Historical persons — Japanese Buddhist monks, sculptors, scholars, and patrons whose biographies anchor the works under reading. Each page carries dates, school, Wikidata link, and the works to which the person is most often tied.
Late Heian–early Kamakura (1133–1212)
Hōnen (法然, 1133–1212), founder of the Jōdo-shū — the first independent Japanese Pure Land school. Tendai-trained at Mt. Hiei from 1147, he formulated senchaku nenbutsu: recitation of Amida's name alone, exclusive of other practice, sufficient for rebirth in the Pure Land in the age of mappō. His 1198 Senchakushū anchors Pure Land doctrine in Japan; Shinran was his disciple. Exiled in the 1207 Kennin persecution, pardoned 1211, died at Ōtani 1212.
Late Nara–early Heian (774–835)
Kūkai (空海, 774–835), posthumous Kōbō Daishi — founder of Japanese Shingon Esoteric Buddhism. Sent to Chang'an in 804, he received the abhiṣeka transmission from Huiguo in 805 and returned in 806 as the eighth patriarch of the Esoteric lineage. He established Mt. Kōya (816) and Tō-ji (823) as Shingon's institutional anchors. His doctrinal corpus (Sangō Shiiki, Hizōhōyaku, Jūjūshinron) and the Tō-ji Lecture Hall sculpture mandala define the foundations of Japanese Mikkyō.
Late Heian–mid Kamakura (1173–1263)
Shinran (親鸞, 1173–1263), founder of the Jōdo Shinshū — today the largest Buddhist denomination in Japan. Tendai monk at Mt. Hiei from age nine; left in 1201 for Hōnen, exiled with him in 1207. His Kyōgyōshinshō (1224) reads Amida's Original Vow as the source of faith itself, making faith — not the recited nenbutsu — the decisive moment. He married Eshinni openly while a monk; the line continues today through the Hongan-ji.
