The Ultimate Fighting Championship is bringing its brand of mixed-martial arts back to Japan with not only one of the most highly anticipated heavyweight bouts in recent memory, but also what may be among the most important UFC debuts by a Japanese fighter in some time.

UFC Fight Night Japan 2014 is scheduled for Sept. 20 at Saitama Super Arena. The headline match will be a showdown between heavyweights Mark Hunt and Roy Nelson.

"This is actually a fight most fans have wanted for the last couple of years," Nelson told The Japan Times Thursday afternoon. "I'd say probably the biggest heavyweight fight in UFC history, from just what fans actually want."
