The moulded and modelled figure of Benkei on carp has its mouth slightly opened, protruding eyes, moulded nostrils, raised fins, incised scales along the body. It is sitting on its curved caudal fin, the carp with a figure of a boy moulded with arms and legs gripping around its belly. The carp is leaping from a wave-shaped plinth, which was moulded separately.
The figure is decorated in overglaze polychrome enamels, the carp with mouths heightened in bright red, the fins and tail in gold, and traces of aubergine enamel painted on the eyes and along the body. The boy expresses an angry face, with eyes and nose heightened in brown, and mouth in bright red, wearing a headdress delineated in bright red, and a sort of cape, outlined in vivid red, and dotted in aubergine, green and black enamels. The hollow plinth is naturalistically moulded suggesting waves and painted in green and aubergine enamels. The plinth was moulded separately from the figure.
