The Kawanishi Okhotsk site, Yubetsu, Hokkaido was excavated in 1991-1993 by Hokkaido Museum of Northern Peoples. At first, it was thought that this site belonged to the late period of the Okhotsk Culture. But close observation of unreported archaeological materials shows that this site belongs to the early and middle Jomon, the epi-Jomon, the Satsumon period and the middle and late period of the Okhotsk Culture. These unreported archaeological materials have an important information of the character of this site. So, this paper introduces these unreported archaeological materials of the Kawanishi Okhotsk site. As metal products had been already introduced by other paper, this paper introduces the other materials: pottery, stone tools, bone, antler and tooth tools, and so on this time.
Unreported pottery indicate that this settlement was built between the end of the early Jomon period and the beginning of the middle Jomon period and people culturally acted on this site in the Satsumon period after the Okhotsk Culture period. And in this research of these unreported archaeological materials, many arrowheads and crude side-scrapers made of obsidian were found. And unprocessed obsidian round gravels were found in the pit house No.8, too. It is thought because people lived in this site could collect obsidian gravels on the lower section of the Yubetsu River having obsidian source Shirataki on upstream, obsidian stone tools were actively made in the Okhotsk Culture period.
In the future, these unreported archaeological materials will be analyzed in detail.
