Kensuke Sasaki
In November 2003, Tenzan finally won the IWGP Heavyweight Championship from Yoshihiro Takayama. He would go on to drop the title less than a month later to unlikely victor Shinsuke Nakamura, who, at the young age of 23, became the youngest world champion in company history. Tenzan proceeded to win it three other times (in February 2004 from Genichiro Tenryu, December 2004 from Kensuke Sasaki and May 2005 from Satoshi Kojima).
