This tea bowl shows the strongest influence of Dōnyū. Although it is generously sized overall, it is thinly crafted, with undulating contours at the rim, a slightly tapered body, and a flared lower section. The base is large, but the footring is narrow, and the hollowed-out area inside the footring is wide. The interior is made as wide as a Dōin tea bowl, and a tea pool is carved into the bottom.
The black glaze applied over the entire bowl is smooth and well-fused. As Ryōnyū himself described it as a “bamboo leaf design,” yellow patches resembling bamboo leaves can be seen—three on one side and two on the other. A medium-sized seal is stamped on the side of the foot, and three marks remain on the foot’s base. Ryōin has inscribed the following: “Black Tea Bowl with Bamboo Design, Raku Kichizaemon Seal.”
