Aokigahara
It is known as a popular suicide spot and is reportedly the most popular in Japan. It also ranks as the second in the world after San Francisco's Golden Gate Bridge. There are signs in the forest in both Japanese and English that try to persuade people not to commit suicide. The forest is said to be haunted by the Yūrei (angry spirits) that were left to die. People that go there to take their life usually tie a thread when entering so that if they change their mind and want to make it out alive can locate their path but nobody has ever came out
