“…11). In addition, an analysis of broken trapezoids suggests that hunting weapons were repaired at the Doteue site, as a high proportion of broken trapezoid bases were found at the site (Yamaoka 2010(Yamaoka , 2012a. Striations running parallel to the working edges were also found on some obsidian trapezoids from the site.…”

“…Striations running parallel to the working edges were also found on some obsidian trapezoids from the site. Their distributional patterns indicate that obsidian trapezoids were used for cutting or sawing soft materials (Yamaoka 2012a). The trapezoids were thought to have been used for butchering or processing animals (Yamaoka 2020b).…”

This paper presents archaeological research of the Early Upper Paleolithic in the Japanese Islands, introducing the findings of recent research there into early modern humans. The authors provide background to the natural environment of the Upper Paleolithic while offering an overview of research in the area. Five important research topics, related to behavioral modernity of early modern humans, will be described. Based on them, new information and perspectives about the behavioral patterns of early modern humans are discussed with a focus on the Mt. Ashitaka area.

“…These stone tools were used for hunting mammals (Norton et al, 2010), which was conducted in groups, occasionally using trap-pits (Sato, 2012). Trapezoids are a type of flake tools and a chronological marker for the Early Upper Palaeolithic (EUP ; earlier than 30 ka) of this region (Kudo and Kumon, 2012 ;Morisaki, 2012 ;Yamaoka, 2012 ;Izuho and Kaifu, 2014), while kakusuijo-sekki, denticulated points with triangular cross-section, can be used as a marker of the earlier phase of the Late Upper Palaeolithic (LUP ; 30 to 18/17 ka). Backed blades are the most common tools during the EUP and LUP (38 to 18/17 ka).…”

“…Since Palaeolithic human remains are rarely preserved in this archipelago, stone tools (e.g., Tsutsumi, 2012 ;Yamaoka, 2012Yamaoka, , 2014 for some recent works in English) and spatial traces such as lithic scatters (Izuho et al, 2009) and trap-pits (Sato, 2012) have been treated as the major sources for the study of UP human behaviours and societies. The spatio-temporal correlation between the development in lithic technologies and the environmental change was also discussed (Sato et al, 2011 ;Morisaki, 2012 ;Morisaki and Sato, 2014).…”

An ecological niche modelling of Upper Palaeolithic stone tool groups in the Kanto-Koshinetsu region, eastern Japan

Ecological niche modelling (ENM) is a computer-based method to extrapolate the niche probability of a species through machine learning using (1) known location of a species' occurrence and (2) environmental factors such as temperature, precipitation and elevation. ENM is applicable to prehistoric archaeology based on the assumption that human behaviour and niche constructions were largely constrained by environmental factors. This paper applies ENM to a large-scale data of Upper Palaeolithic (UP) occupations in the Kanto-Koshinetsu region of eastern Japan in order to quantitatively assess and visualise ecological niche of UP populations to understand their behavioural strategies. Spatial niche probability was calculated with reconstructed palaeoclimatic data and landform indices for the Last Glacial Maximum (21 ka), taking into consideration four major lithic groups (trapezoids, kakusuijo-sekki, backed blades and microliths), which may reflect different strategies in resource procurement. Results indicated that niche probability was generally high in Musashino, Sagamino and Shimousa uplands in the southern Kanto region, although the observed site distribution was probably biased by intensive rescue excavations due to urban developments. The distance to the obsidian outcrops in the central highland remarkably contributed to the model. A closer look revealed two patches of high niche probability area in the Hakone mountains for the kakusuijo-sekki, backed blades and microliths. These patches were probably parts of a 'niche corridor' in association with the transportation of obsidian raw materials between the central highland and Hakone area via the Fujikawa valley.
