Shane is fine, if you're willing to teach kids then there are a lot of options for you with decent pay.

@MMM, for full time positions you're entirely right. I was thinking of sub/alt positions, short term fill-ins etc. Also it's possible that what I thought was a public school was in fact private, it's hard to tell the difference for me sometimes.

@Sangetsu, you're entirely right, get any job to get the visa (and experience and connections if you're lucky) and then start your own gig. That's what I did. Anything else generally tops you out at around 3000yen an hour and you wont see more than that for the rest of your career.
