縄文・アイヌ集団と太平洋諸集団の系統関係

Biological relationships between the Jomon-Ainu and Pacific population groups were investigated through statistical analyses of the following 5 cranial indices: length-breadth, length-height, upper facial (after Kollmann), orbital and nasal indices. Data sets analyzed were consisted of 25 representative populations from Japan, Polynesia, Micronesia, Melanesia, and East Asia. The results supported a diffusion model supposed by many anthropologists as well cluster model proposed by Brace and colleagues and Katayama\u27s similar hypothesis. The former 2 models stress the migration of both Pacific and Jomon-Ainu groups from somewhere in Southeast Asia, while the latter emphasizes a direct lineage from the Jomonese to the Pacific group. It was also confirmed that Java may have been part of a diffusion center from where the migration to the Pacific and Pacific-rim areas had taken place

日本における自然人類学研究の現状

The trends in physical anthropology in Japan have largely changed through the introduction of new methodologies such as molecular genetics and multivariate statistics in the 1960s. The development of ecology and primatology brought another new wave into the field of physical anthropology. This paper reviews briefly general trends in research in physical anthropology now on-going in Japan. Microevolutionary studies of the Japanese and neighboring populations which have a long history in Japan will be reviewed in more detail

エミシ、エゾ、アイヌ : その人類学的考察

Relationships among Emishi and Ezo of ancient through the medieval ages, and Ainu of recent through modern ages are discussed on rge basis of statistical analysis of cranial measurements. The discussion is mainly focused on the long-disputed question of whether the ancient Emishi were derived from Ainu or from non-Ainu Japanese. The study was carried out by analyzing affinities between inhabitants in the Tohoku district and those in Hokkaido throughout the periods from the Neolithic Jomon to modern ages. The results show that both populations were derived from the Jomon populations and gradually separated from each other after the Yayoi age which was the final stage of the Neolithic in Japan. The separation seems to have proceeded for as long as about 1,000 years and, as a result, non-Ainu Japanese changed to show quite different characteristics from Ainu, both physically and culturally, by the 13th century. The causes of the separation may be attributed to the influence of migrants from the Asian Continent after the Yayoi age. It is quite likely, therefore, that Emishi in ancient times were populations in the early stage of separation. In other words, they were neither Ainu nor non-Ainu Japanese of modern types, so the question of whether Emishi were Ainu or non-Ainu Japanese becomes meaningless

A review of recent case reports of cenesthopathy in Japan

Idiopathic abnormal bodily sensations, or cenesthesic symptoms, are exhibited in a wide variety of mental illnesses. In Japan, patients with abnormal bodily sensations are often diagnosed with cenesthopathy. This study reviewed recent case reports of cenesthopathy. Of the 100 identified cases, young patients were more commonly men with predominant bodily cenesthesic symptoms, while older patients (40 years) were more commonly women with cenesthesic symptoms restricted to the oral cavity (oral cenesthopathy).ArticlePSYCHOGERIATRICS. 13(3):196-198 (2013)journal articl
