“Japan is aging rapidly, those over 65 already constituted 27.7% of the total population in 2017. This figure is the highest in the world and is projected to grow continuously up to 38.4% in 2065 (1). However, population aging is a result of remarkable success in health improvement and economic development in a country or region, and a similar trend is becoming visible globally, particularly in Asia. Hence, Japan is only a front runner of a future aging world, and her experience will be beneficial for countries that are to follow. However, the demographic impact of aging is more complicated than just a growing number of senior citizens. Another side of the coin is that decline in birthrate to below the death rate results in population decrease, and especially reduction of the young workforce.”
