The ‘Palaeolithic Sites in the Japanese Islands’ database (JPRA-DB), published in 2010, includes 16,771 archaeological occupations during MIS 2 (22 to 11 k.a.). The information was compiled from 9,141 excavation reports. GIS-based data mining of JPRA-DB promises to quantify and visualise the geographic range of late Palaeolithic hunter-gatherers to the most reliable extent ever. This paper presents an application of eco-cultural niche modelling to analyse the geographic preference of different lithic tradition groups in the Kanto region, East Japan, in response to the palaeogeographic and palaeoclimatic settings in MIS 2.
