basic information

Kusatsu has the largest natural flow of hot spring water in all of Japan, much of which surfaces at the yubatake in the town center. The sulfurous, highly acidic water has been considered among Japan's best for centuries, and has been lauded as a treatment for ailments that include arthritis, fatigue and skin disease among others.

The baths come in a variety of styles including stone, wood, indoor and outdoor types. And visitors to Kusatsu can enjoy them either at ryokan, or at public bath houses.

The ryokan baths are freely available to staying guests; however, many ryokan open their baths during the day to the general public as well, with an admission fee (typically 500-1000 yen).

Among the public bath houses located around Kusatsu, the larger ones with more baths and facilities, charge admission (typically 500-1000 yen). However, there are also eighteen communal baths across the town that consist of only one or two small (2-4 person) tubs and are free to use.

One of the most famous and popular public baths is Sainokawara Rotenburo, a large open air bath in Sainokawara Park. It has a nice mix of pleasant atmosphere, good water quality and beautiful scenery that makes for an excellent rotenburo experience.

Some bath houses offer a special bathing and medical treatment called jikanyu (lit. timed bath) where bathers bathe in extremely hot water (typically around 48 degrees Celsius) for about three minutes. The hot water's benefits include opening your pores and increasing blood flow within your body and to your brain.

Other bath related attractions in Kusatsu are the Onsen Museum on the third floor of the bus terminal, displaying the history of onsen and Kusatsu town, and the Yumomi, a traditional method of cooling down the hot spring water to bathing temperature that includes dancing and singing. Performances are held daily and can be viewed at Netsunoyu.
