Yuyado Tokinoniwa

Every guest room here has its own open-air bath fed by Kusatsu's spring water, so the soak is part of the room rather than a trip down the hall. The large shared baths add a rotenburo and an indoor bath on each side (men's and women's swap between two setups through the day), a sauna, and paired hot and cool tubs side by side. Three small kashikiri baths are free and open on a walk-in basis, no booking needed. There is also a ganbanyoku stone-bed sauna alongside the regular bathing areas. The inn sits above Kusatsu's hot-spring town, with a shuttle running down to the yubatake.
