Kusatsu Onsen
Kusatsu Onsen - An Unexpected Love Affair
In fact, Kusatsu Onsen is more than just another hot spring spot—it’s one of Japan’s most iconic and beloved getaways. Time and again, it ranks at the top of national onsen lists, and once you’re there, it’s easy to understand why. Picture this: clouds of steam curling through charming streets, old-fashioned ryokan with creaky floors and paper walls, and mineral-rich waters so healing that they’ve been praised for centuries.
The whole town feels like it’s been lifted from a timeless postcard. There’s an atmosphere here that’s hard to describe—equal parts soothing and slightly surreal. Even the scent of sulfur in the air feels like part of the welcome.
Some say, “You haven’t really experienced Japan until you’ve soaked in Kusatsu’s famous waters.” And honestly? They’re not wrong. Whether you come for the healing properties, the nostalgia, or simply to slow down, Kusatsu has a way of leaving a mark.





Explore Kusatsu’s Living Culture and Timeless Traditions



For generations, people have been drawn to Kusatsu not just for its breathtaking scenery, but for its legendary hot spring water. Renowned for its powerful acidity, Kusatsu’s springs are said to ease fatigue, treat skin conditions, and leave bathers feeling refreshed from the inside out.
But Kusatsu is more than just what you soak in—it’s also what you experience. Take the famous “Yumomi” performance, for example. Local women in traditional outfits rhythmically stir the scalding water using large wooden paddles, all while singing cheerful folk songs. It’s part show, part ritual, and 100% unforgettable.
There’s something heartwarming about it—watching generations preserve this quirky custom with such joy. It’s not just entertainment; it’s cultural memory passed on in every splash and song.
