Stan Hansen
Inoki became the wrestler most associated with the title due to his high-profile defenses of the title, defeating the likes of Stan Hansen, André the Giant, Tiger Jeet Singh, and Ernie Ladd while champion. Recognized as a four-time NWF Heavyweight champion, between the years of 1973 and 1983, Inoki was champion for all but six months. Inoki's fourth reign was actually due to the decision to hold up the championship, following a defense against Stan Hansen on April 17, 1981 that ended in a no contest. Inoki later regained the title on April 23, 1981 by defeating Hansen in a rematch. He retired the NWF title immediately after the match due to his desire to enter the 1983 IWGP League.
