Hiei, Mount ［比叡山］ ( Hiei-zan): A mountain located to the northeast of Kyoto, Japan, on which Enryaku-ji, the head temple of the Tendai school, is situated. Dengyō, the founder of the Tendai school, went to live on Mount Hiei in 785, and in 788 he built a small temple there called Hieisan-ji. Hieisan-ji was renamed Enryaku-ji by Emperor Saga in 823, the year after Dengyō’s death. Its first chief priest was Gishin, Dengyō’s successor. A number of important figures in Japanese Buddhism, including Hōnen, Eisai, Dōgen, and Nichiren, the founders of newer Japanese Buddhist schools, studied at this temple.
