In 2005, Yoshihashi tried to earn a training spot in the New Japan Pro-Wrestling (NJPW) dojo, but failed to pass an introductory test. He was eventually accepted into the dojo, after passing the test on his third attempt,[4] and made his professional wrestling debut on July 6, 2008, losing to Tetsuya Naito. Although not competing in the 2008 G1 Climax, he did wrestle on many of the G1 Climax shows.
