Karate - means Empty Hand. Japanese pronunciation: [kaɾate] Okinawan pronunciation: [kaɽati]), also karate-do (Karate-dō), is a martial art developed in the Ryukyu Kingdom. It developed from the indigenous Ryukyuan martial arts (called te, "hand"; tī in Okinawan) under the influence of Chinese martial arts. While modern karate is primarily a striking art that uses punches and kicks, traditional karate also employs throwing and joint locking techniques. A karate practitioner is called a karate-ka. The Ryukyu Kingdom had been conquered by the Japanese Satsuma Domain and had become its vassal state since 1609, but was formally annexed to the Empire of Japan in 1879 as Okinawa Prefecture. The Ryukyuan samurai (Okinawan: samurē) who had been the bearers of karate lost their privileged position, and with it, karate was in danger of losing transmission. However, karate gradually regained popularity after 1905, when it began to be taught in schools in Okinawa. During the Taishō era (1912-1926), karate was introduced to mainland Japan by Gichin Funakoshi and Motobu Chōki. Karate's popularity was initially sluggish due to its emphasis on kata practice, but when a magazine reported a story about Motobu defeating a foreign boxer in Kyoto, karate rapidly became well known throughout Japan. In this era of escalating Japanese militarism, the name was changed from ("Chinese hand" or "Tang hand") to  ("empty hand") – both of which are pronounced karate in Japanese – to indicate that the Japanese wished to develop the combat form in Japanese style. After World War II, Okinawa became (1945) an important United States military site and karate became popular among servicemen stationed there.[8][9] The martial arts movies of the 1960s and 1970s served to greatly increase the popularity of martial arts around the world, and English-speakers began to use the word karate in a generic way to refer to all striking-based Asian martial arts. Karate schools (dōjōs) began appearing around the world, catering to those with casual interest as well as those seeking a deeper study of the art. Karate, like other Japanese martial arts, is considered to be not only about fighting techniques, but also about spiritual cultivation. Many karate schools and dōjōs have established rules called dōjō kun, which emphasize the perfection of character, the importance of effort, and respect for courtesy. Karate featured at the 2020 Summer Olympics after its inclusion at the Games was supported by the International Olympic Committee. Web Japan (sponsored by the Japanese Ministry of Foreign Affairs) claims that karate has 50 million practitioners worldwide, while the World Karate Federation claims there are 100 million practitioners around the world.
