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.
Sky Diving J
Sky Diving J was a professional wrestling event produced by New Japan Pro-Wrestling (NJPW). The event took place on June 17, 1996 at the Nippon Budokan in Tokyo, Japan. The event was notable for revolutionizing junior heavyweight wrestling in NJPW and Japanese wrestling history. The event aired on television on TV Asahi on July 6, 1996. All of the matches contested at the event were junior heavyweight championship matches from different promotions from Japan. This was a very significant event in the revolution of junior heavyweight wrestling as title defences from various promotions at the event would result in the unification of various junior heavyweight championships to create the J-Crown.
