Human cultures and environmental changes in the Pleistocene–Holocene transition in the Japanese Archipelago

Abstract: The accumulated archaeological records have shown that hunter-gatherer societies turned from mobile to sedentary ways of life through the transition from the terminal Pleistocene to the initial Holocene (ca. 15–8 ka) in Japanese Archipelago. This paper discusses the historical processes seen among prehistoric human cultures, societies, subsistence and environmental changes in this transitional period, namely the shift to the ‘Jomon’ culture. After the AT eruption, which is a huge volcanic eruption in Southern Kyushu in ca. 25000 14C BP, population contraction of large mammals as well as a rapid shift to cold/dry condition and expansion of coniferous forest pushed hunter-gatherers to change their hunting target from large mammals by broad foraging to middle to small mammals in small areas, and formed ‘matured’ regional societies. The ‘Jomon’ culture is thought to have stemmed from these societies, but is more varied, regional, and sophisticated than the Palaeolithic one resulting from the complex environmental change of the Pleistocene–Holocene transition. The emergence of oceanic climate and fine-grained ecological settings shaped the unique culture. For example, the spread of broadleaf forests supplied plentiful nuts, and continental shelves formed through coastal transgression furnished ample marine resources. Because these new ecological settings were formed, the ‘Jomon’ population could have become dependent on gathering and fishing, and shifted to a sedentary subsistence strategy. Furthermore, increase of precipitation and diverse rainfall patterns encouraged diverse ecological settings, leading to the formation of various regional Jomon cultures. This paper presents such complex trajectories for the ‘Jomon’ culture. [Copyright &y& Elsevier]
