The hot spring resort town of Kusatsu Onsen sits nestled in the mountains of Gunma Prefecture. Small, but always bustling with visitors, the town is famed for its spas, winning top rankings in travel surveys every year.
Kusatsu Onsen receives the highest volume of free-flowing hot spring water in Japan. Every spa uses 100 percent natural spring water, sourced piping hot from the active volcano Mt. Shirane. The quality of the therapeutic water, high in acidity with strong antibacterial properties, has drawn visitors from afar for centuries, including samurai warriors seeking relaxation during the Muromachi period (1336–1573).
Today, the town’s hot spring spas run the gamut from beautiful traditional wooden-clad spas to a modern resort-style themed spa. Other attractions include outdoor spas, foot baths, and public bathhouses.
