#5.) Yuji Nagata – 392 days
When Kazuchika Okada was defeated by AJ Styles in early 2014 for the IWGP Heavyweight title, it meant that his reign fell short of the then-4th longest title reign of all time. His reign ended at 391 days, one shy of Nagata’s first reign. For those who don’t know, Yuji Nagata was a very important figure for NJPW in the 2000s, being one of their major pillars.
In 2002, he defeated Tadao Yasuda, going on to hold the title for over a full calendar year before dropping it to Yoshihiro Takayama at Ultimate Crush 2003. With 10 title defenses, he was a true fighting champion.
