Introduction to the Blue Cave: The Blue Cave is a popular attraction in Okinawa, located on the west coast of Okinawa Main Island, Cape Maeda in Onna Village. The blue cave will automatically emit blue light, which is a typical natural sea cave. Sunlight enters from the narrow entrance of the cave in the world, penetrates the highly transparent sea water and radiates from the white sand on the seabed to illuminate the water surface in the cave, creating a mysterious blue world. In the blue cave, you can not only experience the mysterious blue light but also watch the dazzling colorful tropical fish.
