Ishigaki's climate is semi-tropical and the ocean which surrounds the Yaeyama archipelago remains warm year-round. Popular for manta rays, the most reliable place to view these magnificent creatures is 'Manta Point' (also known as 'Manta Scramble') which is located just off Kabira's coast. Mantas make their way to this point to clean and feed on plankton, however, there are other sites where they are frequently spotted throughout the archipelago.
Coral is also in abundance. Indeed, in many cases expansive areas of coral are located so close to the shoreline. Shiraho is a town positioned on the south west coast of Ishigaki and the waters off its coast are famed for having one of the largest areas of blue coral in the world.
There are also a number of drop-offs and cave diving opportunities to be enjoyed on the island and it is often said that Ishigaki compares well will better known dive locations throughout Asia.
