Yakushima Shiratani Unsuikyo Day Tour: Hike Through Moss-Covered Forest to Taiko-iwa Rock

A Guided Day Hike from Shiratani Unsuikyo to Taiko-iwa Rock

This tour takes you through the moss-covered forest of Shiratani Unsuikyo and on to Taiko-iwa Rock and back. The round trip is about 5.5 km, and the hike takes around 6 hours.

Groups are kept small, with a maximum of 6 guests per guide, and the tour runs with as few as 1 participant. Even if you're travelling Yakushima solo, you can explore the forest alongside other hikers.

The highlights are the forest carpeted in moss and the views of ancient woodland and mountain ridges from Taiko-iwa. It's a full day that lets you enjoy both being deep inside the forest and looking out over it.

First, Head from Your Accommodation to the Trailhead

On the day, a free shuttle picks you up from accommodations in the service area (Miyanoura, Anbo and Onoaida) and takes you to the trailhead. If you're staying outside this area, check in advance how to get to the designated meeting point.

Hiking gear such as boots, rainwear and backpacks can be rented for free if you apply in advance. Register the items and sizes you need, and you'll have less to bring with you to Yakushima.

Eat breakfast at your accommodation before pick-up, or bring snacks you can eat during breaks. Check the information sent after booking for other things to bring, such as drinks and food.

Next, Head Deeper into the Forest Past Streams and Giant Cedars

From the trailhead, you'll follow your guide along a path of rocks and tree roots. Listening to the sound of running water and taking in the mossy rocks and trees, you'll make your way into the forest of Shiratani Unsuikyo.

Along the way, you'll encounter trees that have grown over many centuries, including cedars with large hollows at their base. Stand close and look up, and you'll feel the true scale of their trunks and roots in a way photos can't quite capture.

The trail has ups and downs, so watch your footing and follow your guide's pace.

At Last, the Lush Green Moss Forest

In the Moss Forest (Kokemusu no Mori), everything from rocks and fallen trees to tree roots is covered in moss. Stop and look around, and you'll see layer upon layer of green in countless shades.

After rain, droplets cling to the moss and leaves, and when sunlight breaks through, the greens take on a different look. Take a closer look, too, at small details like tiny mushrooms growing on fallen logs.

You may also spot Yakushima's native deer (Yakushika) and macaques (Yakuzaru) along the way. They're wild animals, so whether you see them depends on the day.

Beyond the Forest, Take In the Mountains from Taiko-iwa Rock

From the Moss Forest, the trail climbs further to Taiko-iwa Rock. From the top of the rock, you can gaze over the deep forest filling the valley and Yakushima's mountains rolling beyond it.

After walking under the trees, the view suddenly opens up here. The forest changes with the seasons, from wild cherry blossoms in spring to lush green in summer and autumn colours. The view also depends on the day's weather, including clouds and fog.

After enjoying the scenery, you'll return to the trailhead with your guide. Depending on participants' fitness and other factors, the tour may turn back at the Moss Forest without continuing to Taiko-iwa.
