Where on Kyushu should we go? We've scheduled 4 days for there.

Beppu sounds tacky and seedy and isn't really enticing. Miyazaki sounds like it'd be pretty sweet, but not sure how long we'd need there. 2 days maybe? 1?

Kagoshima sounded kinda interesting, too. Might only take 1 day, though?

Also, anyone who's been: is Fuji-Q Highland theme park worth visiting? And is Nagoya do-able in 1 day?
