Kuroyu Onsen

Kuroyu sits 800 meters up the road from Tsurunoyu in a clearing where the spring source runs at near-boiling temperature; staff route the water through the village's wooden pipes to four separate baths, each cooler than the last. The two thatched-roof bath buildings are originals from 1764. Closed November through April for snow. The day-soak fee is the lowest of the Nyuto seven.
