Jippō Ryōshū

Jippō Ryōshū (実峰良秀, 1318–1405) was one of Gasan Jōseki's five great heirs (*Gasan-go-tetsu*) and the founder of Nyoi-an (如意庵), one of the five sub-temples (Goin) of Sōji-ji whose abbots rotated as the head-temple priest, and a member of the *Gasan ni-jū-go-tetsu* (twenty-five major Gasan heirs)^[1]. English-language biographical detail beyond his institutional position is sparse; the Jippō-ha sub-lineage label is plausible but unverified in accessible sources.
