This is an Ibe-de Bizen Tokkuri (sake bottle). From 【Bizen Ware】 Products of the largest pottery area in the Chugoku region, centered around Bizen City (formerly Ibe Village) in southeastern Okayama Prefecture. It is commonly called Ibe ware, but strictly speaking, after the Keicho era (1596-1615), finely sieved soil was used, and thin, blackish-brown works with applied clay were called Ibe-de. Bizen ware is a general term for a wide range of national kilns. Its origins are in the Sueki kilns (Oku Ancient Kiln Site Group) that developed in Oku-gun, Oku-cho, Osafune-cho, and Ushimado-cho from the 6th century onwards. This was found while cleaning the storehouse for renovation. I am not familiar with it, but it was given to me from my grandfather's collection and is old. If you like it or are looking for one, please consider it. #ToriArt
