Ohtaki no Yu

Otaki no Yu, one of the three main higaeri onsens of Kusatsu. Included in the corresponding pass. The star of the show is 4 baths, each hotter than the last. The final bath is a challenge — your reward is respect from the old-timers. The rotenburo is simply gorgeous (on the men's side) with a stone corridor waist-deep in water. There's also a sauna and a large regular bath. The water... this is Kusatsu. The water here is magical. Right now, with the snow falling, it's absolutely magical here.
