Abstract
Based on materials collected from reliable sources covering the whole parts of Japan, the cephalic type of Japanese adults of both sexes in age groups 20-60 as of 1950-1952 was studied.
The result is summarized here: 1. Head length is longest in remote villages and shortest in towns ; the opposite is the case with head breadth.
Length-width index:
Towps>Rural Village>Mountainous Village>Fishing Village.
Head height is generally greater in towns than in villages.
2. Inhabitants of Kinki Area including Kyoto and Osaka are of the town-people type, while Tohoku, Hokuriku and Kyushu people are comparatively long- and low-headed. Peoples of intermediately situated Chugoku, Shikoku and Kanto Areas are also intermediate in cephalic indices.
3. Tsushima islanders are peculiar in the sense that they conform with Kinki people, although the island, in Korean channel, is located near Kyushu. This suggests difference of their discendance.
4. The author's result points to a close relationship of the cephalic indices and head shape with cultural environment and intellectual faculty, broad- and high-headedness being connected with civilization.
