It's said that its filled with Yūrei, spirits from people that had killed themselves before in that same forest, making it a haunted forest. Everyone avoided the forest, some people and tourists visited it, finding themselves with the rotting corpses that lay there. No one that has stayed the night there has ever survived, losing their minds, going insane and killing themselves or the people that was with them...
