Daigo-ji (醍醐寺 Daigo-ji) is a Shingon Buddhist temple in Fushimi-ku, Kyoto, Japan. Its main devotion (honzon) is Yakushi. Daigo, literally "ghee", is used figuratively to mean "crème de la crème" and is a metaphor of the most profound part of Buddhist thoughts. Daigo-ji was founded in the early Heian period. In 874, Rigen-daishi (Shōbō) founded the temple. After having fallen ill and abdicated in 930, Emperor Daigo entered Buddhist priesthood at this temple. As a monk, he took the Buddhist name Hō-kongō; and shortly thereafter, died at the age of 46. He was buried in the temple, which is why his posthumous name was Daigo.
