I released the video Japan Granite vol.3.
In this movie I mainly focused on Toyota where the big bouldering area of Japan.
This granite boulders are relatively coarse but many cool rocks are scattered all around the place.
In particular the problem 太刀（Tachi）is the best one in this area.
There are sharp edges in the center of big steep wall.
You have to link micro crimps and then go big move to jag.
If you come Japan you should try it.
