The Shuri Castle Shureimon (Shurei Gate) is the main symbolic gateway to the historic Shuri Castle complex in Okinawa, Japan, a former royal palace of the Ryukyu Kingdom.Built in the early 16th century, this vibrant, red-tiled gate is known for its unique Okinawan architectural style influenced by China and features the Hanzi characters "Shurei no Kuni" ("Land of Propriety"). The Shureimon was destroyed during the Battle of Okinawa in 1945 and was most recently rebuilt in 1958, serving as a prominent symbol of Okinawan culture and a historic landmark even as the castle undergoes ongoing reconstruction after a 2019 fire
