Okawa Onsen Isonoyu is a unique, open-air hot spring experience located a short walk from Izu-Okawa Station. To reach the baths, visitors pass through a distinctive tunnel under the Route 135. The facility features separate bathing areas for men and women right on the coast. The spring water is a rare cloudy variety for the Izu area, known for its sodium, calcium, chloride, and sulfate composition. Though a wall obstructs direct sea views from the tubs, standing up offers a view of Oshima Island. Open from 11 AM to 6 PM, admission is ¥500. Note that there are no lockers for valuables.
