Kyushu & Okinawa Castles

九州・沖縄

Kyushu and Okinawa bring together mainland Japanese castle traditions and the wholly distinct stone architecture of the Ryukyu Kingdom. Kumamoto Castle is one of Japan's three great castles and is undergoing ongoing restoration following severe damage in the 2016 earthquake. Fukuoka, Saga, Nagasaki, and Kagoshima preserve significant castle sites reflecting the region's historic role as Japan's gateway to continental Asia. In Okinawa, the Gusuku sites — including Shurijo, Nakagusuku, and Zakimi — are collectively a UNESCO World Heritage Site and represent a tradition of castle-building found nowhere else.
