At Wrestle Kingdom 13, White would defeat Okada and would challenge Tanahashi for his newly won IWGP Championship. Unlike their first encounter, White would come out on top and win the top prize in NJPW at only 25.
He would go on to face the NEVER Openweight Champion, Will Ospreay in a champion vs champion match and unlike their last encounter in ROH, this was a different Jay White. Another incredible match from both men but White would come out the victor this time. However, this would be a short lived reign for White as only a few weeks later he would lose the title to Okada after a 54 day reign with no successful title defenses. Personally, I think it was a mistake not giving him a longer more successful reign but based on his talent it probably won’t be the last time he holds NJPW’s top prize.
White would not go beltless for long as a month later he would defeat Naito for the IC Championship becoming a triple crown champion at only 26. However, this would be another short reign after only 104 days he would lose the title to Sanada. This would not stop White in his pursuit to greatness. As he would eventual challenge Kota Ibushi for his title shot at Wrestle Kingdom 15 which was awarded to Ibushi for winning the G1 Climax. It is NJPW equivalent to WWE’s Money In The Bank contract except the date of the match is predetermined for Wrestle Kingdom. White would become the first man to ever take the contract from a G1 winner but he would end up losing to the champion at WK, who happened to be Ibushi.
White teased the possibility of quitting NJPW but instead he would go on to yet again reignite his feud with Tanahashi because he had the one singles belt in NJPW that he had never held in the NEVER Openweight Championship. At Wrestling Dontaku 2021, White would once again take gold off of Tanahashi and become a Grand Slam Champion at only 28 years old holding every singles title that NJPW has to offer for his weight class.
