Onta-yaki, a traditional pottery from Hita City, Oita Prefecture. A sake cup that fits comfortably in the hand and has a simple, rustic feel, gaining character with use. Diameter: 5.5 cm. I think you'll find it doesn't get old and you can use it for many years. This is a gift. It has been stored in a dark place without being used. One cup has a chip on the rim, or perhaps it's part of the design, but it was like that from the beginning. Please refrain from purchasing if you are overly concerned about details. This is the "Village of Onta-yaki," a nationally important intangible cultural property, where everything is handmade, and it is the last pottery village in Japan.
