As for why people are attracted to Japan, Why not? You've never asked me why I speak English, Dogsbody
Many Japanese people ask me why I'm in the states and what the attraction is. I guess I can make just as much money in Japan, but it's just more... um.. interesting here?
Some people want to go far, as far as they can go, to experience different cultures. I explored out of my own culture and now I'm talking to you in a language that is not my own. I think it's fascinating.
