On April 6, 2015, Kanellis managed Bennett and Matt Taven to capture New Japan Pro Wrestling's IWGP Tag Team Championship at Invasion Attack 2015. The following day, NJPW announced that, due to Kanellis' popularity, the promotion had booked its first match involving female wrestlers since October 2002, which would see Kanellis team up with Bennett and Taven to take on Amber Gallows, Doc Gallows and Karl Anderson at Wrestling Dontaku 2015 on May 3.[66] Kanellis pinned Amber to win the match.[67] On July 5 at Dominion 7.5 in Osaka-jo Hall, Kanellis accompanied Bennett and Taven to their first IWGP Tag Team Championship defense against Doc Gallows and Karl Anderson. The Kingdom lost the match and the championship, after Doc Gallows superkicked Kanellis, which distracted Bennett, leaving Taven alone to lose the match
