Japan is facing a growing social crisis with the rise of so-called 'lonely deaths' (kodokushi), a phenomenon that mainly affects the elderly but also young people and adolescents. According to official data for fiscal year 2025, ending March 31, 2026, 76,941 people died alone in the country, an increase of 921 cases from the previous year.
Of this total, 22,222 cases were classified as koritsushi — when the body is found more than eight days after death — and in 7,148 cases the bodies were discovered after more than a month. The statistics include 57 adolescents and 753 people aged 20 to 30, indicating that isolation affects all age groups.
Experts attribute the phenomenon to deep social changes. 'The end of the traditional nuclear family and the advance of individualization are the main factors,' said Izumi Tsuji, professor of cultural sociology at Chuo University in Tokyo. He highlighted that migration to large cities and apartment living have weakened community ties.
The Japanese government has implemented measures to combat isolation. In 2021, it created the position of Minister of Loneliness and Isolation, and in April 2024, the Law on Measures against Loneliness and Isolation came into effect, encouraging the creation of local support agencies and community integration programs.
An example of community response emerged after the earthquake and tsunami of March 11, 2011, which devastated the coastal city of Ishinomaki. Katsuyuki Ito founded the organization Rera, which assists the elderly and people with disabilities in daily tasks, such as transportation to hospitals and banks. 'Many lost their families and have little contact with other people,' said Kei Ueno, a member of the organization. 'They say the best time of day is when the volunteers arrive.'
Kodokushi has become one of the greatest social challenges of contemporary Japan, in a country where rapid aging and urban isolation demand new forms of coexistence and support.
