The origins and affinities of Japanese were analysed by means of cluster analysis using nine cranial measurements which were statistically selected as those representing a large proportion of the variance. As a result, the following hypotheses are proposed: Japanese are basically descendants of Jomon people, a fairly large amount of admixture between migrants from the Korean Peninsula and Jomon people took place during the Yayoi and protohistoric ages, particularly in western Japan, the migrants were close to north Asians in cranial morphology, Ainu and Ryukyus (Okinawan people) seem to be direct descendants of Jomon people without any or with very little influence of the migrants and geographical variations in modern Japanese quite likely are the result of differences in the magnitude of admixture.
通过聚类分析，利用九项颅骨测量数据对日本人的起源和亲缘关系进行了分析。这些测量数据经统计筛选后，被认为能代表大部分的变异情况。结果提出了以下假设：日本人基本上是绳文人的后裔，在弥生时代和原史时代，来自朝鲜半岛的移民与绳文人之间发生了大量的混合，特别是在日本西部，这些移民在颅骨形态上与北亚人相近，阿伊努人和琉球人（冲绳人）似乎是绳文人的直接后裔，几乎没有或很少受到移民的影响，现代日本人的地理差异很可能是混合程度不同的结果。
