Description

## Miyairi Norihiro — A Modern Smith Inheriting the Master's Spirit Miyairi Norihiro is a contemporary swordsmith who trained under the Living National Treasure Miyairi Shōhei (Miyairi Yukihira), working from a base in Nagano Prefecture. Just as his teacher Miyairi Shōhei devoted his life to reviving the Yamato-den and Yamashiro-den traditions, Norihiro has carried forward that spirit in his own commitment to transmitting and developing the traditional Japanese sword in the modern era. Holding the highest "Mukansa" (exempt from screening) certification in the sword evaluation system of the Society for the Preservation of Japanese Art Swords (NBTHK), Norihiro's technical mastery is widely recognized throughout the sword world. He applies the techniques and spirit cultivated in his teacher's workshop to his independent swordmaking, earning particularly high regard among contemporary smiths. ## The Spirit of the Miyairi School — Reviving Yamato-den and Yamashiro-den Miyairi Shōhei was a Living National Treasure swordsmith who took as his life's mission the revival of Yamato-den and Yamashiro-den techniques from the old-sword (kotō) period. His achievements — including the revival of the suguha (straight temper line) characteristic of Yamato-den, and jigane research based on analysis of ancient iron from the Shōsōin treasury — greatly expanded the possibilities of modern Japanese swordmaking. Norihiro trained under this master for many years, deeply internalizing the core techniques of Yamato-den and Yamashiro-den. More than simple technical inheritance, he has made his own the ideal that Miyairi Shōhei pursued — the "modern recreation of the spirit of the old sword" — and uses this as the axis of his own swordmaking. ## Blade Characteristics — The Dignity of Yamato-den and Yamashiro-den Miyairi Norihiro's works demonstrate at a high level of completion the Yamato-den and Yamashiro-den style inherited from his teacher Miyairi Shōhei. The jigane shows fine ko-itame and ko-mokume forging, richly covered in ji-nie for a moist and vivid surface. Inheriting his master's ideal of reviving the vitality of old swords for the modern era, Norihiro's jigane achieves a refinement that far surpasses the standard expected of modern swords. His hamon centers on suguha and ko-midare with deeply worked nie and dignified finish. The interior activity characteristic of Yamato-den — nie, nijūba (double temper), uchinoke, and more — appears throughout, demonstrating the reliability of the techniques inherited from his teacher. The overall effect carries an archaic dignity that seems impossible for a modern sword — a testament to the depth of the Miyairi school tradition. In shape, his works are upright and beautiful, with evident attention to recreating the proportional sense of old swords in modern blades. His work has received prizes at the Modern Sword Exhibition and New Masterwork Sword Exhibition, and his technical and artistic quality is highly regarded within the sword world and beyond. ## The Teacher-Student Bond and the Transmission of Tradition The career of Miyairi Norihiro — who trained as a student of the giant Miyairi Shōhei — is a living contemporary example of the Japanese sword's tradition of master-student transmission. The technique and spirit mastered under the teacher's strict guidance forms an unshakeable foundation for Norihiro's independent swordmaking, and from his works emerges simultaneously a firm individual identity as a modern smith and a sense of responsibility as the authentic inheritor of the Miyairi school tradition. After the passing of his teacher Miyairi Shōhei, Norihiro has come to occupy an important position in the contemporary sword world as one who carries forward the spirit of the Miyairi school — a standard-bearer of the Yamashiro-den and Yamato-den traditions in the modern era. ## DATEKATANA and Miyairi Norihiro DATEKATANA presents Miyairi Norihiro as a smith who transmits the spirit of the Living National Treasure Miyairi Shōhei into the modern era. The works and activities of Norihiro speak eloquently to the fact that the fundamental Japanese sword tradition of transmitting technique and spirit from teacher to student continues as a living practice in the present day. His works — in which the vitality of old swords and the techniques of modern swordmaking converge — are an important witness to the possibilities of the Japanese sword in the contemporary world.
