Holiday help!

[Geoffacake]

okay, I've got a holiday with my Farther coming up, we're heading out to tentacle land Japan and we're looking to stay at a different area other than Tokyo for a week of the trip before returning back to Tokyo, although we already have these places down: Kyoto, Osaka, Kobe.
We'll be staying at the undecided area for 2 days, hopefully looking to see some cool stuff.

I need another place, somewhere with fabulous attraction, yet staying near the central island of Honshu.
