Pro Wrestling Fujiwara Group ("Purofesshonaru-resuringu Fujiwara-Gumi", プロフェッショナルレスリング藤原組) was a shoot style professional wrestling promotion based in Japan, operating from 1991 to 1996. It was formed by Yoshiaki Fujiwara, Masakatsu Funaki and Minoru Suzuki after the collapse of the Japanese UWF. Using only the above description and what you know about the world, "Pro Wrestling Fujiwara Group operated for 7 years." is definitely correct, incorrect, or inconclusive?
