Shōtōkan is a style of karate, developed from various martial arts by Gichin Funakoshi (1868–1957) and his son Gigo Funakoshi (1906–1945). Gichin was born in Okinawa and is widely credited with popularizing "karate do" through a series of public demonstrations, and by promoting the development of university karate clubs. As the most widely practiced style, Shotokan is considered a traditional and influential form of karate do.
