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.
