If you like your schoolgirls, your manga/anime and your digital software then Japan is the ideal place for you. I see no reason why you should hold yourself back in any way in planning to live there.

Japan has impressed me very much especially with it's technology being years ahead of ours but I'm not too keen on the earthquakes, the language (I'd rather learn French) and the unhealthy obsessions (I wouldn't want my daughter being stared at). I'd prefer to live somewhere quieter and only visit wild places like Japan on holidays
