The Pioneer Phase of Obsidian Use and the Emergence of Modern Human Behavior in the Japanese Archipelago

在日本的人类活动的确凿考古证据发生在约。40ka口径BP与此同时，在海拔1500米以上的山区，并在太平洋上发现了黑曜石，并开始利用它作为非当地的石质原料。第一批定居者对广阔地区的自然资源环境进行了全面调查，可能引发了对难以找到的黑曜石资源的开采。黑曜石使用的开始是现代人类从非洲扩散到远东欧亚大陆和日本列岛出现“现代人类行为”的考古证据之一。

Unequivocal archaeological evidence on human activities in Japan occurred in ca. 40ka cal. BP. At the same time, obsidian sources in mountainous areas over 1500m a.s.l. and on the Pacific discovered and the utilization of obsidian as a non-local lithic raw material begun. Comprehensive surveys for natural resource environment across a vast area conducted by the first settlers likely triggered the exploitation of obsidian sources in the places difficult to find. The beginning of obsidian use is one of archaeological evidence indicating the date of modern human dispersal from Africa into Far Eastern Eurasia and the emergence of "modern human behavior" in the Japanese Archipelago.
