Current ROH World champion Claudio Castagnoli will be making his New Japan Pro-Wrestling debut on the Dominion show on June 4.
Castagnoli, who never wrestled for the Japanese promotion before, will be teaming up with his BCC team mate Jon Moxley and Shota Umino as they take on Kazuchika Okada, Hiroshi Tanahashi, and Tomohiro Ishii for the NEVER Openweight Six-Man Tag Team titles.
Castagnoli had expressed his wish in the past to wrestle at a New Japan show but that was not possible while he was part of WWE. He made his AEW debut at the AEWxNJPW: Forbidden Door last June in Chicago.
Dominion 6.4 will take place at the Osaka-jo Hall in Osaka.
