Nihongi no Yu

Overview

Nihongi no Yu is a unique hot spring facility located in Kiso, Nagano Prefecture, not far from the Kisofukushima ski area. This onsen is known for its natural carbonated spring water, which has a reddish-brown color due to its iron content and creates tiny bubbles that cling to the skin. The facility offers indoor baths only, with a cozy, traditional atmosphere. The small bathing area and simple amenities provide a relaxing experience, especially after a day of skiing or exploring the Kiso region. There is also a relaxation area with a dining space where visitors can unwind and enjoy a meal. Open year-round, it's a great place to experience a traditional Japanese onsen.
