After a tense alliance between them formed for the Rikidozan Memorial, Hashimoto challenged Ogawa to a last match, in which Hashimoto would retire from professional wrestling if he lost. Ogawa and Hashimoto fought the last time of their careers on April 7 at the Tokyo Dome, where Naoya defeated Hashimoto by KO after several iterations of his Space Tornado Ogawa technique. His opponent carried out and performed a retirement ceremony, while Inoki and other tried to convince him not to do it; even Ogawa declared in a segment that he repented having finished off the career of his rival.
