Kozushima Hot Spring Recreation Center has a prominent, vast open-air bath in Japan that uses natural rocky areas! It spans 275m2, without anything blocking overhead. This feeling of openness is perfect for relieving stress. Guests can also admire the starry night sky and experience nature’s planetarium. The small open-air bath also overlooks Sawajiri Bay. This place is ideal for people who want to enjoy the hot spring after a dip in the ocean and be energized for the next day.
