Cities and towns to work from in Japan - revisit

We had a discussion about a year ago about Japan, outside of Tokyo and Kyoto, but not too many ideas came up. I see that there are no less than 249 coworking places listed on Coworker now:

Has anyone had experience working in Japan, but outside of the big cities? How did you find accommodation? What did you like about the location? How long did you stay?

Cheers
