Abstract: Tenjinyama archaeological site is located in Minamichita town of Aichi prefecture, Japan. In 1956, the site was excavated by the Department of Archaeology of Nagoya University. Jomon pottery of the Tenjinyama type that belongs to the later phase of Initial Jomon period was established from the archaeological pottery assemblages. However, the description of the excavation research and assemblages is yet to be reported. At the later phase of Initial Jomon period, the prehistoric surrounding environment was fluctuated, such as Jomon transgression and Kikai-Akahoya (K-Ah) eruption. The archaeological assemblages excavated from Tenjinyama site seem available for demonstrating behavioral changes during the environmental fluctuations. This study reports radiocarbon dates and stratigraphic contexts of lithic and pottery assemblages and examines the behavioral changes at the later phase of Initial Jomon period. Tenjinyama site was excavated by 10 cm arbitrary levels and by setting 11 grids, A–K. Pottery assemblages are changed through the stratigraphic layers. To divide into cultural layers from arbitrary layers, hierarchical cluster analysis was performed based on the frequency of pottery type. Technological attributes of pottery assemblages (thickness, shell striation, rim shape and temper) were compared during the cultural layers at B–C grids. As a result of cluster analysis, we classified into three cultural layers that consist of layers 1–7, 8–9 and 10–15, respectively. The total amount of pottery assemblages had been increasing between three cultural layers. It is possible that the utilization of Tenjinyama site had become vigorous until the abandonment of the site. Previous studies are different from our result in that Kikai-Akahoya (K-Ah) eruption negatively influenced the activities at the west side of Aichi prefecture. This study could provide a new viewpoint about behavioral changes at the later phase of Initial Jomon period.
