In Japan, even if you lost your wallet, camera, or iPhone, there would be a very good chance that they will be found.
I think many Japanese people are willing to deliver such lost properties.
When I was young, I lost my wallet.
I felt sorrow, and cried, but immediately got a phone call from a police box.
“Did you lost your wallet?”
I was so happy, and at that moment, I vowed that I deliver lost properties when I find them.
