Roy Nelson is easily one of the most adored fighters in mixed martial arts today. Besides for his granite chin, ridiculous punching power, and highlight reel knockouts, fans are infatuated with Nelson’s seemingly non athletic physique.

Nelson has grown into the role over the years, and has even added a ridiculous scraggly beard and ponytail to perfect his look. As we know, UFC president Dana White is not the biggest fan of Nelson’s physique or his words outside the cage, but you could never question Nelson when it comes to his performances inside the Octagon.

In September, the UFC is heading back to Japan and one of the premier fights on the card is a heavyweight battle between Nelson and Mark Hunt. Mixed martial arts fans pleaded with the UFC to make the bout, and UFC officials delivered big time.

In preparation of the event, the UFC recently took a trip to Japan for a pre-fight press conference. Among those in attendance were both Roy Nelson and Mark Hunt.

Prior to the press conference yesterday, Nelson got in some training with the local Japanese sumo wrestlers. Check out the hilarious photo below:

Along with the photo was this caption from the UFC:

How does @roynelsonmma prepare for#UFCFightNight in Japan? By training alongside Japanese sumo wrestlers, of course! #UFCJapan

Maybe when Nelson is finished with his mixed martial arts career he will delve into the world of Sumo wrestling in Japan. It appears that he is right in his comfort zone among those men. One can only hope this will be the case in a few years.
