Yoshinobu Kanemaru
March 1, 2003 saw Kenta team with Naomichi Marufuji for the first time against Makoto Hashi and Yoshinobu Kanemaru in a winning effort. They began teaming regularly as the two entered into a tournament to christen the first GHC Junior Heavyweight Tag Team Champions during the company's "Accomplish Our Third Navigation tour"; they went to win the tournament by defeating junior heavyweight veterans Jyushin Thunder Liger and Takehiro Murahama in the finals on July 16. While defending the tag team title, Kenta continued his venture in hopes of winning the GHC Junior Heavyweight title once again on November 30, 2003, in an unsuccessful bid against Takashi Sugiura.
