The Kerama Islands are located 30-40 kilometers north of Naha, the prefectural capital located on the island of Okinawa. The Kerama Islands include some 20 small and large islands, all of which are surrounded by coral reefs and unbelievably transparent seas. Only five of the islands are inhabited -- Tokashiki, Maejima, Zamami, Aka and Geruma -- while the others are deserted. Humpback whales migrate through the Keramas' waters every winter and can be seen on one of the local tours. There is a wide variety of minshuku and pensions on Tokashiki, Zamami and Aka. This is an ideal place for snorkeling as it is widely inhabited by sea turtles. Five to six ferries depart every day from Aka to Zamami.

One of the most fascinating dive sites in Okinawa, the Kerama Islands prompt many a diver from around the world to keep coming back to see its extraordinarily beautiful waters and incredible underwater sights. There are numerous places of accommodation and dive shops where English is spoken. A day tour is available for those whose time is limited. The Kerama Islands are a great place to refresh the mind and body by getting away from the hustle and bustle of daily life.

The Kerama Islands will be designated Japan’s 31st national park on March 5, 2014, known as Coral Day in Okinawa. The islands’ beautiful coral reefs and clear waters serve as the habitat for approximately 250 species of coral and a breeding ground for humpback whales.
