Shiratani Unsuikyo Ravine on Yakushima Island is a stunning forest known for its moss-covered trees and serene ambiance. This ancient forest, with cedars that can be over a thousand years old, draws visitors with its lush greenery and tranquil atmosphere. The forest is incredibly biodiverse, home to unique species like Yakushima macaques and deer, making it a hotspot for nature lovers.

A highlight is the "Moss Forest," famously known for inspiring scenes in the animated film "Princess Mononoke." The area is crisscrossed with well-maintained trails, ranging from easy walks to more challenging hikes, allowing visitors to explore its breathtaking scenery. Hikers can find themselves surrounded by towering trees, clear streams, and occasional waterfalls, creating a picture-perfect landscape.

Traveler reviews

Fabulous walk through the gorge and on through the forest. The current walk can be completed in an hour with little effort. The drive up is stunning if a little nerve wracking in places. Well worth a visit.

Shiratani Unsui Gorge in Yakushima is one of the most magical places I’ve ever visited. The moss-covered forest feels like stepping into a fantasy world — no wonder it inspired Princess Mononoke. The air is fresh, the sound of running water is soothing, and every corner looks like a scene from a movie. Even in light rain, the mist adds to the mystical atmosphere. The hike can be a bit challenging, but it’s completely worth it. A truly unforgettable experience in Yakushima.

If you're a fan of Hayao Miyazaki's films—especially *Princess Mononoke*—then this place is perfect for you. Whether it's raining or the sun is shining, everything is beautiful.

Beautiful forest very nice trail to walk it’s not very hard or to steep so that’s Nice some part are closed at the moment because of floods so it’s not save to go there but the nicest/longest trail is still good to go. Price is 500 yen you get a map at the entrens

This place was so beautiful and serene. The hike to the moss covered forest was challenging but rewarding with the beautiful scenery. Good hiking shoes is a must as it could be muddy and good grip is needed for climbing up and down the rocks in some sections. Highly recommend bringing snacks or a packaged meal to eat at a rest break for fuel. The hike to the moss forest and back took us around 4 hours! There are bathrooms before you begin your hike and I highly recommend bringing water!
