Onsen and Wellness
The baths at Hotel Oosado offer something rare—direct views of the Sea of Japan as you soak. Step into the open-air baths and watch the sunset melt into the waves, or gaze at the twinkling fishing lights offshore. Both the men’s and women’s baths have saunas and indoor baths as well.
The spring water at Kasugasaki Onsen is a sodium calcium chloride sulfate spring. It soothes fatigue, muscle pain, neuralgia, and helps with circulation. The waters also support recovery and relaxation, making every bath a healing experience.
