Wakizashi Koshirae with Tomiyuki Tsuba and Fuchi-Kashira, Black Lacquer Saya

The Hamano school of machibori carving was established in mid-Edo Edo by Hamano Masazui (浜野政隨), commonly known as Tarōbei, an exceptionally gifted pupil of Nara Toshihisa. As the Edo Kinkō Meifu states of him that he "thunders through the world," Masazui won widespread renown as one of the "Four Guardian Kings of Nara" (Nara Shitennō). Training many disciples and employing numerous art names—including Otsuryūken, Aji-zumi, Kankei, Rifūdō, Yūkotei, Shūhōsai, Hankei-shi, and Isshunan—he formed what came to be known as the Hamano school, establishing one of the principal lineages of machibori artistry and founding an independent house. " Works are rendered by means of yōbori (sculptural carving) upon varied grounds—gold-and-silver imo-tsugi-ji, solid gold (kinmuku)—with details frequently treated in the in'yō-kon mode, suggesting the early Gotō masters as models.

The carving is executed with "ample, well-judged volume (nikudori)" and "exceptionally full, weighty presence," while applied metal (okigane) in silver and shakudō with shakudō iroe tightens pictorial fields and imparts additional movement. Later Hamano artists such as Katsurano Akafumi maintained this technical versatility, favoring polychrome inlay applied to high-relief compositions. " The NBTHK repeatedly notes that works "clearly demonstrate the high level of technique," "amply demonstrate advanced technical mastery," and possess "a composed dignity"—attestations to the school's sustained excellence across generations and its enduring place within the broader machibori tradition.
