Oh, and OP: Think about what you want to do with your life, beyond living in Japan for a few years. Maybe keep in mind the fact that it helps greatly to have a degree if you want to live in Japan for more than a few months. Study in a field that you actually want to work in - doesn't have to be related to Japanese or TEFL at all, unless you do want to work in that area. Try for a study abroad program while doing your degree if you're in a position to. Graduate, get a job teaching over there.

Simple. It uh, might just take you a few years.
