The Hazama school (Hazama-ha 間派), also known as the Kameyama tsuba makers, emerged in the castle town of Kameyama in Ise Province from around the Genroku era (1688-1704). The school's founders were members of the Kunitomo (国友) family, originally matchlock gunsmiths (teppou kaji) who had lived in Omi Province. "[[c:2]] Works bear either the single-character signature "間" (Ma) or personal names such as Kunitomo Sadaei and Masaei (正栄), linking the school's named artisans to a shared workshop tradition rooted in the military metalworking crafts of the Kunitomo lineage. The Hazama school's defining contribution is sahari-zougan (佐波理象嵌), an inlay technique employing sahari, a distinctive alloy of copper, tin, and lead.
"[[c:4]] Techniques attested across the corpus include suemon-zougan (applied inlay), takabori takanikubori (high-relief carving) in shakudou, hira-zougan (flat inlay), and the yakite kusarashi (fired and corroded) surface treatment. "[[c:5]] The Hazama school occupies a singular position within the broader kinko tradition as the only lineage to have applied sahari inlay to tsuba production. " The school's origin as firearms craftsmen who transferred their metalworking mastery to a peaceful art form, and their creation of a decorative vocabulary without parallel elsewhere in tsuba production, secure their place as one of the most distinctive regional schools of the mid-Edo period.
