About the school
Omiya School大宮派
The Omiya school (大宮) of Bizen traces its name and its blood to Kyoto, not to the Bizen heartland where it eventually settled. The published sources follow the line back to a remote ancestor, Kunimori, who is said to have left Inokuma Omiya in Yamashiro province and moved into Bizen during the Kamakura period, around the Bun'o years. With him the group carried a Yamashiro sensibility into the province of *choji*, and that transplanted origin remains the key to everything the school later became. Works by the earliest Omiya hands, Kunimori and Sukemori, survive in extremely small numbers, so the line first comes clearly into view at the close of the Kamakura period and then flowers through the height of the Nanbokucho era. Several names recur across these generations, among them Morishige, whose name passed down successive smiths from the late Kamakura into the Muromachi period; but the figure who left by far the largest body of work, and the highest reputation, is Morikage, who worked at Osafune and cut long, dated signatures such as Bishu Osafune Morikage across the Oan, Joji, Eiwa and Kakei years. What binds these smiths into a recognizable group is a particular blend, a temper that reads as *Soden-Bizen* yet is built differently from the clove-flower of mainstream Osafune. The *jigane* is the constant beneath the range: a standing *itame* mixed with *mokume*, the grain tending to open, with fine *ji-nie*, *chikei* entering, patches of *jifu* in the steel, and a Bizen *midare-utsuri* that rises on signed and *mumei* blades alike. Upon that ground the school sets a *midare* in which *gunome*, *choji* and an angular, pointed tendency intermingle, with *ashi* and *yo* entering well, *nioi* deepening to *ko-nie*, and fine *sunagashi* and *kinsuji* running through the *ha*. The recurring tells are a Yamashiro-tinged *ji* carrying that strong *nie*, and a *boshi* running *midare-komi* to a small round or a pointed turnback with *hakikake*. Within this shared vocabulary the hands diverge. Morikage tends to a *ko-notare* base with somewhat angular crests and a subdued, *shizumi* *nioiguchi* rather than a showy temper, while his range stretches from that quiet register to a *suguha* the commentary likens to Aoe and the Unrui smiths. Morishige favors a bold, opened-waist *gunome*, the *koshi-hiraki* pattern mixed with *choji* into flamboyant undulations. The breadth itself is a school trait, the published sources describing the Omiya *saku-iki* as wide, taking in *notare*-dominant work, florid *choji-gunome* *midare*, angular *gunome*, and the Aoe-manner *suguha* at its quiet edge. To *kantei* an Omiya blade is to read this fusion of *Yamashiro-den* refinement and *Bizen-den* flamboyance, then to separate it from its larger Osafune neighbors. The bright *midare-utsuri* and the *nie*-strong *ji* hold the school apart from Kanemitsu, whose temper undulates more broadly, and from the box-shaped large *midare* of Chogi, though the kinship to Chogi is real and acknowledged in the commentary, which places Morikage's workmanship beside it. The school is often overshadowed by those two names, which makes the distinguishing read the more useful: the standing *itame* with its *utsuri*, the angular pointed elements, and the comparatively restrained *nioiguchi*. Morikage stands at the front rank of Nanbokucho Soden-Bizen and carries a Jo-jo saku grade in Fujishiro; his provenance runs through the daimyo houses, the Nabeshima of Hizen, the Uesugi, the Date and the Hisamatsu-Matsudaira, with a piece recorded in Imperial keeping. A modern scholarly question hangs over the name itself, the published sources recording a theory, now widely entertained, that the long-signature Morikage may belong to an Osafune collateral line connected to Chikakage and Yoshikage, and that the smiths who cut bold, large two-character signatures may be the true Omiya hands; the matter is left open. By the late Muromachi the distinctive Omiya traits fade, the Shinkuro generation of Morishige showing no difference from the general Sue-Bizen type, evidence that the subsidiary line was at last absorbed into the dominant Osafune school, a trajectory that gives the group its documentary value for the study of how Bizen's lesser lineages were drawn into the mainstream.
