Ishigaki island is the number-one choice of diving area in Japan

Ishigaki island is the number-one choice of diving area in Japan.
In the summer, you have a very good chance of seeing a manta ray. From winter through spring, you can see sea slugs and all kinds of young fish! And if you’re keen, you can seek out many other macro-organisms as well.
The clear waters around Ishigaki island and the unique geological formations are also an attractive feature for many divers.
Located between Ishigaki’s neighbor, Taketomi Island, and Iriomote Island is Sekisei Lagoon, which is famous for being the largest lagoon in Japan. On sunny days, the blue color of the water here is absolutely breathtaking. Of the roughly 800 types of coral in the world, half can be found here.
Diving is available all year round at Ishigaki island, so come join us any time!
