Kawaji Onsen Yakushi-no-yu
The communal bath of Kawaji Onsen, upstream of Kinugawa on the clear Ojika River. An old cure spa — 'burns to Kinugawa, wounds to Kawaji' went the saying — it uses its own mildly alkaline spring 100% free-flowing with no chlorination. Besides separate indoor and open-air baths there is a mixed rock bath open to the river, where you soak in lukewarm water facing the stream and hills (bathing garments allowed). A low-temperature sauna, private bath (¥4,000 / 50 min) and rest room complete it. Adults pay ¥1,000 (¥500 for Nikkō residents); open 10:00–20:00 (last entry 19:30), closed Wednesdays (next day if a holiday; open through Golden Week). Fifteen minutes on foot from Kawaji-Yumoto Station on the Yagan Railway, or about 15 minutes by car from Kinugawa-Onsen Station — easy to combine with Kinugawa.
