Karuizawa · Kyuu Usui Pass Miharashidai (Gunma Prefecture) Complete Guide | Spectacular Views · Access · Highlights Thoroughly Explained
What is Kyuu Usui Pass Miharashidai?
Kyuu Usui Pass Miharashidai is a scenic viewpoint located at approximately 1,200 meters elevation on the prefectural border between Nagano and Gunma Prefectures. This scenic spot, which foreign summer visitors once called the “Sunset Point,” is known as one of the finest scenic locations in the Karuizawa area, offering a 360-degree panorama.
As an observation park where you can see panoramic views of majestic mountains such as Mount Asama, the Myogi mountain range, the Yatsugatake range, the Southern Alps, and the Northern Alps, it attracts many tourists throughout the year. Particularly during autumn foliage season, the colorful landscape spreading below is spectacular, and it is highly regarded as one of the finest autumn foliage viewing spots in the Kanto region.
The observation platform is laid out like a spacious plaza, with blocks and signs indicating the prefectural border. Standing at this location, you can literally step across two prefectures in a single step, providing visitors with a special experience.
Historical Background
Usui Pass has long been known as a difficult section of the Nakasendo Road and served as an important transportation route during the Edo period. With the advent of the Meiji era and the development of Karuizawa as a summer resort, foreign missionaries and vacationers began visiting this pass. Enchanted by the beauty of the sunset, they named it the “Sunset Point,” a name by which it is still affectionately known today.
As the character “kyuu” (old) in Kyuu Usui Pass indicates, it is located on the route before the opening of the current National Route 18 (Usui Bypass), making it a precious place that retains the traces of this historic road.
360-Degree Panorama | Spectacular Views from the Observation Platform
The Majestic Appearance of Mount Asama
The greatest attraction of the observation platform is the majestic appearance of Mount Asama towering behind it. Mount Asama, an active volcano with an elevation of 2,568 meters, is an iconic symbol of Karuizawa, and from the observation platform you can see the entire mountain form up close. Depending on weather conditions, you may also observe volcanic smoke rising, allowing you to experience the power of nature.
Curious Rock Formations of the Myogi Range
To the left, a distinctive group of rocky peaks of Mount Myogi stretches out. The Myogi mountain range, counted as one of Japan’s three most curious mountain landscapes, is characterized by a saw-like ridge, and from the observation platform you can enjoy its unique silhouette.
Distant Views of the Yatsugatake, Southern, and Northern Alps
On days blessed with good weather, you can see the distant Yatsugatake range, and even the mountains of the Southern and Northern Alps. Particularly from autumn through winter when the air is exceptionally clear, mountains more than 100 kilometers away come into view, allowing you to enjoy the grand panorama of the Japanese Alps.
Views of the Kanto Plain
Turning your gaze toward Gunma Prefecture side, the Kanto Plain spreads out below. On clear days, you can sometimes see as far as the Tokyo area, and the contrast between the mountainous terrain and the plain is striking.
Attractions Through the Seasons
Spring (April–June)
The observation platform in spring is a season of fresh greenery. Because of the high elevation, spring arrives later than in the lowlands, and around May the surrounding forest turns a vibrant green. The contrast between snow-capped Mount Asama and fresh greenery is beautiful, and hiking in the refreshing air is enjoyable.
Summer (July–August)
This is the season when the true nature of the summer resort Karuizawa shines. The observation platform at 1,200 meters elevation maintains a cool and comfortable temperature even in midsummer. The contrast between mountains enveloped in deep green and the blue sky is beautiful, allowing you to forget the heat of the city. Early morning cloud seas sometimes form, offering a chance to encounter fantastic scenery.
Autumn (September–November)
The season when Kyuu Usui Pass Miharashidai shines most brightly is autumn foliage season. Typically from mid-October to early November, the surrounding forest turns red and yellow, and the carpet of colored foliage spreading below is breathtakingly beautiful.
The gradation of colors woven by diverse tree species such as Japanese maple, rowan, beech, and larch is truly a work of art painted by nature. Especially in the afternoon slanting light, the autumn foliage becomes even more vivid.
Winter (December–March)
The observation platform in winter is blanketed in snow. Roads may be closed due to snowfall, but on accessible days, spectacular views of pristine white snow fields, blue sky, and snow-capped Mount Asama spread out. The air is extremely clear, allowing you to see distant mountains distinctly—a charm unique to winter.
Enjoying Autumn Foliage Season
Peak Season and Foliage Color Progress
The autumn foliage at Kyuu Usui Pass Miharashidai typically begins to color around mid-October and reaches its peak from late October to early November. Because of the high elevation, autumn foliage can be enjoyed earlier than in Karuizawa’s downtown area.
The color progress varies year to year depending on temperature and weather, but generally proceeds according to the following schedule:
- Early October: Foliage begins to color
- Mid to late October: Peak (early peak)
- Late October to early November: Peak season
- Mid-November: Leaf fall progresses
Best Times for Autumn Foliage Photography
If your purpose is photography, different aspects can be enjoyed depending on the time of day:
Early morning (sunrise to around 8 a.m.): You can capture the fantastic scenery enveloped in morning mist and Mount Asama illuminated by morning light. With few tourists, you can concentrate on photography in a quiet environment.
Afternoon (around 2 p.m. to 4 p.m.): This is the time when autumn foliage illuminated by slanting light shines most vibrantly. You can capture photos with a three-dimensional quality.
Twilight (around sunset): Beautiful sunset befitting the name “Sunset Point” can be enjoyed. The collaboration of autumn foliage and sunset is exceptional.
Expected Congestion Times
Heavy congestion is expected on weekends and holidays during autumn foliage season. The most congested period is around 10 a.m. to 3 p.m., and the parking lot often reaches capacity.
If you wish to avoid crowds, visiting early morning (before 8 a.m.) or evening (after 4 p.m.) is recommended. On weekdays, you can enjoy the scenery relatively peacefully.
