Midori, in the eastern Gunma Prefecture bordering Tochigi and Saitama, is a post-merger city incorporating several former communities in the lower reaches of the Watara River zone, set in the transition zone between the Kanto mountains and the broader Kanto plain where traditional Gunma silk farming landscapes blend with the suburban fringe of the greater metropolitan region. Midori Onsen Gunma draws on sodium and bicarbonate thermal waters from the geothermal resources of the eastern Gunma zone, offering restorative baths in a community that preserves elements of the traditional Gunma agricultural and silk heritage landscape on the western approaches to the Kanto plain. The Kiryugawa River valley cycling paths, the traditional silk weaving heritage of the greater Kiryushi area adjacent to Midori, and the mountain scenery of the eastern Gunma borderlands with Tochigi and Saitama create a pleasantly varied spa destination on the eastern edge of Gunma Prefecture.
