Low Ki left Zero-One in mid-2004 to join Pro Wrestling Noah, where he was instantly given a title shot against Global Honored Crown (GHC) Junior Heavyweight Champion Yoshinobu Kanemaru, which he was unable to win. During this period, he represented Noah in MXW Pro Wrestling's Gaijin Battle Series. He later joined New Japan Pro-Wrestling (NJPW) and joined Shinsuke Nakamura's stable RISE, replacing the injured Milano Collection A.T.; in his first match back, he suffered a knee injury, which required surgery. Low Ki returned to the promotion in September, defecting from RISE to join New Japan's main villainous faction, Great Bash Heel (GBH).
