Akakura Onsen Notenburo (Taki no Yu) sits in Myōkō, Niigata Prefecture, a mountainous region of Japan known for its hot spring resorts. The sulfurous water emerges at 44°C, pH 6.5. The site offers an indoor bath, an outdoor rotenburo bath and a sauna, in a setting typical of Japanese mountain onsen.
Insider tip — Akakura Onsen at the foot of volcanic Myokosan has been a ski resort and hot spring destination since the 1930s, pioneering Western-style alpine tourism in Japan. The Taki no Yu waterfall open-air bath sits amid snowfields in winter and azalea forests in spring, making it one of Niigata most photogenic outdoor soaking experiences.
