Eshū 惠什 (also read Ejū, fl. early-to-mid 12th c.) was a Japanese Shingon monk active at the Shōjōbō 勝定房 of Anyō Valley 安養谷 in the early 1130s. His precise lifedates and primary monastic affiliation are not securely known, but the date-stamp of his sole surviving work — Hōen 1 (1135), 12th month, 11th day — places him squarely in the late-Heian generation of Shingon zuibun-ki compilers. The work he produced, KR6t0185 Shèngyǔ jí, is a vivid date-stamped diary of kuden received over successive days at the Shōjōbō. The DILA Buddhist person authority records him under code A001115.
Surviving work in the Kanripo corpus: KR6t0185 Shèngyǔ jí (2 fasc., 1135 CE).
