The Ōmiya group came to Bizen from Kyoto — Kunimori is said to have moved from Inokuma-Ōmiya in Yamashiro and put down roots at Osafune — and worked there from the late Kamakura through the Muromachi. Its representative smith, Morikage, cut bold long signatures in reverse-chisel strokes; around him the school built a brilliant, florid temper of gunome, ko-gunome, and "open-hipped" koshi-biraki, run through with kinsuji and sunagashi over a midare-utsuri ground. Set beside the mainline Osafune masters, Ōmiya work reads a touch rougher and more rustic — and that vigor, in both ji and ha, is exactly its appeal.

Morikage (盛景) — Mainline · 1356-1361. Jūbun, Jūbi, Tokujū, Jūyō. Morikage (盛景) of Osafune in Bizen Province is the most prolific and most accomplished smith of the Omiya lineage, a group traditionally said to have begun when Kunimori relocated from Inokuma Omiya in Yamashiro Province to Bizen. In recent scholarship, the NBTHK notes that "based on shared characteristics in workmanship and the commonality of the chisel-cut characters in signatures carved with a reverse chisel technique," Morikage is now understood to belong instead to a collateral Osafune line connected to the genealogy of Chikakage and Yoshikage, while the smiths who signed bold two-character signatures may represent the true Omiya inheritors of Kunimori's stream. Among Nanbokucho-era *Soden-Bizen* smiths, Morikage occupies a distinctive position: his output spans from the Enbun and Joji eras, with dated works extending to Oan 3 (1370) and Joji 3 (1364), firmly establishing his active period at the height of the Nanbokucho.
The NBTHK consistently emphasizes that "the range of work attributed to Osafune Morikage is broad": pieces dominated by *notare*; flamboyant *midareba* with varied mixtures of *choji* and *gunome*; works centered on angular *kaku-gunome*; and even *suguha* in an Aoe-like manner. The *jihada* characteristically shows *itame* mixed with *mokume*, tending toward *hada-dachi*, with fine *ji-nie*, abundant *chikei*, and a conspicuous *midare-utsuri*. Mottled, patch-like areas of *jifu* also appear -- a signature trait. The *hamon* varies from *ko-notare* with angular crests to brilliant *choji-midare* mixed with *gunome* and *togariba*; the tempering is predominantly *nioi-gachi* with *ko-nie*, and the *nioiguchi* shows a characteristic tendency toward *shizumi* -- a subdued quality that distinguishes Morikage from Kanemitsu's broader, more relaxed undulations. The *boshi* frequently enters in *midare-komi* with a pointed tendency and vigorous *hakikake*, sometimes rising in *tsukiage* or finishing in a flame-like *kaen* manner.
The setsumei repeatedly place Morikage among "the leading smiths of Soden-Bizen," noting that "compared with Kanemitsu, it conveys a slightly more rustic flavor." His powerful Nanbokucho-period forms -- wide *mihaba*, thick *kasane*, and imposing *o-kissaki* -- are praised for preserving the "archetypal Nanbokucho-period shape," and blades in *ohira-zukuri* and *naginata-naoshi* constructions are singled out as exceptionally rare and valuable. The dated examples, distinguished domain provenances -- the Nabeshima and Uesugi families among them -- and the documentary value of Morikage's distinctive *sakate* signature manner further elevate his standing as both a master craftsman and a critical figure in the study of Bizen sword-making lineages.

Morishige (盛重) — Mainline · 1368-1375. Morishige belongs to the Omiya group, a lineage founded by the smith Kunimori, who is said to have originally resided at Inokuma Omiya in Yamashiro Province before migrating to Bizen around the Bun'o era (1260--1261) during the Kamakura period. The group flourished most notably after the beginning of the Nanbokucho period, and among its members Morikage and Morishige are particularly well known. The name Morishige was carried by successive generations: the first appeared in the late Kamakura period, and smiths bearing the same name continued into the Muromachi period. Among examples on which the smith cut his place of residence, the inscription "Osafune" is seen, firmly establishing the group's association with the Bizen tradition. One later generation bore the common name Shinkuro, and his extant works are considered extremely few.
Morishige's forge work is characterized by *itame-hada*, sometimes with *nagare* tending toward the edge, upon which a faint *midare-utsuri* appears -- a hallmark of the Bizen lineage. The *hamon* takes as its principal motif a large, complex *gunome* described as *koshi-hiraki* -- an opened-waist pattern -- mixed with *choji*, producing bold and flamboyant undulations with *ashi* and *yo* entering throughout. The *nioi* is deep, *ko-nie* adheres well, and activities of *sunagashi*, *kinsuji*, and occasional *tobiyaki* are present. The *nioiguchi* tends toward being tight with *ko-nie* adhering, and the *boshi* is consistently *midare-komi*, turning back in *ko-maru* or with a pointed tip. Later-period works by the Shinkuro generation display none of the characteristic Omiya traits, showing instead no difference from the general Osafune Bizen type termed Sue-Bizen, evidence that the group had by then been fully absorbed into the Osafune school.
The NBTHK consistently praises Morishige's works for their *kenzen* (sound and well-preserved) condition of *ji* and *ha*, and characterizes the workmanship as flamboyant and attractive. His blades clearly demonstrate the characteristic style of the Omiya lineage, and they are recognized as excellent examples of that tradition. The trajectory of the Omiya group as reflected in Morishige's work -- from the distinctive opened-waist *gunome* of the Nanbokucho period to the eventual convergence with mainstream Osafune production in the Muromachi era -- provides valuable material for understanding the absorption of subsidiary Bizen lineages into the dominant school. Works bearing the Shinkuro name and dated inscriptions such as the Kyoroku era (1528--1532) are regarded as precious reference material for the study of this progression.
