The aging society is a double-edged sword of sharing economy. On the one hand, according to Nielsen and other research institutions, the acceptance of sharing economy by the elderly is far lower than that of the young, which is a slow and hot group of sharing economy. On the other hand, with the passage of time and the accumulation of wealth, the elderly are rich in physical assets (including houses, cars, money, etc.) and are generally under used, which is bound to be activated through sharing economy. Therefore, the elderly are a large group that can not be ignored in sharing economy. Therefore, the British government points out in the report of sharing economy that the elderly should be popularized online, Reduce barriers to participation in the sharing economy.

Japan is a typical aging society, but with the rapid growth of Japan's tourism industry and the deregulation of Financial Sharing by the government, the acceptance and demand of Japanese people for the sharing economy is also increasing, so the sharing economy is also starting rapidly.
