Japan faces rising mortality and social isolation amid aging population

Japan is facing significant demographic shifts as the number of annual deaths reached approximately 1.6 million in 2024, nearly doubling since 1989. With the baby boomer generation set to reach age 75 or older by 2025, issues regarding end-of-life care and social isolation are becoming more prominent. Reports indicate that in Tokyo, cremation waits can exceed eight days during winter months, and isolated deaths—where individuals are found long after passing—are estimated to reach 22,000 in 2025.

Reflecting these societal trends, recent book bestseller rankings in Japan show a strong interest in themes of aging, mortality, and human nature. Top titles include works on navigating life in one's 70s, fighting war crimes, and understanding human essence. The popularity of these books highlights a growing public discourse on how to live meaningfully while confronting the inevitability of death and the changing structure of Japanese society.
