Lost items now easier to recover with AI
Keio and Yurikamome report higher success in reuniting owners with lost belongings.

AI is supporting lost-and-found services across Japan, helping reunite thousands with misplaced possessions. Tokyo-based Find Inc has developed a platform now used by around 30 organisations at 2,300 sites, including train stations, airports and police departments.
The system analyses photos and descriptions of lost items and compares them with user-submitted information through apps like Line. Keio Corp and Yurikamome Inc report significant improvements in return rates since adopting the AI-powered tool.
Users can search for items in Japanese, English, Chinese and Korean, with the AI suggesting possible matches even from vague descriptions. The platform has handled over 1.5 million lost items, returning nearly half a million to their owners.
Previously reliant on spreadsheets and manual searches, many operators now benefit from faster identification and fewer inquiries. Tokyo and Oita police departments, along with commercial hubs like Hakata Station, have embraced the technology.
As adoption spreads, Find Inc aims to simplify the process of recovering lost items for even more people.
