The principal objective of this study is to analyze welfare effects of Japan's rice import quota focusing on the simultaneous buy and sell (SBS) of the rice importation minimum access (MA) policy. Based on the utility function specified in this study, the constructed model is adopted to measure consumption patterns through estimating elasticity of substitution between imported rice and Japan's domestic rice, and consumers' preference parameters for different kinds of rice. The results showed that Japanese households prefer domestic rice to the imported rice. Besides, three scenarios of adjusting rice quota volumes were carried out to examine the changes in consumer prices of imported rice and Japanese consumers' welfares. The results revealed that tariffequivalents of the SBS import quota almost doubled the scale of the mark-up, and the intervention by the Ministry of Agriculture of Japan did cause non-tariffbarriers to trade (NTBs). Finally, if the SBS rice quota quantity was fixed at or larger than 180 thousand tons every fiscal year, the consumer prices of imported rice in Japan's market would decrease to be less than the prices of Japan's domestic rice, and therefore the imported rice would have more price advantages in this scenario.
