I leave for Japan on Sunday for 2 weeks, Sorry Big Rig but i don't think that i'll make to Hokkaido, My girlfriend is Japanese and this is a meet the parents sort of trip

Anybody know where the good rock climbing area's are? I think the parents live near tokyo and then I think we will be in Nagano and then Kobe. She planned the trip and the names all sound similar so i get them wrong all the time. Oh ya I need one of those Alt/clino thingies that sit on the dash. Can you get them there?
Cheers
