This item is believed to be an early work by Yamamoto Tōshū, a Living National Treasure of Bizen-yaki. It has been passed down to me from the previous generation. The "万 (man)" seal is also well-executed. It is thought that he studied various types of ceramics in his early years, and this Korean Joseon-era buncheong tea bowl may be one of his works. It is rare for a Bizen-yaki artist to create a Joseon-era buncheong tea bowl, so it could be a very rare item. Perhaps it is an extremely rare piece. The box was prepared to match the tea bowl, and so was the wrapping cloth. The photos are everything, so please examine them and make your own judgment. Please purchase only if you are satisfied and understand the item. The tea bowl is in good condition, but there is some age-related deterioration from home storage. There are no noticeable cracks or chips. There appears to be a thin crack-like line, but it doesn't feel like a crack when touched, so it is likely a glaze crack (nyū). Tea Bowl Dimensions (approx.): Height: 7 cm, Diameter (mouth): 10.5 cm, Diameter (base): 5.5 cm ❈ The price is set considering the value as a potentially unearthed, rare item. m(_ _)m ❈ Immediate purchase is welcome.
