Tokyocooney's Japan forum

Hello fellow travelers -

I've been to Japan twice and visited various places (Tokyo, Kyoto, Hiroshima, Miyajima, Osaka, Kobe, Shirakawa, Nagoya, etc), so when I am now going back for the third time, I'd really like to get to know Kyushu. I'll fly to Fukuoka and have almost 11 days to explore around. I have planned the following things so far:

Day 1 - Fukuoka
Day 2 - Nagasaki
Day 3 - Some smaller places around Fukuoka like Iizuka
Day 4 - Kumamoto & Aso
Day 5-6 - Beppu and Usuki
Day 7 - Sumo and shopping
Day 8 - Karatsu
Day 9-11 - OPEN

Any good suggestions for open days? Or would you replace something on my list? I've read conflicting info about visiting the southern part of Kyushu in November - some suggest that it'd still be nice, others suggest not to go at this time of the year. I'd appreciate any help very much!

Happy travels!
