Mitsuo and Yoshihiro, sons of Rikidōzan. Baba, a former professional baseball pitcher, joined the Japan Pro Wrestling Alliance (JWA) in 1960. In October 1972, he left the JWA and formed his own group, All Japan. Their first card was on October 21, 1972, at Machida City Gym in Tokyo, Japan. The inaugural roster included Baba, Mitsuo Momota, Akio Sato, Samson Kutsuwada, Motoshi Okuma and Mashio Koma. Thunder Sugiyama, who had recently left International Wrestling Enterprise, also came along to help and brought some lower-level IWE wrestlers with him on a freelance basis. Some personalities from North America also helped with the few cards, including Dory Funk Sr., Terry Funk, Bruno Sammartino, Dominic DeNucci, Freddie Blassie and The Destroyer. Baba established the Pacific Wrestling Federation (PWF) as the governing body for all future titles in All Japan. In the beginning the PWF recognized a world heavyweight championship and several "regional championships" given as billing to foreign stars depending from which region they came from, but after All Japan joined the National Wrestling Alliance (NWA), the PWF world title was downgraded to a regional championship. The first PWF Chairman, who presented the belts to the winners in title bouts, was Lord James Blears. As a loyal member of the NWA, All Japan enjoyed the ability to bring in foreigners, and the NWA World Heavyweight Championship was frequently defended. In the beginning Baba continued the Japanese vs. foreigner formula for the championships, but gradually Dory Funk Jr. and his brother Terry Funk, as well as Mil Máscaras from Mexico became fan favorites when wrestling other foreigners and subsequently one of the few foreign wrestlers to become icons in Japan. Separation from the NWA, new stars and company growth When the NWA territorial system collapsed in the late 1980s and early 1990s, Baba distanced himself from other promoters at home and abroad, and began a system of promoting talent (both Japanese and foreign) who competed exclusively for his promotion. With the unification of the titles in All Japan into the Triple Crown Heavyweight and the World Tag Team Championship, as well as the promotion of talent including Jumbo Tsuruta, Genichiro Tenryu, Akira Taue, Mitsuharu Misawa, Toshiaki Kawada and Kenta Kobashi, the promotion was able to carve a loyal fanbase that lasted during the 1990s. Interpromotional matches were rare, and wrestlers who arrived from other Japanese promotions (such as Hiroshi Hase, Shigeo Okumura and Yoshihiro
