Mihara Masaie

Mihara Masaie and the Mihara School of Bingo

Mihara Masaie was a swordsmith who was active in Bingo Province (present-day Mihara City, Hiroshima Prefecture) from the Nanboku-chō period into the early Muromachi period, and is one of the most renowned master smiths of the Mihara school. The Mihara school is said to descend from the Yamato tradition, and it continued to maintain its own Yamato-style character in an age when the Bizen tradition and the Sōshū tradition were at their height. As a key point on the San'yōdō, Bingo Mihara was a center of transport and trade, and as a place for sword-making it was also a land blessed with a supply of iron sand and charcoal.

The period in which Masaie was active was a transitional one, following the upheavals of the Nanboku-chō period, when the Muromachi shogunate was beginning to enter a stable phase. In Bingo during this period, the Mihara school held a distinctive position amid the cultural pull of the influence of the Osafune school of neighboring Bizen to the east and the Yamato tradition. Although he lived within this complex cultural environment, Masaie chose to continue to uphold the essence of the Yamato tradition.

Pure Preservation of the Yamato Tradition

The most striking feature of Mihara Masaie's blades is their fidelity to the technical and aesthetic essence of the Yamato tradition. The hamon is based chiefly on suguha, mixed with ko-gunome and ko-midare, and displays the dignified finish, centered on nie, that is peculiar to the Yamato tradition. Its nioi is deep and the hamon edge plump and soft; this hamon aesthetic, moving toward introspective depth rather than showiness, presents a serene world that stands in polar contrast to Bizen's chōji and Sōshū's hitatsura.

The jigane is fine mokume-hada, also called uzura-moku and Mihara-hada, and because half of the hira near the shinogi appears white, it is also called "Mihara no bun no kitae."

Form and Use

Masaie's blades are said to be characterized by high shinogi and thin mune-kasane, and some are shōbu-zukuri. The Mihara school was initially regarded as lower-grade work (gesaku), but it gained prestige for sharpness after the Ōnin War (1467). In the Edo period, the first Masaie was ranked Ō-wazamono and the fourth Masaie Saijō Ō-wazamono.

Spread and Successors of the Mihara School

Masaie's lineage produced many successors, including Masahiro, and sword-making continued steadily in Mihara throughout the Muromachi period. The Masaie name is said to have continued for nearly 300 years, until the end of the 16th century. This long continuity demonstrates the effectiveness of the path that Mihara Masaie established: a practical Yamato tradition rooted in its region.

TOUKENZA and Mihara Masaie

TOUKENZA introduces Mihara Masaie in order to recognize the sincerity of the regional development of the Yamato tradition. Masaie's choice to continue to uphold the serene Yamato suguha in the Bingo region, neither the brilliant Bizen chōji nor the magnificent Sōshū hitatsura, was not mere conservatism but a clear statement of position within the aesthetics of swords. Its understated beauty continues, even today, to carry a quiet but certain persuasiveness.
