On January 4, 1999, Ogawa was involved with one of the most controversial moments in NJPW history. During his anticipated rubber match with Shinya Hashimoto, Ogawa broke kayfabe and shot on Hashimoto, attacking him for real and leaving him downed and bloodied with kicks and stomps. The NJPW and UFO crews flooded the ring and a legitimate fracas erupted, with Ogawa's cornerman Kazunari Murakami having to be hospitalized by a beatdown by Takashi Iizuka and Naoya himself being slapped by NJPW executive Riki Choshu. During all the brawl, Ogawa taunted the crowd and the wrestlers, having to be accompanied out of the arena by his bodyguard Gerard Gordeau. It was never cleared out how of the incident was real and how it was scripted, but it's believed that Ogawa was ordered by Antonio Inoki to attack Hashimoto in order to hijack the match and increase his popularity.
