　View Summary

The Satsumon culture flourished throughout Hokkaido from about the 8th century to the 13th century A.D. before the emergence of the Ainu in recent times. Human skeletal remains of this period, however, have rarely been discovered. In 1966, the archaeological excavation team directed by Mr. S. Sawa of the Kushiro City Museum unearthed human skeletal remains from a grave pit of the Satsumon period at the Shimodanosawa site, Akkeshi-cho, eastern Hokkaido (Fig. 1). This skeletal material, consisting of the skull and parts of the post-cranial skeleton, was intensively examined for this study. The age and sex of these remains were judged from the morphological evidence to be an adult female. Although PENROSE's shape distance based on seven cranial measurements showed that the Shimodanosawa individual was slightly closer to the modem Tohoku Japanese than to the Hokkaido Ainu (Tables 1 and 3), the same distances based on 13 mesiodistal tooth-crown diameters showed that the Shimodanosawa was far closer to the Hokkaido Ainu than to the modern Japanese (Tables 2 and 4). Moreover, a likelihood ratio analysis of cranial nonmetric traits indicated that the Shimodanosawa remains were far more likely to have come from the Ainu population than from the modern Japanese population (Table 5). Noticeable, as to the nonmetric traits of the Shimodanosawa skull, was the occurrence of a well-defined third occipital condyle, which is known to be relatively frequent in the Ainu but extremely rare in the Japanese (Fig. 3). The shoveling of the upper central incisors was slight in the Shimodanosawa as it is in the Ainu and the Jomon. With regard to the post-cranial bones of the Shimodanosawa remains, such traits as the ponticulus posterior of the atlas, the narrow and deep intercondylar notch, as well as the pilastered shaft of the femur, and the transversely flattened shaft of the tibia are all believed to appear more frequently in the Ainu than in the Japanese population. Therefore, taking all the results obtained from this study into consideration, it can be concluded that the total morphological pattern of the Shimodanosawa skeletal remains is substantially not different from that of the Hokkaido Ainu of recent times.

　View Summary

A variant muscle originating from the 2nd and 3rd ribs and inserted into the medial border of the scapula was observed in a 67 year-old Japanese male cadaver at Sapporo Medical College, 1989. Since it is supplied by a twig of the dorsal scapular nerve, this variation is considered to belong to the rhomboid muscle group. This interpretation is also supported by the result of nerve fiber analysis of the dorsal scapular nerve. This variation seems to offer insights into the differentiating process of the rhomboid muscles from the muscular anlage destined to become the levator scapulae, rhomboid and anterior serratus muscles.

GEOGRAPHICAL VARIATION OF DENTAL CHARACTERISTICS IN THE JAPANESE OF THE PROTOHISTORIC KOFUN PERIOD

JOURNAL OF THE ANTHROPOLOGICAL SOCIETY OF NIPPON ( UNIV TOKYO )  98 ( 4 ) 439 - 449  1990.10  [Refereed]

　View Summary

Metrical and nonmetrical crown characteristics in the permanent dentition were investigated for seven protohistoric Kofun population samples from western and eastern Japan. The difference between the western and eastern Kofun series was significant in only one measurement in males, whereas in five measurements in females. The metrical analysis of female dentition indicated that the Kofun series of eastern Japan had a slight resemblance to the prehistoric Jomon series which were characterized by smaller overall crown size. However the overall crown sizes of the other Kofun series were larger than those of the Jomon and recent series of Japan. From these results, it was inferred that the Kofun series were closely tied to the Aeneolithic Yayoi series of immigrant type characterized by larger overall crown size, and that the genetic influence of the immigrants in eastern Japan was greater on males than on females during the Kofun period. On the other hand, the nonmetrical data showed close affinities between the recent Japanese series and both the Kofun series of western and eastern Japan, with a large gap between the Kofun and Jomon series. These results suggested that the distribution pattern of nonmetrical crown characteristics of the recent Japanese series had been constructed, at the latest, by the end of the Kofun period.

GEOGRAPHICAL VARIATION OF DENTAL MEASUREMENTS IN THE JOMON POPULATION

JOURNAL OF THE ANTHROPOLOGICAL SOCIETY OF NIPPON ( UNIV TOKYO )  97 ( 4 ) 493 - 512  1989.10  [Refereed]

　View Summary

Mesiodistal and buccolingual crown measurements were taken from the permanent tooth remains of the five Middle to Latest Jomon population samples from the Hokkaido, Tohoku, Kanto, Tokai and San'yo districts of Japan. The metrical data were compared with each other through multivariate statistical methods. The analysis of variance for these crown measurements suggested that most of the variables showing significant geographical difference were buccolingual diameters. The distance analysis based on the crown measurements revealed that the Hokkaido Jomon was isolated from the Jomon in Honshu, the main island of Japan. The Honshu Jomon groups were closely related to each other, although the male Tohoku Jomon was slightly closer to the Hokkaido Jomon. The principal factor analysis revealed that the overall dental proportion of the Hokkaido Jomon was different from those of the Honshu Jomon groups, and the Tohoku Jomon carried the smallest overall tooth size among the five Jomon population samples compared. From the comparisons with recent groups, it was indicated that 1)the diversity in dental morphology between the Hokkaido and Honshu Jomon was smaller than that between the recent Kanto Japanese and the Jomon as a whole; 2) the dentition of the Jomon population was characterized by relatively small canines, premolars and second molars as compared with thefirst molars; 3) these dental characteristics could also be seen in the dentition of the Ainu. These facts suggested a close affinity between the Ainu andJomon in the posterior tooth characteristics. However, with regard to the anterior teeth, both the relative and absolute dimensions of the incisors werelarger in the Jomon than in the Ainu. Thus, the size reduction of the incisors may have proceeded from the prehistoric Jomon to the recent Ainu.

Estimation of Stature of the Epi-Jomon Esan People in Hokkaido-A Preliminary Report

Memoirs of the National Science Museum ( National Science Museum )  21   221 - 227  1988

　View Summary

The stature of the Epi-Jomon Esan people in Hokkaido was estimated from the maximum length of the femur based on the regression formula of FUJII (1960). The results are given in Tables 1 and 2. Since the average stature was 159.5cm in the male and 150.0cm in the female, the Esan people seemed to be slightly taller than the Honshu Jomon (Figs. 1 and 2). Stature was relatively high during the Jomon and Epi-Jomon periods in Hokkaido and decreased slowly during the last 2,000 years. In Honshu, stature increased from the Jomon to the Yayoi or Kofun period and decreased gradually to recent times (Table 3,Fig. 3). Tibio-femoral indices were also calculated based on the maximum length of the femur and tibia (Tables 1 and 2). In Hokkaido, this index was stable for people from the Jomon to the recent Ainu period (Table 4,Fig. 4).
