Tips for Enjoying Gunma's Scenic Spots on a Nature Trip
Gunma brings together mountains around 2,000 m high, one of Honshu's largest marshes, volcanic lakes, a nationally designated waterfall, and beech-covered highlands, offering a quieter experience than urban sightseeing.
Travelers to Japan can build an itinerary more easily by basing themselves at hot spring towns like Kusatsu, Ikaho, Shima, and Minakami, or at railway stations like Takasaki and Numata, and choosing waterside or highland spots to match the weather.

Group Your Travel by Area
Since Gunma's nature spots are spread widely across the prefecture, it's important not to cram too many distant areas into the same day.
Grouping destinations by region—such as Minakami, Tone-Numata, and Agatsuma—helps reduce travel time and fatigue.
Mountain Scenic Spots: Mount Tanigawa, Oze, and Mount Akagi
Gunma's mountain scenery varies by location, from rugged rock walls and sweeping marshlands to peaks surrounding caldera lakes.
Even on a trip without serious climbing, choosing viewpoints, boardwalks, or lakeshores lets you feel the scale of nature.
Mount Tanigawa & Ichinokurasawa: See Dramatic Rock Walls and Lingering Snow
Mount Tanigawa rises 1,977 m on the border of Gunma and Niigata and is the signature peak of the Minakami area.
The north-facing Ichinokurasawa is counted among Japan's three great rock faces. At Ichinokurasawa Deai, at an elevation of about 870 m, you can experience the sheer walls and depth of the valley up close.
You can reach the Deai viewpoint on foot along a path through beech forest or use the electric guide bus operated to support environmental conservation.
Even if you take the ropeway to Tenjindaira, mountain weather can change quickly, so check the latest operating and access information from official transport and facility sources before heading out.
For varied photos, try both wide-angle shots of the entire mountain and closer compositions that capture the texture of the rock and snow.
Ozegahara: View One of Honshu's Largest Marshes from the Boardwalks
Ozegahara is one of Honshu's largest high-altitude marshes, spreading at about 1,400 m elevation within Oze National Park, which includes Katashina Village in Gunma Prefecture.
Small ponds called chitō dot the marsh, while skunk cabbage (mizubashō), Nikkō-kisuge daylilies, and cotton grass (watasuge) create a layered landscape against the mountain ridges.
The boardwalks are essential for protecting the marsh, so stay on them while taking photos and keep a respectful distance from the plants.
Skunk cabbage typically peaks from mid-May to early June, while daylilies bloom from mid- to late July. Visiting outside peak hours can make it easier to savor the marsh's atmosphere.
Mount Akagi & Kakumanbuchi: Enjoy a Caldera Lake and Marsh Together on a Stroll
Mount Akagi is a composite volcano rising over Maebashi City, and its summit caldera holds Lake Onuma, a caldera lake at about 1,340 m elevation.
You can enjoy combining the lakeshore scenery around Lake Onuma with a marsh walk at Kakumanbuchi on the southeast side.
Kakumanbuchi is a small marsh at about 1,360 m elevation, also called "Mini Oze," and is ideal for observing alpine plants and ponds from the boardwalks.
Clear skies are beautiful, but the sight of the marsh floating in mist is another distinctive charm of Mount Akagi.
Lake and Highland Scenic Spots: Lake Haruna, Lake Nozori, and Tambara Highland
Lake and highland scenery suits those who want to enjoy calm, open space rather than the drama of the mountains.
A slower itinerary that takes in the water, grasslands, and forests lets you appreciate Gunma's nature even between destinations.
Lake Haruna: See Mount Haruna-Fuji Reflected in the Water
Lake Haruna is a caldera lake formed by Mount Haruna's volcanic activity and is one of Gunma's signature lake landscapes at about 1,100 m elevation.
From the lakeshore, frame Mount Haruna-Fuji (1,391 m) beyond the water to capture the relationship between the mountain and lake.
The area offers early-summer azaleas and autumn foliage, and nearby Ikaho Onsen makes a convenient base for combining nature with hot springs.
Lake Nozori: Enjoy Highland Skies at the "Lake in the Sky"
Lake Nozori is a reservoir in the mountains of Nakanojo Town, with a surface elevation of about 1,513 m and a shoreline circumference of roughly 12 km. Known as the "Lake in the Sky," it offers expansive highland views and alpine flora.
More than 300 alpine plant species are said to grow around the lake, including early-summer azaleas and Nozori-kisuge daylilies. Along the shore, the broad sky, changing water color, and seasonal plants create constantly shifting views.
Since it is closed for winter roughly from late November to late April, it's reassuring to check road and facility information before visiting.
Tambara Highland & Tambara Marsh: Walk Through the Beech Forest and "Little Oze"
Tambara Highland is a natural area on the western slope of Mount Hotaka in Numata City, nicknamed "Little Oze" for its old-growth beech forest and marsh scenery.
At Tambara Marsh, around 1,200 m elevation, stay on the trail to protect the marsh plants, and wear shoes suited to muddy ground and changing weather.
In the forest, including the "Beech Flat" at about 1,300 m elevation, leaf colors, dappled sunlight, and the sound of the wind change with the season, creating memorable moments even when you are not taking photos.
Waterfall and Waterside Scenic Spots: Fukiware Falls, Lake Okushima, and Asama Otaki Falls
Waterfalls and lakes are appealing not only in summer but also during the seasons of fresh greenery and autumn foliage.
Because waterside paths can be slippery, follow posted signs, stay within permitted areas, and do not let photography distract you from safety.
