New Japan Showdown featured professional wrestling matches that involved different wrestlers from pre-existing scripted feuds and storylines. Wrestlers portray villains, heroes, or less distinguishable characters in the scripted events that build tension and culminate in a wrestling match or series of matches.
In the IWGP United States Heavyweight Championship match, Lance Archer defended his title against David Finlay. On October 14 at King of Pro-Wrestling, Jon Moxley vacated the IWGP United States Heavyweight Championship, after being unable to wrestle in a scheduled championship defense, due to travel issues arising from Typhoon Hagibis. At the event on October 14, Lance Archer defeated Juice Robinson in a no disqualification match to become the new champion. After the match, Archer attacked Robinson until his partner David Finlay made the save. On November 3 at Power Struggle, Archer challenged Finlay to a match for his title. Finlay had been sidelined with an shoulder injury since February.
El Phantasmo and Sho, who were set to take part in a tag team match for the IWGP Junior Heavyweight Tag Team Championship at Wrestle Kingdom 14 in Tokyo Dome, met in a match, where Phantasmo was set to defend his British Cruiserweight Championship against Sho.
