the tour began, he invited Rikidozan, as well as judoka Kokichi Endo and Yasuyuki Sakabe, to participate in these events. After one month of training, Rikidozan made his professional wrestling debut at Ryogoku Memorial Hall on October 28, 1951, wrestling Bruns to a ten-minute time-limit draw. He would continue to work on the rest of the tour, although he would later comment that he had done so with great difficulty, as he lacked the stamina required of wrestlers. Rikidōzan left Japan in February 1952 to work in America for further training and experience. This began with a five-month stint for Mid-Pacific Promotions, where he was trained by Oki Shikina. He established himself as Japan's biggest wrestling star by defeating one American wrestler after another. This was shortly after World War II, and the Japanese needed someone who could stand up to the Americans. Rikidōzan thus became immensely popular in Japan. His American opponents assisted him by portraying themselves as villains who cheated in their matches. Rikidōzan himself was booked as a villain when he wrestled in America early on but went on to become one of the first Japanese wrestlers to be cheered as a baby face in post World War II America. NWA International Heavyweight Champion (1958–1963) Rikidōzan gained worldwide renown when he defeated Lou Thesz for the NWA International Heavyweight Championship on August 27, 1958, in Japan. In another match, Thesz willingly agreed to put over Rikidōzan at the expense of his own reputation. This built up mutual respect between the two wrestlers, and Rikidōzan never forgot what Thesz did. He would go on to capture several NWA titles in matches both in Japan and overseas. Rikidōzan also trained professional wrestling students, including soon-to-be wrestling legends Kanji "Antonio" Inoki, Ooki Kintaro, and Shohei "Giant" Baba. His signature move was the karate chop, which was actually based on sumo's harite, rather than actual karate. Rikidozan had likely conceived the move while being with a Korean-born Karateka, Hideo Nakamura, who was one of Rikidozan's dearest friends. It was rumoured that he had been coached by fellow Korean Masutatsu Oyama. With his success in pro wrestling, Rikidōzan began acquiring properties such as nightclubs, hotels, condominiums and boxing promotions. He established the Japan Pro Wrestling Alliance (JWA), Japan's first professional wrestling promotion, in 1953. His first major feud was against Masahiko Kimura, the famous judoka who had been invited by Rikidōzan to
