藤原組
In June 1990, after being inspired by Dean Malenko, Shamrock applied for the American tryouts of Japanese Universal Wrestling Federation in Florida. As it was a shoot style promotion, where real strikes and holds were used, Shamrock was put to spar legitimately against other participants, among them Bart Vale. After passing another tryout in Japan, he was eventually accepted, and in October he had his debut match in UWF, wrestling under the name of "Wayne Shamrock" and defeating Yoji Anjo. He became instantly popular and was put on a match against Masakatsu Funaki next. UWF folded shortly after, and Shamrock followed Funaki and other wrestlers to its successor promotion, Pro Wrestling Fujiwara Gumi, led by Yoshiaki Fujiwara.
