Japan's National Police Agency reported 76,941 people died alone in their homes in 2025, nearly one-third of all deaths handled by police. People over 65 accounted for 76.6% of cases at 58,919 deaths, up 875 from 2024. About 29% of bodies were discovered eight or more days after death, highlighting a persistent social isolation crisis in Japan's aging society. The government is treating this as a policy concern requiring intervention strategies.
