This study aimed to investigate the relationship between consciousness of contribution to regional agriculture and regional activity, using the results of an Internet survey focused on agricultural corporations. Three factors emerged from the analysis: consciousness of contribution to (1) regional agriculture, (2) regional economy, and (3) agricultural land problems in the region. The results of the classification and regression trees analysis showed that consciousness of contribution was influenced by three factors. First, event holding (e.g., farming experience) was an important factor in the consciousness of contribution to regional agriculture. Second, the acceptance of inspections and contract production with local farmers was an important factor in the consciousness of contribution to the regional economy. Finally, undertaking farmland for farmers without heirs was an important factor in the consciousness of contribution to land problems.
