The family constitutes one of the most distinguished metalworking lineages of the period. Together with the Goto house, the are recognized as preeminent among sword-related artisans, yet in the making of they stand without rival. The lineage produced many celebrated masters, foremost among them Myoju, whose inventive originality and vigorous artistic spirit epitomize the era. Works bearing the two-character signature "" are encountered from time to time, clearly distinguishable from Myoju yet reflecting the school tradition. The earliest productions, appraised as Ko-, date from the close of the period into the era and demonstrate that the group's technical foundations were already firmly established before Myoju's maturity.
Myoju's divide broadly into iron and (soft-metal alloy) types, and in both form and design they display striking originality. Among the works, materials such as , , and brass are employed to bring out the underlying texture, achieving varied surface effects of great subtlety. Myoju is credited with originating - (flat inlay), thereby introducing a pictorial quality and opening an entirely new expressive dimension within the world of . The school's mastery of (moss-file ground finish) is equally celebrated: executed upon solid-gold plates, this treatment yields an abundance of calm beauty through exquisitely controlled modeling of the flat planes. Further hallmarks include the with hineri (twisted turned-back rim), bold stylization of motifs, and a subtle tapering of the contour from blade side to hilt side -- a careful provision characteristic of artisans who thoroughly understood and tosogu.
The are lauded for a virtuosity of filework that "defies adequate description," and their fittings are said to have enhanced innumerable celebrated swords with an elevated dignity. Solid-gold were frequently melted down during periods of upheaval, making surviving -period examples extremely few; each is therefore of exceptional documentary and artistic value. In the broader context of Kyoto metalwork, the , along with the Goto, Hirata, and Shoami groups, mutually influenced one another after the beginning of the period, and these interactions are reflected in evolving styles. The school's enduring significance lies in its fusion of technical mastery with the bold aesthetic sensibility of the age, producing works that fully manifest the aesthetic core of the mainline tradition.
