From ancient time, it is well acknowledged fact among scholars that the Japanese race is composed of races of various kinds which are mixed with each other.
But however the Japanese may be composed of many races, the characteristic of constitutional anthropology which takes part in the formation does not disappear easily.
Therefore, it lead us to know the similarity of constitutional anthropology between both races to compare the result of studies on constitutional anthropology in some region with the result of that in the other region. For this purpose, the author carried out measuring of vital body for extremities, head face and body in regard to five-hundred numbers of the native in Yonezawa, prefecture Yamagata districts during the period of a month from April to May, 1957.
The present paper describes the Gist of the results of measuring of vital body which, have been studied in detail basing on the 24 heads of measuring rate and index. As the conditions of measuring, for the purpose above mentioned, those people are excluded from this measuring who are considered as the temporary residents of late, or man of abnormal constitutions at a glance. The measuring is limited to adult men ofnative-born from 20 to 45 years old who have settled down in this region during more over three generations ancestor to descendants. The author brings to light on the racial relations in accordance with the observations comparing the native of Yonezawa region. With natives of the other regions which had as much minutely been investigated. The author comes to concluded as follows: -
(1) The native of Yonezawa region belongs to middle class of height in comparison with a native of the other regions which Prof. Koya had measured. The medial rateis 159.10 cm and it belongs to little class of height classification made by Mr. Martin. As a whole tendency, they are similar to Hokkaido-Ainu, natives of Hyuga and Tcjkaii districts.
(2) On the comparative-length of upper-extremities, those who belong to middle arm: according to Iwanovski's classification occupy 55.60%, that is half the number.
(3) The maximum length of head is 185.46 0.21 mm. The maximum breadth of head is 153.02 0.20 mm and the ratio, that is, the index of length-breadth of head, is 81.27-F-0.11mm. Namely, the index indicate the middle grade of short head and it is similar to natives of Sagami-heiya, Shinshu-Azumi, and Hida-districts.
(4) The breadth of zygomatic arch is 144.15 0.18 mm. The index of the breadth, of zygomatic arch is 79.03 - 0.14. In accordance with the face classification, it belongs to the middle type which is the most popular in Japanese people.
(5) The morphological face index is 85.47 0.24mm. The rate is similar to nativesof Yamato district, Hokkaido-Ainu, and Ettyu d: stricts. On the classification of facial type in accordance with this index; the middle type. occupies half the number and next to it, the nallow type occupies a good number.
(6) On the mean of type difference, when compared it with the rate of the other: districts, it become clear that the native of Yonezawa region shows the racial similarity to natives of Okunoto, Koriyama, north part of Sinshu, Hida, Kaga mountain region. (mean of type difference is less than 8.0mm)
(7) In the case that mean of type difference is more than 15.0 mm. The south-Korean and Hokkaido-Ainu show large disparity at the racial similarity.
