On Sunday, the Ultimate Fighting Championship made a long-awaited but triumphant return to Japan with UFC 144, which was also dubbed "UFC Japan." It was the first UFC event in Japan in 12 years, and the first under the current and successful ownership, of Zuffa, LLC, a Las Vegas-based sports promotion company.