Fukiware Falls: See the Sculpted Bedrock of Katashina Gorge
Fukiware Falls, on the Katashina River in Numata City, is one of Gunma's signature waterfalls, where water cascades over bedrock about 7 m high and 30 m wide.
Also called "the Niagara of the East," the area around the falls is a gray bedrock gorge known as Katashina Gorge (Fukiware Gorge), designated a National Natural Monument and Place of Scenic Beauty in 1936.
Viewing the falls head-on, from the side, and from a slightly distant angle from the trail and observation points reveals the way the water flows and the shapes of the rock.
Since the water volume and accessible areas are affected by season and weather, check the local guidance and don't step beyond the fences or ropes.
Lake Okushima: A Lakeside Stroll Around Shima Blue Waters
Lake Okushima is the reservoir of Shimagawa Dam, located beyond Shima Onsen in Nakanojo Town, and its cobalt-blue water is known as "Shima Blue."
The water's color changes with the weather, light, and season, and it often appears most vivid on clear mornings from April to May.
A road circles the lake for about 4 km. Stop at scenic overlooks and walk near the water to compare the shades of blue and reflections of the surrounding mountains.
Asama Otaki Falls: Enjoy the Sound of Water in the Forests of Naganohara and Kita-Karuizawa
Asama Otaki Falls is about 10 m high and 30 m wide, located on the Kuma River in the Kita-Karuizawa area of Naganohara Town. It is one of the largest waterfalls in the area.
A trail leads close to the base of the falls, where you can hear the rushing water and feel the cool forest air.
Spray near the falls can make the path wet and slippery, so wear slip-resistant shoes and protect your camera or smartphone.
Uodome-no-Taki Falls lies downstream. Include the surrounding forest and flowing water in your photos to capture the highland atmosphere.
Mount Myogi: One of Japan's Three Great Scenic Wonders
Mount Myogi is the collective name for a mountain range spanning Shimonita Town, Tomioka City, and Annaka City. Its sharp rock faces and dramatic form have earned it recognition as one of Japan's Three Great Scenic Wonders.
It is also one of the Jōmō Three Mountains alongside Mount Akagi and Mount Haruna. Travelers without climbing experience should enjoy it from viewpoints and easier walking routes rather than attempting the rocky trails.
Best Viewpoints for Mount Myogi's Jagged Silhouette
Mount Myogi is impressive both up close and from a distance, where its jagged outline stands out against the sky.
In the angled light of morning or evening, or as clouds drift past, shifting shadows add depth to the rock faces in photos.
If You Walk, Choose Your Route Carefully
Omote-Myogi has advanced traverse routes with chained sections such as Takamodoshi and Horikiri, so sightseeing travelers should choose a route suited to their fitness and experience.
Even on an easy route, wear sturdy walking or hiking shoes rather than casual footwear, and be prepared to turn back after rain or in strong winds.
Choosing Gunma's Scenic Spots by Season
Gunma's nature looks very different by season, even at the same place.
Changing the spots you choose depending on whether you prioritize flowers, greenery, autumn leaves, or snowscapes helps your trip come together.
From Spring to Summer, Enjoy Flowers and Waterside Scenery
From spring to summer, highlights include Oze's skunk cabbage (mid-May to early June), marsh plants at Kakumanbuchi and Tambara Highland, azaleas around Lake Nozori, and the waterside scenery of Fukiware Falls and Asama Otaki Falls.
Even in summer, weather can change quickly in highland and mountain areas, so carry a light jacket or rain gear.
From Autumn to Winter, Keep Autumn Leaves and Snowscapes in Mind
From mid-October to early November, Lake Haruna, Mount Myogi, Lake Okushima, and the Mount Akagi area offer striking combinations of autumn foliage, mountains, and water.
In winter, some places like Lake Nozori have road closures, so if snowscapes are your goal, check road and transport information before you set out.
Compare the Views by Season
Once your travel dates are set, choose destinations based on the scenery you most want to see to make the most of a limited schedule.
| Season | View | Candidates |
|---|---|---|
| Spring | Flowers & greenery | Oze & Akagi |
| Summer | Waterside & highland | Falls & Nozori |
| Autumn | Foliage & lakes | Haruna & Shima |
| Winter | Snow & stillness | Highlands & foothills |
Etiquette and Trip Preparation for International Travelers
At natural scenic spots, protecting the environment is just as important as enjoying the scenery.
In Japan's mountains and marshes, signs, entry restrictions, and trail rules differ by place, so prioritize the local signage.
Protect the Marshes and Alpine Plants
At places like Oze, Kakumanbuchi, and Tambara Marsh, the basic rule is to stay on the boardwalks and trails.
Not stepping on plants, not picking flowers, and checking local rules on whether drones or tripods are allowed all contribute to preserving the scenery.
At Waterside Spots, Mind Your Footing and Photo Position
Around waterfalls and lakes, wet rocks, mud, and fallen leaves can make footing slippery.
When taking photos, check behind you before stepping backward, stay within barriers, and avoid blocking other travelers.
Things to Check Before You Set Out
Mountain roads, ropeways, trails, and lakeside facilities may close or operate on limited schedules depending on the weather and season.
| Item to Check | Reason | Action |
|---|---|---|
| Weather | Conditions change quickly | Check before departure |
| Access | Seasonal closures | Check notices |
| Gear | Uneven or slippery ground | Wear suitable shoes |
| Photo rules | Protect nature | Read the signs |
Leave Room in Your Itinerary
On a Gunma nature trip, spending time watching the sky and water change at one location can leave a stronger impression than rushing from viewpoint to viewpoint.
Allow enough time to return to your hot spring town or station, and avoid driving mountain roads after dark whenever possible.
