Lost passport in Japan: what to do first (2026)

Losing your passport in Japan feels catastrophic, but the process for replacing it is well trodden. The Japanese side of the problem — police reports and lost-and-found desks — is the same for every nationality. Only the embassy step differs.

Quick answer

Step	Where	What you get
1. Retrace	Call your hotel, train line, taxi company, airport desk	Sometimes the passport, same day
2. Police report	Koban (police box) or police station	遺失届 (lost-property report) + receipt number
3. Embassy	Your country’s embassy or consulate	Emergency travel document or replacement passport
4. Keep searching	Police lost-and-found systems	Passports are held about 3 months

Do steps 2 and 3 in parallel with step 4. Never wait for the passport to “turn up” before starting the embassy process.

Step 1: call the last places it could be

Passports usually go missing in a small number of places: the hotel room, a train, a taxi, a restaurant, or the airport. One phone call to the right desk beats hours of anxious searching:

• Hotel — front desk, housekeeping finds passports constantly.
• Trains — each operator has its own lost-and-found channel. JR East’s lost-item line is 050-2016-1601 (8:00–20:00), with an English/Chinese/Korean line at 050-2016-1603 (10:00–18:00). Most operators now push a 24-hour “find chat” web form first, which is the easiest option if you don’t speak Japanese.
• Taxi — call the company on your receipt or in your ride app. With the pickup point, drop-off point, and time, dispatchers can usually identify the exact car.
• Airport — Haneda runs a multilingual lost-and-found chat (9:00–21:00) at tokyo-haneda.com/lost; Narita’s airport police station (0476-32-0110) answers 24 hours.

These calls are in Japanese at most desks. If that’s the blocker, Native Call translates your side of the call into Japanese live — you speak English, the desk hears Japanese — or a human caller can do the calls for you.

Step 2: file a police lost-property report (遺失届)

This is the step travelers skip, and it matters twice over:

1. Your embassy will very likely ask for it. Most emergency-travel-document applications ask for evidence you reported the loss to police — a report number at minimum, sometimes a formal certificate.
2. It’s how the passport finds you. Anything handed in to Japanese police is matched against filed loss reports.

How it works:

• Go to any koban (police box — the small street-corner posts) or a police station (警察署). Koban are everywhere and handle this daily.
• Describe what you lost, where, and when. If you don’t know where, report the last time and place you’re sure you had it.
• Write down the receipt number (受理番号, juri bangō). This is the key to everything that follows.
• One caveat: a koban gives you a report number, but if your embassy asks for a formal loss report certificate (遺失届出証明書), that document is issued at a police station, not a koban. Check what your embassy requires before queueing twice.

Step 3: contact your embassy or consulate

This is the one step that depends on your nationality, so this guide won’t invent specifics — fees, documents, and processing times change and are published by each embassy. The universal shape:

• In a hurry to fly? Ask about an emergency travel document — most countries issue a limited-validity document in days rather than weeks. Note that emergency documents often carry routing restrictions (some are valid only for specific itineraries), so tell the embassy your exact flight plan, including any connections.
• Staying longer? A full replacement passport is the cleaner option but typically takes weeks.
• What almost every embassy asks for: the police report, passport photos, proof of identity (a photo of your old passport’s data page helps enormously — take one now if you still have your passport), and your travel itinerary.
• US citizens: the US Embassy in Tokyo and consulates handle emergency passports; check travel.state.gov for current requirements and appointments.
• UK citizens: apply for an emergency travel document via gov.uk.
• Australian citizens: contact the Australian Embassy in Tokyo; see smartraveller.gov.au.
• Taiwanese nationals: the process runs through TECO offices — see the Chinese-language version of this guide for the full 入國證明書 flow.

Call before you go. Many consular sections require appointments, keep short counter hours, and close on both local and home-country holidays.

Step 4: keep searching — passports do come back

Japan’s lost-and-found system is unusually effective, and passports are exactly the kind of item that gets handed in.

• Tokyo: search the Metropolitan Police lost-property database online, or contact the Lost and Found Center in Iidabashi (0570-550-142, weekdays 8:30–17:15).
• Osaka: there is no central lost-property hotline; file and search online via the Osaka Police portal, or ask the accounting section (会計課) of the local police station.
• Items handed in to police are generally held for about three months.

If the passport turns up after you’ve been issued a replacement, it’s usually invalidated — hand it to your embassy rather than traveling on it, and withdraw the police report.

Timing advice if your flight is soon

• Same-week flight: file the police report today, and call the embassy today — emergency travel documents typically need one or more business days plus an appointment slot.
• Flight within 24–48 hours: call the embassy’s emergency line and ask directly whether it’s feasible; simultaneously check what a one- or two-day flight change costs. A rebooking fee is almost always cheaper than a missed flight plus airport denial.
• Don’t gamble on the airport fixing it. Airlines cannot board you internationally without a valid travel document, no matter how good your story is.

FAQ

Do I really need the police report?

Yes. Most embassies ask for evidence of the police report before issuing an emergency travel document, and the report is also what matches your passport back to you if someone hands it in.

Can I file the police report in English?

At koban in tourist-heavy areas, often yes, at least partially. Elsewhere expect Japanese only. Keep your description simple, use the script above, or use a live phone translator for the conversation.

How long do Japanese police keep a found passport?

Items handed in to police are generally kept for about three months, matched against loss reports during that time.

Someone found my passport and it’s at a police station. What do I bring?

Bring the receipt number from your loss report and photo ID. If you’ve already been issued a replacement passport, tell your embassy — the old one is typically cancelled and shouldn’t be used for travel.
