Located near the iconic Yubatake in the heart of Kusatsu Onsen, Netsunoyu is a cultural center where you can witness and experience the traditional art of "Yumomi." Yumomi is the practice of using large wooden boards to stir the extremely hot spring water to lower its temperature. Far more than just a practical task, it is a vital piece of local wisdom and a captivating form of entertainment that has been passed down through generations.
The highlight of Netsunoyu is the "Yumomi and Dance" show. The energetic performance, blending rhythmic stirring with traditional dance, is a spectacle that transcends language- barriers and captivates visitors from around the world. Beyond just watching, you can also participate in a hands-on program to try the Yumomi technique yourself, offering a truly tactile way to connect with the spirit of Kusatsu.
Kusatsu Onsen has long been celebrated as one of Japan's premier hot spring destinations. However, the natural spring water is so hot that it is difficult to bathe in immediately. To manage this, locals developed the technique of "Yumomi," using large wooden paddles to stir the surface of the water, cooling it down and stabilizing its mineral components through contact with the air.
Over many years, this process evolved from a necessary cooling method into a celebrated traditional performing art. Netsunоyu serves as a hub to preserve this history, ensuring that the culture of Kusatsu is shared with the next generation and travelers from across the globe.

The main event at Netsunoyu is the "Yumomi and Dance" show. Performers dressed in traditional attire stir the water with dynamic, rhythmic movements that are incredibly powerful to watch. The accompanying dances bring the lively atmosphere of Kusatsu to life, making it a must-see event.
Additionally, the facility features exhibits that explain the history and mechanics of Yumomi, allowing you to gain a deeper understanding of how Kusatsu Onsen has maintained its legendary waters. The vibrant energy of the entire facility is part of the charm that makes every visit memorable.
Since shows are held at regular intervals throughout the day, it is most efficient to stop by while exploring the Kusatsu Onsen area.
While enjoyable in any season, watching the steam rise during a winter visit adds a particularly cozy and atmospheric touch to the experience.
