湯畑36°37′ N 138°36′ EOnsen townFree
Kusatsu Onsen's Yubatake is the free, steaming centre of the town and the source that feeds the inns around it, and the locals' free public baths a few steps away suit visitors who can take very hot, very acidic water with nothing but a tub and a tap.

Know before you bathe
The public baths are the residents' own, kept by the people who use them daily. Wash before you get in, and ask before you cool a tub with the tap.
Getting there
The Yubatake is about five minutes' walk downhill from Kusatsu Onsen Bus Terminal. Shirahata-no-yu stands on its edge, Chiyo-no-yu is two minutes away and Jizo-no-yu three.
The Yubatake is a long bed of wooden channels in the middle of Kusatsu where the hottest water in town runs out to cool before it reaches the inns. Tiled paths and stone railings run round it, and a cypress pavilion called Yukemuri-tei on one side rebuilds an Edo-period public bath, with a free foot bath and a basin for your hands.
Shirahata-no-yu, the biggest of the free public baths, sits on the edge of the Yubatake and draws from the Shirahata source. Chiyo-no-yu, two minutes away, keeps a separate room for the old Kusatsu bathing method beside its men's and women's tubs. Jizo-no-yu, three minutes off, runs slightly cloudy water from the Jizo source. These baths have no locking lockers and close for cleaning for part of each day.
JMA's account of the volcano lists Kusatsu's many fumaroles and hot springs among its features, and JMA keeps Kusatsu-Shirane under 24-hour watch, with two separate alert scales for the Yugama crater and for Motoshirane, and the town's own notices set what is open on the summit road. In winter the Shiga-Kusatsu road over the top closes from mid-November, and the summit area shuts with it.
Worth knowing
- Chiyo-no-yu opens at 6:00 and Shirahata-no-yu at 8:00, so an early bath fits in before breakfast.
- Buy the three-bath pass for ¥2,100 if you plan to use Otaki-no-yu, Gozanoyu and Sai-no-kawara; it has no expiry date.
