Ueno Village is a mountain village located at the southwestern tip of Gunma Prefecture. It borders both Nagano and Saitama prefectures and is surrounded by the rugged mountains of the region.
Excluding Tokyo’s outlying islands, Ueno is known as one of the least-populated municipalities in the Kanto region and has the smallest population of any municipality in Gunma Prefecture. Although its population is less than 1,000, more than 90% of the village’s total area is covered by forest.
With its abundant natural surroundings and the clear waters of the Kanna River flowing through the village, Ueno is a place that truly lives up to its reputation as a remote mountain retreat.
The area once belonged to the former province of Kōzuke, but the village name is pronounced “Ueno,” rather than “Kōzuke.” During Japan’s Heisei-era municipal mergers, Ueno declared that it would not merge with neighboring municipalities and chose to continue developing as an independent village.
Despite its remote mountain location and declining population, the completion of Ueno Dam and the Kanna River Power Station strengthened the village’s financial foundation and enabled it to continue its development as an independent municipality.
Ueno Village lies at elevations of approximately 450 meters and above, in a basin-like landscape surrounded on three sides by steep mountains ranging from about 1,000 to 1,500 meters in elevation.
Mount Osutaka, Mount Suwa, Mount Tenmaru, and Mount Takamagahara are among the mountains that surround the village. Mountain passes such as Jikkoku Pass and Budo Pass have historically served as routes connecting the former provinces of Shinshu and Joshu.
The Kanna River, which flows through the center of the village, is sometimes described as one of the clearest rivers in the Kanto region. Its exceptionally clean water and the efforts made to preserve the river environment earned it recognition as one of Japan’s “100 Remarkable Waters of the Heisei Era”, selected by the Ministry of the Environment.
The clear waters provide an ideal habitat for iwana char, yamame trout, and ayu sweetfish, making the river a popular destination for freshwater fishing.
Ueno has an inland climate with significant differences between daytime and nighttime temperatures. Summers are relatively cool, while winter can bring snow, although deep permanent snow cover is not common.
The four seasons are clearly defined. Fresh greenery appears in spring, lush forests dominate in summer, brilliant autumn foliage colors the mountains in fall, and winter brings quiet snowy landscapes and crisp, clear air.
Ueno has a long history. During the Edo period, several villages existed in the area under the administration of regional officials. The modern municipality of Ueno Village was established in 1889 with the introduction of Japan’s modern municipal system.
In 1884, the effects of the Chichibu Incident reached the area, and an uprising also took place within the village, linking Ueno with an important episode in Japan’s modern history.
On August 12, 1985, Japan Airlines Flight 123 crashed on the Osutaka Ridge in Ueno Village in one of the world’s deadliest aviation disasters involving a single aircraft. The tragedy remains deeply embedded in the history of the village, and memorial and remembrance activities continue today.
In more recent years, roads and tunnels have been improved. The opening of the Yunosawa Tunnel in 2004 significantly improved access from the Shimonita Interchange of the Joshinetsu Expressway, making the remote village more accessible to visitors.
Fuji Cave, located within Kawawa Nature Park, is one of the largest limestone caves in the Kanto region, extending for approximately 2.2 kilometers.
Stalactites and stalagmites formed over immense periods of time create a mysterious underground world that resembles a natural palace beneath the earth.
Parts of the cave have been developed for visitors, allowing them to enjoy an adventurous exploration while experiencing the remarkable power of nature.
The Ueno Sky Bridge is a massive suspension bridge connecting Kawawa Nature Park with Mahoba no Mori. It is approximately 225 meters long and 90 meters above the ground.
Every 30 minutes, soap bubbles are released into the air, creating a magical scene against the blue sky.
From the bridge, visitors can enjoy panoramic views of Oku-Kanna Lake and the surrounding mountains. The scenery changes beautifully with the seasons, making the bridge an especially memorable place for photography.
Mahoba no Mori is a resort area equipped with cottages, a restaurant, barbecue facilities, and a variety of outdoor activities.
