Abstract
Human remains of the aeneolithic Yayoi period from the Shakameyama site in Ehime Prefecture, Taishaku-Nagoshi site in Hiroshima Prefecture, Karako-Kagi site in Nara Prefecture, Bishamon site in Kanagawa Prefecture, and Sano and Awajinsha sites in Chiba Prefecture were assessed as of the native or migrant type by using discriminant functions based on the tooth crown measurements. The Taishaku-Nagoshi, Karako-Kagi and two of three Bishamon remains were classified into the migrant type with high probabilities, while others were regarded as of the native type. From this finding, it is concluded that the genetic influence of migrants from the Asian Continent had at least expanded to the western part of the Kanto district by the middle phase of the Yayoi period.
