Koizumi Nizaemon (小泉仁左衛門)
Koizumi Nizaemon (小泉仁左衛門) holds a distinguished place in the history of Japanese metalwork. Since 1659, the family has been at the center of developing and perfecting Nanbu ironware (Nanbu tekki), a tradition deeply rooted in Morioka. Over generations, they established themselves as the leading producers of iron kettles (tetsubin), tea utensils, and other cast-metal works, combining technical precision with refined artistic expression. Recognized as innovators and custodians of cultural heritage, the Koizumi kettles—often decorated with auspicious motifs and inscriptions—remain highly prized by collectors, connoisseurs, and practitioners of the Japanese tea tradition.
