Tsuba: Mumei Umetada with Nozaraishi Design

The Umetada school is one of the most distinguished metalworking lineages of the Momoyama period, rooted in Nishijin, Kyoto, and claiming descent from the legendary Sanjo Munechika. The house served the Ashikaga shogunal family over successive generations, establishing deep foundations in the full range of sword-related arts -- swordmaking, blade carving (toshin-bori), the production of steel and fittings, the shortening of blades, the insertion of inlaid signature attributions (zogan-mei), and the making of mountings. " Myoju taught both Hizen Tadayoshi and Higo no Kami Teruhiro, and accepted commissions from the Toyotomi and Tokugawa houses as well as many daimyo families. An earlier stratum of production, appraised as Ko-Umetada, dates from the close of the Muromachi period and demonstrates that the group's technical foundations were firmly established before Myoju's maturity. The near-contemporary Mitsutada, though absent from formal genealogies, is conjectured to have been of senior standing within the circle; his works, executed on brass with an archaic dekoboko-ji ground, display "an even more classically archaic elegance" than Myoju's. Shigeyoshi, active from the Kan'ei through Genroku eras, carried the tradition forward into the mid-Edo period. The Umetada school's collective technical identity divides into two principal modes: iron works and soft-metal (irogane) works. In the iron mode, Myoju expressed geometric patterns -- sayagata, raimon, kasumi-kaminari-mon, and rinzu-mon -- by means of gold nunome-zogan, complemented by celebrated openwork including wheel and double-tomoe sukashi tsuba.

The nejikaeshi-mimi (twisted turned-back rim) and gold rim inlay are techniques "at which he particularly excelled," while the iron itself is invariably "carefully selected" and displays excellent quality. In the irogane mode -- employing shakudo, suaka, brass, and other alloys as ground material -- the school developed a distinctive form of hira-zogan (flat inlay) that retains only slight relief, deploying colored metals in novel combinations. " Ground textures including hammered tsuchime-ji, polished migaki-ji, and file-finished surfaces are deployed with meticulous care to heighten the pictorial effect. Mitsutada's work on brass with its uneven, raised-and-recessed ground and enrichment through gold and silver nunome-zogan represents a more archaic variant of this aesthetic. Shigeyoshi synthesized the inherited hira-zogan tradition with textile-derived designs of linked shippo, karakusa arabesque, and sayagata patterns -- reflecting his Nishijin milieu, the heart of Kyoto's silk-weaving district -- while deploying suemon-zogan, sukidashi-bori, and kin-iroe across shakudo grounds in both polished and stone-textured finishes. The Umetada school's historical significance is singular: the pictorial manner of design, the hira-zogan technique, and the use of non-iron metals as the ground material "all find their earliest beginning with Myoju" -- he stands as the originator of an entire aesthetic vocabulary in kinko. The NBTHK consistently describes Myoju's work as possessing "the vitality that preserves the very momentum of brushwork," with a "strong connection with Hon'ami Koetsu and Tawaraya Sotatsu" that places him among the foremost artistic figures of the Momoyama age. " Solid-gold tsuba, frequently melted down during periods of upheaval, are recognized as extremely rare survivals of exceptional documentary and artistic value. Learn more →
