Late Pleistocene hunter-gatherers in East Asia adopted pottery, yet the ability to reconstruct circulation, mobility, and exchange has been hampered, in part, due to problematic regional geochronology. The driving forces behind pottery adoption is unclear. The purpose of this study is to test our results of the first systematic petrographic pottery sourcing from the pre-Younger Dryas by utilizing neutron activation analysis. We examine samples from the Sankauyama I site on Tanegashima Island, southern Japan, dating to the Incipient Jomon, ca. 14,000/13,500-12,800 cal BP, with a well-defined geochronology. Our NAA results corroborate with the petrographic study suggesting that pottery was mainly produced in-situ, but some vessels were transported long distances from another island. Changing from high mobility, sedentary Incipient Jomon foragers made pottery, occasionally investing in long-distance ceramic vessel transportation and exchange likely involving ocean crossing. This may be associated with a risk-buffering strategy in the context of rising sea levels and isolation of Tanegashima.
东亚晚更新世的狩猎采集者采用了陶器，但由于区域性地质年代学存在问题，重建其流通、流动和交流的能力受到了阻碍。陶器采用的驱动力尚不清楚。本研究的目的是通过利用中子活化分析来检验我们首次对年轻仙女木期前进行的系统石器来源分析的结果。我们研究了来自日本南部种子岛 Sankauyama I 遗址的样本，这些样本的年代可追溯到约 14000/13500-12800 cal BP 的初始绳纹时代，具有明确的地质年代学。我们的 NAA 结果与岩相研究结果相符，表明陶器主要是在当地生产的，但有些容器是从另一个岛屿长途运输而来的。从高流动性、定居的初始绳纹时代的觅食者转变为使用陶器，偶尔会进行长途陶瓷容器运输和交流，可能涉及到跨洋活动。这可能与海平面上升和种子岛孤立的背景下的风险缓冲策略有关。
