Shōken 勝賢 (1138–1196) was a senior Japanese Shingon master of the late Heian and early Kamakura periods, of the Daigo-ji Sanbō-in 醍醐寺三寶院 transmission line. He was the son of Naidaijin Fujiwara no Michinori 藤原通憲 (Shinzei 信西, 1106–1160), the great scholar-courtier of the Go-Shirakawa era, and was tonsured into the Sanbō-in line under Genkai 元海 and Yōgon 永嚴. He received his own abhiṣeka at the age of 22 (ca. 1159, per his autobiographical KR6t0193 Jishōki) and rose to be Tōji chōja 東寺長者 and abbot of Daigo-ji 醍醐寺座主. He served as principal religious counselor of Cloistered Emperor Go-Shirakawa 後白河院 in the latter’s monastic-political maneuvers of the 1180s, and was one of the principal figures of late-Heian / early-Kamakura imperial Buddhism.
Shōken’s surviving works in the Kanripo corpus include KR6t0193 Jishōki (1 fasc., dated 1179) — a detailed liturgical-historical record of his own gushi kanjō performance — and the eighteen-fascicle KR6t0195 Mìchāo (祕鈔), the great ritual-encyclopedic compilation later edited by his disciple Shukaku Shinnō 守覺親王.
Surviving works in the Kanripo corpus: KR6t0193 Jishōki (1 fasc.); KR6t0195 Hishō (18 fasc., with Shukaku Shinnō as editor).
