This feature makes Japan different from other advanced countries, indicating that Japan is not a friendly society for working women raising children. Efforts to improve the environment for women, such that they can handle both a career and raising children, are meaningful not only for economic growth but for the society.
Moreover, we should not overlook the fact that Japanese people are living longer and the number of the elderly blessed with good health and physical strength is increasing. There is research showing that the physical conditions of elderly people have improved and those who can work vigorously have increased.
