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.
NWA Intercontinental Tag Team Championship
The NWA Intercontinental Tag Team Championship is a professional wrestling tag team title in Japanese promotion Pro Wrestling Zero1, typically reserved for (but not exclusive to) heavyweight (>) wrestlers. It was created on June 14, 2001, three months after then Pro Wrestling Zero-One's creation, when Samoa Joe & Keiji Sakoda (though Zero1 has since ceased to recognize both their reign as well as the following reign by Steve Corino and Mike Rapada) defeated Yuuki Ishikawa & Katsumi Usuda. This was during a time when Zero-One was a member of the National Wrestling Alliance; since the two organizations' parting in late 2004, the NWA does not recognize or sanction it, though it retains the NWA initials. It is one of two tag team titles currently active in Zero1, along with the NWA International Lightweight Tag Team Championship, contested exclusively among junior heavyweights. There have been a total of 43 recognized individual champions and 37 recognized teams, who have had a combined 42 official reigns.
