Ahead of their clash the two men took part in a public weigh in.
On the scales Iwasa was the lighter man coming in at a career lightest 117¼lbs. This is more than 2lbs lighter than he was light time out, when he weighed 119¾lbs against Ricardo Roa and almost 3lbs than he was against Rommy Wassar last September. For a man who has struggled with making the weight in the past it seems the world title opportunity has really helped him focus on getting in to tip-top shape.
Haskins on the other hand made the divisional limit dead on, weighing in at 118lbs on the dot.
This has been the Englishman's weight in 4 of his last 5 fights, with only a stay busy bout against Willy Velazquez breaking that run.
Despite being the lighter man Iwasa was taller and seemed to look the slightly bigger man naturally. That however is no surprise given that Haskins was formerly a Flyweight who has grown into a Bantamweight whilst Iwasa was always a big Bantamweight who will likely move to Super Bantamweight in the future.
For fans wanting to watch this live there's some good news-bad news. British fans will get the fight live on free to air station Channel 5. Sadly however Japanese fans will need to wait for delayed footage which is scheduled for July 4th!
