Okinawa, a prefecture rich in history and culture, is home to some of Japan’s most unique historical structures—its castles. Unlike the mainland’s castles, often built in the Japanese architectural style with wooden beams and tiled roofs, Okinawan castles, or “Gusuku,” feature stone walls and offer strategic views over the surrounding landscapes and seas. These castles are not just tourist attractions but sacred sites that tell the tale of the Ryukyu Kingdom’s grandeur. This article guides you through some of Okinawa’s most significant castles, each a gateway to the past and a testament to the island’s rich historical tapestry.
