Zayne made his debut in NJPW on November 11, 2019, at New Japan Showdown, in a tag team match, where he and Aaron Solow lost against Amazing Red and T. J. Perkins.

In the fall of 2021, Zayne was released from WWE as part of budget cuts relating to the Coronavirus (COVID-19) pandemic, and returned to NJPW Strong, and made his return match at New Japan Showdown defeating Ariya Davari.

Zayne then later faced Will Ospreay on November 17, at the second NJPW's XTRA show in a losing effort.

During the tournament, Zayne formed a tag team with Ace Austin.

On the June 20th episode of IMPACT, Austin defeated Zayne with the help of Chris Bey.
