Okinawa Prefecture is Japan's southernmost region, consisting of more than 160 islands scattered across the East China Sea and the Pacific Ocean. Famous for its tropical beaches, coral reefs, rich Ryukyu culture, and warm climate, Okinawa is one of the country's most popular travel destinations.
Although many travelers simply refer to "Okinawa," the prefecture is actually made up of several island groups, each offering unique landscapes, attractions, and cultural experiences.
