A Japanese cast metal decorative object in archaistic bell / kotaku style, presented with its original wooden box and accompanying papers. The box inscription appears to read “cast copper” and “Kotaku,” with a signature reading “Shomin,” while the included printed material refers to Kobayashi Shomin and Shokosya of Osaka. The piece is designed in a stylised archaic form, with a cylindrical body, large open mouth, overhead loop handle, openwork side flanges, and richly cast geometric and taotie-inspired decoration. It is best understood as a decorative Japanese metalwork object inspired by ancient ritual bell forms, rather than being catalogued strictly as a functional temple bell. The accompanying biography card appears to read “Kobayashi Shomin” and mentions a Showa-period artistic career, including study under Kitamura Seibo and repeated Nitten selections. A Shokosya card is also included, with Osaka business information, supporting attribution to the Shokosya workshop or distribution through it. Condition: vintage used condition with minor surface wear, light scratches, patinated finish, and normal storage wear. No major breakage is apparent in the photographs. The wooden box and paper materials are included. Please judge the exact condition from the photographs. Dimensions: H 12 cm × W 10 cm × D 8 cm. Weight: 527.5 g.
