Tamagawa Sengen shrine is said to have been built eight hundred years ago. When Minamoto no Yoritomo went to battle, his wife, Masako, worried about him, went looking for him, but was forced to abandon her journey due to a wounded foot. She decided to get treatment close to Tamagawa river and visited Sengen Shrine to pray for eternal luck on the battlefield for her husband. She then built the statue of a bodhisattva called Fuji Sengen Daibosatsu Bodhisattva by the villagers and was long respected and worshiped. This became the origin of Tamagawa Sengen Shrine. Four hundred years later, in 1652, at the time of construction of the pass to Sengen Shrine, the Chinese copper statue of Daibosatsu Bodhisattva was excavated under the 9th station of Mt. Fuji. It was cleaned at the Tamagawa River and enshrined. Since then, the Tamagawa Sengen Shrine holds an annual ritual to celebrate it.
