The bout was Hisada's second defense, and the difference in class and experience between the two fighters showed. From the early stages Hisada showed a good defense, good understanding of the ring and managed to neutralise much of Kamikubo's offense whilst trying to see what the challenger had. As the bout went on Hisada began to show more and more of his skills, aggression and power.
In round 3 Hisada began to ramp up the gears, and landed some notable left hooks to the body of the challenger. Kamikubo retreated well, and showed smart footwork, but looked unable to keep Hisada off, who continued to press forward.
In round 4 Hisada's pressure began to tell, shaking the knees of Kamikubo. The moment gave Hisada a great opening and the champion went to work, dropping the challenger with a following up attack. Kamikubo tried to get to his feet, but failed to beat the count.
After the bout the champion made it clear that he was looking to progress to becomign a world champion, though he does look some way from winning a world title at the moment, despite now making his second world title defense.
