プリンス・デヴィット
On January 27, 2007, Yujiro participated in a one-night tournament to decide the #1 contender to the IWGP Junior Heavyweight title, also including Wataru Inoue, Ryusuke Taguchi and Prince Devitt; Devitt received a bye to the finals due to Taguchi suffering a right eye injury, and Inoue defeated Yujiro, defeating Devitt in the final as well. On March 18, 2007, Yujiro joined a new mini-faction started by El Samurai called Samurai Gym, along with Ryusuke Taguchi. Yujiro received an opportunity at the junior title by traditional means a few months later, unsuccessfully challenging champion Minoru on May 22, 2007 in his first title shot in New Japan. After nearly three years with the company, Yujiro entered his first Best of the Super Juniors tournament in June 2007, earning 4 points in the group stage by defeating Prince Devitt by forfeit and eventual winner Milano Collection AT by pinfall. Yujiro finished in sixth place out of seven in his block.
