I don't think you'd be very successful trying to find a music/production school in Japan. Plenty of business schools though. Have you considered staying with an American university and then using a program such as ISEP to fulfill a year or so of your degree's studies overseas? That's what I'm doing. I do music/theatre/business, but most of my business schooling is going to be done overseas for the education, cultural experience, and possibility of international networking. You never know.

Also for the drunks thing, I heard a few exchange programs. I guess it depends on the people really, because I remember being told a story from an exchange student where they made some friends and had a bit of a party to start off the year but kind of got in trouble for being loud; bad way to start off representing America. ;P
