In recent years, cooperation between local governments and residents has become essential for managing abandoned railway sites in rural areas facing depopulation and limited resources. Focusing on the Nagano Dentetsu Yashiro Line, this study aims to clarify local government maintenance strategies and the actual patterns of provisional use by residents. Through field surveys and interviews, it reveals how these uses are shaped by surrounding land use and local conditions, offering insights into current challenges and the potential for resident involvement in future site management.
