天台宗
Japanese Tendai was founded by Saichō in the early Heian period, with Enryakuji on Mount Hiei as its head temple. Drawing on Zhiyi’s Chinese Tiantai teaching and the Lotus Sutra, it developed esoteric, meditative, precept and nembutsu (recitation of the Buddha’s name) practices. Its history includes ways of training monks, conferring precepts and organizing temple networks.
Zhiyi’s Chinese teaching and Saichō’s Japanese institution have connected histories.
Recognition of annual ordinands in 806 preceded independent ordination approval in 822.
The wider Tendai tradition includes distinct historical networks and later organizations.
Tendai honours the Chinese Sui-period teacher Zhiyi as its ancestral master and Saichō as its Japanese founder. Saichō established Ichijō Shikan-in on Mount Hiei in 788; it later became Enryakuji. A Chinese teaching tradition thus became connected with a particular Japanese history of institutions and temples.
In Tendai’s own account, the Lotus Sutra provides a framework for understanding the Buddha’s teachings. The One Vehicle is explained as the teaching that all people can attain Buddhahood. Studying scriptures and their relationships constitutes kyōmon, the aspect concerned with understanding doctrine.
Kanmon puts understood teaching into practice through shikan: calming mental distraction and attending to an object, together with observing it through wisdom. The two aspects work together. Tendai also includes esoteric rites, precepts and nembutsu, recitation of the Buddha’s name. Kaihōgyō visits sacred places in the mountains.

Saichō studied Tiantai teachings in China and received Zen and esoteric transmissions before returning in 805. In 806, permission was granted for two officially recognized ordinands each year: one for shikan training and one for esoteric study. Tendai treats this recognition as its formal establishment.

Saichō also sought permission for Mount Hiei to confer Mahayana bodhisattva precepts independently. The sect records approval seven days after his death in 822. Annual ordinands in 806 and independent precept ordination in 822 were separate institutional developments.
Ennin and Enchin studied in China, while Annen helped systematize Tendai esotericism, later called Taimitsu in distinction from Shingon’s Tōmitsu. Ryōgen developed temples and scholarship; Genshin’s Ōjōyōshū contributed to Tendai Pure Land thought. The range of practices accumulated through different historical developments.
Tendai interacted with regional sacred mountains and Hie Sannō worship. In its lineages, Enchin’s followers later formed Jimon at Onjōji, distinct from Ennin’s Sanmon line. Hōnen, Shinran and Nichiren studied on Hiei before establishing different traditions; Shinsei formed another Tendai lineage emphasizing precepts and Pure Land belief.

Oda Nobunaga’s attack devastated Mount Hiei in 1571. Support from Toyotomi and Tokugawa patrons helped reconstruction. Tenkai was important in this revival and developed religious centres at Nikkō and Edo. Kan’eiji, known as the “eastern Hiei,” became a base for Tendai in the Kantō region.
Government policies separating kami worship from Buddhism disrupted earlier religious combinations. Shiga Prefectural Archives present a report submitted in 1873 describing burned images, scriptures and ritual objects at Hiyoshi Shrine. It is a specific record of damage to the religious landscape around Hiei.

In 1872, state administration grouped Tendai and other Buddhist organizations into a seven-sect system, each with a superintendent; separate branch superintendents were permitted in 1874. Jimon’s chronology records the union of Sanmon, Jimon and Seimon in 1941, followed by the re-establishment of Tendai Jimon in 1946. Historical Tendai lineages can therefore belong to distinct organizations.
The sect’s “Light Up a Corner” (Ichigū o Terasu) movement, begun in 1969, developed study, welfare, fundraising and relief activities. The Hiei religious summit followed in 1987. A Hawaii mission opened in 1973, using services and lay organizations, and later pursued interreligious exchange and English-language teaching and ritual publications.
Kyōmon concerns understanding teaching; kanmon puts it into practice, including calming distraction and observing through wisdom in shikan.
The first permitted two annual ordinands. The second permitted independent conferral of Mahayana bodhisattva precepts on Mount Hiei.
Saichō and later teachers developed different bodies of study and practice over time, including Taimitsu and Genshin’s Pure Land thought.
No. Hōnen, Shinran and Nichiren studied there before developing separate traditions.
