Basic Information and Charm of Kaminohdaira Highland
Location and Geographic Features
Kaminohdaira Highland is located at the foot of Mount Kenashi (elevation 1,650m) and spreads across the eastern side of Nozawa Onsen Village. This region is known as one of Japan’s heaviest snowfall areas, recording several meters of snow accumulation during winter. This abundant snowmelt seeps underground, filters through the beech forest over approximately 50 years, and becomes the source of Nozawa Onsen’s high-quality hot spring water and spring water.
The highland area spanning elevations of 1,300m to 1,650m has temperatures 5-10 degrees lower than the plains, providing a cool and comfortable environment even in summer. These climate conditions support the growth of abundant broadleaf forests, including beech trees.
Ecosystem of the Primeval Beech Forest
The most distinctive feature of Kaminohdaira Highland is its exceptionally beautiful and densely packed primeval beech forest. Beech trees, also called “the mother of forests,” nurture a rich ecosystem supporting diverse flora and fauna. The sight of giant trees towering over 20 meters high standing in rows is spectacular, and walking through the forest envelops you in a fantastical space created by dappled sunlight.
On the beech forest floor, mountain vegetables grow in spring, various wildflowers in summer, and mushrooms in autumn, allowing for nature observation rich in seasonal changes throughout the year. The area is also home to various wild animals including Japanese black bears, Japanese serows, squirrels, and birds, and with luck, you may observe them.
The Mystical Landscape of Suttaka Lake
Suttaka Lake, located at approximately 1,300m elevation, is an iconic landmark of Kaminohdaira Highland. The quiet lake surface surrounded by beech forest displays various expressions depending on season and weather. On early mornings, mist may rise from the lake, creating a fantastical atmosphere.
A walking trail has been developed around the lake shore, allowing you to leisurely explore while enjoying nature. A campground has been set up near the lake, and from early July through late August, nature enthusiasts pitch tents and enjoy outdoor experiences.
Seasonal Charm and Highlights
Spring at Kaminohdaira Highland (May-June)
Spring, arriving with the snowmelt, is the season of fresh greenery. From late May through June, beech leaves bud all at once, and the entire forest turns a vibrant green. The fresh greenery of this season has a transparent quality, and the beauty of leaves glowing as light shines through them is exceptional.
In the spring forest, alpine wildflowers such as dogtooth violets, Japanese snow bells, and false hellebores bloom delicately. Additionally, the chirping of birds like bush warblers, paradise flycatchers, and narcissus flycatchers echoes through the forest, making it an ideal season for birdwatching.
Summer at Kaminohdaira Highland (July-August)
Summer at Kaminohdaira Highland provides an ideal environment as a summer retreat. In highlands above 1,400m elevation, temperatures rarely exceed 25 degrees even at the height of summer, offering a cool and comfortable experience. The beech forest covered in deep green acts like a natural air conditioner, offering healing to those visiting for forest bathing.
The Suttaka Lake campground operates from early July through late August, offering experiences such as stargazing, early morning lakeside walks, and forest bathing where you can become one with nature. Due to the high elevation, nighttime temperatures can drop below 10 degrees, so be sure to prepare warm clothing.
Autumn at Kaminohdaira Highland (September-October)
The autumn foliage season brings the most visitors to Kaminohdaira Highland. It typically begins to change color around late September and reaches its peak from early October through late October.
The autumn colors created by broadleaf trees including beech, maples, rowan, and birch form a masterpiece of natural art with gold as the base tone, while displaying gradations of red, orange, and yellow. The yellow foliage of beech trees, in particular, has a transparent quality, and the way it glows golden in sunlight is breathtaking.
Around Suttaka Lake, you can enjoy “reflected autumn leaves” where foliage is mirrored in the lake surface, attracting many photography enthusiasts. Early morning and dusk hours are especially magical, making it a popular photography spot.
Since the timing of peak foliage varies depending on weather conditions, it is recommended to check the latest information from Nozawa Onsen Tourism Association or Nozawa Onsen Mountain Resort Tourism Bureau official websites before visiting.
