日本史史料の科学研究: オープンサイエンスと国際化の推進に向けて



Science of Japanese Historical Materials: Toward Open Science and Internationalisation

Since Katsumi Kuroita proposed palaeography as an adjunct to early modern Japanese history, palaeography has progressed in terms of sourcing various historical information, not limited to textual information, from historical materials. Among these developments, studies on papers used as historical materials have focused on documents from the ancient and medieval periods. Specifically, such research has identified and classified types of papers by investigating the materials and traces involved in the paper-making process and exploring the history of paper materials from manufacture to utilization. Observation methods for historical materials regarded as objects are of growing interest in the fields of natural science, paper-making science, and the restoration of cultural properties, in addition to history, and many surveys are being conducted using microscopes to observe and analyse the structure of papers used as historical materials.

In recent years, the Historiographical Institute (HI) of the University of Tokyo has developed a microscopic image management tool and a morphological historical material data management system and has aimed to establish a method for analysing historical materials by integrating various related fields, such as archaeology and cultural heritage science, as well as material structure analysis, botany and genome analysis, and data science methods, targeting the quality and constituent materials of historical paper-based materials. As part of this activity, HI conducts non-destructive surveys and analyses of HI’s collection of “Documents of the Shimazu Family” and historical materials in the Matsunoo Taisha Shrine collection in conjunction with materials from other cooperating institutions. HI is also attempting to classify and analyse research data acquired using data science and data-driven science, such as historical material information and scientific analysis data pertaining to paper materials. This presentation introduces these activities as a new research perspective on Japanese historical materials in the open science era.
