Fighters from Bellator are ready to face off against RIZIN’s best on December 31. Not only that, they will be fighting under unique circumstances: a different rulebook. 

Inside Japan’s Saitama Super Arena, Bellator featherweight champion Patricio Freire faces RIZIN featherweight champion Kleber Koike Erbst, while A. J. McKee faces RIZIN lightweight champion Roberto de Souza. Other matchups feature Kyoji Horiguchi and Soo Chul Kim.

Scott Coker’s fighters are used to fighting under the Unified Rules of MMA. However, this time out, those guidelines will be thrown out the window. Rules will be abided through the The Japan MMA Officials Committee. How much of a difference is there between RIZIN rules and those of the UFC or Bellator?

Here is a guide to how things work at RIZIN.

What are the rules of RIZIN FF?

Unlike American promotions, RIZIN competitors compete in a ring rather than a cage. It is a tradition of Japanese MMA. It can make a major difference regarding ground control.

Regarding the attack plan of a fighter, kicks and knees to the head of a grounded opponent are legal. That includes soccer kicks and stomps, often illegal within the Unified Rules of MMA. Recently, the addition of "12-6" strikes (striking downwards using the point of the elbow) was made legal for RIZIN competitors. 

"I think amongst the many MMA events in the world, RIZIN has in place the most aggressive rules...by unrestricting elbow strikes, I hope that we can move forward with the most thrilling ruleset," RIZIN CEO Nobuyuki Sakakibara stated at a press conference not long ago, via TheFighter.net.

Fights are judged through the following criteria: 

  • Damage: Striking and grappling are judged with the same weight. It will determine how much of the scoring is influenced by the effectiveness of each.
  • Aggressiveness: Determining which fighter was more effective in delivering attacks that can end a fight. While it does not count for the impact of the damage caused, each fighter must be proactive in their approach to the fight. 
  • Generalship: Determining who was more effective in dominating the pace and position (standing up or on the floor) of the fight. 

Fights are also scored as a whole rather than by a round-by-round (10-9, 10-8) basis. Damage, Aggressiveness, and Generalship are scored via the 50, 30, 20 point system, respectively.
