Sakakura Gon'noshin Terukane was the second-generation Echigo no Kami Kanesada. He studied under the first-generation Echigo no Kami Kanesada, succeeded to his position, and at first signed under that name. However, when the first generation's biological son Iwamatsu came of age, he yielded the Kanesada name and thereafter signed "Sakakura Gon'noshin Terukane." The change is documented by an extant work inscribed "Sakakura Gon'noshin Terukane; Echigo no Kami Kanesada, retired" with a reverse date of "an auspicious day in the second month of Enpō 8" (1680). Among the Osaka smiths, the consistently place him as possessing "excellent technical ability," with workmanship that is "notably free of unevenness or coarseness." His technical skill "has long been regarded as ranking immediately after Sukehiro and Shinkai."
Terukane's dominant mode is the tōran-midare -- the billowing-wave temper modeled after Tsuda Sukehiro -- yet the descriptions identify several features that distinguish his interpretation from its prototype. The large ō-gunome-midare characteristically incorporates -like (arrow-nock) forms and a distinctive shape referred to as katayama-, unique to this smith. A habitual mannerism appears below the , where "about three appear in succession." The forging is invariably a tightly packed with extremely fine adhering thickly and fine entering well. Whatever the chosen pattern -- and more rarely he produced works in large , , or even a rosary-bead-like () temper recalling Nagasone Kotetsu -- "it is typical that the is deep, the adheres well, and the is bright." His construction also bears distinctive marks: a steeply formed (), comparatively little , and a high -- features that the repeatedly notes as "points of interest" particular to Terukane. The begins consistently with a , after which thick, long enter well; runs broadly throughout the temper; and and appear with a frequency that one notes exceeds "his usual works." In his most accomplished pieces, rounded bead-like "resembling spray" (shibuki) are tempered within the tōran-like pattern, harmonizing with the wave-like rhythm to striking aesthetic effect.
Across nearly twenty designations spanning three decades, the evaluative consensus is emphatic: Terukane was a master of the Osaka tradition whose output was "consistently high in quality, without marked unevenness." His range extended from the bold tōran-midare that constituted his greatest forte to rarities modeled on Go Yoshihiro and the Sōshū-den, each "finished with consummate skill." The deep , thickly adhering , the conspicuous activities of and , and above all the brightness and clarity of the are cited in every assessment as the hallmarks by which his work may be identified, securing his place as "a solid mainstay within the Osaka tradition" and the foremost heir of the Kanesada line.
