| Outline of Final Research Achievements |
This study uses historical materials related to the Akana clan, a mountain lord in medieval Izumo, to examine the characteristics of their form of existence and behavior, while paying attention to the position of military lords in the power order of the late medieval period. The main research subjects are the Akana clan of Izumo and their soryo family, the Sawa clan of Iwami.The former as a retainer of the Shugo Kyogoku clan, and the latter as a servant of the Muromachi shogunate, how did they respond to changing social conditions, we investigated how they tried to survive.
In order to deepen our analysis, we also collected historical materials regarding the Shimotsuke Motegi clan, the Bingo Innoshima Murakami clan, the Aki Takehara Kobayakawa clan, the Iwami Masuda clan, and the Chikuzen Aso clan, and attempted to compare them with the Akana clan and the Sawa clan. We also analyzed the tansen collection system and chigyo system in the Ouchi clan's bunkoku.

「赤穴郡連置文」は、室町から戦国への移行期における武家領主のあり方を考える上で希有な史料であり、その作成事情を分析する中で、作成目的や背後関係を浮かび上がらせることができた。置文の内容分析からは、武家領主の存在形態や行動様式が一様なものでなく、幕府―守護系列を基軸とする国郡支配関係と、惣領家との間で取り結ばれる惣庶関係のはざまで微妙に揺れ動く姿を、権力状況の変動と結びつけて具体的に描き出した。
武家領主の権力編成と役負担のあり方について、広く目配りして論述したのも重要な研究成果である。大内氏分国の段銭収取システムに関する研究とともに、中世後期の役負担体系のあり方を問い直す意義をもつと言える。
