Aokigahara 青木 ヶ 原, or Jukai 樹 海 sea of trees, is a forest known by its unfortunately nefarious name of "Suicide Forest", mystical and mysterious presence and so much pain.
Aokigahara is a large green area with very tall trees that stretches for 35km² located at the northwestern base of Mount Fuji. The area, originated from Mount Nagaoyama eruption in 864, is characterized by caves left by lava flows that have allowed the formation of dense vegetation, making the area rather "dense" and silent as well as having magnetic disruption due to its geological nature.
