The Busuno Tōge pass road was used long ago for the practice of Shugendo, the mountain religion combining elements of Buddhism, Shinto, folk religion and other faiths, and which here was focused on Mt. Hishigatake. It is also said that it was used as a military road during the Sengoku (Warring States) period in the 16th century. During World War II, yamigome—black-market rice—was carried over this pass.
