A chamfered leg links the flat cup with the base. The rim of the cup opens wide. A band-like flat area surrounds the outer rim of the inner part and the center of the inner part slightly rises in the shape of a mountain. In the inner part, there are two layers of an oblique radial pattern and a spiral pattern inside it. An arc pattern is also applied from various directions on the outer surface of the base. The shape of the vessel and how patterns are applied to it suggest that this was created in the early Nara period, that is, in the early 8th century. The shape suggests that this hajiki (unglazed reddish brown earthenware) was created by following the example of a wooden takatsuki (tall cup). It is very rare that such a vessel was excavated from a place other than the ruins of a big castle town, such as Fujiwarakyo or Heijokyo. In addition, this one is a very valuable material in that the original form remains almost perfectly, except for a small part missing on the rim.
