Known as “Suicide Forest”, this isn’t a town per se; but neither is Helltown, really. Plus, it’s called suicide forest… or Demon Forest, which is no less terrifying.
Apparently one of the world's most popular suicide spots, Aokigahara has seen more than 500 people off themselves since the 50s. There’s even an annual body hunt, and though officials now keep the numbers under wraps, volunteers found 105 bodies in 2003, and 108 in 2004. In 2010, police records indicated 247 people attempted suicide in the forest. That's also the year The Last Airbender came out. Maybe just a coincidence. Maybe not.
Seicho Matsumoto allegedly started the trend with his novel Kuroi Kaiju (Black Sea of Trees), in which two lovers commit suicide in the forest. Today, nooses, signs asking people to reconsider, personal effects like wallets and jewelry, and, far too often, rotting bodies litter the woods. Don't Google image search this place unless you feel like looking at dead people. Obviously, the forest is said to be haunted by the tormented souls of those that killed themselves here.
