On my recent trip to Japan after visiting Mount Fuji I went to the "Suicide Forest" (info below from Wikipedia). It's an amazing and beautiful place and eery due to the lack of noise. Adding to the eeriness is the fact that a compass won't work in this area because of the volcanic rock it sits on.
There is also an excellent video by VICE you can watch here.
"Aokigahara (青木ヶ原), also known as the Sea of Trees, is a 35-square-kilometre forest that lies at the northwest base of Mount Fuji in Japan. The forest contains a number of rocky, icy caverns, a few of which are popular tourist destinations. Due to the wind-blocking density of the trees and an absence of wildlife, the forest is known for being exceptionally quiet.
The forest has a historic association with demons in Japanese mythology and is a popular place for suicides despite numerous signs, in Japanese and English, urging people to reconsider their actions."
