An aging society is a society in which the elderly population aged 65 or older accounts for 7% of the total population. On the other hand, if the proportion of the elderly population exceeds 14%, it is defined as an aged society, and if it is more than 20%, it is defined as a super-aged society. The aging factor is the decline in birth and mortality, and longevity is also a human wish in the sense that a country with a long life expectancy is an advanced country and symbolizes a peaceful and stable society. On the other hand, socioeconomic measures to respond to diseases, poverty, solitude, and unemployment that follow the aging society are the immediate tasks of an aging society. Although it is an aging trend worldwide, Japan's aging population is the fastest. This paper will look at the problems of an aging society and Japan's aging status and countermeasures.
