Aokigahara (青木ヶ原?), also known as the Suicide Forest or Sea of Trees (樹海 Jukai?), is a 35-square-kilometre (14 sq mi) forest that lies at the northwest base of Mount Fuji in Japan. The forest contains a number of rocky, icy caverns, a few of which are popular tourist destinations.[1] Aokigahara forest is dense, shutting out all but the natural sounds of the forest itself.[2]

The forest has a historic association with demons in Japanese mythology and is a popular place for suicides (57 in 2010)[3] despite the sign posted in Japanese at the head of the main trail urging suicidal visitors to think of their families and contact a suicide prevention association.[4]


The forest floor consists primarily of volcanic rock and is difficult to penetrate with hand tools such as picks or shovels. The forest itself is very dense and one can get lost easily if leaving the official trails. Because of this, hikers and tourists trekking through Aokigahara have begun to use plastic tape to mark their paths so as to avoid getting lost in recent years.[5] Past the designated trails leading to tourist attractions such as the Ice Cave and Wind Cave, the first kilometer of the forest is littered with tape and other rubbish left by tourists, despite the officials' attempts to remove it. After the first kilometer into Aokigahara towards Mount Fuji, the forest is in better condition, with little to no litter and few obvious signs of human presence.[citation needed]

Visitors and suicides[edit]

The forest is a popular place for suicides, reportedly the most popular in Japan. Statistics vary, but what is documented is that during the period leading up to 1988, about 100 suicides occurred there every year.[6]

In 2003, 105 bodies were found in the forest, exceeding the previous record of 78 in 2002.[7] In recent years, the local government has stopped publicizing the numbers in an attempt to downplay Aokigahara's association with suicide.[8] In 2004, 108 people killed themselves in the forest. In 2010, it is estimated that more than 200 people attempted suicide in the forest, 54 of whom completed the act.[3] Suicides are said to increase during March, the end of the fiscal year in Japan.[9] As of 2011, the most common means of suicide in the forest were hanging and drug overdoses.[10]

The high rate of suicide has led officials to place a sign at the entry of the forest in Japanese, urging suicidal visitors to seek help and not kill themselves. Annual body searches have been conducted by police, volunteers, and attendant journalists since 1970.[11][12][13]

The site's popularity has been attributed to the 1960 novel Kuroi Jukai (Black Sea of Trees) by Seichō Matsumoto.[14] However, the history of suicide in Aokigahara predates the novel's publication, and the place has long been associated with death: ubasute may have been practiced there into the nineteenth century, and the forest is reputedly haunted by the Yūrei (angry spirits) of those left to die.[8]
