Overview:Yakushima was registered as an UNESCO World Natural Heritage site 20 years ago. Though small, the island has mountains rising more than 1,000 meters. Elevation differences have created a unique climate zone allowing for 1,900 species of flora from subtropical to subalpine. The island also receives significant rainfall; so much so that people joke it rains 35 days a month. Blanketed in primeval forest, Yakushima attracts visitors from all over the world. Our reporter is Peter Skov, a Canadian photographer living in Japan for 12 years. On Journeys in Japan, Peter focuses his lens on Yakushima's primeval forests, its soaring mountains and its sea turtle spawning grounds.
