A Place Immersed in the Autumn Colors of Okuchichibu – Nakatsukyo
Nakatsukyo is a valley stretching deep within the mountains of Okuchichibu. Unlike other spots in the Chichibu region that have been developed for tourism, this area is known for preserving untouched nature.
The rocky cliffs, carved over countless years by the river, the trees clinging to their slopes, and the vibrant autumn leaves that blanket the mountains define the scenery. The moment you arrive, you can feel the raw power of nature itself.
Natural Sculptural Beauty Free from Human Influence
The greatest appeal of this place lies in the minimal presence of human influence. As you walk through the valley, all that enters your sight are rocks, rivers, trees, and the sky. It is a world completely unlike artificially designed gardens or tourist attractions.
The autumn foliage follows its own rhythm. Layers of red, yellow, and green overlap naturally, creating intricate and beautiful color combinations that seem the result of happy accidents.
Color Gradients Shaped by Nature
The autumn leaves in Nakatsu Valley display remarkably rich layers of color. Depending on sunlight, elevation, and the variety of trees, a wide range of hues blends together on the same mountainside. Deep reds and oranges fill the forest’s interior, while trees along the river still retain patches of green.
When these colors come together from a distant viewpoint, the scenery resembles a vast painting—an artwork created entirely by nature itself.
A Three-Dimensional Landscape Formed by the Gorge and Autumn Leaves
The unique depth and height of the gorge’s terrain further emphasize the three-dimensional quality of the autumn foliage. Clear water flows quietly along the valley floor, and the cliffs on both sides are lined with overlapping trees in vibrant colors.
Sunlight filtering through the branches reflects on the water’s surface, occasionally sparkling like a natural light performance. Unlike artificial illumination, the scenery changes dramatically depending on the time of day, adding to its charm.


The River and Rocks as Silent Sculptors
Over countless years, the river has carved the rocks into dramatic forms, and the trees that grow alongside these formations follow nature’s unpredictable design. The combination of these elements with autumn’s vibrant colors produces a sculptural scene that needs no human touch.
Experiencing the Seasonal Shift Up Close
Walking through Nakatsukyo during autumn allows visitors to witness the subtle changes in nature firsthand. Each turn of the path, each variation in light, reveals new layers of color and texture, emphasizing the fleeting yet powerful beauty of the season.
