NBTHK Setsumei

Juyo-Token, 60th Session — Designated October 16, 2014 Katana, mumei: Omiya (大宮) Measurements Nagasa 69.3 cm, sori 1.0 cm, motohaba 3.0 cm, sakihaba 2.2 cm, kissaki-nagasa 3.6 cm, nakago-nagasa 19.8 cm, nakago-sori 0.1 cm Description Keijo: shinogi-zukuri, iori-mune; somewhat wide mihaba with little difference between moto and saki width; thick kasane; shallow sori; elongated chū-kissaki. Kitae: itame-hada mixed with mokume and nagare-hada; abundant ji-nie (dense nie in the ground), with plentiful chikei; a faint utsuri appears. Hamon: A mixed temper of small notare, gunome, chōji, and togariba, with some angular turns; at times showing saka-gakari; with ashi and yō; nioi-dominant with ko-nie; accompanied by kinsuji and sunagashi, and with small tobiyaki. Boshi: On the omote it enters in midare-komi; on the ura it enters in notare-komi; a small tobiyaki appears above the yokote; on both sides it turns back with a pointed tendency. Horimono: Bō-hi on both sides, carved kaki-nagashi. Nakago: ō-suriage; kiri-jiri; file marks kiri; three mekugi-ana; unsigned. Artisan Omiya school Era Nanbokuchō period (koto) (inferred) Explanation The Omiya group of Bizen Province is traditionally said to have originated when the school’s founder Kunimori (国盛) moved from Inokuma Omiya in Yamashiro Province to Bizen. Kagemori (景盛), who cut long signatures such as “Bishū Osafune Kagemori” (備州長船景盛), has long been regarded as the school’s representative smith. In recent years, however, a new theory has emerged: based on shared stylistic traits and the common feature of cutting certain characters in reverse, Kagemori is understood as a collateral Osafune smith belonging to the lineage of Chikakage (近景) and Yoshikage (義景). From this perspective, it has been proposed that the smiths who cut powerful, large two-character signatures such as “Morikage” (盛景) or “Mori” (盛) may in fact represent the true Omiya smiths in the sense of inheriting Kunimori’s direct line—thereby prompting a re-examination of the conventional view. This katana has a somewhat wide mihaba with little taper from base to tip, a shallow sori, and an elongated chū-kissaki. The forging shows itame mixed with mokume and nagare-hada; abundant ji-nie adheres, chikei appears well, and a faint utsuri can be seen. The hamon blends multiple elements—small notare, gunome, chōji, and togariba—and is at places slightly angular, with occasional saka-gakari. Ashi and yō enter, the temper is nioi-dominant with ko-nie, and kinsuji, sunagashi, and tobiyaki appear. The bōshi runs into midare-komi and shows a pointed tendency in the turnback. These features clearly express the distinctive characteristics of the Omiya school. The blade is preserved in kenzen (sound and well-preserved) condition in both ji and ha; with thick kasane and ample nikuoki, it is a dignified and imposing work. Additionally, it is recorded as a prefectural designation (Board of Education), No. 5739, dated October 16, 1953.

›

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. Learn more →

Kitae: itame-hada mixed with mokume and nagare-hada; abundant ji-nie (dense nie in the ground), with plentiful chikei; a faint utsuri appears.
