Yubatake

Yubatake—literally a “hot-water field”—is the visual and practical centre of Kusatsu Onsen. Mineral-rich water emerges in clouds of steam, runs through wooden channels and cools before reaching the baths. This is more than a decorative spring: it shows part of the system that supports the hot-spring town. Lanes lead from its edges toward ryokan inns, public baths, shops selling manju and Netsunoyu, where visitors can see yumomi, the traditional paddle-stirring method used to cool water without diluting it.

The square is worth seeing at two different times. In daylight, the channels, stonework and steam reveal how the water is managed; after dark, lighting makes the steam part of the townscape. A walk of about 12 minutes along Sainokawara Street leads to the park and open-air bath. The route rises gently and may freeze in winter, so wear stable shoes and account for the walk back after bathing.

Public comments praise the evening lights, rising steam and chance to be in the middle of an onsen town without paying admission. Two qualifications recur: the mineral smell is intense for some visitors, and the landmark can feel like a quick stop if it is not combined with the baths and surrounding streets. This is an outdoor public space, not a pool or a place to enter the water. To understand it, watch the channels, read the names and pair the visit with a yumomi performance or a public bath.

Central Kusatsu is free to enter and remains accessible, although nearby shops and restaurants keep their own hours. The town’s tourism information lists +81 279-88-7188 for enquiries and provides transport guidance. Direct highway buses run from Tokyo, while a rail route reaches Naganohara-Kusatsuguchi before a local bus connection. In the centre, Yubatake, public baths and Sainokawara can all be reached on foot.
