Mayweather will take on kickboxer Nasukawa in Tokyo

Mayweather will fight on December 31 at Saitama Super Arena in Saitama, Japan.

Despite being 41-years-old, his hands still pack a potent punch, but the addition of elbows, knees, kicks and grappling in MMA represent a huge challenge for a boxer boasting an unblemished 50-0 record dating back to 1996.

Mayweather announced at a Sunday night press conference that he will compete for RIZIN Fighting Federation in a bout against Tenshin Nasukawa, an undefeated kickboxer.

"I want to give the people what they want - blood, sweat and tears", Mayweather told a news conference in Tokyo after reportedly flying into Japan on his private jet.

Floyd Mayweather has announced he is coming out of retirement again.

Floyd Mayweather has been teasing an MMA fight for a long time but his claims were never taken seriously until tonight.

"We'll talk about that, we'll get that situated within the next couple weeks", Mayweather said when asked Monday about the weight and the rules.

Nasukawa, who is 4-0 in MMA and 27-0 in kickboxing, is listed at 5-foot-5, 125 pounds.

Mayweather now appears to have eschewed a lucrative boxing rematch against long-time Filipino rival Manny Pacquiao in favour of a play for a cross-over MMA audience, many of whom had abandoned boxing for the more visceral thrills of the octagon.

Rumour first arose Maywether would take on the young champ yesterday when RIZIN promoter Nobuyuki Sakakibara, while speaking to the media, hinted the idea there would be some sort of partnership extablished. Throughout the years, I've seen a lot of fans from Japan come to Las Vegas and come to the US, but me and my team said let's do something different. He recently defeated former UFC fighter Kyoji Horiguchi in a kickboxing fight. "I will show that to you, so please stay tuned". "I can do anything if I set my mind to it". "My opponent looks taller than he actually is, but I think I could hit him".

"I wanted to do something different".

"I'm pretty sure he's going to bring a lot of excitement".

Ariel Helwani said tonight that the rules and weight still had to be worked out.
