Wrestle Kingdom 8
Tetsuya Naito used the snub he suffered at Wrestle Kingdom 8 to turn heel and form the "Los Ingobernables de Japon" stable. When he finally won the IWGP Heavyweight Championship from Okada in April 2016 at Invasion Attack, Naito had managed to turn his career around and was now fully embraced by the NJPW fans. There was another rematch between the two at Wrestle Kingdom 12 on January 4, 2018, with the same result as Okada retained against Naito.
