With an inner-city population fast approaching 14 million people, millions of items go missing here each year. But a staggering number of them find their way home. In 2018, over 545,000 ID cards were returned to their owners by Tokyo Metropolitan Police – 73% of the total number of lost IDs. Likewise, 130,000 mobile phones (83%) and 240,000 wallets (65%) found their way back. Often these items were returned the same day
In a study comparing dropped phones and wallets in New York and Tokyo, 88% of phones “lost” by the researchers were handed into the police by Tokyo residents, compared to 6% of the ones “lost” in New York. Likewise, 80% of Tokyo wallets were handed in compared to 10% in New York. The abundance of police stations must make it easier, but is there something else going on.
