When the junior heavyweight boom started in Japan under Tatsumi Fujinami and the original Tiger Mask, Satoru Sayama, Onita was picked as the ace of AJPW's makeshift junior heavyweight division. Baba was able to get Chavo Guerrero, Sr., who had been an early rival of Fujinami, over to AJPW's side, and Guerrero brought the NWA International Junior Heavyweight Championship with him, effectively establishing it as AJPW's junior heavyweight cornerstone. Onita and Guerrero's subsequent feud over the title spanned three promotions (AJPW, Jim Crockett Promotions and Empresa Mexicana de Lucha Libre), and, while not as spectacular as New Japan Pro-Wrestling's junior division, provided solid alternate wrestling to AJPW fans. On January 3, 1985, he had to retire due to accumulated injuries, after a failed comeback attempt, which ended after his last match on December 2, 1984, against Mighty Inoue. He would be replaced by Masanobu Fuchi as the new junior heavyweight ace of AJPW.
