Access to these islands is made relatively easy by a good network of ferries and flights.
The subtropical islands of Okinawa combine white sands and turquoise-blue waters with a fascinating culture—quite different from that of the Japanese mainland. Located 1,500 kilometers south of Tokyo, access is generally by plane to the main island's capital of Naha . There are regular flights to Naha from the major mainland airports on Japan's main carriers, All Nippon Airways and Japan Airlines, as well as some budget airlines. Flights to Ishigaki Island and Miyakojima Island are now an option.
The Izu archipelago islands are easily accessed from Tokyo's Takeshiba Pier. Officially part of the Tokyo domain, the rural getaways are ideal if you want to experience the quieter side of the metropolis for a couple of days. The most common way to get to the islands is to travel by ship . Both slow passenger ships, and high-speed ferries are available depending on your flexibility, and propeller planes also fly there.
The Ogasawara islands are a cluster of 30 islands located around 1,000 kilometers from Tokyo. The World Heritage designated archipelago is ideal if you are a nature lover looking to explore the diverse and fascinating ecosystems of the islands. Access to the Ogasawara Islands is only by boat and is made as part of a fixed six-day schedule.
Japan's many other islands are just as easily accessed. From the natural beauty and festivals of Sado Island in Niigata Prefecture , the abandoned military forts of Tomogashima Island in Wakayama Prefecture , the smoky volcanic island of Sakurajima in Kagoshima Prefecture and many more. Make sure to fit in some island adventures during your Japanese trip.
