| Research Abstract |
In this project, we conducted an archaeological excavation at the Usu-6 site, Date city, Hokkaido, and general survey and mapping of topography in the neighboring area. The project aims to assess the relationship between human adaptations and the changes of natural environment, especially the volcanic activities and sea-level changes in the area along the bay of volcano for the past 10,000 years.
Our research provides the following results. First, the older age range of materials from the Usu-6 site places approximately similar chronological position of the Urahoro type potteries during the Initial Jomon, which dated between cal BC 6,240 and 6,080. This confirms that the Usu-6 site is one of the oldest known shell midden in Hokkaido. Second, we identify that the sector collapse of Mt. Usu, forming the hummocky hill located the Usu-6 site, is dated at least before cal BC 17,620〜17,480, although it was previously thought to be between 9,000 and 7,000 yrs BP. Third, the analysis of available faunal remains suggests that the Initial and Early Jomon peoples brought abundant oysters collecting at the shore reef into the Usu-6 site. After that, they heat-treated their oysters around the rock shelter No.2, and abandoned them around the adjoining rock shelter No.1. Finally, we reveal that rock shelters had been used intermittently as the location of temporary camps in hunting from the Late to Final Jomon.
