With the development of world economy and increasing life expectancy of the countries around the world, the pressure of the world’s population aging is more and more obvious. The aging of the population structure, in turn, will influence the development of a country’s economy. At present, the world’s population aging mainly concentrated in the economically developed countries and regions. Japan is one of countries which are affected by the population aging. Japan’s economic growth can’t ignore the factor that the aging is more and more important. The population aging gives a shock to labor supply, consumption, savings, etc. In this paper, we study the influence of population aging on economic growth of Japan. We analyze the effects of population aging on economic growth paths and do empirical research on the analysis of the effect of population aging on Japan’s economic growth. The conclusion of the empirical research and measures which are taken by Japan can give China certain enlightenment. At present, China has entered into the aging society. We must face the problem of "the aging before being rich". The conclusion of the empirical research on the impact of population aging on Japan’s economic growth is worth reflecting in China.The text is divided into four parts:The first part:From the perspective of international comparison, with a large amount of data, we compare population aging situation between Japan and other major developed countries. We put emphasis on analyzing the development status, trends, severity of the population aging of Japan.The second part:The aging of population is elaborated in four parts. We mainly analyze from the aspects of the labor supply (including enterprise employment system), consumption, savings and the adjustment of the industrial structure.The third part:We analyze the impact of the population aging on Japan’s economic growth by the empirical research. It is found that elderly dependency ratio and Japan’s economic growth are positively related. The elder population growth and Japan’s economic growth are negatively related. The increase of labor and capital investment can promote Japan’s economic growth.The fourth part:The analysis, conclusion and measures of Japan’s population aging have enlightened China’s problem of aging population. Under the condition of China’s aging population, this paper gives five suggestions:(1) the full development of the existing "demographic dividend";(2) the exploit of the aging industry;(3) the gradual adjustment of retirement policy;(4) the gradual adjustment of the population policy;(5) perfecting the social security of the old.
