Momota debuted on May 27, 1970 for the JWA, the promotion that was founded by his father Rikidozan, the father of Puroresu. His first match was a six man battle royal which he lost to Ushinosuke Hayashi. After competing here and there over the next few months, he scored his first win on December 4 when he won a ten man battle royal last defeating Hayashi. Momota would continue to work for the JWA throughout 1971 mostly low on the card and paying his dues during which time he faced the likes of Akio Sato and future legends Osamu Kido and Tatsumi Fujinami. His last match would be on December 12 scoring a win over Masashi Ozawa (the future Killer Khan).
