Former five division world champion Floyd Mayweather is gearing up for another trip to Japan in the summer.

According to Mayweather, he plans to take part in another exhibition bout.

The 42-year-old former boxer traveled to Japan on New Year's Eve, and knocked out undefeated kickboxer Tenshin Nasukawa in a single round. Nasukawa was grossly undersized and was dropped three times before the contest was waved off.

The fight with Nasukawa was scheduled to be a three round bout, with no scores or winner being announced - and fought under traditional boxing rules.

This time around, Mayweather says he will face a ex-boxer - but he's unsure of the name or weight class.

MMA company RIZIN had promoted the initial exhibition and is likely handling the next one.

Last Saturday night, Mayweather told reporters that he brokered a deal where his undefeated pupil, WBA super featherweight champion Gervonta Davis, would travel over to Japan in April for an exhibition with Nasukawa.

Mayweather expects to take part in several exhibitions before the year is over.

"They called me, I got another one in Japan, in July... for like $10 million, three rounds. I got another one in July, same rules, always my rules. It's a Japanese boxer, a former boxer from what I heard, I got a call today. In exhibitions this year alone, I think I got about 4 or 5 exhibitions this year... I'll make about $80 million, this year," Mayweather told TMZ.

Mayweather retired from boxing in September of 2015, after dominating Andre Berto over twelve rounds. He briefly came back in August 2017, to secure a TKO win in a cross-sport bout against UFC superstar Conor McGregor. Afterwards, he retired once again.

There are still lingering rumors of a potential rematch with Manny Pacquiao - but Mayweather refuses to discuss the idea of that bout.