Visitors can enjoy camping, forest walks, and athletic activities surrounded by trees. At Forest Adventure Ueno, visitors can take on full-scale outdoor adventure courses and experience the thrill of moving through the forest.
The activities are suitable for both children and adults, making the area a popular destination for families and outdoor enthusiasts.
Oku-Kanna Lake was created by Ueno Dam, one of the tallest dams in the Tone River system. Surrounded by mountains, the tranquil lake reflects the changing colors of the seasons.
The peaceful scenery is particularly popular with photographers and visitors seeking a quiet escape into nature.
The Ueno Village Hot Spring Area includes facilities such as Hampei Hot Spring “Shioji no Yu” and Mukōya Hot Spring “Villa Seseragi.”
The mineral-rich water contains a relatively high concentration of metasilicic acid and is sometimes referred to as a “beauty bath.” Its smooth, gentle texture is particularly pleasant on the skin.
Relaxing in an open-air bath surrounded by mountains while listening to the sound of a nearby stream offers a peaceful way to unwind after exploring the village.
Traditional events are held throughout the year in Ueno Village. These include Ohinagayu, selected as an Important Intangible Folk Cultural Property by the national government, and Okawase-sage, designated as an Important Intangible Folk Cultural Property by Gunma Prefecture.
These festivals preserve local beliefs, traditions, and stories that have been passed down through generations.
Another important cultural site is the Former Kurosawa Residence, a nationally designated Important Cultural Property. The traditional thatched-roof residence provides a valuable glimpse into the lifestyle of a village headman-class family during the Edo period.
Its substantial traditional architecture offers visitors a sense of the history and everyday culture of mountain communities in premodern Japan.
Ueno Village has been recognized as a Forest Therapy Base, where visitors can enjoy walks through forests that have been studied for their relaxing effects.
Facilities such as the Forest Science Museum “mori+” and the Nature Experience Learning House “Komorebi” provide opportunities for environmental education, nature activities, and overnight educational programs.
These facilities are also used for school field trips and educational programs, allowing visitors to learn about forests and the natural environment through hands-on experiences.
One of Ueno’s best-known local specialties is inobuta cuisine, made from a cross between wild boar and domestic pig.
The meat combines the rich flavor of lean meat with the gentle sweetness of its fat, creating a distinctive balance.
Other local dishes include grilled ayu sweetfish and yamame trout caught or raised in the clear waters of the Kanna River, as well as Gunma specialties such as udon and soba noodles.
These simple, hearty dishes reflect the ingredients and food culture of the surrounding mountains.
Popular local products include naturally brewed Jikkoku Miso, thick and meaty locally grown shiitake mushrooms, and traditional woodcraft products, making them attractive souvenirs of a visit to Ueno.
Ueno offers a variety of accommodation options, from long-established inns such as Imaiya Ryokan and traditional guesthouses to cottages and glamping facilities at Mahoba no Mori.
Spending a night surrounded by forests and the clear Kanna River offers a level of peace and quiet that is difficult to experience in a city.
On clear nights, the beauty of the star-filled sky provides another memorable highlight of staying in this remote mountain village.
In spring, cherry blossoms and azaleas add color to the mountain landscape. Summer is ideal for playing in the clear streams and enjoying camping, while autumn brings brilliant foliage across the mountains.
Winter offers crisp, clear air and quiet snowy scenery. With more than 90% of the village covered by forest, Ueno provides a rich natural environment that offers visitors a chance to relax and reconnect with nature throughout the year.
Ueno Village is a special destination where nature, history, traditional culture, and the warmth of the local community come together.
Its small population and remote location have helped preserve a slower pace of life and a rich natural environment. From limestone caves and suspension bridges to hot springs, forests, clear streams, traditional festivals, and mountain cuisine, the village offers many ways to experience rural Japan.
For travelers looking to escape the bustle of the city and spend time surrounded by mountains and pristine nature, Ueno Village offers a peaceful and memorable journey into the heart of southwestern Gunma.
