This will be boxing’s 15-time world champion’s fourth such outing since retiring again in the aftermath of his lucrative victory over UFC superstar Conor McGregor in 2017.
Mayweather dominated former sparring partner Don Moore in a rescheduled contest in Abu Dhabi in May, one year after being taken the distance by internet personality Logan Paul in another no-contest.
YouTuber and Rizin featherweight Asakura, a former two-division champion in the Fighting Network Rings promotion, is 16-3-1 as a mixed martial artist, but has his work cut out this weekend.
He will be only too aware of the outcome of Mayweather’s last trip to Japan in December 2018, when kickboxer Tenshin Nasukawa hit the canvas three times before being stopped inside the first round.
And ‘Money’ could well be on similar form here as he looks to tee up a rematch with McGregor in Las Vegas for 2023, while he is also due to face KSI’s brother Deji in November.

Mayweather vs Asakura fight prediction
Mayweather has seemed content to coast through many of these exhibitions, going the distance with Logan Paul and Don Moore to produce no-contests.
The veteran is seemingly happy to continue picking up those vast paycheques without taxing himself too much or risking getting particularly hurt, and at 45 who can blame him.
However, his last visit to Japan saw him decimate Tenshin Nasukawa, who was left in tears after being knocked down three times en route to an emphatic first-round stoppage.
If Floyd decides to turn on the style again, then a similar fate could await his compatriot. Otherwise expect another dominant outing that ends in a disappointing no-contest.
