Floyd Mayweather isn't jumping right back into the ring with Manny Pacquiao ... instead he's taking a tune up fight in Tokyo, with the big money Pacman rematch to follow ... TMZ Sports has learned.
Mayweather called out Manny last weekend, telling Pacquiao and the world he wanted to run back the 2015 super fight in December.
It looks like Floyd is adjusting course a bit ... 'cause sources close to TBE tells us he's actually eyeing 2 comeback fights ... starting with a massive boxing event in Tokyo.
