Abstract: According to the methods of Japanese scholar Yukio Dodo the present author explored the incidence of the supraorbital foramen and the hypoglossal canal bridging in many human sheletal assemblages of China belonging to Neolithic, Bronze age, and Iron age and its bearing in the aspect of Japa- nese origins. The results are presented as follows: Great similarity existed in hereditary features of hu- man skulls of the Neolithic Age, the Bronze Age, the Iron Age and modern times in the Yellow River valley of China. Close resemblance is shown between, the people in the Yellow River valley of China and the people of Japanese.The populations studied in this article are similar to those of modern groups and immigrant series of Japan in possessing high frequency of occurrence of supraorbital foramen and low frequency of occurrence of hypoglossal canal bridging. The hometown of Japanese immigrant series may be in the Yellow River of China especially in the area along the Mid-lower Yellow River. Probably the Japanese immigrant series came directly from the coastal areas of China or they crossed the sea and passed the Korea Peninsula, after that they first settled in the areas of North kyushu-Yamagu-chi of Japan and then gradually spreaded to east and north, from west.
