Pro Wrestling Fujiwara Gumi
In Newborn UWF, Funaki became a top draw for the promotion acting as a nemesis to Akira Maeda. When Newborn UWF folded in December 1990, Funaki decided to sign with mentor Fujiwara's new Pro Wrestling Fujiwara Gumi (PWFG) promotion. Funaki left PWFG in 1993 to form the mixed martial arts promotion Pancrase. Around the same time, Funaki was scouted by K-1 executive Kazuyoshi Ishii to compete in their '93 GP tournament, but he declined, having set his sights on MMA.
