The forest is a popular place for suicides, reportedly the world's second most popular suicide location after San Francisco's Golden Gate Bridge. This popularity is often attributed to the 1960 novel Nami no To by Seicho Matsumoto, which ends with two lovers committing suicide in the forest. However, the history of suicide in Aokigahara dates from before the novel's publication, and the place has long been associated with death: ubasute was allegedly practiced there into the 19th century, and the forest is reputedly haunted by the ghosts of those left to die.
