Discover Kusatsu Onsen: Japan’s Renowned Hot Spring Resort
Nestled in the mountains of Gunma Prefecture, Kusatsu Onsen (草津温泉) is one of Japan’s most famous hot spring resorts, celebrated for its natural healing waters and rich cultural heritage. Known for its therapeutic benefits, breathtaking scenery, and charming town atmosphere, Kusatsu Onsen offers an unforgettable experience for both relaxation and exploration.
The Healing Waters of Kusatsu Onsen
Kusatsu Onsen’s hot springs are renowned for their high acidity and rich mineral content, which are said to help alleviate various ailments, including muscle pain, fatigue, and skin conditions. The water originates from the nearby Mount Kusatsu-Shirane, a volcanic mountain that continuously supplies the area with fresh thermal water. This natural resource has earned Kusatsu Onsen a reputation as one of Japan’s top three onsens, alongside Gero Onsen and Arima Onsen.
Yubatake: The Heart of Kusatsu Onsen
At the center of the town lies Yubatake (湯畑), or “hot water field,” which is a symbol of Kusatsu Onsen. This large, open-air structure is where hot spring water flows through wooden channels, cooling naturally before being distributed to local ryokan (traditional inns) and public baths. The sight of steam rising from the Yubatake, especially at night when illuminated, creates a magical atmosphere that captivates visitors.
Traditional Bathing Culture
Experiencing the local bathing culture is a must when visiting Kusatsu Onsen. There are numerous public baths, known as sento and onsen ryokan, where visitors can soak in the mineral-rich waters. Among the most popular are:
- Sainokawara Rotenburo: An open-air bath located in Sainokawara Park, surrounded by nature, offering a tranquil bathing experience.
- Otaki-no-Yu: Famous for its cascading waterfall baths, where the water gently massages the body.
- Gozanoyu: A beautifully restored traditional bathhouse with wooden interiors, providing an authentic Japanese onsen experience.
Unique Cultural Experiences
In addition to bathing, visitors can witness yumomi (湯もみ), a traditional water-cooling performance where local women stir the hot spring water with large wooden paddles while singing folk songs. This practice, dating back centuries, was developed to cool the water without diluting its mineral properties and is now a popular cultural show held at the Netsu-no-Yu theater.
Exploring the Town and Nature
Beyond its hot springs, Kusatsu Onsen is surrounded by beautiful natural landscapes. Sainokawara Park offers scenic walking trails and foot baths, while Mount Kusatsu-Shirane provides hiking opportunities and stunning views. In winter, Kusatsu transforms into a ski resort, attracting snow sports enthusiasts from across Japan and beyond.
How to Get There
Kusatsu Onsen is accessible by train and bus from Tokyo. The most convenient route is to take the JR Limited Express Kusatsu from Ueno Station to Naganohara-Kusatsuguchi Station, followed by a 30-minute bus ride to the onsen town. For those seeking a scenic journey, driving through the mountains is also an excellent option.
