Japanese total immersion school in rural areas?

I'm looking for a total immersion school for learning Japanese which is NOT located in a big city. Ideally, a rural or suburb area. Also, I'd prefer it in the Kyushu region if possible. But I don't really want to study in Fukuoka city. Does anybody know of any schools for learning Japanese located in the country side? I have a reasonably good grip on Japanese, so language barriers is not an issue.
