If you're interested in Japan, check out Tohoku University. They're a technical school which does English courses in Japan. Being Japan, it's also pretty easy to get scholarships (I most everything paid for when I was accepted, including 2 round trips from US to Japan per semester, food, housing, etc.). Finally, since they're an English speaking school, they do a lot of work with study abroad students.
The main downside to any study abroad program is transferring credits. Perhaps it is different at some schools, but at a fairly high level research university, it's almost impossible to transfer credits for anything outside of the core. The content has to be too similar. On the other hand, my school would let me transfer the courses as generic technical electives, so I'd recommend that to you.
