A mukōzuke (serving dish) of Ko-Kiyomizu, fired in the late Edo period. The vessel forms an inventive shape, gently drawn inward on all four sides, with two opposing edges articulated into folded pleated ridges. In the well, a boldly rendered yoroke-jima mon (zigzag stripe motif) is painted in iron-brown slip, its centre opened into a lozenge-shaped reserve. The interior of the foot bears the incised mark, kiln name Iwakura.

This mark is attributed to the Iwakurayama kiln, associated with the Awataguchi lineage of Kyo ware potters and noted for a particularly refined strain within Old Kiyomizu production. While the striking compositional structure draws the eye, the decision to rely solely on iron painting—eschewing polychromy—reveals a restrained aesthetic characteristic of Kyo ware. The softly toned surface, gently coloured through long use, together with a fine network of crackle, contributes a quiet warmth that is central to the appeal of the piece.

Across the set of five dishes, minor repairs or small chips are present at the corners; one example shows a small chip to the foot.
