Donaire was a great example of a true champion, as he was well aware that Inoue could beat him again, and yet he still risked a unification match to test himself against Inoue once more.
Inoue is also a great example as he always seeks to fight the best opponents, which is why he became an undisputed champion in the bantamweight division. After winning, he wasted no time in moving up for the super bantamweight title match. If he succeeds again, it would be a tremendous accomplishment, and I am certain he will continue pushing his limits.
He had to climb in ranks though, as he started is fights all in Japan, but his handlers knows his true potential and they have been given the chance to fight in the US and be exposed from boxing fans because of Bob Arum.
So we might hate Bob Arum and Top Rank, but surely they know how to promote a fighter like Manny Pacquiao. And after winning the WBSS tournament, Inoue become a household name in the US and then he started his path to defeat all great fighters unifying all the belts.
Now, his journey continues as he might want to do it at 122 lbs.
There will be a time in the future for sure that he will have to fight in other countries like in US or somewhere in Europe, or even in the Middle East if Inoue will face an opponent that have a much bigger name than him. But not now because the organizer and promoter is more inclined to make the fight happen in Japan as it was already evident that they can generate big profits in that certain country and considering that Inoue won this fight and will take the undisputed fight, I'm also confident that they will contest the fight in Japan again instead of the Philippines where Marlon Tapales came from.
