PREPARE IDENTIFYING DETAILS
Give the restaurant enough to check
Restaurant name and area, visit date and approximate time, party size or table area, and a description with color, brand, size, and distinctive features.
JAPAN RESTAURANTS
The sooner you provide a restaurant with a precise description and visit time, the easier it is for staff to check. A phone inquiry can help when the restaurant does not answer in English, but the restaurant may need time to check or follow its own collection process, and identity verification is always done by the restaurant — never on a caller's word alone.

Start with the restaurant that most likely has the item, give a precise description and visit time, and follow the restaurant's own collection process. For a passport, wallet, or device, treat the restaurant inquiry as one step, not the only step: the police lost-and-found system and your embassy or consulate are the next two parallel calls.
PREPARE IDENTIFYING DETAILS
Restaurant name and area, visit date and approximate time, party size or table area, and a description with color, brand, size, and distinctive features.
ASK FOR A SPECIFIC CHECK
Ask whether staff can check now, or whether you should call back after a shift change, and confirm the collection process and any ID the restaurant requires.
IF THE RESTAURANT CANNOT FIND IT
File a Lost Property Report with the police and, for a passport, contact your embassy or consulate. A restaurant inquiry does not replace either step.
Use the restaurant's first answer to decide what to do next. If staff say the item is being held, follow the restaurant's collection process. If staff need time to check, plan a short callback window. If staff cannot find it, or the item is a passport, wallet, or device, do not stop at the restaurant — the police lost-and-found system and your embassy or consulate are the next two parallel calls.
| Restaurant answer | What to do next | Confirm before relying on it |
|---|---|---|
| Has the item | Ask collection hours, the name or counter to ask for, and any ID the restaurant requires | The exact collection window, who you collect from, and whether the restaurant accepts a letter of authorization for someone else to pick it up |
| Cannot find it | File a Lost Property Report with the police (koban or station) and, for a passport, contact your embassy or consulate | The police reference number or receipt, your embassy or consulate's current requirements, and a way to reach you while you are in Japan |
| Need time to check | Ask when to call back and whether staff have searched the dining area, counter, restroom, and staff-only storage | A specific callback time, the name of the staff member who will look, and whether the restaurant can take a written description by email or LINE in the meantime |
| Asks for ID to collect | Go in person with the same passport or ID used during the visit; do not rely on a caller to prove identity on your behalf | The exact document the restaurant wants to see, whether a copy is acceptable, and the collection deadline |
A restaurant's answer changes with the time of day. The first call may catch the floor staff who last saw the dining area; a call after a shift change may reach the manager or the person who holds the lost-property log. Send a short written message to the restaurant's official email or LINE account in parallel, so the inquiry is in writing even if the call is missed. Keep the description stable across all three contacts so staff can match it to the same item.
For a passport, wallet, or device, the restaurant is only the first of three parallel tracks. Under Japan's Lost Property Act, a manager of a facility such as a restaurant must hand found property to the police within 24 hours, or the finder's rights to a reward or ownership lapse. The police then hold the item for 3 months; if the owner is not found, ownership transfers to the prefecture and the item is sold or disposed of. For a passport specifically, your embassy or consulate sets the replacement rules and usually requires a police reference number, so confirm those requirements before you travel to the police station.
Send this through the restaurant's official contact form, email, or LINE account. Do not include payment-card details, passwords, or passport images. Replace the brackets, keep the description to one screen, and add or remove lines to match your item.
EMAIL / DM TEMPLATE
Subject: Lost item inquiry — [item] at your restaurant on [date]
Hello, I visited your restaurant on [date] at about [time] for a party of [number]. I believe I left a [item, e.g., black leather wallet / passport / phone in a clear case] at the restaurant. Details: • Restaurant and branch: [name, area, nearest station] • Visit date and approximate time: [date, time] • Party size and seat: [e.g., 2 people, counter seat by the window] • Description: [color, brand, size, distinctive features, contents if safe to share] • Where it may have been left: [table, counter, restroom, coat area] Could you let me know whether an item matching the description has been turned in, when it is best to call back, and the collection process if the item is being held? I can be reached at [phone or email]. Thank you.
Treat the restaurant's collection process as a small, in-person procedure rather than a quick pickup. Staff will want to match the item to its description, and most restaurants will not release a passport, wallet, or device to anyone other than the owner without a letter of authorization. Bring the same document you used during the visit, and allow time for staff to retrieve the item from storage.
A restaurant may not have found the item, may not have a formal lost-and-found log, or may already have handed it to the police. Under Japan's Lost Property Act, a manager of a facility such as a restaurant must hand found property to the police within 24 hours, after which the police hold the item for 3 months. After a few days with no answer from the restaurant, treat the police and, for a passport, your embassy or consulate as the next two parallel contacts. JNTO's visitor hotline (24/7, English, Chinese, Korean) can help you decide which Japanese office to call first.
For restaurants and similar venues, we can make a routine phone inquiry in Japanese to ask whether the item is being held and what the collection process is. We do not collect the item on your behalf, and identity verification is always done by the restaurant, in person, under its own rules. For a passport, wallet, or device, the police and your embassy or consulate are the next two parallel contacts.
If you'd rather try the call yourself first, these phrases can help.
