This is a Bizen-yaki tokkuri (sake bottle) by Mr. Tsuyoshi Kaneshige, the grandson of Living National Treasure, Mr. Toyo Kaneshige. This piece is covered in a large amount of ash that was placed horizontally in front of the fire, and is a unique and magnificent work that was exposed to intense flames. The size is approximately 9.5 cm in diameter and 15 cm in height, making it an easy-to-use size. Thank you for viewing.
