You'd be a good one. You know your stuff, and you know how to make it interesting.

...Though really, especially since you're in the art end of things, who says you can't have both? Do the shop crap and have craft classes on the side. It'd be easier to really interact with the people who wanted to learn it, and you could help without being held to the education-industrial complex's stupid standards. I know American schools are terrible about the arts, and Japan's even more test-happy, so God only knows how they handle that.
