Wrestle Kingdom 9 featured two main event matches. In the first, Shinsuke Nakamura defended the IWGP Intercontinental Championship against Kota Ibushi. Ibushi ridiculed Nakamura and used several of the champion's moves, including the corner vibration boot, the reverse powerslam, and the Boma Ye knee strike. Nakamura, responding aggressively, kicked out of the latter at one. Nakamura used a variety of knee-based strikes, and Ibushi's attacks included a standing corkscrew moonsault, a roundhouse kick, an elevated sit-out powerbomb, and a double stomp to the chest. Ibushi also jumped on the top rope, grabbing Nakamura on the apron, and German-suplexed him back into the ring for a two count. In the finishing sequence, Ibushi got up immediately after receiving a knee from the second rope to the back of his head; both attempted the Boma Ye, but Nakamura recovered first with the Landslide and then the Boma Ye knee to retain the title at 20 minutes and 12 seconds. After the match, the wrestlers bumped fists.
