I really like Fukuoka (went 5 days and going back for 7 more), but it is a city (with great food

). Relaxed, different than Tokyo/Osaka but still a city.
Ramen heaven, but still a city.
If you like porcelain, you can do an easy excursion to Saga.
Imari (boring), Arita (a little boring), Okawachiyama (amazing).
When in November are you going ? Okawachiyama had last year the
autumn sale on 1/11-5/11. If you are in that period, the prices are very very good.
If you like the idea, I can help more because English info for this village is scarce.
Also, look up for: Dazaifu (Kyushu national museum - very good).
ps.
they uploaded info on japan guide. Damn...hurry up before the groups swarm in and ruin it

.
