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.
World Tag Team Championship (AJPW)
The World Tag Team Championship is a professional wrestling tag team championship in Japanese promotion All Japan Pro Wrestling. It was created on June 10, 1988 as a unification of two previous tag team titles in All Japan; the PWF Tag Team Championship, and the NWA International Tag Team Championship; when the PWF champions Jumbo Tsuruta and Yoshiaki Yatsu defeated NWA champions The Road Warriors. As with the Triple Crown Heavyweight Championship, it is symbolized by four belts, two for each wrestler, representing the former PWF and NWA titles. It is currently the top of two tag team titles in AJPW, along with the secondary All Asia Tag Team Championship. There have been a total of 60 recognized individual champions and 53 recognized teams, who have had a combined 82 official reigns.
