Outline of Research at the Start

本研究は、研究代表者らがこれまで確立してきた放射光X線を用いた鉄鋼文化財の非破壊分析技術を日本刀の作刀技法の解明のために応用し、刀剣の専門家や博物館、放射光分析の専門家他と学際的な研究グループを組織し、作者や流派、時代に焦点を絞り5年間で120振を超える価値ある日本刀を体系的に分析することで最終的に日本刀の黄金時代と言われる鎌倉中期の作刀技術を解明する。

Outline of Final Research Achievements

In the first year of this study, we analyzed Japanese swords that have distinctive characteristics and in the second year we analyzed Japanese swords from the Muromachi period onward using synchrotron X-ray CT. From the third year to the final year of the project, Japanese swords from various periods were investigated. A systematic nondestructive analysis of more than 120 swords was achieved, which was the goal of this project. We analyzed precious Japanese swords from the Soshu (Masamune), Yamashiro (Awataguchi and Rai schools), and Bizen (Ichimonji school) regions during the mid Kamakura period, which is considered the golden age of Japanese swords. We were able to verify differences in the internal structure and production techniques of Japanese swords by period, region, and artist through interdisciplinary research members including sword history, conservation science, synchrotron radiation analysis, and swordsmith.

Academic Significance and Societal Importance of the Research Achievements

本研究は、最新の放射光X線CT技術を日本刀の体系的研究に応用し、非破壊で日本刀の鋼中の数十~数百ミクロンサイズの非金属介在物を高分解能で観察することで、秘伝とされてきた日本刀の具体的な作刀技術を解明することを目的としている。世界的にもその機能性や美しさが評価されている日本の代表的な文化財である日本刀を5年間で120振り以上分析し体系的な調査を行う本研究は、非常に学術的意義と独自性に富む研究である。近年日本刀に対する社会的な興味・関心が高まっており、経験に基づき行われてきた日本の作刀技術の解明および保存・伝承につながる本研究の意義は大きい。
