Goshiki Onsen (Gunma)

Goshiki Onsen in Gunma Prefecture is a hot spring resort in the thermally active mountain zone of Gunma, one of Japan's most productive hot spring prefectures whose Kusatsu, Ikaho, and Shima onsens rank among the most famous in the country. The sulfated and simple waters of Goshiki Onsen, whose name meaning Five Colors reflects the visually striking character of its mineral springs, contribute to Gunma's exceptional thermal heritage in the volcanic mountains between Tokyo and the Niigata coast. Gunma's hot springs have been valued since antiquity within a long thermal tradition, and Goshiki Onsen continues this heritage in a prefecture whose thermal wealth has attracted bathers from across the Kanto region for centuries.
