Yakushima's Mystical Forest
Yakushima is a small island south to Kagoshima where the high amount of rainfall has allowed nature to develop in a unique manner where several generations of cedar trees grow on top of each other and beautiful moss covers most rocks and tree trunks.
Even with a terrible weather, the hike is an enjoyable one. As a matter of fact, the mist added to the ethereal atmosphere, allowing the green of the moss to really shine.
The specific area named Shiratani Unsuikyo inspired the master Hayao Miyazaki to make the movie "Princess Mononoke".
