Every operator knows the message. It arrives about six hours after checkout, usually from an airport: “Hi, I think I left my charger / jacket / kid’s stuffed rabbit in the room. Is it there?” If your cleaner has already finished the turnover and the next guest has checked in, the honest answer is often “I’m not sure”, and that’s a bad answer to give someone who is about to board a 12-hour flight.

Lost and found isn’t glamorous, and it doesn’t appear in any revenue model. Still, how you handle it shows up in reviews, in your message load and sometimes in a legal grey zone you didn’t know you were standing in. Here’s the system we use at our properties, and why each piece is there.

TL;DR

  • In our properties, the items we see most often are small and predictable: chargers, cables, adapters, toiletries, clothing and children’s toys. Your cleaning checklist should include a deliberate “sweep” for them.
  • Log every item when it’s found, with a photo, the date, the room and the reservation. Without a log you can’t answer guests quickly or prove what happened.
  • Decide on an internal window for contacting the guest and on who pays for shipping before anything gets lost, and put both in your house rules.
  • Japan’s Lost Property Act (遺失物法) covers items others leave behind, not only valuables. If you can’t return an item to its owner promptly, don’t donate or dispose of it yourself; confirm the police submission procedure with your local police box (交番).
  • When you ship abroad, the guest pays actual postage and reasonable documented costs; any separate handling fee should be disclosed and agreed in advance. Carrier rules on batteries, liquids and food apply.

What Do Guests Actually Leave Behind?

In our properties, the things guests leave behind are mostly small, plugged-in or hidden. The items we see most often are phone chargers left in wall sockets, universal travel adapters, clothes hanging behind the bathroom door, toiletries in the shower, items in the bedside drawer and children’s toys under the bed.

That pattern is useful, because it tells your cleaners exactly where to look. We added a short “left items sweep” to the turnover checklist: every socket, every drawer, behind the bathroom door, under the beds, the fridge and the safe if there is one. It takes about a minute. Finding an item during cleaning is far better than hunting for it after the next guest has moved in.

How Should You Log Found Items?

You should log each item with a photo, the date found, the room and the reservation it belongs to, ideally before the cleaner leaves the property. A shared spreadsheet or a dedicated chat channel is enough. Fancy software isn’t the point; making it a habit is.

The log solves three problems:

  1. Speed. When the guest messages you, you can answer in minutes (“Yes, a black USB-C charger, photo attached”) instead of asking the cleaner and waiting.
  2. Matching. If two groups checked out the same week, the reservation link stops you sending the wrong person a stranger’s jacket.
  3. Protection. If a guest later claims they left a laptop and you never found one, a consistent record of what was found is your best evidence of good faith.

We also send the photo to the guest proactively when the item is obviously personal, such as a passport or a child’s toy. Many guests don’t realise they’ve forgotten something until they’re home, and a quick “we found this, would you like it back?” tends to turn into a very warm review.

How Long Should You Hold Items, and Who Pays Shipping?

Set a clear contact window and shipping policy in your house rules before you need them. Making it up case by case leads to inconsistent treatment and awkward conversations.

What works for us:

  • Perishables and opened toiletries: discarded at turnover and not logged. Nobody wants half a bottle of shampoo posted to Melbourne.
  • Ordinary items (clothing, chargers, toys): the fixed period in our rules is only an internal window for reaching the guest and arranging a return. If the owner cannot be reached promptly, treat the item as lost property and confirm the police submission procedure rather than donating or disposing of it yourself. Police guidance for facility occupants is to submit items within 7 days when the owner is unknown, so check with your local police how this applies to your property.
  • Shipping: the guest pays the actual postage and any reasonable, documented packing or transport costs. If you charge a separate handling fee, disclose it in advance and agree it through the platform’s permitted payment method. We ask for payment before shipping, through the OTA’s payment request feature.

Write the policy in plain language in your house manual so you can simply point to it. Guests rarely argue with a rule that was there before they arrived.

What About Passports, Wallets and Phones?

Valuables and identity documents need extra care, and in Japan the law is involved. Japan’s Lost Property Act (遺失物法) sets out obligations for people who find lost property, including people who manage a facility where items are left behind. Generally, that means promptly returning the item to its owner or submitting it to the police. Exactly how it applies to items left in a private rental room is something to confirm locally, so ask your nearest police box once and write down what they tell you.

Our practical approach:

  • Contact the guest immediately through the booking platform. Many guests with a forgotten passport are still in the city and can come back.
  • If they can’t be reached or have already left Japan, consult the police rather than holding the item indefinitely. For passports, the guest will usually also need to contact their embassy.
  • Never ship cash. Wallets and cards go through the guest’s own instructions or the police, not an envelope.
  • Phones and laptops: store them securely, don’t try to unlock them, and record who handled them.

The principle is simple. With anything valuable or identity-related, your goal is a clear, documented chain of custody, not a clever shortcut.

What Should You Know About Shipping Items Overseas?

Most returns to overseas guests go through Japan Post’s international services, and the main traps are packaging rules, not cost. Lithium batteries, aerosols, liquids, food and alcohol all come with restrictions that vary by service and destination, so check the carrier’s current rules before you promise a guest anything. For example, Japan Post does not accept standalone power banks or portable battery chargers for international mail. Devices with installed lithium batteries may be accepted only if Japan Post’s conditions and the destination country allow it.

Customs forms are another small friction point. Describe the item honestly as “returned personal effects, used” with a realistic value, and ask the guest to confirm their full address and phone number in writing (in the platform chat is fine). Then send them the tracking number once it ships. That one message removes most of the follow-up questions.

Where Does Automation Help?

The “I left something” message is one of the more predictable categories in a guesthouse inbox, and that makes it a good candidate for partial automation. In our own setup, the guest chatbot recognises the request, explains the policy (contact window, shipping costs, what we can’t ship) and collects the item description and address. A human then checks the log and confirms. The bot handles the back-and-forth, and a person makes the decision about someone’s belongings. That split works for us in a lot of places.

FAQ

Q: Can I charge guests for returning items they left behind?

You can ask the guest to cover actual postage and reasonable, documented packing or transport costs. Any separate handling fee should be disclosed in advance and agreed through the platform’s permitted payment method. Put the policy in your house rules and collect payment before shipping.

Q: What should I do if a guest leaves a passport?

Contact the guest right away through the booking platform. If you can’t reach them, or they have already left the country, consult your local police box rather than holding the passport yourself, and suggest the guest contact their embassy.

Q: How long do I have to keep items guests leave behind?

A hold period in your house rules should only be an internal window for contacting the guest. If the owner can’t be reached promptly, the item is treated as lost property: don’t donate or dispose of it yourself. Police guidance for facility occupants is to submit items within 7 days when the owner is unknown. Confirm the correct procedure for your property with the local police.
