| Research Abstract |
Anthropological study of the transition form the Jomon to the Yayoi Periods in northern Kyushu was performed using morphological and paleodemographical features. Northern Kyushu, the area of Japan located closet to the Korean Peninsula, has been considerably influenced by foreign culture and immigrants for the Asian mainland in the past. The feature of Yayoi people in this region has been attributed to a genetic influx of immigrants from the Korean Peninsula or China . However, several important questions require further scrutiny concerning with the transition from Jomon to Yayoi peoples, especially in the early stages of the supposed immigration into this region. The main difficulty in solving these questions concerning with the transition during these periods in the northern Kyushu has been the lack of suitable skeletal materials belonging to the time between the two periods. Therefore, it is unclear who the first rice agriculturalists in Japan were. In other words, which group of people is responsible for the "Yayoi revolution", including new culture and full scale rice agriculture, the native Jomon people or a new immigrant group? Because it is difficult to discuss this problem directly due to scarcity of skeletal remains from these periods, we attempt a reconstruction of this transitional period in northern Kyushu, by paleodemographic and morphological analyze. Judging from the results by population genetic analysis, it is reasonable to suppose that a small number of people initially migrated form the Asian mainland in early stage, which is consistent with the archaeological data. Following this the size of the immigrant population increased substantially and they, not the native Jomon people, played a principal role in the development of the Yayoi culture from its inception.
