| Outline of Final Research Achievements |
The purpose of this research is to develop methods of estimating the area of origin of unidentified remains by elemental analysis combining isotope ratio analysis and concentration analysis. We performed various elemental analyses using clinically extracted teeth collected from patients in various parts of Japan, Papua New Guinea and the Philippines as samples, and based on them, we examined the estimation of the region of origin.
As a result, although the diversity that seems to reflect the difference in climate, geology and food habits has been observed in humans, due to the limited number of samples, analysis items, and the number of areas at present, we have not achieved success in the detailed estimation of the area of origin yet.
However, it has been shown to be effective for separating the locals and migrants in a particular locality, as in the case of recovery of Japanese and American war dead from excavated remains.

| Academic Significance and Societal Importance of the Research Achievements |
現在、厚労省が実施している先の大戦における日本人戦没者の遺骨収容事業では、地元住民、米国戦没者及び日本人戦没者の遺骨混同が、大きな社会問題、国際問題となっており、事業進捗の大きな障壁となっており、その対応が急務となっている。本研究の成果は、この問題への解決策を提示できるものとして期待されている。
