two weeks.624

After three months the finder may take ownership but must collect within two months, or that right is lost.2510 Items carrying personal information, such as credit cards, ID cards, and mobile phones, cannot pass to the finder.2610

In Tokyo, the TMPD Lost and Found Center is at 1-9-11 Koraku, Bunkyo-ku, near Iidabashi Station (JR Sobu Line East Exit; Tokyo Metro Tozai Line exit A3; Yurakucho and Namboku Lines exit B1; Toei Oedo Line exit C2) (as of 2026-10).27 This center covers Tokyo only; other prefectures run their own.

The table summarizes the timeline. Rows marked "stable" come from the Lost Property Act; the others are Tokyo examples (as of 2026-10).

Where to report by loss location​

The first call goes to whoever runs the place where you lost the item. Filing a police report as well covers you if the item is later handed in elsewhere.

The routing in this table follows the Lost Property Act's facility-first rule, and the contact channels are dated in the last column (as of 2026-10; confirm current contact details with each operator or the local police).3

Trains and stations​

Each railway runs its own lost-property channel, and there is no single search covering all of them.2223281732 JR East, JR Central, JR West, Tokyo Metro, Toei, and each private railway must be contacted separately; contact numbers are in the operator table under "Railway operator inquiry channels" below.

Tokyo police advise filing a Lost Property Report at a police box or police station in addition to contacting the railway.12 On Tokyo Metro, the item is at the station office on the day of loss and at the Iidabashi Lost & Found Center from the next day (as of 2026-10).3317

JR Central lists the details it asks for: date of travel, approximate boarding and alighting times, the section traveled, train name or number, car number, seat number, and where exactly the item was; for phones the carrier and model, and for wallets or bags the contents (as of 2026-10).23 Other railways ask for similar details, so note them before you call.

Taxis​

In Tokyo, contact the taxi company directly if you know it, using the receipt or the dispatch app; if you do not, file a report at the nearest police station or police box (as of 2026-10).29

The Tokyo Taxi Center does not handle lost items itself; the taxi operator stores the item before it goes to the police, and handling may differ by operator (as of 2026-10).29 Its page lists contact numbers for 17 radio-dispatch groups and taxi associations, some with a dedicated lost-item line, for example Nihon Kotsu Musen 050-3173-9200 (weekdays 9:00–17:00), Tokyo Musen 03-5860-9517, and Kokusai Musen 03-5530-6054 (as of 2026-10).29 These lines cover Tokyo only.

Tokyo police guidance says taxi companies typically keep items for about one week (as of 2026-10).13

Streets, parks, and public spaces​

File a 遺失届 (ishitsu-todoke, "Lost Property Report") at a police station or police box, giving the date, time, place, and a description of the item.6 Items lost in transit may be reported to the police station nearest the final terminal, so a different station from the one where you filed may be the one that contacts you.18

Police do not search based on your report

Filing a report does not start a search. The police contact you only if a matching item is handed in, so keep calling the operator or venue directly.6

If you lost cards or a phone, contact the issuer or carrier immediately to suspend them.6

How you file depends on the prefecture. In Tokyo, the TMPD's English pages say forms are available at any police office, reports are accepted in person and not by email, and a Japanese phone number is required because the police do not, as policy, make international calls (as of 2026-10).347 TMPD's Japanese-language page also offers online filing through its Japanese-only online administrative service for losses that include less than ¥1,000,000 in cash (as of 2026-10).35

In the 44 prefectures on the National Police Agency's shared portal, which excludes Tokyo, Osaka, and Ehime, you can file a loss report online in Japanese, English, Chinese, or Korean (as of 2026-10-09).36

Shops, museums, and other venues​

Contact the facility first and file a police report if needed.8 Stores typically keep items for about one week before submitting them to the police, according to Tokyo police guidance (as of 2026-10).16 By law, ordinary facility occupiers must submit unreturned items to the police within one week to keep their own rights.1920

Airports run their own channels:

  • Narita: find chat (24-hour intake, replies 9:00–21:00) and phone 0476-34-8000 (24 hours). The channel does not cover the area after the security check for international flights and before customs (as of 2026-10).30
  • Haneda: find chat (9:00–21:00), and the Information Center at 03-5757-8111 (as of 2026-10).31

