Outline of Final Research Achievements

In this study, we examined the actual situation of maintenance from ancient times to modern times by deciphering old documents and collecting and accumulating past repair information. Specifically, for the former, we collected information on the repair of temples centered on Nanto Shichidaiji Temple. Regarding the latter, we held a study group on the past repair history revealed by the current dismantling and repair of national treasures and important cultural properties, and analyzed the repair of Taima-dera Temple.Through these efforts, it became clear that repair methods and philosophies existed that had diverse values different from those of modern repair.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果により、前近代の多様かつ継続的なメンテナンスに関する状況が明らかになった。特に修理に対する意識が平安初期に強まって以降、必ずしも修理は定期的になされたわけではなく、またその手法も修理時の時代性を強く反映したことが見えてきた。これらの成果により、近代以降の文化財保護制度の下での厳密な修理に対し、応急的な修理方法や時代性に応じた多様な修理方法の可能性を示すことができた。
