| Outline of Final Research Achievements |
This study clarified a strong selective relationship between the administration and kozo paper made of kazinoki in the Ryukyu Kingdom in the early modern period. To this end, this study examined the original Ryukyu Okoku Hyojosho Monjo (supreme court documents of the Ryukyu Kingdom) and ancient documents as well as historical records of the Sakishima region in the early modern period from the perspective of writing paper. In early modern Ryukyu (Okinawa at present), kozo paper was called kajigami or momotagami. Although the use of paper expanded and its demand increased, fillers such as rice glue were not used in its manufacture. Therefore, the contexture (quality) of the paper was presumed to be low. When we surveyed the Sakishima region, we examined the oldest documents of Tsutomegaki in Miyakojima City. Through microscopical analysis, we discovered that the paper used for Tsutomegaki was the same as that used for the genealogical table of a family (namely, kozo paper).

古文書・古典籍については、まず所在調査により散逸亡失が防がれ保存状態の向上が図られる。その後、必要に応じて修復作業が行われ、影印や翻刻出版により内容の精読が可能となり、史資料として活用されていく。修復過程では、冊子体の資料も一丁ごとに分解されるので、紙の厚さ、擱筆などの所見を調査票に記録し、料紙の原料についても顕微鏡分析を行い画像データを集積できる。戦禍を免れた沖縄関係の希少な資料は、一紙文書よりも関連書類を綴じた一件書類が多い。この種の資料に対して修復と連携した総合的な研究を行い、所在調査・修復・料紙分析と一貫した研究の重要性について関係者の理解を広げることに最大の学術的社会的な意義がある。
