Nasukawa, 20, is unbeaten in 27 kickboxing fights and has a record of 4-0 in MMA.
Mayweather and Nasukawa appeared at a news conference in Tokyo on Monday (Sunday night United States time) that was streamed worldwide on YouTube to announce the fight with officials from the Rizin Fighting Federation, a Japanese promotional company founded in 2015 that puts on MMA and kickboxing events. This particular bout is a special bout as far as we're giving the people something they've never seen before.
When Mayweather last fought below the 147lbs limit was three years ago - so it's likely to be a challenge taking on the kickboxer as he has won various titles in the flyweight (125lb) and bantamweight (135lb) divisions - ultimately this raises an obvious question about the contracted weight for the fight. "When it's all said and done, it's all about me going out there and displaying my skills against another skillful fighter". Though many took Mayweather's MMA aspirations as a bluff, it looks like he may actually back up his talk ... just not against any UFC competition.
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.
"I think my role as a fighter is to make sure that fighting here in Japan gathers a lot of excitement", the Tokyo native said through a translator. It's not out of the realm of possibility that the bout is fought under kickboxing rules.
Mayweather had said in September that he was coming out of retirement for another fight with Manny Pacquiao after the two of them had been pictured talking at a music festival in Japan. My punch can change history. "I can do anything if I set my mind to it".
"I want to continue to build my relationship with Money Team Tokyo", he added, promoting the cross-code bout as an expansion of his businesses into Japan.
"We've been making some huge fights happen in the USA, but we look forward to taking the Mayweather Promotions banner and the TMT banner worldwide".
"I have fought in the US for all 50 of my fights".
