The Enju school of Higo Province is said to have been founded by Taro Kunimura, traditionally regarded as the maternal grandson of Rai Kuniyuki of Yamashiro. From the late Kamakura period through the Nanbokucho period the school flourished greatly at Kumafu in Kikuchi District. Among its lineage were many highly skilled smiths, including Kuniyoshi, Kunitoki, Kunitai, Kunitomo, Kunisuke, Kuninobu, and Kunitsuna. As a school rooted in the Yamashiro Rai tradition yet active in the remote province of Higo, Enju represents one of the most important regional transmissions of the classical Yamashiro manner.

In general, the school's works "do not markedly differentiate into strongly individualized styles" and broadly resemble the Rai tradition. The forging frequently shows a conspicuous tendency toward masame, with areas of flowing itame-hada and nagare-hada; the steel characteristically takes on a somewhat whitish cast, and shirake-utsuri or nie-utsuri often appears. The hamon is typically a calm chu-suguha in ko-nie-deki, with ko-ashi entering; the nioiguchi shows a somewhat shizumi (subdued) tendency, and the activities within the tempered area are gentle and restrained. Along the habuchi, effects such as hotsure, uchi-noke, kuichigai-ba, and nijuba appear with quiet frequency. The boshi is a principal diagnostic feature: it runs straight before the roundness at the point becomes slightly larger -- tending toward o-maru -- while the kaeri is tempered comparatively shallow and short, sometimes ending in yakizume. Blades often retain a somewhat high shinogi and well-developed hiraniku, conveying a martial robustness beneath the serene surface.

The NBTHK consistently characterizes Enju work as possessing "a gentle, restrained charm" and "a serene calm" that distinguishes it from mainstream Rai production. The school's steel is praised for its "refined and polished" quality, and pieces displaying a bright nioiguchi are singled out as "especially fine" examples, precisely because brightness is not the school's default register. Works retaining deep wazori, thick kasane, and abundant nikuoki (blade flesh) are commended as "sturdily constructed so as to be thoroughly suited for martial use." The Enju manner occupies a distinctive position within the broader Yamashiro lineage -- quieter and more introspective than Rai, yet carrying a robust physicality that reflects its provincial, warrior-class patronage in Higo.
