Mount Rai has two sanctuaries, one at the middle of the mountain and one at its peak. The middle sanctuary was founded in honor of Emperor Suinin whom he is conventionally considered to have reigned from 29 BC to AD 70. Both sanctuaries have been governed by the temple until the Edo period. However, the priest's lodge in the middle sanctuary was abolished by the separation of Shinto from Buddhism, introduced after the Meiji Restoration. Cultural properties, such as Buddha statues including the main Buddha and the ancient documents, were moved to the main hall.
