Short facts about the championship

Owned by NJPW
Established On the 12th of June, 1987

Structure

A title holder must successfully defend his title to keep it. If he wins the match, he remains champion. If he loses the match, a new champion is crowned.

IWGP Heavyweight ChampionshipIf the current champion can’t and won’t participate in a match to defend his title, a tournament will be held to determine a new champion. This has happened several times in the history of the championship, usually because the reigning champion has been injured.

Belts

The championship has been represented by four different belts. The current belt was introduced in March 2008.

In 2006, Brock Lesnar caused commotion within the wrestling world by refusing to defend his title and refusing to return the physical belt, claiming that NJPW owed him money.

Triple Crown

The (IWGP) Heavyweight Championship consitutes one prong of the (inofficial) New Japan Triple Crown, with the other two components being the IWGP Intercontinental and the NEVER Openweight Championships.

Notable achievments

  • Antonio Inoki became the inagurual champion by defeating Masa Saito in a tournament final.
  • At the time of writing, 7-time winner Hiroshi Tanahashi holds the record for most regins.
  • As of 2016, Okada holds the record for most days as champion with 1,450+ days and counting. Okada has four reigns, with the fourth and current one being the longest of any reign in the title’s history, lasting for 650+ days and still going on.
  • The shortest reign in the history of the title was 16 days long. This is how long Kensuke Sasaki’s fourth reign lasted.
  • When it comes to successful defenses during one individual reign, Okada and Tanahashi are tied on first place with 11 successful defenses. Since Okada’s ongoing fourth reign hasn’t ended at the time of writing, he still has a shot at surpassing Tanahashi.
  • Tanahashi successfully defended his title 28 times over his seven reigns, which is the highest number of successful defenses completed by any of the champions.

Notable foreigners

A vast majority of of the championship winners have been Japanese wrestlers, but a handful of foreigners have also managed to earn their way into this exclusive groups, such as:

  • Leon Allen White (Big Van Vader) from the USA
  • Salman Alkhauzurovich Hashimikov from the Kazakh Soviet Republic (today Kazakhstan)
  • Scott Norton from the USA
  • Robert “Bob” Sapp from the USA
  • Brock Lesnar from the USA
