This study aims to clarify the rationality and development possibility of feed rice production in the area with the low rice price and low yield. The main outcomes are as follows. As the rice prices are low in optional rice yield, feed rice production tends to become rational more. Second, as the rice yields are low in optional rice price, feed rice production tends to become rational more. These two tendencies indicate development possibility of feed rice production in the rural area where rice production declines.
