Saichō, also known as Dengyo Daishi (767-822 CE), was a monk and scholar who founded the Buddhist Tendai Sect in Japan. Based on the teachings of the Chinese Tiantai Sect, Saichō's simplified and inclusive version of Buddhism grew in popularity, and its headquarters, the Enryakuji temple complex on Mount Hiei, became one of the most important in Japan as well as a celebrated seat of learning.
