The little boy pictured above got on the JR (Japan Railway) train when I was headed to work in the early afternoon one day. He bounced around the car a bit and I realized that he was all alone and that this was not a rare situation. Little kids in Tokyo ride the train alone as well as walk around various neighborhoods. Kids in Tokyo can do this because there is little fear of child abduction in Japan.
I will miss living in a culture in which small children can walk around without an adult because it is safe enough for them to do so.
