Optimal Immigration Policy for Japan

Project Leader/Sub-Leader

The National Institute of Population and Social Security Research estimates the population of Japan to be 80 million in 2060 and 30 million in 2110 and the working-age population (15 to 64) to comprise 49% and 45%, respectively. These numbers show that Japan will face the danger of a serious labor force shortage. To address this situation, a rise in the fertility rate no longer seems effective, and Japan will have to rely on immigration. In this project, we investigate immigration policies of foreign countries and their effectiveness, and survey academic research on this field. As a result, a proposal of an optimal immigration policy for Japan in the future is expected.
