Outline of Final Research Achievements

This study explores the legal theories specific to commercial insurance contracts covering large-scale risks in light of insurance law. It investigated domestic and international practices and theories, culminating in the publication of the specialized book "Theory and Practice of Commercial Property Insurance" (2021). Furthermore, through comparative law analysis, the research delved into key areas of commercialinsurance contracts, such as reinsurance contract principles, disclosure obligations, subrogation, D&O insurance, cybersecurity, commercial earthquake insurance, interpretation of exemption clauses, the legal significance of exemptions, and reinsurance case studies. The study examined the essential characteristics of commercialinsurance,proposing new research directions that explore contract principles based on risk.The outcomes include one book, fourteen papers in Japanese and English, nine research reports across five countries, and contributions to collaborative writings.

Academic Significance and Societal Importance of the Research Achievements

わが国の保険法研究は個人向け保険契約を想定したものが多く、企業保険契約の研究は海上保険を除くと蓄積が少ない。本研究で発表した図書や論文は、企業保険契約の実務や理論を示す研究として学術面のみならず実務界からも高い評価を得ることができた。また、本研究では、企業損害保険契約の個別論点の研究に加え、その本質的特徴についても考察し、契約者の属性(企業か個人か)でなく対象とするリスクの特性(予測性の高低)に基づく契約理論を構築すべきとの仮説を示した。本仮説は、保険法のみならず、保険学、保険行政まで影響を与えうる大きな提言で、すでに一定の反響が得られており、今後の新たな研究の方向性を示したといえる。
