Koizumi Nizaemon (小泉仁左衛門), Japanese

An Iron Teapot 

Showa Era (1926-1989)  

About the work

A finely crafted iron teapot by Koizumi Nizaemon, produced in the celebrated Takaoka tradition of iron casting. Elegant in both form and function, the piece reflects the restrained aesthetic and exceptional craftsmanship for which the Koizumi family has long been renowned.

The teapot features a tall, gently tapering cylindrical body with a warm, dark brown patina that displays a subtle, finely textured surface. Its gracefully elongated spout flows naturally from the body, creating a balanced silhouette, while the forged iron overhead handle provides both strength and visual harmony. The simple domed lid, finished with a small knop, complements the understated design and highlights the beauty of the hand-finished iron.

Free from excessive ornamentation, the teapot celebrates the inherent character of cast iron through its refined proportions and tactile surface. A crisp impressed seal beside the spout identifies the maker as Koizumi Nizaemon. The interior retains its traditional iron finish, intended to develop a natural protective patina through use while enhancing the quality of heated water.

Footnote

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.
