Ooboke Koboke in Shikoku. I haven't been there, but my kids and wife have visited, and they say it's gorgeous and quiet.

Or anything on the west coast of Japan.

Of course, there's no work, no shopping, no entertainment...

If you're looking for a place to work (e.g. for a decent-sized company), but is also not too frenetic, I vote for either Sendai or Kobe.

Sendai is a little more "country" and Kobe is a little more sophisticated, but neither even come close to the busy-ness of Tokyo.

HTH.

Sore ja.