For items left on a plane, contact the airline and file a police report; according to Tokyo police guidance, airlines usually keep items for about a week (as of 2026-10).15

Searching online and by phone​

No single search covers every operator and every prefecture. You will usually need the operator's own channel plus the police system for the prefecture where the item was lost.3614

The National Police Agency's English "Information Site of lost belonging" explains the procedures and links to each prefecture's search page.1037 Its shared portal lets you search found items and file a loss report online in Japanese, English, Chinese, or Korean (as of 2026-10-09; confirm current coverage with the National Police Agency).36

The shared portal covers 44 prefectural police forces; Tokyo, Osaka, and Ehime are not on it and run their own systems (as of 2026-10-09).36 Items still held by an operator appear only to the extent that operator has reported them to the police, so contact the operator directly regardless.3614

Prefectural police databases​

Tokyo's online database can be searched by item type and date but is only available in Japanese (as of 2026-10).347 The TMPD Lost and Found Center's phone line is 0570-550-142 (8:30–17:15), and its counter is open 8:30–16:30 Monday to Friday, closed on national holidays and December 29 to January 3 (as of 2026-10).2734 The TMPD main switchboard is 03-3581-4321 (as of 2026-10).9

Osaka Prefectural Police run their own lost-property information system and publish an English "Lost Property" leaflet for tourists on their English page (as of 2026-10).38 Other prefectures follow the same national law but keep separate databases and contact points.37

Railway operator inquiry channels​

The table lists each operator's lost-item channels (as of 2026-10). Each row covers only the named operator.

Tokyo Metro's Japanese and English pages list different phone numbers and different online channels (as of 2026-10).3317 The Japanese lost-property page is the more specific of the two; if one number does not connect, try the other.

On JR West, items lost on certain Shinkansen lines or on other companies' trains must be reported to that company (as of 2026-10).28 JR Central ended its email Lost Item Inquiry Form at 17:00 on 2025-09-30 and moved to find chat from 08:00 on 2025-10-01.41 Toei introduced find chat, which uses AI image matching, on 2025-06-10.40

Tokyo Metro says calls from international numbers will not connect, and asks callers to give a phone number because staff may need to call back (as of 2026-10).33 Common look-alike items such as umbrellas, gloves, scarves, and hats cannot be handled by email or phone and must be checked in person (as of 2026-10).2133

Operator language lines first, hotel staff as backup​

Several operators provide their own language support: Tokyo Metro's English line uses a three-way interpreting service, and the JR East Infoline, JR West's hotline, and Toei's line offer foreign languages (as of 2026-10).33392832 Try these first.

Where a line is Japanese-only, you can ask hotel front-desk staff whether they can help place a call. Treat that as a courtesy to ask for, not a service to count on.

Tokyo police require a Japanese contact phone number on the report and ask people leaving Japan to give a contact in Japan (as of 2026-10).3442 A hotel can serve as that contact only if it agrees to.

Claiming your item​

When an item turns up, you collect it in person, send someone on your behalf, or arrange shipping. Each holder sets its own requirements.

What to bring​

In Tokyo, the TMPD asks for the following (as of 2026-10; confirm current requirements with the Tokyo Metropolitan Police Department).3443

SituationBringAs of
Claiming yourselfValid ID (passport, driver's license, or residence card); your Lost Property Report; the notification letter if you received one; your reference number2026-1034
Someone claims for youTheir valid ID; photocopies of their ID and your valid ID; your Lost Property Report; a Letter of Authorization; your reference number2026-103443

TMPD says a friend in Japan can collect with a letter of attorney "in any form" giving permission (as of 2026-10).43 It publishes English and Japanese PDF forms with samples, including the Lost Property Report, Acknowledgement of Receipt, Property Shipping Request, and Letter of Authorization (as of 2026-10).44

Nationally, the NPA advises contacting the police station during working hours before you go; a proxy needs a Power of Attorney and a copy of the proxy's ID.6

Operators set their own rules:

