Okinawan martial arts refers to the martial arts, such as karate, tegumi and kobudō, which originated among the indigenous people of Okinawa Island. Due to its location (between "Mainland Japan" and Taiwan), Okinawa was influenced by various cultures with a long history of trade and cultural exchange, including Japan, China and Southeast Asia, that greatly influenced the development of martial arts on Okinawa.
Shuri (首里; Okinawan: スイ Sui or Shui, Northern Ryukyuan: しより Shiyori) 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, hence the name. 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 annexed 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.
