Spacious Outdoor Baths
Wataze Onsen is a beautiful hot spring featuring the largest Rotenburo open-air hot spring bath in all of western Japan. It is a little confusing because the main lodging facility is called Watarase Onsen, the name most commonly used. Watching the moon rise over the mountains as you soak in this gorgeous setting is an experience that you will never forget. It is famous for its private Rotenburo open-air baths for couples, families or groups. The hot spring “Kuwahausu Hongu” has a large volume of high-quality water and offers eight different types of baths. There are rental bungalows and a campground close by.
