Origins and Lineage of the IWGP Heavyweight Championship

The championship was officially introduced in June 1987, replacing the earlier IWGP League tournaments. The concept was spearheaded by Antonio Inoki, NJPW’s founder, who wanted a title based on true competition rather than pure spectacle.

The first champion, Antonio Inoki, set the tone for what the belt would represent: skill, endurance, and legacy. Unlike other promotions, NJPW ensured the IWGP title was defended sparingly, making every defense a major event.