  • Tokyo Metro: the English page asks for ID such as a passport, and a letter of proxy if someone else collects; the Japanese page also lists a 印鑑 (inkan, "personal seal") for the owner and for a proxy (as of 2026-10).2117
  • JR West: claim at the station or lost and found center within the storage period, with government ID such as a passport; proxy pickup only in unavoidable circumstances (as of 2026-10).4546
  • JR East: may require verification such as testing a device, and travel costs to collect are yours (as of 2026-10).22

The NPA notes that a Lost Property Report "is not a document to prove that an item of property has been lost."8 For a lost passport, the police issue a separate certificate, covered in the passport section below.4748

The finder's reward​

When you get an item back, the Lost Property Act says you must pay the finder a 報労金 (hōrōkin, "finder's reward") of 5–20% of the item's value.2 The finder may waive it; otherwise, if the finder requests it, you pay the reward and storage costs, with the amount and method agreed directly between you.186

If the item passed through a facility, the reward is split rather than reduced. You pay the finder and the facility occupier half each, so 2.5–10% each and 5–20% in total.2

Costs of submitting, handing over, and storing the item are also borne by the owner.49 Reward and expense claims lapse one month after the item is returned to you.50

Government bodies and public corporations cannot claim a reward.2 A finder who does not submit a street find to the police within one week, or hand a facility find to the facility within 24 hours, loses the reward and ownership rights.2010

Shipping a recovered item after departure​

If your item surfaces after you leave, the police and most operators will ship only within Japan. The practical route is a person or address in Japan who can receive it.

The diagram shows the options, based on Tokyo police, NPA, JR West, and JR Central guidance (as of 2026-10; confirm current shipping options with the holder of your item).5185223

Police and operator domestic forwarding​

In Tokyo, the TMPD ships only to an address in Japan, at the owner's cost (as of 2026-10).51 It asks for a Property Shipping Request, a photocopy of the recipient's ID, a photocopy of your ID, a Lost Property Report if you have not filed one, a Letter of Authorization if someone else receives the item, and the notification letter if you received one (as of 2026-10).51

Nationally, the NPA asks for a Lost Property Shipping Request Form and a Receipt of Lost Property, and shipping costs are payable in Japanese yen only. If someone in Japan can receive the item or contact the police for you, give their details.86

JR West ships cash-on-delivery to addresses in Japan, including hotels and package-forwarding companies, as long as the forwarder accepts cash-on-delivery; JR West may decline (as of 2026-10).455246 JR Central ships only 着払い (chakubarai, "cash on delivery") from its Lost & Found Center, adds charges for items containing cash, and cannot ship explosives, combustibles, hazardous items, instruments, or large luggage (as of 2026-10).23

International shipping​

None of the police pages reviewed offers direct overseas shipping; Tokyo police state that items can be shipped to an address in Japan (as of 2026-10).51 Your contact in Japan, or a forwarding company, then sends the item abroad.

Phones and laptops face airmail battery rules

Japan Post treats lithium batteries as dangerous goods for airmail. Devices such as phones, laptops, cameras, and game consoles should have the battery removed unless it meets the conditions of Article 16 of the International Mailing Regulations, an exception that applies only to some countries and territories (as of 2026-10).53

Check the rule for your destination with Japan Post before your contact sends a device.53

Commercial recovery services​

JR Central's lost-and-found page points international shipping requests to eBackHome, a third-party service (as of 2026-10).23

That referral covers items held by JR Central only. The police and the other operators covered here ship within Japan, so check with whoever holds your item before paying a third party.51852

Name a contact in Japan before you leave​

The step that saves time is naming a contact in Japan when you file. Tokyo police ask people leaving Japan to give contact details for someone in Japan who can be reached if the item is found (as of 2026-10).42

The NPA asks people leaving Japan to give a valid email address and phone number on the report, plus details of anyone in Japan who can receive the item.8 In Tokyo, that person can later collect the item with a Letter of Authorization, which can be in any form (as of 2026-10).4344

Lost passport: a separate emergency​

A lost passport is a lost-property case and a travel-document problem at the same time. The police side follows one national law, but the embassy side depends on your nationality.

