Mountian biking near Fussa
 

I will be moving to Yokota AB soon and would like to meet up with any local mountain bikers if there are any around there. I have heard there are some trails but I will need a guide. Any help would be great.

This blog is written by bike shop owner located near Yokota AB.
the blog says, bikers in the base come his shop. and he is concerned with the setting up of the trail course. you should get some information.(but I'm not biker, Idon't know this shop. excuse me, if it's not useful.)
Enjoy your biker's life!
