Power Struggle (2017) was a professional wrestling event promoted by New Japan Pro-Wrestling (NJPW). The event took place on November 5, 2017, in Osaka, Osaka, at the Osaka Prefectural Gymnasium. It was the seventh event under the Power Struggle name. The event featured ten matches (including one match on the pre-show), headlined by Hiroshi Tanahashi defending the IWGP Intercontinental Championship against Kota Ibushi. The show is notable for the promotional returns of Chris Jericho, who made his first appearance for NJPW since 1998, and Jay White, who made his return to NJPW after his excursion to the United States. Storylines Power Struggle featured ten professional wrestling matches that involved different wrestlers from pre-existing scripted feuds and storylines. Wrestlers portrayed villains, heroes, or less distinguishable characters in the scripted events that built tension and culminated in a wrestling match or series of matches.

The match was set up on October 29, when Beretta, having recently joined NJPW's heavyweight ranks, challenged Omega, who accepted.

The match was officially announced two days later. In the IWGP Junior Heavyweight Championship match, Will Ospreay was set to make his first title defense against Marty Scurll.
