Yakushima is a subtropical island in Kagoshima Prefecture that is covered by a forest that contains the oldest cedar trees (known as yakusugi), which the most ancient may be over 7000 years old. The most protected and unspoilt areas were declared as UNESCO Natural World Heritage Site in 1993. Its temperate forests gives a fantasy-like ambience, with the gigantic trees covered with moss, has twisted roots, and wide canopies. It was said to be the inspiration of the Studio Ghibli animated film Princess Mononoke, by the creation of Hayao Miyazaki.
