Kodokushi (孤独死) or lonely death refers to a Japanese phenomenon of people dying alone and remaining undiscovered for a long period of time. The phenomenon was first described in the 1980s. Kodokushi has become an increasing problem in Japan, attributed to economic troubles and Japan's increasingly elderly population. It is also known as koritsushi (孤立死) and dokkyoshi (独居死).
The first instance that became national news in Japan was in 2000 when the corpse of a 69-year-old man was discovered three years after his death; his monthly rent and utilities had been withdrawn automatically from his bank account and only after his savings were depleted was his skeleton discovered at his home. The body had been consumed by maggots and beetles.
Statistics regarding kodokushi are often incomplete or inaccurate. Japan's public broadcaster NHK reported that 32,000 elderly people nationwide died alone in 2009. The number of kodokushi tripled between 1983 and 1994, with 1,049 lonely deaths reported in Tokyo in 1994. In 2008, there were more than 2,200 reported lonely deaths in Tokyo. Similar numbers were reported in 2011. One private moving company in Osaka reported that 20 percent of the moving company's jobs (300 per year) involved removing the belongings of people who had died lonely deaths. Approximately 4.5% of funerals in 2006 involved instances of kodokushi.
Kodokushi most often affects men in their 50s and people over 65 years old.
Several reasons for the increase in kodokushi have been proposed. One proposed reason is increased social isolation. A decreasing proportion of elderly Japanese people are living in multi-generational housing and are instead living alone. Elderly people who live alone are more likely to lack social contacts with family and neighbors, and are therefore more likely to die alone and remain undiscovered.
Economic reasons for kodokushi have also been proposed. Many incidents of kodokushi have involved people who were receiving welfare or had few financial resources. McDonald suggests that the "Japanese trait of uncomplaining endurance," or gaman, discourages people in need from seeking help from neighbors and authorities. Victims of kodokushi have been described as "slipping through the cracks" between governmental and familial support.
Additionally, the economic slump in Japan since 1990 has been cited as contributing to the increase in lonely deaths. Since 1990, many Japanese businessmen have been forced into early retirement. Many of these men have never married and become socially isolated when removed from the corporate culture.
Masaki Ichinose, head of the University of Tokyo's Institute of Death and Life Studies, hypothesizes that the increase in kodokushi is linked to Japan's contemporary culture which ignores death. Several hundred years ago, Japanese people commonly confronted death; for example, bodies were typically buried by family members. In contrast, in modern Japan, there are fewer opportunities to witness death and death is not readily discussed.
Hypothesized psychological reasons for the increase in kodokushi include social apathy and life stress. Social isolation is used as a coping mechanism to avoid stressful situations. Scholars have also analyzed how "contemporary discourse constructs kodokushi as a “bad death” and as evidence for the decay of “traditional” social bonds, such as family, neighborhood and company ties," with government and community initiatives thereby pushing "to implement new welfare systems, often suggesting to re-activate lost family and community bonds" 
Some districts in Japan have begun campaigns and movements to prevent lonely deaths. Officials in Tokyo's Shinjuku Ward have started a kodokushi awareness campaign that includes scheduled social events and checking in on the well-being of elderly citizens.
