The UFC has only recently brought mixed martial arts to the mainstream in the US, but in Japan there’s a long tradition of fights pitting contestants from different disciplines against each other. While they’ve only been called MMA or ‘mixed martial arts’ in recent years, the sport clearly has its roots in these early contests between wrestlers, judo fighters and boxers. In Japan, Antonio Inoki’s fights against world famous martial artists brought great notoriety to the still evolving sport.

Inoki would often face other martial artists in fights that are widely accepted to have been “worked” (having a predetermined outcome) in the same manner as professional wrestling matches. While Inoki faced a number of karate, judo and boxing champions his most famous match was certainly his fight against world heavyweight boxing champion Muhammad Ali.

There’s a great deal of uncertainty about many of the stories surrounding how the event came together and transpired, but a few facts are now known. Ali took the fight as it was a large and presumptively easy paycheck. The big money he was earning is what kept him from walking out when his camp started to disagree with Inoki’s handlers over the rules and ‘finish’ fo the fight. Some suggest that it was supposed to be a fair fight going in, but Ali at the last minute insisted on rules more favorable to him. The more likely version of events is that Ali’s handlers agreed to a predetermined finish, only to have Ali balk at the last moment.

The rules that were in place on fight night were so ridiculously one sided in favor of Ali that it almost defies belief. Inoki wasn’t allowed to hit Ali with a closed fist, nor strike him in the head at all. He was also prohibited from using any sort of choke or submission maneuver. Most problematically, he was prohibited from trying to take Ali to the ground. In other words, Inoki was basically not permitted to do anything that would threaten Ali with any sort of physical harm.

Despite the repeated howls from the media that the fight was ‘fixed’, it was anything but–it was a real fight and painfully boring. Ali did next to nothing, Inoki did whatever he could within the one sided rules. Eventually, Inoki spent most of the fight on the ground trying to throw kicks at Ali’s legs. The event ended up as a 74-74 draw. Both fighters got paid, and the fans got to watch a fight albeit a really, really bad one.

Some interesting trivia about the fight–the referee was former pro wrestler “Judo” Gene Labell, who is considered by many ‘the baddest man on the planet’ even in his 80′s. He could have very likely beaten up both men at the same time–a spectacle that might have been welcomed by the live crowd and closed circuit audience worldwide.

In the aftermath of the fight, Inoki’s popularity was greater than ever–in a perverse way he was something of a hero due to his trying to fight despite the rules being stacked so soundly against him. He remained one of the country’s most popular professional wrestlers and even enjoyed a career in Japan’s parliament. Without missing a beat, he quickly resumed his series of fights against other martial artists who were apparently all more comfortable with the “worked” environment of pro wrestling. Among his “victims” was none other than Leon Spinks, presumably serving as some sort of vindication for his draw with Ali. The popularity of these matches led to a number of promotions that were essentially hybrids of martial arts and pro wrestling, and these led to the big Japanese MMA promotions of today.
