I found this while cleaning out my grandmother's house. I think it's quite old. It's a long-term, unused item. Soma-yaki is a type of pottery made in the Soma region of Hamadori, Fukushima Prefecture. It has a unique double-walled structure, like a thermos, which keeps sake from getting cold easily. It seems that the kiln, Matsusuke-gama, has been manufacturing in Beppu City, Oita Prefecture since the earthquake (according to information on the internet). -------------------------------------------------- The following is a quote from the internet: [Features of Ohori Soma-yaki] * It is a pottery with a blue-green glaze that has large cracks, and the cracks spread throughout the vessel to create a pattern. * A painting of a galloping horse is hand-drawn. * It is a pottery with a simple, rustic taste, nurtured by the rich climate of the Tohoku region. The following is an explanation generated by Mercari AI: A set of tokkuri (sake bottle) and ochoko (sake cups) with a blue-green glaze and black patterns. * Set contents: Tokkuri and 6 ochoko * Design: Blue-green glaze and black patterns * Material: Ceramic * Box condition: With original box * Features: Glaze finish with crack patterns
