Overview: The area called Koza in Okinawa city-in the center of Okinawa prefecture-is famous for its international atmosphere with immigrants from more than 40 countries. Since the end of World War II, Kadena, the largest American air force base in the Pacific, has largely occupied the city. Services for soldiers in Kadena flourished after the war, ushering in an age of unprecedented prosperity. People from all over the world descended on the city for business opportunities, which led to the melting pot you find today. British actor Dean Newcombe explores exotic Koza.
