Mayweather to fight kickboxer in Japan on New Year’s Eve

US boxer Floyd Mayweather Jr. has announced he had signed with Japanese mixed martial arts promotions company RIZIN Fighting Federation to fight kickboxer Tenshin Nasukawa on New Year’s Eve in Saitama.

The undefeated 41-year-old, who has won world boxing titles in five different weight categories, has never fought professionally in mixed martial arts and it has yet to be decided what format and rules the fight would follow.

His opponent will be 20-year-old Japanese kickboxer Tenshin Nasukawa at the RIZIN.14 event.

Speaking at a news conference in Tokyo on Monday, Mayweather said the decision to fight in Japan was about expanding his global profile.

I wanted to do something different. I wanted to display my skills outside the U.S. and be in a special fight, he said.

I spoke with my team and with RIZIN and we put it together.

I have fought in the U.S. for all 50 of my fights… As a professional I haven’t had a chance to go outside the U.S. to display my skills and to display my talent for the world.

Nasukawa competes in their championships in both MMA and pure kickboxing. He has won all four of his MMA fights.

While boxing rules restrict bouts to the use of fists, MMA rules can incorporate kicks, knees and elbow strikes, as well as wrestling, joint locks and chokes.

Mayweather said the terms of the fight would be decided in the coming weeks.

As far as the weight class and the rules, we will talk about that and will get that situated within the next couple of weeks, said Mayweather.
