Shuri (首里, Okinawan: スイ Sui or Shui, Northern Ryukyuan: しより Shiyori[1]) is a district of the city of Naha, Okinawa, Japan. Formerly a separate city in and of itself, it was once the royal capital of the Ryūkyū Kingdom. A number of famous historical sites are located in Shuri, including Shuri Castle, the Shureimon gate, Sunuhyan-utaki (a sacred space of the native Ryukyuan religion), and royal mausoleum Tamaudun, all of which are designated World Heritage Sites by UNESCO.
Originally established as a castle town surrounding the royal palace, Shuri ceased to be the capital when the kingdom was abolished and incorporated into Japan as Okinawa prefecture. In 1896, Shuri was made a ward (区, ku) of the new prefectural capital, Naha, though it was made a separate city again in 1921. In 1954, it was merged again into Naha.[2]
