Akagi refers to a hot-spring area on the slopes of Mount Akagi, a dormant volcano in Gunma Prefecture, in Japan's Kantō region north of Tokyo. The mountain's volcanic geology gives rise to onsen waters used for traditional Japanese bathing. Surrounded by a caldera lake and forested highlands, the area is a popular destination for soaking and nature outings.

Insider tip — Respect onsen etiquette: a shower is required before entering, soap is forbidden in the pools, and tattoos are often not accepted — check before your visit.
