The Ao no Tsubo (Blue Cave) is a sea cave located at Maeda Cape in Onna Village, where sunlight shines through and the undersea water glows a mysterious blue color. It is one of the most popular snorkeling and diving spots in Okinawa, and is a spectacular spot visited by many divers and tourists throughout the year.
Cape Maeda, jutting out from the coastline of Onna Village, is one of the most scenic spots in the central Okinawa main island. On the north side of the cape is the famous "Blue Cave," one of the best diving and snorkeling spots in Okinawa, where sunlight shines through the mysterious cobalt blue waters, creating a spectacular view that is unforgettable.
The Blue Cave is a sea cave that opens on a cliff on a cape. The sunlight shining into the cave reflects off the coral sands on the sea bottom, turning the entire cave a fantastic blue color. Visitors can enter the cave by snorkeling or diving, and when they look back outside, they can experience the spectacular view of the entire ocean glowing blue.
The observatory at Cape Maeda offers a panoramic view of the East China Sea, Manzamo and Cape Zanba. It is also known as a famous place for sunsets, and at dusk you can enjoy a spectacular view of the sun setting into the horizon.
The area around the Blue Cave is a "natural aquarium" with a well-developed coral reef and colorful tropical fish such as the bigeye damselfish, roxene damselfish and yellowtail snapper. Even snorkeling beginners can encounter a large number of fish.
