In recent years, there has been a shortage of short-term employment labor in agriculture. As short-term employment labor is not able to make a living from such agricultural work-based income, people with unstable employment outside agriculture have been hired as short-term employment labors. This has led to the shortages in short-term agricultural labor supply. For this reason, it is necessary to focus on University Student Farm-support Volunteers as human resources that can be supplied for reasons other than income. In order to increase the number of university students who participate in Farm-support Volunteers activities, it is necessary to establish conditions and systems for accepting university students. In order to clarify the various conditions necessary to promote the participation of university students in such volunteerism, this paper outlines analysis of the factors for volunteer participation from the existing studies, including case studies of acceptance conditions, while also reporting on a questionnaire survey on the target cases. The following three system conditions were identified. First is acceptance conditions that correspond to the strong motivation of university students to participate in volunteer activities. Second is well-balanced incentives for student volunteers by combining psychological rewards, monetary rewards, and the type of activity desired by the host farmer. Third is a volunteer work environment that matches and responds to the unique characteristics of university students.
