When I lived in Japan from 1984 – 1989, I never once locked my house (blue roof in the center) on the beach in Hayama, about 50 miles south of Tokyo on Sagami Bay. Sometimes I was gone, at sea, for two and three months at a time. Never locked my car, and I probably could have just left the keys inside.
I used to say that you could leave a pile of cash in the middle of a busy train station, come back and hour later, and retrieve it.
You know why it is, don’t you? They think too much of themselves to take what they haven’t earned.
