Here is a map of the path I walked (download KML):
Starting at Fujino station (藤野駅) in Uenohara, I took the bus to the Kamazawa Iriguchi bus stop (鎌沢入口バス停). I then I went up Mount Mikuni (三国山) and the nearby Mount Shoto (生藤山). There was a good view of Mount Fuji (although a bit hazy) from there. I then followed the ridge until Wada Pass (和田峠) and went up again to reach the summit of Mount Jinba. I then followed the first part of the trail to Mount Takao but actually went down to Lake Sagami starting from Myo Pass (明王峠).
