船越義珍
is a style of karate, developed from various martial arts by Gichin Funakoshi (1868–1957) and his son Gigo (Yoshitaka) Funakoshi (1906–1945). Gichin Funakoshi 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, including those at Keio, Waseda, Hitotsubashi (Shodai), Takushoku, Chuo, Gakushuin, and Hosei.
