Any hot springs on your itinerary? If not, I would definitely head out to the Japan Alps, eg. the
Oku-Hida Onsen Villages are a good (if pricy) choice. If you want to see the evil twin of Himeji's White Egret Castle, then you could stop by
Okayama and see the pitch black Crow Castle.
Onomichi is also interesting in a quiet sort of way if you aren't tired of temple-tramping yet.
And then, of course, there's
Expo 2005 just outside Nagoya! Right now this would probably be my top pick, if you're going in a few weeks the weather should also be pretty optimal.
Has anyone been to Naruto? I've heard that there are gigantic whirlpools in the Naruto bay.

Is it even on the way back to Tokyo?
Been there and seen 'em (which requires some luck with tide timing). They're rather underwhelming and no, they're not on the way to Tokyo, they've between Shikoku and Awaji Island an hour or so south of Kobe.
