Sanmyoji Temple is said to have been established at the beginning of the 8th century. Its principal image worshipped at the main hall is Benzaiten (the goddess Saraswati). During the period of the Genpei Wars (1180-1185), a priest at this temple, Mochizuki Chugen, fought with Minamoto no Noriyori’s forces and was defeated. When Noriyori became a lord of Mikawa province later, he ordered one of his retainers, Kawai Goro, to burn the temple down, from which the temple was destroyed. The temple was restored by a Zen monk Mumon, a son of Emperor Godaigo, in the 14th century. The 15 m three-story pagoda built in 1531 is well-known for its beautiful shape. It is an eclectic-styled building; the 1st and 2nd floors are built in Japanese style, while the 3rd floor in Chinese style. As architectural styles in the Muromachi period (1336-1573) varied form region to region, the pagoda is a precious building structure to know the architecture in the late Muromachi period. The pagoda and Guden Hall (the main hall) are designated as National Important Cultural Properties.