The sequence below shows the order of steps.485455

File a police report first​

Report the loss at the nearest police box to get a certificate of the lost-property report and a report number, which the embassy needs.48 Iwate Prefecture's guidance calls this document 遺失届出証明書 (ishitsu todokede shōmeisho, "Lost Item Report certificate"); the exact name can vary by source.48

In Tokyo, that certificate comes from the police station handling your Lost Property Report, not the TMPD Lost and Found Center (as of 2026-10; confirm current procedures with the Tokyo Metropolitan Police Department).47 Some embassies, such as Australia's, ask you to report a lost or stolen passport to local police before applying (as of 2026-10).54

Contact your embassy or consulate​

Documents, fees, and processing times are set by your own government. Two examples show how much they vary, and both apply only to their own citizens:

  • Australia: an application form, two passport photos, any ID you have, General Declaration Form B11, a police report if available, and card payment. Emergency passports can take up to two business days, and you book an appointment at the Tokyo or Osaka office (as of 2026-10).54
  • United Kingdom: an emergency travel document costs £125 (non-refundable) and is usually ready two working days after applying, longer in some cases; an appointment may be required (as of 2026-10).56

Check your own embassy's page for its requirements and timing.

Your landing stamp can be transferred if wanted

Japan's Immigration Services Agency says a holder of a new passport may, if desired, request transfer of the valid landing-permission stamp from the lost passport by submitting a 証印転記願出書 (shōin tenki negaidesho, "request for transfer of stamps") to a regional immigration office, bringing the loss certificate if available.55 Ask the immigration office whether you need it for your departure.

JNTO Visitor Hotline as a bridge​

The Japan National Tourism Organization (JNTO) runs the Japan Visitor Hotline at 050-3816-2787 (+81-50-3816-2787 from overseas), 24 hours a day, 365 days a year, in English, Chinese, and Korean (as of 2026-10).57 It supports visitors in emergencies such as accidents or illness, during natural disasters, and with general tourist information.57

The same JNTO page lists Lost & Found at 0570-550-142, the Tokyo police center's number, and police at 110 (as of 2026-10).57

Good to know​

Car and seat numbers narrow train searches​

Railways ask for the train name or number, car number, seat number, and the item's exact location, and giving these narrows the search (as of 2026-10; confirm current requirements with the railway).23 Writing them down as soon as you notice the loss is a practical habit, and a timestamped phone photo of the platform sign can help you reconstruct the details later.

Shinkansen and through-running trains may belong to a different company from the station you used. JR West directs items lost on certain Shinkansen lines or on other companies' trains to that company (as of 2026-10).28 Check which operator ran the train before you call.

A written note bridges the language gap at the kōban​

The report needs the date, time, place, and a description of the item.6 In Tokyo, the TMPD publishes an English Lost Property Report form with a sample that you can fill in beforehand and bring in person (as of 2026-10).447 Elsewhere, a short written note with those details and a photo of the item on your phone is a practical way to get past a language gap.

Tokyo police also require a Japanese contact phone number on the report and, as policy, do not make international calls (as of 2026-10).34 Arrange a contact in Japan before you file.

Same-day retrace loop for same-day losses​

On Tokyo Metro, an item is at the station office on the same day, at Iidabashi from the next day through day 4, then with the TMPD (as of 2026-10).17 Because the police do not search based on your report, contacting the first holder directly matters most in the first hours and days.6

Plan around closures. TMPD counters close on national holidays and from December 29 to January 3, and the JR East Infoline closes over the year-end and New Year period (as of 2026-10).3439

Keep digital copies before you need them​

If cards or a phone are lost, contact the issuer or carrier immediately to suspend them.6 In Tokyo, a proxy collecting your item needs a photocopy of your ID, so an image of your passport data page lets a friend in Japan act for you (as of 2026-10).3443 Noting your phone's carrier and model and your wallet's contents also speeds matching (as of 2026-10).23

Tokyo Metro's Japanese page lists a personal seal (inkan) among claim requirements, while its English page lists ID only (as of 2026-10).2117 If you do not have a seal, confirm with the counter before you go.
