| Facility | Spring | Source data | Supply | Bath type |
|---|---|---|---|---|
| Kurodake-no-Yu, Sounkyo Onsen | Natural hot spring. The current tourism page describes it as low-salinity, mildly alkaline and hot; an up-to-date facility-specific chemical analysis is not available. Source: Sounkyo Onsen; the current official text page does not publish the individual spring name used by Kurodake-no-Yu. | Source temperature: Not published. pH: Not published in the current material summarized here. | Kamikawa Town lists this municipal day-use facility with indoor and open-air baths, sauna and cold bath, and the facility describes itself as a 100% natural public hot spring. The current 2026 pages do not publish water addition, heating, circulation or disinfection for each pool. | Day-use bath. A practical reference point after the Kurodake Ropeway or a hike, with low admission, a sauna, open-air bath and nearby transport. |
| Hotel Taisetsu ONSEN & CANYON RESORT (Day-Use Onsen) | Simple sulfur spring Source: The spring used by Hotel Taisetsu; the current official pages do not publish an individual spring name or exact source temperature | Source temperature: Not published; the hotel describes the source water as high-temperature pH: Not published | The hotel says all its baths are free-flowing, with no recirculation. Water is added to bring the high-temperature spring to a usable temperature. The property has three large bath areas and two outdoor baths, with lookout, gorge-side and European-style settings. | Ryokan. For a day visit to Sounkyo, Hotel Taisetsu makes sense when the gorge views and choice of baths matter more than price. Its elevated lookout and several bath areas are the draw. |
| Sounkyo Choyotei (Day-Use Onsen) | Simple spring, hydrogen sulfide type (neutral, low-tonicity, high-temperature spring) Source: The spring used by Choyotei | Source temperature: 68°C pH: 7.5 | The source temperature is 68°C. The hotel has a seventh-floor Sky Garden open-air bath and panoramic bath, plus the second-floor Iyashi-no-Yu area. For the Sky Garden baths, the hotel lists water addition, heating, recirculation and chlorine disinfection; the large bath is listed separately as water-added and free-flowing. | Ryokan. At ¥1,200, Choyotei is a mid-priced pick for its sky-level outdoor bath and views of Sounkyo's columnar cliffs. Call first, since day-use admission is not always available. |
