Bob Arum is an experienced person and he is promoter who has created many great fights and has brought several fighters to extraordinary success.
But regarding this fight which will take place in Japan, there is really nothing to worry about because right now sales in this event have reached $20 million and this fight is not only about being able to put the championship belt on the line but also to produce money.
Changes such as this one have been occurring for the past few years because other nations are also prospering and right now as we can see, they can promote such high-quality fights in their country and not only there, as of now, we often see some major fights happening in the middle-east as well which wasn't the case before. So as long as they can sell the fights, they don't really care in which country it is as long they secure the safety of the boxers and their earnings. Money can really change almost anything and this scenario is one of the examples we are seeing right now. Pacquiao was a nobody before he came out to the US and everything changed positively for him after that and that was not the case for Inoue right now.
