Aside from competing in Pro Wrestling Noah, Kenta has been able to compete abroad in the United States with other participating members of the GPWA. His first appearance in the country was with Ring of Honor at Final Battle 2005, as a fan favorite, defending the GHC Junior Heavyweight title against Low Ki. He returned to the company the following year for Best in the World in New York City on March 25 where he and Naomichi Marufuji defeated the team of Samoa Joe and ROH World champion Bryan Danielson after Kenta connected with his finishing strike, the Go 2 Sleep, on Danielson. Kenta returned for "In Your Face" featuring him in a three-way match against Joe and Danielson, which ended in similar fashion.
