Although Soken is said to be the first year of Datong (806), the current main hall (Yakushido), which was designated as a national treasure, was rebuilt in the second year of Shōjō (1258). The characteristics of the Kamakura-era esoteric architecture are expressed in the eaves that are deeply out. A 22m high triple tower, also a national treasure, stands in a cedar grove next to the main hall. The four statues made in the late Heian period, the main statue of Yakushi Nyorai, the statue of King Fushisan, the statue of the King of Fushan, the statue of the General of Shenzhen, and the statue of the King of Fudō are designated as important cultural treasures of the country, and are overwhelmed by their power.
