Minakami UNESCO Biosphere Reserve and Environmental Conservation
In 2017, Minakami Town was designated as a UNESCO Biosphere Reserve. The town has been promoting initiatives that balance environmental conservation with sustainable tourism.
The forests and clear streams around the headwaters of the Tone River are particularly important because the region serves as a major water source for the Tokyo metropolitan area.
Minakami Onsen-kyo has developed while maintaining a close relationship with its natural environment. Today, the area continues to welcome visitors while working to preserve its natural landscapes, culture, and history for future generations.
A History of Development and Revitalization
The opening of the entire Joetsu Line in 1931 dramatically improved access from the Tokyo metropolitan area and contributed greatly to the development of Minakami as a tourist destination.
The area subsequently continued to grow with the opening of ropeways, dam construction, and the development of other tourism infrastructure.
At the same time, the region has experienced difficulties, including fires and issues concerning hot spring labeling. Today, efforts are being made to reorganize abandoned facilities and revitalize the traditional hot spring towns through landscape improvements and efforts to attract new investment.
The area’s designation as the Minakami UNESCO Biosphere Reserve in 2017 has further strengthened its identity as a tourism destination that seeks to coexist with nature.

The hot springs of Minakami are more than places to bathe. They represent a rich regional heritage shaped by mountain worship, literature, transportation history, tourism culture, and traditional ways of life.
Combining a hot spring stay with Mount Tanigawa hiking, skiing, rafting, canyon walks, and other outdoor activities allows visitors to experience the region from many different perspectives.
With its beautiful natural surroundings, fascinating history, and ongoing efforts toward revitalization, Minakami Onsen-kyo continues to evolve while preserving the character of a traditional mountain hot spring destination.
