Karl Gotch
Inoki met Rikidōzan at the age of 17 and went back to Japan for the Japanese Wrestling Association (JWA) as his disciple. He trained in the JWA dojo under the renowned Karl Gotch, complementing further his training under amateur wrestler Isao Yoshiwara and kosen judoka Kiyotaka Otsubo. One of his dojo classmates was Giant Baba. After Rikidozan's murder, Inoki worked in Baba's shadow until he left for an excursion to the United States in 1964.
