Genkaku 賢覺 (also read Kenkaku; conventionally 1080–1156) was a Japanese Shingon master of Daigo-ji 醍醐寺 in the late Heian period, holding the rank of Hōgen 法眼 (“Dharma-eye”). He was a senior disciple of the Daigo Sanbō-in transmission line and active across the same generation as Yōgon 永嚴 (1075–1151) and Kanjo 寛助 (1057–1125). His surviving scholarly work KR6t0187 Zhuǎn fēimìng yè chāo — a doctrinal-ritual treatise on the Vajrāyus (Vajra-Longevity) practice and its capacity to “transform non-life-span karma” — places him in the Daigo-ji enmei-hō (longevity-rite) tradition, which became one of the principal services performed for the imperial court during the cloistered-emperor era.
