The Ryokai school (了戒) took shape in the late-Kamakura capital of Kyoto, in Yamashiro Province, around the smith Ryokai, who worked through the era names Shoo, Einin, Kagen, Enkyo and Ocho at the turn of the fourteenth century. The old account makes him a son or a pupil of Rai Kunitoshi, and one version has him adopted into Kunitoshi's house; because his dated blades place him almost level with Kunitoshi, however, the NBTHK reads him more naturally as a contemporary (an aitedeshi, a fellow disciple) who formed his own line within the wider Rai circle.
