Jobs That Will Get Me to Japan?

My older cousin is letting me use his account, but that isn't the point. My question is, what sorts of jobs can get me to live or constantly travel to japan. I've read other things and being an English teacher seems too over-used and a lot of people are doing it. I'm talking about good paying jobs. I don't have to live in the lap of luxury but I would like to live comfortably, preferably in japan. Since I'm a sophomore, I want to know what kind of job I should start preparing to get a degree for. Please help! A little more info is that I'm in a lot of advanced classes and I'm also in MJROTC and the school marching band. I get really high grades. That's really all I can think of. I also speak japanese at a semi-professional level.

Suggestion:

Japan is a very isolated nation they love for foreigners to come and visit but they don't actually want you to live there. It's hard for foreigners to get credit cards, rent out apartments (don't even think of trying to buy a house) any just plain get citizenship (they do not allow dual citizenship so you would have to give up your original citizenship). English teachers and tutors are always in demand over their and tons of spots are available but if you want to do something different do a search for Japanese-American companies mostly likely these are going to be firms that deal with technology like software, etc. If you can get in to a company like that you could get to travel back and forth.
