This is a "guinomi" (sake cup) by Katsumi Eguchi, who runs the Koyamaji Kiln, specializing in washi-zome (Japanese paper dyeing), in Takeo City, Saga Prefecture. Many people may wonder where Koyamaji Kiln is, but Takeo City, Saga Prefecture, is a famous kiln that made its name in the distant Sengoku period as the Takeo Ko-Karatsu lineage. When I purchased this piece, Mr. Eguchi held important positions such as a Japan Traditional Art Crafts Exhibition audit committee member and a director of the Saga Prefecture Ceramic Art Association, and of course, he was a regular member of the Japan Kogei Association. Why not acquire a piece of his work, which features the unique washi-zome technique? The size is W and D 7.0 cm, and H is 4.8 cm. Thank you for reading this long description to the end. Today, I have discounted the price slightly.
