Cord-marked pottery is the characteristic ware of the earliest inhabitants of Japan and one of the oldest potteries in the world. The Neolithic people known as the Jomon (cord-marking) culture, lived off the abundant fishing and hunting on the Japanese islands from at least the tenth millennium B.C., the “Incipient Jomon” phase, surviving in some areas until the third century A.D. During this period handmade utilitarian wares were treated with inventive, often extravagant artistry, and regional separations between groups resulted in a wide range of types and styles. This earthenware food vessel is remarkable for the fine quality of its clay and its sophisticated decoration. All Jomon pots were made by hand, without the aid of a wheel, the potter building up the vessel from the bottom with coil upon coil of soft clay. As in all other Neolithic cultures, women produced these early potteries. The clay was mixed with a variety of adhesive materials, including mica, lead, fibers, and crushed shells. After the vessel was formed, tools were employed to smooth both the outer and interior surfaces. When completely dry, it was fired in an outdoor bonfire at a temperature of no more than about 900° C.
Adamadai Shell Mound is a shell mound located in Chiba prefecture. It was discovered in 1894 (Meiji 27), and has been excavated several times. A number of potteries, stone implements, and shell bracelets, as well as many animal bones, have been unearthed there. It is a valuable site for the study of the history of the Kantō area and the investigation of the Middle Jomon period. The government has designated it as a place of significant historical interest. Adamadai type pottery is characterized by its elements and its shape. There is a great deal of mica in the clay. The cord-marks are on the body of the pottery, which generally has four grips on the lips. In these respects, this particular jar is of typical Adamadai type, but the three wave design on it is rather rare.
