Kohan no Yu, by a lakeside in Tsumagoi, Gunma Prefecture, uses sulfurous water at 44°C. Guests can use an indoor bath, an outdoor rotenburo and a sauna at this lakefront hot-spring facility.
Insider tip — Kohan no Yu, the lakeside spring, serves the Baragi lake district of the Tsumagoi highlands in Gunma at the foot of the Asama volcanic zone where Mount Asama (2,568m) — Japan most continuously active volcano — provides the geothermal heat driving the sulfurous springs. The Baragi Plateau at 1,300 metres is one of Japan premier highland agricultural areas where Gunma cabbage and lettuce cultivation in cool mountain farms supplies Tokyo supermarkets year-round, and the Baragikohan lake mirrors the forested volcanic ridgeline in extraordinary mountain clarity.
