Outline of Final Research Achievements

This research addresses collection and analysis of kenchucho and related historical sources that served as tax collection ledgers. The research showed that there were changes in the registration method during the period from the early to late medieval age and that there were times when kenchu was intensively conducted, which led to a view concerning the correlation between kenchu and the changes in the estate system, a social system of the medieval age. Based on this view, a case study was conducted on estate remains in the former Bungo Province. The field study, conducted despite effects of the pandemic, and the use of the GIS to conceptualize the restoration method of land use conditions led to the acquisition of knowledge on tracing the land development process in the medieval age.

Academic Significance and Societal Importance of the Research Achievements

１：検注帳および関連史料の収集について。関連史料を網羅的に集めることで、検注の実施傾向を全国規模で捉えることができた。また、特定の時期に検注という土地調査が集中した要因を多角的に考察することができた。
２：旧豊後国の荘園遺跡でのケーススタディについて。1980年代から90年代にかけて、フィールドワークによる荘園研究は大幅に進展した。その一方で、現地景観の改変や過疎化の影響により、荘園故地に残された歴史情報は減少しつつある。GISによる土地利用状況の復原作業や、それをもとにした効率的な現地調査により、土地の来歴を探る汎用的な分析手法に到達しつつある。
