In 2017，the trend of aging population with fewer children in Japan has become even more severe，which affects all aspects of Japan’s society. Marriage rate falls，the size of family shrinks and one-person household and households of only the couple increase. Parenting and kindergarten-entrance also becomes more narrow. The storage of labor force become even serious. The impoverished population increases while the middle class population reduces. The trend of population concentration in Tokyo Metropolitan Circle continues to intensify. In that context，Japanese government launched the policy of “Super Smart Society—Society 5.0” in June of 2017，attempting to applying new technological achievements of the fourth industrial revolution to solving the social problems brought by the aging population with fewer children. Japanese government also implements a series of policies，including using big data to create a new medical care System，promoting work-style reforms and limiting working time and carrying out “equal pay for equal work” to reduce the gap between the treatment of regular and non-regular workers. It also works to promote the regional economic revitalization，improve the talents investment and reforming the university education system in order to alleviate the trend of population concentration in Tokyo Metropolitan Circle.
