Abstract
This study examines the promotion of sake-brewing rice production, which has been developed independently. A survey of farmers and a sake-brewing company in Kochi Prefecture was conducted to identify the factors contributing to this situation. The survey revealed that the production infrastructure is well-established, and there is a sufficient price differential compared to edible rice. Production is encouraged because of the benefits for the producers. In such cases, fostering a stronger relationship with the sake-brewing company facilitates reaching a consensus on quality improvement and supply-demand adjustments.
