Bizen ware is a type of Japanese pottery traditionally from Bizen province, presently a part of Okayama prefecture.  

Bizen is characterized by significant hardness due to high temperature firing; its earthen-like, reddish-brown color; absence of glaze, although it may contain traces of molten ash resembling glaze; and markings resulting from wood-burning kiln firing.
