Title:"Differentials of Yayoi immigration to Japan as derived from dental metrics."
Abstract:"A major influx of new people, today termed Yayoi, migrated from the East Asian continent into the Japanese archipelago during the Aeneolithic and Protohistoric periods and interbred with the preexisting jomon people. This study classifies ancient and more modern Japanese into natives or immigrants using discriminant analysis based on dental measurements in order to reconstruct the initial impact of the immigrants and the temporal and geographical differentials of mixture with the preexisting people. The results suggest that the earliest immigrants diffused into central Japan, including the Kanto region. The proportion of immigrant origin in the protohistoric Kofun was less in eastern Japan (72%) as compared to western Japan (81%-90%). The proportion of the immigrants in the Kanto District decreased during the medieval period (63%) and increased again in the early modern Edo and later modern times (75%), which might indicate that the gene flow still was occurring from west to east even in these times. Assuming the estimated proportions of either group reflect the intermixture ratio, the recent Japanese people may be regarded as hybrid of the native and immigrant groups with the following approximate ratios: 1:3 for the Kanto Japanese, 2:3 for the Ryukyu Islanders and 7:3 for the Hokkaido Ainu. These estimations support the dual structure model, formed by Hanihara (1991) for explaining the population history of Japan.."

Differentials of Yayoi immigration to Japan as derived from dental metrics
A major influx of new people, today termed Yayoi, migrated from the East Asian continent into the Japanese archipelago during the Aeneolithic and Protohistoric periods and interbred with the preexisting jomon people. This study classifies ancient and more modern Japanese into natives or immigrants using discriminant analysis based on dental measurements in order to reconstruct the initial impact of the immigrants and the temporal and geographical differentials of mixture with the preexisting people. The results suggest that the earliest immigrants diffused into central Japan, including the Kanto region. The proportion of immigrant origin in the protohistoric Kofun was less in eastern Japan (72%) as compared to western Japan (81%-90%). The proportion of the immigrants in the Kanto District decreased during the medieval period (63%) and increased again in the early modern Edo and later modern times (75%), which might indicate that the gene flow still was occurring from west to east even in these times. Assuming the estimated proportions of either group reflect the intermixture ratio, the recent Japanese people may be regarded as hybrid of the native and immigrant groups with the following approximate ratios: 1:3 for the Kanto Japanese, 2:3 for the Ryukyu Islanders and 7:3 for the Hokkaido Ainu.
