Kusatsu Onsen

Rising from a highland in the northwest of Gunma, Kusatsu Onsen is counted among the three most celebrated hot springs in Japan. At the center of town lies the Yubatake, where steam endlessly billows into the air, forming the very symbol of Kusatsu. Its strongly acidic water has a powerful cleansing quality and has been cherished by visitors for centuries.

Highlights

The Yubatake, the emblem of Kusatsu, channels hot spring water down wooden troughs in a striking terraced design, and at night it is illuminated into a dreamlike scene. At the Netsunoyu hall you can watch the traditional practice of yumomi, where hot spring water is stirred with wooden paddles to cool it, accompanied by spirited local folk songs. Wander the streets and the scent of the springs fills the air, drawing you toward a leisurely bath-hopping mood.

Enjoying the Seasons

As a highland town, the change of seasons is vivid here. Summer offers cool relief as a mountain retreat, while autumn paints the surrounding peaks in brilliant foliage. In winter, steam rises against a snowy backdrop for a memorable snow-viewing soak. Spring brings fresh greenery, and every season reveals a different face of the town.

Access and Basic Information

By car, you take mountain roads from the Shibukawa Ikaho interchange on the Kanetsu Expressway. By public transport, it is convenient to ride a bus from Naganohara Kusatsuguchi Station on the JR Agatsuma Line. Public bathhouses are scattered through the town, and inns and souvenir shops cluster around the Yubatake.

A Quick Tip

Because the water is strongly acidic, it is best to keep each bath short and enter several times rather than soaking for long. Those with sensitive skin may wish to rinse lightly with fresh water afterward. Mornings and evenings can be chilly in the highlands, so carry a light layer even in summer.
