As well as Kosei's bout there will also be a WBC Youth Bantamweight title defence by Yushi Tanaka who fights against John Bajawa from Indonesia. Although looks a great fight on paper it does need to be noted that Bajawa has lost 3 of his last 4 including an opening round defeat to teenager Ryo Matsumoto.
As for the poster it does show fighters involved in the three most notable bouts, with Shota Hayashi being featured at the bottom, and makes the match ups clear to fans. That's not to say it's perfect but it is a solid enough poster for a decent "lower level" card.
