Kanra, in the hilly terrain of southwestern Gunma Prefecture, is an agricultural community in the Kabra River valley whose traditional silkworm cultivation heritage, connected to the Tomioka Silk Industry legacy, supported the mulberry farming landscape of the greater Gunma silk region that was instrumental in Japan's Meiji-era industrial transformation. Kanra Onsen Gunma draws on sodium and bicarbonate thermal waters from the geothermal resources of the southern Gunma highland zone, offering restorative baths in a rural community where the silk heritage farmhouse landscape, the traditional Gunma mountain vegetable cuisine, and the forested hillsides of the Kanra basin create a quietly authentic rural spa setting in the Gunma highlands. The traditional silkworm farmhouses of the Kanra hills, the nearby Tomioka Silk Mill UNESCO heritage accessible from the Kabra River road, and the mountain scenery of the western Gunma highlands bordering Nagano create a pleasant agricultural and heritage backdrop for thermal wellness in southwestern Gunma Prefecture.
