Manhoef. Akiyama defeated Melvin Manhoef at the Hero's light-heavyweight Grand Prix 2006 final round, and gained the champion belt. In K-1 Premium 2006 Dynamite, Akiyama fought the legendary Kazushi Sakuraba in the main event. During the match, Sakuraba called to the referee saying "[Akiyama is] Slippery!" Akiyama went on to win the match with a referee stoppage. This created a controversy amongst MMA fans in Japan, assuming Akiyama was using some sort of body oil or lubricant, banned in K-1 rules.
