Blue Cave is extremely popular in Okinawa and is a beautiful underwater cave! The only "blue hole" in the world is located at Cape Mayada in Onna Village in the northern part of Okinawa. It is a cave in the bay created by long-term sea erosion. Through the refraction of sunlight, the white sand on the seabed reflects and emits a mysterious blue light. The clear and transparent sea water changes with the terrain, and is dyed with gradients like a canvas.
