In 2006, Goto joined the American Total Nonstop Action Wrestling (TNA) promotion as a member of Team Japan (consisting of CTU members Goto, Jyushin Thunder Liger, Black Tiger and Minoru), one of the four teams competing in the TNA 2006 World X Cup Tournament. He debuted in TNA on April 23, 2006 at Lockdown, where he teamed with Black Tiger and Minoru against Team USA members Sonjay Dutt, Jay Lethal and Alex Shelley. Team Japan defeated USA when Black Tiger pinned Lethal. On the April 27, 2006, episode of "TNA Impact!", Goto and Minoru lost to Dutt and Shelley, giving a first round victory and two points to Team USA. On May 14, 2006 at Sacrifice, Goto and the other members of Team Japan accompanied Liger to ringside, assisting him in his victory over Team Canada captain Petey Williams. Later that night, all four members of Team Japan took part in a gauntlet match that was won by Team Canada captain Petey Williams. The 2006 World X Cup was won by Team USA (with five points), with Team Japan coming last with three points.
