In this paper, we attempt to reconstruct the process by which Bizen Sue ware flowed into the palace capital in the early 7th century, the first half of the Asuka period. Among the large lids collected from the Sazarashi Nakaike Kiln in Setouchi City, Okayama Prefecture, we found one that closely resembles the lids unearthed in the southern part of the Nara Basin, the Asuka Fujiwara area, and it is now clear that Sue ware was supplied to the capital from the Bizen area in the eastern part of Okayama Prefecture. The supply of Sue ware from the Bizen area to the Asuka Fujiwara area may date back to the first half of the Asuka period. It has been suggested that the supply of Sue ware to the imperial capital became active in the latter half of the Asuka period, but the results of this paper clarify that the Bizen area was supplying Sue ware to the palace capital before such large-scale supply began. It is highly likely that the supply of Sue ware to the palace capital in the first half of the Asuka period became the basis for the mass supply seen in the latter half.
