Wrestle Kingdom 9's other main event was determined at the November 8, 2014, NJPW Power Struggle show. After Shinsuke Nakamura defended the IWGP Intercontinental Championship against Katsuyori Shibata, Kota Ibushi entered the ring, assaulted Nakamura, and issued a title challenge; Nakamura accepted. This was a turning point in Ibushi's career, since he had recently joined the heavyweight division after gaining weight. A previous singles match between Nakamura and Ibushi during the 2013 G1 Climax was ranked "Best Bout of the Year" by the "Tokyo Sports" newspaper.
