Metric and nonmetic traits data were obtained from the cranial and dental series of the Nakazuma Jomon people and compared with those of other Jomon samples. Significant differences were not found in most of the metric and nonmetric traits, suggesting that the cranial and dental morphology of the Nakazuma Jomon people are similar to those normally found in the other Jomon samples. Some of the differences observed in a few traits were considered to be caused by the genetic drift within this population unit probably consisting of close kinship groups.
