Following Yayoi earthenware came Haji ware of the Kofun period. The name Hajiki (Haji ware) actually comes from written records such as Wamyoruijusho and Engishiki of the Heian period, but the name is a general term for primitive unglazed earthenware made in the Kofun period and later. Like Jomon and Yayoi earthenware, Haji ware was formed by coiling and fired in oxidation at a low temperature, the forms following after those of the Yayoi period. Haji ware is broadly divided into ritual vessels and daily utensils, but the development of Sue ware had a great influence on function. Basically, Sue ware was used as storage vessels, and Haji ware was used for cooking.
