Boxer Floyd Mayweather will fight kickboxer Tenshin Nasukawa in Japan on 31 December, after signing a deal with a mixed martial arts company.

"It wasn't easy to make this happen, but we told the people anything is possible and now we're here and we want to make sure we give the people in Tokyo what they want to see - blood, sweat and tears", Mayweather said during a press conference.

The 41-year-old boxer, unbeaten in all 50 of his career fights, has always been mooted with a move to mixed martial arts to fight Conor McGregor or Khabib Nurmagomedov.

"I have fought in the USA for all 50 of my fights".

Sakakibara, who established Rizin FF in 2015, rose to prominence as the president and co-founder of Pride Fighting Championships, the wildly popular and influential Japanese mixed martial arts company that was sold to the parent company of the Ultimate Fighting Championship (UFC) in 2007. It's all about me going out there and displaying my skills against another skillful fighter.

While the rules of the bout have yet to be determined, Mayweather teased the public with what could be coming.

"I'm older now", Mayweather said.

In the meantime, Mayweather will take on Nasukawa, who is 27-0 with 21 knockouts in kickboxing and 4-0 with two knockouts in MMA.

Floyd Mayweather is set to fight a 20-year-old Japanese kickboxer in a stunning development in the combat sports world.

Mayweather, who stopped McGregor in the 10th round previous year after coming out of retirement for a $275 million pay day, had been flirting with the idea of a rematch with the Irishman or facing fearsome Russian Khabib Nurmagomedov.

"I want to continue to build my relationship with Money Team Tokyo", Mayweather said. It is believed that rules are still being negotiated and finalized between the parties and RIZIN.

Regardless of the final rules of the bout, the move makes a potential rematch with McGregor or a fight against Nurmagomedov much more likely than it felt just days ago.

"We do foolish things sometimes but I am not a damn fool".

Which makes this fight even more surprising.

"But this is the last one, you have my word on it". He is expected to return to the United States on Tuesday to begin training.
