This study examines subsistence-settlement systems and residential mobility of prehistoric Jomon hunter-gatherers in Japan. Raw data were collected from Moroiso Phase (ca. 5000 B.P.) sites of the Early Jomon Period in the Kanto and Chubu regions. Many archaeologists have assumed that the Jomon people were sedentary inhabitants of large villages, occupied throughout the year. However, recent developments in Jomon studies suggest that we must reevaluate the assumption of Jomon sedentism. In this study, Moroiso Phase settlement patterns, including intersite lithic assemblage variability, site size and site location, are examined in the context of an ethnographic model of hunter-gatherer subsistence-settlement systems. The results indicate that the Moroiso Phase settlement patterns correspond very closely to those of hunter-gatherers who are relatively sedentary but move their residential bases seasonally. Changes of settlement patterns over time within the Moroiso Phase are also examined, and the results are explained in relation to changes in the natural environment.

A paleodemographic analysis was conducted using skeletal data from Jōmon period sites in Japan. 15P5 ratios were produced as proxy birth rate values for sites throughout the Jōmon period. Previous studies based on numbers of residential sites indicated a substantial population increase in the Kantō and Chūbu regions in central Japan, climaxing during the Middle Jōmon period, followed by an equally dramatic population decrease, somewhat resembling changes that occurred during a Neolithic Demographic Transition (NDT). The Jōmon are viewed as a relatively sedentary, non-agricultural group, and provided an opportunity to attempt to separate the factors of sedentism and agriculture as they relate to the NDT. Skeletal data showed fairly stable trends in birth rates, instead of the expected increase and decrease in values. This discrepancy calls into question the validity of previous studies. The stable population levels suggest that sedentism alone was not the primary driver of the NDT. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection
