The suicide forest actually exists in Japan. In Japanese, it is called Aokigahara, and is at the bottom of Mount Fuji. The forest range covers around 14 square miles. Once you enter the forest, it's completely silent - no sounds of birds singing or animals rustling around. The number of suicides taking place there has increased yearly, and the Japanese government has placed signs around the perimeter of the forest, in Japanese and in English, urging people to stay away. There is a government department with the sole assignment of periodically going into the forest to remove as many bodies as possible.
Despite taking place somewhere in Japan, the entire film was shot in Vancouver Canada.
This is not the first time Kaitlyn Leeb and Graham Wardle have worked together. They both work on the TV series "Heartland" playing Ty Borden and Cassandra "Cass" Lee Odell, respectively.
