If you don't like big crowded cities I'd recommend Hiroshima and Fukuoka. Lived in both and they are great!
If you want to do a bit more tourism, Hiroshima might be better. But if you want to go out and have great food, I'd recommend Fukuoka.
Why not do both though? You can get a Shinkansen for less than 100$ and it takes a bit more than one hour.
