| Research Abstract |
(1) For this study, we excaved one CHASHI site in Esashi town in Hokkido, and four sites : Kogaizawa-yama site, Kuretubo site, Kuretubo II site and Subatto site in Nishine Town-all in Iwate Prefecture.
Kogaizawa-yama site, Kuretubo site, Kuretubo II site and Subatto site are all on the ridge of Highland about 300-500meters above sea level. At these sites, we excaved some pithouses, and we could see some Hajiki wares, a little Sueki wares, and several iron implements. In the result, I regard the age of this sites as the later 10th century from those Hajiki and Sueki wares. The important part of Kuretubo Site and Kogaizawa-yama Site are surrounded by moats and earthworks.
(2) In the result of on-the-spot surveys, there were many dwelling clusters on highland in Heian period in northern area of Iwate, Akita and almost area of Aomori prefecture, unknown to the academic society.
Those dwelling clusters are different from the general dwelling clusters on lowland without moats and earthworks. I consider they are very defensive dwelling clusters. To promote the study of dwelling clusters on highland in Heian period will make the connection of CHASHI-Ainu's fort-in Hokkaido and the background of ancient Emishi society that bred defensive dwelling clusters clear.
