GHCジュニアヘビー級王座
In 2001, Kanemaru underwent a transformation. His simple Bermuda shorts and boots were changed for tights and shinguards, and he began executing more high-risk maneuvers proper for a junior heavyweight. This paid off well for Kanemaru, as he plowed through a field of unlikely but talented competitors to win a tournament for the first-ever GHC Junior Heavyweight Championship. He would go on to win the title twice more, including a win over NJPW's long time junior ace, Jyushin Thunder Liger. In tag teams his experience widened as well, teaming with Tsuyoshi Kikuchi to win the IWGP Junior Heavyweight Tag Team Championship, and with Takashi Sugiura to win the GHC Junior Heavyweight Tag Team Championship twice. His win of the NJPW title served as a catalyst for the creation of the equivalent Noah title.
