Outline of Final Research Achievements

In this study, I aimed to comprehensively understand and elucidate the ideological and cultural exchanges between Buddhist monks of Japan in the mid- to late Heian period, specifically the regency and insei (cloister government) periods, and the Buddhist communities of Wu-Yue and Northern Song dynasties, centered around the Zhejiang region in China, as well as the external perceptions of the Japanese literati aristocrats.
In China, due to the turbulence at the end of the Tang dynasty and the Five Dynasties period, temples fell into ruin, prompting an active search for the Buddhist scriptures in Japan. Amidst this mutual exchange, it became prominent in the Japanese Buddhist community to resolve doctrinal questions and to send books to China seeking evaluation. By attempting to uncover a new essence of Japanese thought that had not been previously identified, this study has achieved certain results.

Academic Significance and Societal Importance of the Research Achievements

本研究期間の前半は新型コロナ禍の影響を受け、特に国際交流が停滞したが、期限内に論文・註釈7本を執筆し、国内外での講演・研究発表20回（うち本研究共催国際研究集会3回）を行い、社会に向けて成果を発信することができた。また本研究は、中国の国家社会科学基金重点項目「古代中日佛教外交研究」（江静代表）と連動させ、グローバルな視点から研究を推進することができた。研究課題の一つである、永観『往生拾因』と撰者未詳の『心性罪福因縁集』について出典調査・訳註を行い、ともに3年以内に訳註を出版する予定である。また『聖徳太子伝暦』の本文テクストも、2年以内に刊行する準備を進めている。
