The whole nation was shocked by the hijacking of a bus in the middle of the "Golden Week" holiday season. And it was a 17-year-old boy who seized the bus and killed one passenger.

Many heinous crimes have been committed by teenagers recently: Another 17-year-old boy murdered an elderly woman in Toyokawa City, Aichi Prefecture, In Nagoya, a group of teenagers swindled 50 million yen out of their friend.

What prompted these youngsters to commit such serious crimes? When I saw the scene of the bus hijacking on television, I felt as though I was watching a movie.
