Minakami Town is the northernmost municipality in Gunma Prefecture, located in Tone District along the border with Niigata Prefecture, known as the Jōetsu Border. It is the largest municipality in Gunma by area, with extensive forests covering much of its territory.
The landscape ranges from satoyama foothills at around 300 meters above sea level to towering peaks reaching more than 2,000 meters. The town spreads across the southern side of the Mikuni Mountains, part of the central watershed of Japan.
Minakami has developed historically as an important transportation hub, a destination for hot-spring retreats, and a center of mountain worship. The clear Tone River flows from north to south through the center of the town, while its headwaters form an important ecosystem recognized as the Minakami UNESCO Biosphere Reserve.
Since its designation in 2017, the area has attracted attention in Japan and abroad as a model region where nature and human communities coexist.
Minakami is surrounded by some of Japan’s best-known mountains, including Mount Tanigawa, Mount Tairappyo, Mount Sennokura, Mount Hotaka, and Mount Shibutsu. Among them, Mount Tanigawa is an iconic destination, particularly popular because it is relatively accessible from the Tokyo metropolitan area.
The Tone River and its tributaries, including the Akaya River and Yubiso River, support the area’s rich natural environment and local industries.
The town is also home to several major dams, including Yagisawa Dam and Lake Okutone, Naramata Dam and Lake Naramata, and Fujiwara Dam. These reservoirs play an important role in supplying water to the Tokyo metropolitan area while also creating scenic destinations for visitors.
Despite its mountainous setting, Minakami has strong transportation links with the major cities of Japan. The Jōetsu Shinkansen, JR Jōetsu Line, Kan-Etsu Expressway, and National Route 17 run through the area, making it relatively easy to reach from the Tokyo metropolitan region.
The opening of railways from the Meiji period onward greatly accelerated the development of the area. In 1931, the Jōetsu Line was completed, creating an important railway connection between the Kanto and Niigata regions through the Shimizu Tunnel.
In 1982, the Jōetsu Shinkansen began operation, and Jōmō-Kōgen Station opened in Minakami. This dramatically improved access from the Tokyo metropolitan area.
From the 1950s onward, numerous dams were constructed along the Tone River system. Yagisawa Dam and Naramata Dam became important components of the metropolitan water supply, while the lakes created by the dams also developed into scenic attractions.
Doai Station on the JR Jōetsu Line is famously known as the “Mole Station.” The lower platform is located deep underground, and passengers must descend a remarkably long staircase of 462 steps.
With its secluded atmosphere and unusual underground platform, Doai Station has become a distinctive attraction for railway enthusiasts and travelers looking for an unusual experience.
In 2017, the region including Minakami was designated as the Minakami UNESCO Biosphere Reserve. The area’s mountain landscapes, extensive forests, clear rivers, and diverse ecosystems have received international recognition.
Each season brings a different landscape, from fresh green foliage in spring and alpine plants in summer to brilliant autumn colors and deep winter snow.
Mount Tanigawa, one of Japan’s celebrated 100 Famous Mountains, is especially popular. Visitors can take a ropeway to Tenjindaira, making it possible to enjoy spectacular mountain scenery even without undertaking a full mountain climb.
The Tanigawadake Ropeway provides an aerial journey to Tenjindaira at approximately 1,300 meters above sea level.
The scenery changes dramatically with the seasons. Alpine plants can be seen from spring through summer, autumn brings colorful foliage, and winter covers the mountain in high-quality powder snow.
Because visitors can enjoy impressive mountain scenery without a strenuous climb, the area is also accessible to travelers who do not normally hike or climb mountains.
Ichinokurasawa is renowned for its dramatic rock walls and is counted among Japan’s three great rock faces. The sheer cliffs create an impressive landscape that is particularly popular with photographers.
Walking trails provide opportunities to experience the scale of the surrounding mountains at close range.
The highland areas of Minakami Kogen and Hōdaigi are popular summer retreats. During the warmer months, visitors can enjoy hiking, camping, and the refreshing mountain air, while winter brings skiing and snowboarding.
The expansive landscapes and clear air offer a sense of openness that is difficult to experience in urban areas.
Fujiwara Dam is an important facility on the Tone River system. Nearby Lake Dōgen offers peaceful lakeside scenery and is especially attractive during the fresh greenery of spring and the colorful foliage of autumn.
The area is also popular for scenic drives and outdoor activities such as fishing and canoeing.
Lake Naramata, formed by Naramata Dam, is known for its striking emerald-green water.
Water activities such as kayaking and stand-up paddleboarding (SUP) are popular, while walking trails around the lake provide a more leisurely way to enjoy the surrounding nature.
Minakami has an inland climate with significant differences between summer and winter. The area is particularly well known for its heavy snowfall. Annual snowfall can exceed 1,000 centimeters in some areas, and winter temperatures can occasionally fall below -10°C.
Although winter can be severe, the resulting snow-covered landscapes are one of Minakami’s major attractions.
Spring greenery, lush summer forests, brilliant autumn foliage, and snowy winter scenery provide distinctly different experiences throughout the year. Because of the town’s considerable differences in elevation, the timing of seasonal changes varies from one area to another.
Evidence of human settlement in the Minakami area dates back to the Jōmon period. Important archaeological sites, including the Yaze Site and the Minakami Stone Age Dwelling Site, remain today.
During the medieval period, the Mikuni Kaidō highway was developed as an important route connecting the provinces of Kōzuke and Echigo, making Minakami a significant transportation hub.
The area also played a role during the Warring States period. Najigumo Castle is associated with the Sanada clan and is historically connected with the events that led to Toyotomi Hideyoshi’s campaign against the Later Hōjō clan.
The Minakami Stone Age Dwelling Site is a group of pit dwellings dating from the middle to late Jōmon period. It was designated a National Historic Site in 1944.
The site features distinctive structures in which river stones were arranged around hearths, providing valuable evidence of daily life in prehistoric Japan.
The Yaze Site, also designated a National Historic Site, contains archaeological remains including stone arrangements believed to provide clues about ancient settlements and ritual practices.
Together, these sites demonstrate the long-standing importance of the Tone River basin as a place for human settlement.
The Mikuni Kaidō became an important route linking Kōzuke and Echigo during the medieval period. During the Warring States period, Uesugi Kenshin crossed the Mikuni Pass while advancing into the Kanto region, and the Tone area subsequently came under the influence of various powerful warlords.
The Sanada clan later governed the region from Numata Castle.
One of the best-known historical sites is Najigumo Castle. The Najigumo Castle Incident of 1590 was one of the events associated with Toyotomi Hideyoshi’s campaign against the Later Hōjō clan.
Today, the castle site is preserved as a historic landmark, with an information center displaying historical materials. From the ruins, visitors can also enjoy views across the Tone River valley.

The area also hosts the music festival New Acoustic Camp, where visitors can enjoy live music surrounded by nature. The event represents a contemporary style of tourism that combines outdoor recreation and music.
As the source region of the Tone River, Minakami plays an important role in supplying water to the Tokyo metropolitan area.
Its extensive forests and clean mountain waters are among the town’s most valuable natural assets. Hot springs, outdoor activities, history, culture, and agriculture have all developed in close connection with this natural environment.
While tourism is one of Minakami’s key industries, the town also places importance on environmental conservation and sustainable agriculture.
