日本刀の学術的価値を明確にするためには、その表面形態解析が不可欠である。これまで表面形態解析は刀剣研究者に依存しており、刀剣研究者がいう日本刀表面形態の特徴を刀剣愛好家が視覚的に理解することは困難であった。本研究では株式会社リコーと、従来の日本刀鑑識法を踏襲した多色拡散撮像装置を共同開発し、日本刀100口のデジタル画像を作成した。その結果を解析し、日本刀五大流派の地鉄の特徴をまとめた資料集を作成した。併せて、研究成果の一部を平成23年度「名物刀剣」展、平成25年度「清麿」展で公開し、日本刀の地鉄の美とその変遷を一般に認識させるよう努めた。
 In order to clarify the academic value of Japanese swords, the analysis of their surface morphology should be essential, which has been solely depending on the observations by the Japanese swords researchers. Therefore, it has been difficult for the Japanese sword fans to visually understand its surface morphology characteristics only by the researcher's descriptions.  In this research, digital images of 100 swords were taken by the polychromatic diffuse reflection image capturing device developed in conjunction with Ricoh Co.,Ltd. The obtained results were analyzed and the surface morphology characteristics of the swords belonging to five sword schools in Japan were summarized in a source book. In addition, a part of the results were introduced in special exhibitions of "Meibutsu Treasured Japanese Swords" in 2011 and "Kiyomaro" in 2013. A great effort has been also made for sword fans to understand the beauty in surface morphology of the Japanese swords through these activities.
