Unsurprisingly Yaegashi did indeed indicate that he would love to have a rematch with Ioka, the current WBA Flyweight champion, and seemed to hint that that was one of the bouts that most interested him going forward.
Sadly Ioka has suggested in the past that the bout would be unlikely, though if public opinion suggests it's worth having there is clearly a chance that Ioka's mind could be swayed towards a rematch.
Their first bout together was a real classic on TBS with Yaegashi entering as the WBA Minimumweight champion and Ioka entering as the WBC Minimumweight champion. The bout was the first true unification bout between Japanese world champions, following a WBC-WBC interim title unification Joichiro Tatsuyoshi and Yasuei Yakushiji back in 1994, and it lived up to the expectations in a big way with both putting on a show.
Since their first bout Ioka has gone on to become a 3-weight world champion, claiming titles at Light Flyweight and Flyweight whilst Yaegashi went on to become the Linear Flyweight champion.
We've got our fingers crossed that a rematch can be made, though suggestions are that Ioka would rather look for unification bouts, at least for now.
