If I could change something about Japan...

Recently, I've been bothered by young people using cell phones on the train. It seems that they don't think of the people around them. This is very bad manners. If I could change something in Japan, I would want to change this situation.

For example, I think that whoever uses a cell phone on the train should be fined heavily. A law about cell phone manners like this should be made.
