One reason for the increase in deaths attributed to old age is the aging of Japan’s population: people aged over 80 now make up 10% of the total. Since the introduction of the long-term care insurance system, end-of-life care at home or in nursing facilities has also become more common, alongside a growing preference for dying peacefully rather than receiving life-prolonging treatment in hospitals.
