Sengen Shrine is said to have been built approximately eight hundred years ago.
During the early years (1185-90) of the Kamakura period, Minamonoto no Yoritomo went to battle in Matsuzaki Takinokawa, Toshima.
His wife, Masako, was worried about her husband and 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.
Masako eventually climbed Mount Kamenokoyama where she had a beautiful view of Mt. Fuji. Fujiyoshida is where Sengen Shrine is located and is said to
enshrine Masako’s guardian deity. She visited Sengen Shrine to pray for eternal luck on the battlefield for her husband and then built the statue of the
Seikanzenon Bodhisattva. The statue was called Fuji Sengen Daibosatsu Bodhisattva by the villagers and was long respected and worshiped. This became
the origin of Tamagawa Sengen Shrine.
In May, 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. Once the statue was cleaned at the Tamagawa River, it was found to have a leg missing. The leg was repaired and the statue was enshrined by a Shinto ritual on June 1. Since then, the Tamagawa Sengen Shrine holds this annual ritual in June.
