One of the big matches of the event saw the Bullet Club stable, which was celebrating its one-year anniversary, take on representatives of NJPW in a four-on-four elimination tag team match. Hiroshi Tanahashi and Togi Makabe survived the match, winning it for NJPW, and afterwards challenged Bullet Club's IWGP Tag Team Champions, Doc Gallows and Karl Anderson, to a title match, but were interrupted by Hirooki Goto and Katsuyori Shibata, who were also eyeing a shot at the title. Another match featured IWGP Intercontinental ChampionShinsuke Nakamura teaming up with Kazushi Sakuraba to take on Daniel and Rolles Gracie. After regaining his title at Invasion Attack 2014, Nakamura was challenged by the Gracies, leading to Sakuraba offering to form a tag team with him. In the build-up to the match, NJPW noted that Daniel holds a mixed martial arts win over Nakamura from December 2002. The Gracies won the match, after which Daniel challenged Nakamura to a title match. The main event featured Kazuchika Okada defending the IWGP Heavyweight Championship against A.J. Styles, who debuted at Invasion Attack 2014 by attacking Okada and revealing himself as the newest member of Bullet Club. At the end of the match, Yujiro Takahashi, who had recently started a storyline, where he began showing disgruntlement towards his current position in NJPW and started walking out on his tag team matches alongside his Chaos stablemates, turned on Okada and the stable and helped Styles win the match and become the 60th IWGP Heavyweight Champion. With the win, Styles became the sixth foreigner to win NJPW's top title.
