Kusatsu

Kusatsu is one of Japan's best-known onsen towns. Ryokan inns dot this quaint area, which retains an authentic Japanese atmosphere. At the town's center is the Yubatake, its spring source, which emits large quantities of steaming hot, mineral-rich water. Catch yumomi, a ceremonial water-stirring performance, at Netsunoyu, right next to Yubatake. Don a traditional yukata robe and enjoy onsen hopping among the picturesque townscape or the outdoor baths at nearby Sainokawara Park. Alternatively, break from bathing and hike the spectacular mountains and natural scenery surrounding Kusatsu or, in winter, take to the ski slopes.

See & Do

Relaxation

Kusatsu Onsen

Kusatsu Onsen is centered around the Yubatake, the source of most of the area’s onsen water. Its rising steam adds a dose of magic to the town's traditional atmosphere—especially at night, when the Yubatake is lit up to spectacular effect. Bathe at rustic bathhouses, luxe ryokan inns, and stunning rotenburo (outdoor baths), or stroll the town's charming streets.

Nature & Outdoors

Yoshigadaira Wetlands

The Yoshigadaira Wetlands are part of Joshin'etsukogen National Park and are located on the northeastern side of Mt. Kusatsu-Shirane, an active volcano. This scenic spot blooms with cottongrass in summer, while in autumn, Erman's birch trees turn a bold yellow. The contrast of the lush wetlands under the gaze of the stark volcano is striking, making for a photogenic hiking route.

Action & Adventure

Kusatsu Onsen Ski Resort

Spend a day on the slopes of Mt. Kusatsu-Shirane at Kusatsu Onsen Ski Resort before soaking away those aches in Kusatsu’s natural hot springs. This small resort has courses for beginner and intermediate skiers and snowboarders. The resort is usually open from the end of December to the end of March.

History & Culture

Netsunoyu

Kusatsu's spring water gushes from the source at a temperature too hot for bathing. A water-stirring ceremony, called yumomi, cools the water naturally. A team uses wooden boards to carry out a synchronized song and dance performance while rhythmically churning the water. Watch the ceremony or try water stirring for yourself at Netsunoyu, next to Yubatake, for an insight into Kusatsu's culture.

Relaxation

Manza Onsen

Manza Onsen is a hot spring village located 1,800 meters up Mt. Kusatsu-Shirane, near the town of Kusatsu. Its milky white, sulfuric water is prized for its purported health benefits. Try some of Manza’s open-air baths (rotenburo), where you can soak up the minerals while enjoying the mountain views.
