New Japan Pro-Wrestling
The promotion was founded by Antonio Inoki in 1972 after his departure from the Japan Pro Wrestling Alliance promotion. The first NJPW event took place on March 6, 1972, in Tokyo. Inoki would serve as the president of the promotion until 1989, when he stepped down to pursue a political career as a member of the Japanese House of Councillors. The promotion was a member of the National Wrestling Alliance (NWA) from 1975 to 1985 and once more from 1992 to 1993. NJPW was briefly reaffiliated with the NWA in the late 2000s to the early 2010s as well.
All Japan Pro Wrestling
The promotion was founded by Shohei "Giant" Baba and the Momota brothers, 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, Fred Blassie and The Destroyer.
