Nonomi Kogen | A Paradise of Beech Virgin Forest in a Hidden Realm
Geographic Features and Natural Environment
Nonomi Kogen is located in Sakae Village, at the northernmost tip of Nagano Prefecture, within the Akiyama Gorge area. Close to the prefectural border with Niigata, its high elevation of 1,020 meters creates a cool, comfortable climate even in summer.
The area’s greatest feature is the preservation of rare beech virgin forest across a wide expanse of Japan. Beech forests are also called “green dams,” serving the important role of storing abundant water and nurturing diverse ecosystems. The beech forest of Nonomi Kogen contains many giant trees with ages exceeding several centuries, creating an ideal environment for forest bathing.
Nonomi Pond | A Mirror of Mystery Shining in the Highlands
At the center of the highlands sits Nonomi Pond, peacefully spanning approximately 2 kilometers in circumference with a maximum depth of 16 meters. Though originally constructed as an irrigation reservoir, it has become the symbolic landmark of Nonomi Kogen.
On clear days, the blue sky and surrounding beech forest are vividly reflected on the water’s surface, creating a mirror-like beautiful landscape. On calm mornings without wind, particularly beautiful reflections can be seen, attracting many photographers seeking perfect shots.
A walking trail encircles the pond and can be completed in approximately one hour. While walking, you can feel the breath of the beech forest and listen to the songs of wild birds—a luxurious way to spend time.
Nonomi Kogen in Four Seasons | Seasonal Highlights
Spring (Late May–June) | The Season of Snowmelt and Skunk Cabbage
Spring comes late to Nonomi Kogen, with the snowmelt beginning earnestly from late May through June. The season’s greatest highlight is the blooming of Japanese skunk cabbage (mizubasho) in wetlands.
Around early June when snowmelt water is abundant, pure white skunk cabbage flowers bloom simultaneously in the wetlands around Nonomi Pond. Their pristine, delicate white spathes gleaming against the backdrop of fresh green beech forest represent the epitome of highland spring.
Skunk cabbage typically peaks from early to mid-June, though dates vary slightly with weather conditions. Morning and evening temperatures are still bitterly cold during this period, so it’s recommended to dress warmly when visiting.

Summer at Nonomi Kogen becomes a paradise for forest bathing, enveloped in rich green. With an elevation exceeding 1,000 meters, temperatures remain around 25 degrees Celsius even in midsummer—an ideal retreat.
As beech leaves grow thick, the entire forest becomes a tunnel of deep green—the season most suited for hiking. Walking through the forest with dappled sunlight creates a unique sense of quiet and freshness unavailable in cities.
Nonomi Kogen Campground operates during summer months, offering tent camping and bungalow accommodations. At night, a blanket of stars spreads overhead, with the Milky Way clearly visible—an excellent stargazing spot.
Autumn (Late September–Mid-October) | Spectacular Beech Virgin Forest Foliage
Nonomi Kogen attracts the most visitors during fall foliage season. From late September through mid-October, beech, birch, and maple trees turn simultaneously, painting the entire highland in gold and crimson.

Fall colors typically peak in early October, though dates vary with elevation and weather. Popular photography spots include the pond’s northern viewing area, campground vicinity, and surrounding wetlands, each offering different angles on the foliage.
Fall foliage season brings congestion at certain times. The parking lot may fill up, especially weekends between 10 AM and 2 PM. Early morning or weekday visits are recommended.
