Japan’s diving scene used to be a well-kept secret, but more and more people have realised that Japan has much more to offer than just sushi and karaoke. The country spans a vast latitudinal range, from the tropical south where coral reefs dominate around Okinawa and the other Ryukyu Islands, into the almost subarctic north.
