Outline of Final Research Achievements

Basic research on Kamakura shogunate laws, such as the Goseibai-Shikimoku and additional laws, peaked in 1955 with the publication of "Historiography of Medieval Laws, Volume I: Kamakura Shogunate Laws" (Iwanami Shoten), edited by Shinichi Sato and Yoshisuke Ikeuchi. In light of the development of catalogs and digital archives, this study aimed to revisit the Kamakura Shogunate Laws and restart the study of Shogunate Laws through a bibliographic and bibliographic examination. With the research funds, we were able to visit libraries across Japan and find manuscripts that had not been used in previous studies, thereby deepening our research.

Academic Significance and Societal Importance of the Research Achievements

北条泰時が制定させたことで有名な御成敗式目の原本は残っておらず、さまざまな写本を組み合わせて原態を復元する必要がある。また、御成敗式目以後の幕府法（追加法）を集めた法令集も、写本ごとの出入りが非常に多く、基礎的な検討が不足していた。また御成敗式目の注釈書は難解な記述が多く、本文の読解が進んでいなかった。本研究では全国各地の写本を調査し、従来知られていなかった鎌倉幕府法を発掘したり、写本間の系統を考える素材となる記述を発見することができた。
