Naganohara-machi, a town with abundant nature, is located in the northwestern part of Gunma prefecture. As a result of the completion of Yatsuba Dam in March 2020, a large lake was formed. In the vicinity of the lake, Kawarayu onsen camping site, barbecue facilities and amphibian bus are scheduled to open their services soon. The experience of these new facilities will be greatly enhanced by Mt. Asama, soaring magnificently to the south of the town, as it provides cool temperatures over the highland even in summer.
