Hida-Osaka Onsen
An exceptionally rare high-concentration natural carbonated spring in Japan. It emerges clear and colorless, but because it contains a lot of iron, it turns a vivid brownish color when exposed to air. It has a lively sparkling texture and is prized for its excellent ability to retain warmth and keep the body warm from deep within. At the drinking spring area, you can directly taste the stimulating carbonation, supporting your health from the inside as well.
