I'm just curious, is there any governing body that regulates these exhibition fights? In professional boxing, there are regulatory bodies ensuring all requirements are complied with before a fight happens, but in exhibition fights, they seem more concerned with the promotion of the fight, rather than the preparation of the boxers.
The country's sports commission where the fight will be held in this case Japan, no fight professional or exhibition can be held without a license or a permit it's illegal to do that.
And on your second question, both fighters are professional fighters who know how to condition themselves and both fighters are fully prepared before they get in the ring.
Pacquiao will win this fight the Japanese who is an MMA is just too amateur in boxing that he will have no chance against a legendary boxer like Pacquiao.
Yes, in this case it will be the Japanese Boxing Commission who's going to give this fight a green light. And obviously, this is just exhibition and so there are safety nets for this kind of fights, like the weight of the gloves, minutes per round and how many rounds they will be.
But in any case, since this is a boxing match, Manny will have the advantage although I think the Japanese fighters have some pride in them even in exhibition, Suzuki will be the aggressor as he is the younger fighter, but it will be futile as he might awake the monster in Manny here.
