Tea jar with green and white glaze, Kasama Ware

Kasama ware reflects the area of Kasama in Ibaraki Prefecture, mainly in the form of simple, daily vessels like pots, jars, and sake bottles with the characteristic nagashi-kake technique (pouring black glaze over kaki-yu (persimmon-coloured glaze) or copper blue glaze over nukajiro-yu (bran-white glaze)) applied. Kasama vessels were typically used to store sake, soy sauce, tea leaves, grains and other foodstuff.
