Omijima Island is located in the midst of the clear ocean waters of Kita-Nagato Kaigan Quasi-National Park. With the open ocean waters off the rocky coast of Funabashi (on the west side), and the white beaches of Shizu-ura, from which a beautiful world of seaweed extends, diving and snorkeling can be enjoyed year-round on Omijima Island. Additionally, because of the island's unusual shape, divers have only to go underwater a little ways to enjoy some incredible sea life. Beginners and children as young as fourth grade (elementary school) may also participate (with some conditions).
