This is one of three great view spots (Hanamizusaka, Nishiyukisaka). This pass was named from the Japanese myth, Yamatotakerunomikoto. This pass was used for long time to connect Kai (North Yamanashi) and Suruga (South Mt. Fuji) since Kamakura period.
There is stele with the poem of Osamu Dazai who is the greatest writer in Showa period.
"Fujiniha Tsukimiso ga yoku niau"
"Mt. Fuji become more beautiful, when you see it with evening primrose."
