Recently, there has been a surge in experiment-based projects to improve the effectiveness of projects targeting regional challenges. Many governmental departments have issued open calls for “Social Innovation Labs,” initiating preliminary projects before the main project or conducting innovative projects at the project’s outset to boost effectiveness. The Ministry of Maritime Affairs and Fisheries’ New Project for Revitalizing Fishing Villages introduced and implemented the “Social Innovation Program” as a means to assess project feasibility through trial and error before providing large-scale state subsidies. However, there remains a lack of detailed concepts or execution methods for these experimental activities, often referred to as social innovation, living labs, and life experiments. Consequently, local governments encounter difficulties in project implementation, leading to a growing demand for specific definitions of concepts and execution guidelines. This study, therefore, defined various experimental activities as social innovation experiments and aimed to explore implementation plans for social innovation experiments by examining the concepts, roles, and implementation processes involved in social innovation experiments designed to test the feasibility of regional revitalization policy projects.
