What motivated early pottery adoption in the Japanese Archipelago: A critical review

摘要

A number of AMS radiocarbon dates, accumulated since the 1990's, reveal that ceramic technology first developed among non-agricultural, hunter-gatherer societies in the late Pleistocene of East Asia. Specifically, on the Japanese Archipelago the radiocarbon chronology indicates a diverse trajectory of pottery adoption. The earliest adoption of pottery here was by mobile hunter-gatherers, regardless of region and climatic event. On the other hand, pottery culture suddenly started to flourish later along the warmer Pacific coastline region of southwestern Japan just after the onset of climatic warming of the Late Glacial, and spread throughout the archipelago by the onset of the Holocene. Climatic amelioration, therefore, did not induce the 'beginning' of pottery use, but prompted the 'development' of sedentary lifestyles accompanying intensified use of pottery. This complicated situation clearly means that motivation and context of pottery adoption do not follow a simple explanation. However, recent studies of chemical and isotope analyses of charred residues on pottery indicate similar use of early pottery throughout the archipelago in the late Pleistocene and the early Holocene. This paper critically re-evaluates these issues through examining synchronic and diachronic archaeological contexts. Existing data indicate that there is great inter-regional variability in technology, subsistence, paleoenvironment, and adaptation associated with pottery, therefore the motivation for the adoption of pottery is distinct within various geographical, environmental, and temporal contexts in the archipelago.
