Amusingly, I remember watching a Derren Brown special where he said he did basically the same thing when he was counting cards to beat the dealers in card games. Though to be fair, Derren Brown has a tendency of making up convenient excuses for whatever it is he's really doing.

This is basically where I am. I read a post on reddit about it a few months ago, signed up, got everything in order. No idea if i'll ever be called upon, but I think it'd be cool if I were.

It's not a requirement but it obviously helps. These positions only require a degree from a 4 year university. They're not the primary instructor for any of their classes; it's much closer to a student teaching position. You coordinate with the main teacher to offer lessons or supplement what they're teaching. In theory, the Japanese person teaching English should know enough to help you out at school and your contracting organization can usually arrange to help with certain things you need (getting stuff set up with the local government).
