This study examines the role of volunteers in the formation of social initiatives that utilize local resources. Previous research on volunteering has typically explained participation in terms of altruistic motives and a desire to contribute to society. However, this study focuses on intellectual curiosity—specifically, an interest in observing on-site situations and analyzing problem structures, as a factor that supports the continuity of volunteer activities.The study analyzes a local resource project that utilizes camellia leaves naturally growing on a remote island in Miyagi Prefecture, Japan. Using qualitative analysis, we examine the activities of a central practitioner, referred to as Practitioner A. Practitioner A plays a bridging role by connecting multiple actors, including local residents, companies, welfare facilities, tourism stakeholders, and researchers. This study conceptualizes such practitioners as “analytical volunteers.” Analytical volunteers are participants who are motivated not only by altruistic intentions but also by an intrinsic interest in observing real-world situations and constructing activities through problem analysis.The case analysis reveals that while the camellia project has succeeded in forming a network among diverse actors, it has not yet achieved stable commercialization. This stage is interpreted as the “growing pains” of social innovation in local communities.This study contributes to volunteer research by highlighting the presence of participants motivated by analytical thinking and by demonstrating the importance of network intermediaries in the formation of regional innovation processes.
