New Japan Pro-Wrestling finally has itself a new champion following Kenny Omega's huge win over Kazuchika Okada at Dominion in Osaka, Japan on Saturday.

The latter had carried the IWGP Heavyweight Championship belt for a period lasting well over 700 days, having defended it for a record 12 times, but he would relinquish said title after losing a 2-out-of-3 falls match to Omega at the highly-anticipated event in a duel that lasted over an hour.

Okada and Omega were embroiled in a heated, long-drawn-out rivalry which stretches back to the Wrestle Kingdom 11 main event last year. The Japanese superstar would emerge as the victor then, while Omega got another title shot at Dominion 2017.

The 60-minute time limit draw could not produce a winner, meaning Okada kept his belt. But Omega would finally get one over him at the 2018 G1 Climax and progress to the final, where he fell short in a match against Tetsuya Naito.

The loss saw Omega miss out on a title shot at Wrestle Kingdom 12. However, The Rainmaker issued a challenge after defeating Hiroshi Tanahashi at Wrestling Dontaku last month.

The then-champion stated that it would be an event with no time limit and Omega raised the stakes by adding that it would be a 2-out-of-3 falls match. The Canadian came out on top this weekend, earning another victory against his counterpart to win the IWGP Heavyweight Championship for the first time in his career.

He joins Big Van Vader, AJ Styles, Brock Lesnar, Scott Norton and Bob Sapp as the only foreigners to have won the prestigious accolade.

Okada, meanwhile, had previously talked up his opponent ahead of the showdown, describing Omega as one of the top three wrestlers in the world.

“Kenny, [Tetsuya] Naito, and [Will] Ospreay," he declared. "Aside from myself, those three are what makes NJPW the best promotion in the world.

“Kenny is tough, he’s strong, he’s awesome; I think all those things are pretty obvious, he added. “The thing with him is that with the power of NJPW World, he’s been able to get such a following worldwide. The whole world has their hopes pinned on him and that’s a definite X-factor.”

Okada's reign was quite an impressive one. The WWE, by comparison, hasn't had a champion defend his title as long since Hulk Hogan went on a four-year run before losing his belt to Andre the Giant in 1988.

His fans will obviously be disappointed, but supporters, in general, should appreciate the fact that the NJPW now has a new face; and a pretty good one at that.
