The density of the Kuju-ku-shima Islands (Ninety-nine Islands) is the greatest in Japan. Pleasure cruises, yacht voyage experiences and sea kayak experiences can be tried. Visitors can take a look at the life of locals who make their living in the sea by pearl and oyster farming as well as having a hands-on understanding of the importance of the sea. In the summer of 2009, the Umi Kirara Aquarium was opened. Here visitors can study and experience the Sakai National Park and the living ecosystem of Goto.
