playoff for the championship. He fought in 23 tournaments in total, with a win–loss record of 135–82. His highest rank was sekiwake, though he was reportedly close to a promotion to ōzeki before his retirement. Several reasons have been given for Rikidōzan's retirement. The amount of success he had earned despite his humble beginnings was a source of envy amongst his seniors in Nishonoseki. Racial discrimination may have also been a factor, but the impetus for his retirement came due to a financial dispute with stable-master Tamanoumi Daitarō. Rikidozan felt that his substantial contributions to the stable made him worthy of major financial support, but Tamanoumi considered him selfish, and he was refused after a heated argument. While the public explanation for his retirement claimed that he suffered from paragonimiasis, the truth was that on September 10, 1950, soon after the argument with Tamanoumi, Rikidozan "impulsively" cut his own chonmage. After his retirement, Rikidozan initially worked alongside Americans as a black marketeer. His business came through purchasing the belongings of US soldiers departing for service in Korea, and selling these goods to the Japanese. He eventually left this job, and after a petition to return to sumo was rejected, he was given work as a construction supervisor by his former patron Shinsaku Nitta. Nitta had worked in a Tokyo prisoner-of-war camp during World War II, and had secretly provided American prisoners with food and cigarettes; to repay him for his kindness, former prisoners who went on to work at the GHQ gave his construction company preferential treatment when contracting reconstruction work. Nitta also had ties to the criminal underworld, and had been deeply involved with sumo in this manner.

These events would be promoted by Honolulu businessman Moe Lipton. Around this time, Rikidōzan reportedly expressed interest in becoming a professional wrestler. In September, wrestling promoter Al Karasick of Honolulu-based Mid-Pacific Promotions announced that he, alongside Joe Malcewicz of NWA San Francisco, had secured a deal with Lipton. Karasick and Malcewisz would send six wrestlers for a twelve-date tour, held from September 30 to December 11. These wrestlers included Harold Sakata and Mid-Pacific booker Bobby Bruns.
