Akiyama's mixed martial arts debut was in the K-1 Premium 2004 Dynamite event on December 31, 2004, where he defeated boxer Francois Botha by armbar submission in the first round. 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. Though he was an underdog, Akiyama beat Kang by KO in the first round.
