Abstract
A regional food security policy is intended to increase the regional rate of self-sufficiency in food supplies. This study uses choice experiments to evaluate such policies. Our main aim is to determine whether food security policies at a regional level can substitute for a national food security policy. Our analysis shows that this can occur to some extent. However, the analysis also reveals that when the national food self-sufficiency rate is beyond 70 percent, citizens accord almost no value to increasing the regional rate. Currently, Japan's national rate of self-sufficiency in food supplies is approximately 40 percent; therefore, raising the regional rate could be used to compensate for the low national rate.
