The name Sukeyoshi belongs to several smiths working across the Bizen Ichimonji tradition, spanning from the mid-Kamakura period through the Nanbokucho era. The most celebrated bearers of this name are found within both the Fukuoka Ichimonji and Yoshioka Ichimonji lineages. The Fukuoka Ichimonji Sukeyoshi, active in the mid-Kamakura period, is associated with the brilliant, large-patterned o-choji-midare that defines the school's finest era. The Yoshioka Ichimonji Sukeyoshi, whose signed works bear dates such as Ryakuo 2 (1339) and Sadawa 5 (1349), flourished from the late Kamakura into the Nanbokucho period as the Yoshioka branch supplanted the earlier Fukuoka group. Reference works record that he was a son of Sukekichi, and he is also identified with the longer signature "Bishu Yoshioka-ju Saemonnojo Sukeyoshi." A separate Sukeyoshi is also associated with the Senjuin school of Yamato Province, one of the oldest among the five Yamato traditions, where signed works remain exceedingly scarce. Additionally, an Osafune Sukeyoshi is known from a blade bearing the six-character signature "Bishu Osafune Sukeyoshi."
The Yoshioka Ichimonji Sukeyoshi's characteristic style, as the NBTHK consistently observes, departs from the flamboyant brilliance of Fukuoka Ichimonji. Within the choji-midare, gunome stands out conspicuously, and places where the pattern inclines in reverse (saka-gakari) or where a somewhat compact, subdued quality (kozumu) enters the edge are noted as distinguishing points of appreciation. The kitae typically shows itame-hada with prominent midare-utsuri, and the temper is nioi-dominant with ko-nie. The Fukuoka Ichimonji Sukeyoshi, by contrast, displays the school's celebrated large-patterned choji-midare with tobiyaki, kinsuji, and sunagashi. The Senjuin Sukeyoshi exhibits flowing, piled itame-hada with ji-nie and an utsuri-like effect, with a richly complex hamon interweaving ko-choji, linked ko-gunome, notare, and gunome in strongly nie-laden workmanship featuring nijuba, yubashiri, and hakikake in the boshi -- hallmarks of the Senjuin school.
Across these lineages, the designation records consistently emphasize the rarity and documentary value of signed Sukeyoshi works. The Senjuin example is praised as standing out among that school for its "stout, weighty, and powerfully masculine appearance" and its provenance through the Matsuura family of Hirado domain. The Yoshioka Ichimonji works, whether bearing the Ryakuo date inscription or the rare kanmuri-otoshi-zukuri tanto dated Gentoku 3 (1331), are valued both for their typicality as exemplars of the school and as precious reference material. Extant signed works of both traditions have remained scarce, and those that survive are recognized as important evidence for understanding the full breadth of the Bizen Ichimonji lineage across its several centuries of production.
