The bout was Kuroda's first defense since winning the title earlier this year, when he over-came Takuya Kogawa, and it was clear from the opening moments that that there was a gulf in class between the two fighters. Matsuyama, who is really just an entertaining fringe domestic level fighter, had little to really challenge Kuroda.
Kuroda started slowly, and actually had Matsuyama come forward at times, but instead of backing off Kuroda used Matsuyama's courage against him and fought back hard. That resulted in Matsuyama being out fought at his own fight.
After 5 rounds Kuroda was pressing the action more and more, and Matsuyama had no answer whilst falling further and further behind on the cards. After 5 rounds the challenger was in a massive hole, 50-45 on two cards and 50-46 on the third.
From round 6 on wards Kuroda began to let more and more shots go, pressing with more intensity and going for a finish, which eventually came in round 7 when Matsuyama's corner threw in the towel and saves their man from further punishment.
For Matsuyama it was clear this was far too much of a step up. For Kuroda however the win sets him up for a mandatory defense in 2018.
