If anyone is interested in Rock climbing in Japan.
There is a place called Ogawayama and the locals say its the best in Japan.
"Yosemite of Japan"
Here is a good link - http://www.ogawayama.com/
I went out the the area in the rainy season which was not the best idea but still was really worth it.
We trained to Matsumoto from Osaka. (not sure if this is the best place to get a car) Then drove to Ogawayama which takes about 2 hours.
