So I am racing Ironman Japan 70.3 (http://ironman703.jp/e/) in June, and I'll have a few days to kill after the race.

I'm not too keen to spend a ton of time in a train or bus, so is there anything relatively near Nagoya or Tokoname that would give me a taste of authentic Japanese culture?

I'm thinking a day trip with an overnight stay somewhere relatively nearby so I don't spend the day parked inside public transportation...

Ideas?
