GHCヘビー級王座
During the first few months of Noah's existence, Takayama competed in the first ever GHC Heavyweight Championship tournament, but lost to Mitsuharu Misawa in the final match. He found continued success in Noah, winning the new GHC Tag Team Championship with Takao Omori, too. It was around 2001 that, spurred by his old UWFI comrades' success in the PRIDE fighting circuit, Takayama decided to try his hand at mixed martial arts competition. He also competed in memorable Noah matches during 2002, winning the GHC Heavyweight Championship from Yoshinari Ogawa on September 7 before losing it to Mitsuharu Misawa later that month.
