From the World Heritage Inscription:
Located in the interior of Yaku Island, at the meeting-point of the palaearctic and oriental biotic regions, Yakushima exhibits a rich flora, with some 1,900 species and subspecies, including ancient specimens of the sugi (Japanese cedar). It also contains a remnant of a warm-temperate ancient forest that is unique in this region.
Yakushima is a very special place. A about an hour ferry ride from Kagoshima, the interior of Yakushima (Yaku Island) is several thousand feet above sea level and often in the clouds.
Not only is it a beautiful place, but the food I had on Yakushima is some of the best I’ve experienced on my trip.
