Approximately 4.5 million lost items were reported in Tokyo last year—the highest number ever recorded. Among them was cash totaling around 4.5 billion yen.
According to the Tokyo Metropolitan Police Department, the dramatic rise in lost property cases reflects changing conditions in the city, including an increase in foreign tourists.
A Record Number of Lost Items in Tokyo
The Tokyo Metropolitan Police Department announced that the number of 落とし物 (otoshimono, lost items) reported 都内 (tonai, within Tokyo) over the past year reached about 4.5 million cases.
In news language, this was described as 過去最多となる (kako saita to naru) — “becoming the highest ever.”
The total 件数 (kensuu, number of cases) set a new record. Among these lost items, the amount of 現金 (genkin, cash) alone 上った (nobotta, amounted to) approximately 4.5 billion yen.
To put that into perspective, that’s billions of yen in cash turning up at police stations across Tokyo.
Why So Many Lost Items?
The police believe that one major 背景 (haikei, background factor) behind this increase is the growing number of foreign visitors to Japan.
In news reports, this is expressed using the phrase:
- 外国人旅行者の増加などが背景にあるとみている。 Gaikokujin ryokōsha no zōka nado ga haikei ni aru to mite iru. “They believe that factors such as the increase in foreign tourists are behind it.”
The expression 〜とみている (to mite iru) is commonly used in journalism to show what authorities or experts believe based on current information.
Cultural Context: Lost and Found in Japan
Japan is internationally known for its efficient lost-and-found system. When people find wallets, phones, or even cash, they often bring them to a nearby police box, called 交番 (kōban, neighborhood police box).
Although the article does not give further details, the sheer scale—millions of items and billions of yen—highlights how structured and organized Japan’s reporting system is. Every item is counted and recorded, contributing to detailed annual statistics like this one.
For Japanese learners, this kind of news story is especially useful because it contains formal expressions and vocabulary that frequently appear in reports.
