I've heard that if you'll be graduating just before going to JET you need at least one of the references to be from a lecturer. Other than that I guess you just choose people who can attest to your professional attitude/interest in Japan/teaching ability etc. and who have some kind of authority - I vaguely remember reading something about having to have it printed on a letterhead from the business/education institution? I think even if you can use references from classmates or coworkers, their opinion will possibly carry less weight in terms of a professional or academic reference.

I plan to ask my kung fu teacher (for culture, teaching experience, international experience and because I think he'll let me write it for myself anyway >_>) and my Japanese teacher or boss, both of whom are very nice and may be inclined to write something nice about me.
