El Samurai
Takahashi entered New Japan in November 2003 with an extensive amateur background, advancing through the dojo and debuting on July 26, 2004, under his full name. He shortened his name to Yujiro shortly afterwards. From 2007 to 2008 he was a member of the stable Samurai Gym with El Samurai and Ryusuke Taguchi, which ended when Samurai left the company.
