One fifth of this island is designated a Natural World Heritage Site in 1993, and it is covered by an extensive cedar forest that contains some of Japan’s oldest living trees. The symbol of Yakushima is called Yaku-Sugi, meaning Japanese cedar, which is only used for cedar trees over 1,000 years old. The oldest Yaku-Sugi is considered to be more than 7,000 years old. As a subtropical island with mountains that are nearly 2,000 meters high, Yakushima attracts a lot of rainfall around the year with a local saying that it rains 35 days a month! No matter how the weather is, the walking in the Cedar tree forest is what you cannot miss on this island. You can see many rare plants due to the abundance of water and the changes in temperature at different altitudes. The range of flora is very wide, from coral reef to alpine plants.
