Located at the top of Ikaho Onsen, Ikaho Onsen Rotenburo offers a unique outdoor bathing experience. This public bath features two types of hot spring water: one hot and one lukewarm, both sourced directly from the spring. Note that there are no showers, so visitors simply rinse before entering the baths. Open from 9 AM to 7 PM (10 AM to 6 PM from October to March), and closed on the 1st and 3rd Thursdays of the month (open if a holiday), it's an ideal spot to relax and enjoy the natural surroundings. You can purchase a towel at the entrance if needed.
