In March, Tetsuya Naito won the 2016 New Japan Cup, defeating Hirooki Goto in the finals in a rematch from Wrestle Kingdom 10. On April 10 at Invasion Attack, Naito defeated Kazuchika Okada with help from "Los Ingobernables de Japon", including the debuting Seiya Sanada, to win the IWGP Heavyweight Championship for the first time in front of a Ryōgoku Kokugikan crowd that was firmly behind him.
