The Enasan-Sanageyamakita fault zone is one of the segments of the Byobuyama-Enasan and Sanageyama fault zone although the Enasan fault and the Sanageyamakita fault have different type of fault movement. We conducted surveys on the Enasan fault in 2021FY and on the Sanageyamakita fault in 2022FY, respectively. We will discuss the direction of fault movement on those faults in this presentation. This survey was a part of the Comprehensive Research Project for the Enasan-Sanageyamakita Fault Zone by MEXT.
