Japan is perhaps not the first choice for most divers but, with over 2 000 dive spots ranging from the tropical waters of Okinawa to ice diving in northern Hokkaido, it should definitely be in the list. Izu Peninsula is the most popular dive destination on the mainland. Some of the more popular spots are Futo, known for its eagle rays, Kumomi and the tiny island of Mikomoto with deep, clear water, big fish and strong currents. However, all the really great diving areas are from the smaller archipelagos Okinawa archipelago is a tropical paradise with extremely clear waters and over 400 types of corals. There are colorful reefs full of unique nudibranchs, sea fans, sea turtles, whale sharks, manta rays and a schooling of hammerhead sharks. Caves, air domes and underwater ruins can also be explored here. The Kerama Islands are the closest to the mainland and offer some of the best dive spots in the region, with crystal clear water and amazing coral formations. The USS Emmons WWII wreck and beautiful reefs can be dived here. The Yaeyama Islands are the westernmost part of Okinawa. There are pristine coral reefs that surround practically all the islands. Ishigaki Island is known for its manta rays, while Yonaguni Island’s star attractions are hammerhead sharks and the mysterious underwater ruins dated by some to be 8000 years old. Much of the southern coastline is dotted with caverns, caves and underwater rock formations. For the adventurous diver, it is possible to go ice-diving in the Sea of Okhotsk, off the coast of Hokkaido where there are many beautiful ice drifts. Other popular spots in Northern Japan include the island of Sado and the coast of the Tsugaru Peninsula. Most sites in Northern Japan are spectacular dives, completely different from Southern Japan. The waters of Japan are generally diveable all year, but the best time is from mid-July to early September. Also, beware of the typhoons during June to November.
