Champion Carnival
From 1959 to 1972, the Japan Pro Wrestling Alliance (JWA), run by Rikidōzan, held a tournament called World League (also known as the "World Big League"), which featured both Japanese and foreign professional wrestlers. Rikidōzan himself dominated the annual tournament early on, however, after his death in 1963, the tournament was won six times by Giant Baba and once by Antonio Inoki. JWA folded shortly after both Baba and Inoki left the promotion to create All Japan Pro Wrestling (AJPW) and New Japan Pro-Wrestling (NJPW), respectively. Both men took the concept of World League with them to their new promotions, with Baba creating the "Champion Carnival" in 1973 and Inoki creating the World League in 1974, later renaming it G1 Climax.
WAR (wrestling promotion)
Wrestle Association R (formerly known as Wrestle and Romance and abbreviated as WAR) was a Japanese professional wrestling promotion founded and run by Genichiro Tenryu as the successor to Super World of Sports, and which lasted from 1992 to 2000. The promotion initially established as Wrestle and Romance in 1992, had very few regular contracted workers, instead most of the workers were either freelance or employed in other promotions. Because of this WAR ran many all-star cards. It had interpromotional feuds against New Japan Pro Wrestling, Frontier Martial-Arts Wrestling, the new Tokyo Pro Wrestling, and UWF International. WAR also continued, albeit in a loose fashion, SWS's old working agreement with the World Wrestling Federation, when they backed the WWF's first Japanese tour, in 1994.
