Yakushima is an island with an area of 504.9 km located approximately 60km from Cape Sata in Kagoshima, Kyushu. The island has a rich natural environment and ninety percent of it is forested. This island, along with Shirakami Mountain Range in Tohoku, was registered as one of the first World Natural Heritage Sites in Japan in 1993. Cedars that grow naturally in the mountains of Yakushima at an altitude of over 500m are called Yakusugi. Many of these trees are over 1,000 years old, and the most famous ones are called Jomon Cedar and Kigen Cedar, which are said to be between 2,000 and 7,200 years old. Trekking tours, hiking, and water activities are popular with foreign tourists.
