On Kyūshū I have visited Fukuoka, Nagasaki, Beppu, Imari, Karatsu and some other small towns.
Where else on Kyushu have you been. I have been to Kumumoto, nagasaki, unzen, Beppu and fukuoka.
Sadly, no I did not. I did visit Mt Aso though. Here's a nice pic of the volcano.
In the thread about japan you mentioned the nature. Did you get to climb mount fuji?
