Due to the vastness of the forest, desperate visitors are unlikely to encounter anyone once inside the so-called "Sea of Trees," so the police have mounted signs reading "Your life is a precious gift from your parents," and "Please consult the police before you decide to die!" on trees throughout.
This does not deter determined people to commit suicide in this dense forest. Annually about 70 corpses are found by volunteers who clean the woods but many are forever lost in the very thick woods. Japanese authorities discounted publishing exact suicide numbers in order to not make the place even more popular.
