Watch: Aoki vs. Akiyama fight preview for their legendary clash at ONE X

A grudge match between two Japanese MMA icons will take place at ONE X. Former four-time ONE lightweight champion Shinya 'Tobikan Judan' Aoki will lock horns with K-1 HERO Grand Prix champion Yoshihiro 'Sexyama' Akiyama.

Akiyama is a style icon, model, celebrity and, most importantly, one of the toughest MMA fighters ever. He is one of the few highly touted Japanese fighters to ever compete in the UFC.

Aoki, on his end, is often considered the greatest Japanese MMA fighter of all time. Both warriors have had significant roles in not just making MMA famous in Japan, but also putting Asian MMA on the map.

Adding to the intrigue behind this upcoming matchup, the two icons apparently hate each other's guts as well.

In a ONE X fight preview video released by ONE Championship, we see the trash talk that has led to his highly anticipated grudge match.
