You can't visit Yakushima without doing this trek. Highly recommend to hire or bring proper raincoats (top and bottom) and hiking boots. The weather can change on a dime here and as one of the wettest places on earth the moisture somehow just seeps in.
I was extremely out of shape but took the trek very slowly with my elderly parents and finished return trip in around 5.5hrs, much longer than most people would take. The final leg to the top is very steep and a continuous climb up so may not be suitable for everyone.
Not much to say about the trail that others have not said. But the photos barely do it justice. The place is magical and mesmerising. Don't forget to stop and look around.
There is limited parking but somehow the attendants managing it make it work. You can also borrow a wooden walking stick from hr pile at the ticket entrance.
A beautiful forest trail. I definitely recommend it! We arrived by bus from the harbor stop. ¥560 per person – the last stop – entrance to the park. Almost all the trails were closed due to the weather. We were worried that this trip wouldn't go ahead, but the hotel staff, before we left, let us know which trail was open. During our visit, we had a brief period of better weather (about 1.5 hours), and then a downpour brought us down. It's cooler at the park level than at the harbor level, making it more pleasant, but the humidity is high. There are many streams and creeks. I recommend being well-prepared for rain ☺️. If necessary, there are places in town where you can rent equipment.
4 hour hike to the top for great view lookout. hiking boots were needed as there were tiny streams to cross. we went on 15 May 2026, and it did not rain. Weather was great. you get to see moss covered forest that inspired princess mononoke from studio ghibli. we didn’t get a guide, but if you have mobility issues or want peace of mind, we saw some people with guides.
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.
An incredible experience. This tranquil place is inspirational to walk through and leaves a lasting impression on your mind. This is the place that inspired the film 'Princess Mononoke'.
There's so much to see. I saw monkeys on the way in, and the entrance has a beautiful waterfall that's worth the drive for that alone. There's lots of mossy rocks and trees, several Japanese trees whose age dates back to around the years of the Roman Republic, and lots of waterfalls and streams.
Some of the paths have steep climbs, and it was physically challenging in parts, though I had no hiking gear bar the boots. Hiking poles would've made the return journey more enjoyable.
Recommended times on the map are conservative. I did the longest walk which recommends 4 hrs, though even with many photo breaks and some rest it was still only about 3 hrs or less.
Time the course you want to do depending on your fitness level, and climbing confidence. If you want to give yourself time and do multiple trails, go first thing in the morning and pack water and snacks. Though one water bottle is enough as the water from the streams are delicious.
