Sainokawara Park (̉͌, Sainokawara Kōen) covers a valley not far from Kusatsu town center, where several hot spring sources and a large outdoor bath are located. Walking trails around the upper part of the park lead through the nice natural landscapes.

Hot spring water can be seen bubbling to the surface here and there, collecting into hot water pools and running down the valley in warm streams before joining the central mountain stream. There is also a small waterfall fed by hot water.

The park's other main attraction is the Sainokawara Rotemburo, consisting of two large, gender separated outdoor hot spring pools with a capacity of 100 bathers each.

Getting there and around

Sainokawara Park is a ten minute walk from the yubatake along a narrow road lined by numerous ryokan and shops.
