| Outline of Final Research Achievements |
I analyzed ten specimens of the extinct Japanese otter, which was planned at the beginning of this project, was carried out. As a result, the mitochondrial genome sequence was determined from several individuals. In this way, we obtained new data through this study. In addition, the living otter was found in Japan (Tsushima) during the project period, and we determined the mitochondrial genome sequence from the feces. Furthermore, to analyze the whole genome, I obtained shotgun sequence data from Eurasian, Asian small-clawed, and smooth-coated otters. These results will be submitted to an international journal in the future.

| Academic Significance and Societal Importance of the Research Achievements |
これまで日本列島の全域のニホンカワウソ個体群を対象に行ったDNAの研究は無かった。本研究の結果は明らかにされてこなかった日本列島の絶滅動物の自然史に新たな洞察を与える。さらに、本研究では当初の計画を発展させ全ゲノム解析を目指し、ニホンカワウソの近縁種からドラフトゲノム配列を得るためのデータを得て、ニホンカワウソの全ゲノム解析に挑戦し成果を出しつつある。ヒトや家畜以外の出土試料を用いた全ゲノム解析は世界でも多くなく意義はい大きい。
社会的にも注目されており、新聞や商業誌や公園で一般の方々が研究について目にする機会も多かった。日本の動物を理解することは一般の方々も求めていることが改めて認識できた。
