Mikuni Pass: The Charm of Hokkaido’s Highest National Road Point
Basic Information About Mikuni Pass
Mikuni Pass is located on National Route 273 and sits at the border between Kamikawa and Kamishihoro towns. At 1,139 meters in elevation, it is the highest pass on any national road in Hokkaido, and its magnificent views have made it beloved by many drivers and riders.
The name of the pass derives from the fact that it once stood at the boundary of three provinces: Ishikari, Tokachi, and Kitami. Today it has become an important transportation link connecting the Kamikawa and Tokachi districts, and it is particularly busy with tourists from summer through autumn.
The Spectacular Views from Mikuni Pass Observatory
An observatory has been established at Mikuni Pass, and the view from here is nothing short of spectacular. Below the observatory, a red bridge called Matsumi Bridge spans the sea of trees, and in the distance, a magnificent panorama of the Daisetsuzan mountain range stretches out.
On clear days, you can see all the way to the Tokachi Plain, and the scenery truly captures the grand scale that is characteristic of Hokkaido. The observatory also has a café and rest house, where you can relax and enjoy the views.
Nukabira Lake: A Mysterious Landscape Created by a Manmade Reservoir
Overview and History of Nukabira Lake
Nukabira Lake is a manmade reservoir located in Kamishihoro town, formed in 1955 when the Otofuke River was dammed to create the Nukabira Dam. With a circumference of approximately 33 kilometers and a maximum depth of about 40 meters, it plays an important role as a power generation reservoir.
Despite being a manmade lake, it harmonizes beautifully with the surrounding primeval forest and the natural scenery of Daisetsuzan National Park, offering beautiful views throughout the four seasons. Particularly during the autumn foliage season, the brilliantly colored mountains reflected in the lake’s surface captivate all who visit.
Taushubetsu River Bridge: The Phantom Bridge’s Mystery
The most famous feature of Nukabira Lake is Taushubetsu River Bridge. This bridge is a concrete arch bridge from the former Japanese National Railway Shihoro Line, and because it appears and disappears from the lake’s surface depending on seasonal water level fluctuations, it is called the “phantom bridge.”
From January to June during the dry season, the bridge emerges completely from the water’s surface, allowing visitors to see its graceful arch structure. Conversely, during the flood season from July onward, it gradually becomes submerged, and from August to October it is completely underwater.
This fantastical landscape is extremely popular with photography enthusiasts and tourists alike, and particularly during early morning hours when mist rises, an almost otherworldly mystical scene unfolds.
Detailed Route Information from Mikuni Pass to Nukabira Lake
Basic Route Information
The route from Mikuni Pass to Nukabira Lake follows National Route 273 southbound toward Tokachi for approximately 20 kilometers. The journey from the pass to Nukabira Hot Spring town takes about 25 to 30 minutes by car, but it is recommended to drive slowly to enjoy the scenery.
The route is relatively well-maintained, but features many curves and steep grades near the pass, so careful driving is essential. In winter, the road may be closed due to snow and ice, so it is important to check road conditions in advance.
Main Attractions Along the Route
Shortly after leaving Mikuni Pass, you’ll see Matsumi Bridge. This bridge spans 486 meters and stands approximately 40 meters high, making a striking impression as it crosses through the sea of trees. There is a parking area near the bridge entrance, making it a popular spot for commemorative photos.
As you descend from the pass, a pleasant drive through coniferous forests continues. In autumn, the surrounding trees turn color, and you can enjoy the beautiful scenery of a foliage tunnel with gradations of red and yellow.
As you approach Nukabira Lake, the road becomes a lakeside drive, with the lake’s surface appearing and disappearing among the trees. On fine days, the sky and mountains reflected in the water are beautiful, and you’ll likely want to stop the car multiple times for photographs.
Best Seasons and How to Enjoy the Four Seasons
Spring (May-June): Season of New Growth
The route from Mikuni Pass to Nukabira Lake in spring is a season when new leaves sprout as snow melts. From late May through June, the mountains are enveloped in fresh green, and you can feel the breath of nature liberated from winter’s harshness.
During this period, the water level of Nukabira Lake is low, and Taushubetsu River Bridge is completely visible. The contrast between snow-capped peaks of the Daisetsuzan range and fresh greenery is beautiful, allowing you to enjoy scenery unique to spring.
Summer (July-August): Cool Highland Breezes
In summer, Mikuni Pass, being at high elevation, is cooler than lowland areas, making it ideal as a summer retreat. Temperatures are 5 to 10 degrees lower than in the plains, and even in midsummer, it remains comfortable. The contrast between lush green vegetation and blue sky is beautiful, with scenery that truly captures Hokkaido’s refreshing character.
Around Nukabira Lake, activities such as canoeing and fishing are also popular during this season. However, this is when Taushubetsu River Bridge begins to submerge, so if you wish to see the bridge, it is recommended to visit by early July.
Autumn (September-October): Spectacular Fall Foliage
The route from Mikuni Pass to Nukabira Lake is most beautiful during the autumn foliage season. From late September through early October, Nanakamadoberry, maple, and birch trees turn red and yellow, transforming the entire mountain into a landscape like a traditional Japanese tapestry.
The view from Mikuni Pass Observatory is particularly spectacular, with the sea of trees below becoming a mosaic pattern of red, yellow, and green—a beauty that cannot be adequately expressed in words. As this period attracts many tourists, visiting early in the morning or on weekdays is recommended.
The Nukabira Lake area is also beautiful with autumn colors, and the brightly colored mountains reflected in the lake create a scene like a painting. Taushubetsu River Bridge also becomes partially visible as water levels begin to drop.
Winter (November-April): Seasonal Closure and Road Closure
Mikuni Pass is typically closed to traffic from early November through late April due to winter conditions. During this period, snow and ice make driving dangerous, and the route cannot be used.
However, the Nukabira Lake area can still be visited in winter, where you can enjoy the mystical landscape of a frozen lake and snow-covered scenery. Taushubetsu River Bridge also emerges on the frozen lake’s surface, creating a mysterious sight unique to winter.
