Princess Mononoke and the Deep Connection with Shiratani Unsuikyo Gorge
The acclaimed Studio Ghibli masterpiece “Princess Mononoke” was released in 1997. The place that director Hayao Miyazaki visited while developing the concept and received major inspiration from is Shiratani Unsuikyo Gorge (白谷雲水峡) located in Yakushima Island, Kagoshima Prefecture.
The ancient forest, moss-covered giant trees, and mysterious atmosphere depicted in the film are precisely the very landscape of Shiratani Unsuikyo Gorge. When director Miyazaki visited Yakushima Island, he was deeply impressed by the sight of primeval forest covered in yakusugi cedar trees thousands of years old and deep green vegetation, which is said to have greatly influenced the construction of the world depicted in “Princess Mononoke.”
Shiratani Unsuikyo Gorge is a natural recuperation forest positioned at an elevation of approximately 600 to 1,050 meters. After the film’s release, it became a sacred site visited by many fans from around the world as the “Forest of Princess Mononoke.” In particular, the “Moss Forest” area is known for its fantastical landscape reminiscent of the Forest of the Shishigami.

Thorough Explanation of the Appeal of “Moss Forest”
The Very World of Princess Mononoke
The greatest highlight of Shiratani Unsuikyo Gorge is the Moss Forest spread across an elevation of approximately 800 to 900 meters. This is said to be the model for the Forest of the Shishigami that appears in the film “Princess Mononoke,” and invites visitors into another world.
Characteristics of the Moss Forest:
- A 360-degree moss-covered world: Everything from the ground to fallen logs, rocks, and tree trunks are covered with green moss
- Approximately 600 species of moss: The entire Yakushima Island confirms approximately 600 moss species, with Shiratani Unsuikyo Gorge being a treasure trove
- Mystical light: Dappled sunlight reflected off the moss creates a fantastic green glow
- A world of silence: In the deep forest, only bird songs and water sounds echo
Why is Moss so Abundant Here
Yakushima Island is said to have “rain falling 35 days a month.” Particularly in the mountainous regions, annual precipitation reaches 8,000 to 10,000 mm, which is approximately five times that of Tokyo.
This abundant moisture combined with Yakushima Island’s warm climate and the moderate coolness from elevation creates an ideal environment for moss growth. Furthermore, the high-humidity microclimate created by the yakusugi cedar forest promotes moss proliferation.
Photography Tips
Tips for taking beautiful photos in the Moss Forest:
- Cloudy or rainy days are best: Soft light rather than direct sunlight brings out the moss’s green beautifully
- Early morning or evening: Dappled sunlight creates beautiful light rays
- Macro photography: Close-ups of the moss’s delicate structure
- Wide-angle lens: Capture the overall atmosphere of the forest
- Bring a tripod: A lightweight type is essential for preventing camera shake in the dark forest (while not adding burden to the hike)

Experiences from Actual Visitors
“It Really Was the World of Princess Mononoke”
“As a movie fan, visiting Shiratani Unsuikyo Gorge was my long-held dream. The moment I stepped into the Moss Forest, I got goosebumps from the atmosphere where the Shishigami truly seemed about to appear. Especially the early morning forest enveloped in mist was another world. The guide’s explanation helped me learn the specific points where director Miyazaki drew inspiration, making the emotional impact even greater.” (30-year-old woman)
“More Challenging Than Expected, But Worth It”
“I heard the Taiko Rock course was 5 hours round trip, but it actually took 6 hours taking photos while walking slowly. The final climb to Taiko Rock was particularly challenging. However, the 360-degree panorama from the summit and the fantastical beauty of the Moss Forest made me forget my fatigue. Bringing trekking poles turned out to be the right call.” (40-year-old man)
“More Beautiful on Rainy Days”
“I was visiting on a rainy morning. At first I was disappointed, but my guide said ‘The moss is most beautiful on rainy days,’ and he was right.

As long as you’ve properly prepared for rain protection, rainy days are also recommended.” (20-year-old woman)
