Personally I think their culture is much more so bound by honor than where I live. It would be nice to live somewhere where you don't have people rolling down their windows and randomly yelling "what's up, b***h*" every 30 min. (and I'm a guy, a very manly ginger guy).
I'm a major manga guy (going to SCAD university soon so that I can study sequential art and hopefully get a manga published) and so that alone would be a reason for me to love to live in Japan, but I also appreciate the fact that they, in general (not absolutely), have a more solid code of ethic than compared to here in the U.S.
Oh, and it's popular to eat healthy and make good grades, so that would be a plus!!! ^_^
