Prior to winning the Light Middleweight title in 2013 Yuba had a couple of bouts to help him prepare for the 154lb division. One of them saw him battled against the limited but tough and heavy handed Kengo Nagashima. On paper it was a mismatch to help Yuba get used to the weight. In reality it turned out to be a fairly tough bout for Yuba.
In the opening round Yuba dropped Nagashima who was up before 2. From then on it never really looked like Yuba's power troubled the tough Nagashima who had Yuba on the back foot continually. Unfortunately for Nagashima he lacked the skills to really make the taller, faster and more talented Yuba pay for his negativity.
Just a fight later Yuba claimed the Japanese title at 154lbs with an opening blow out against Yosuke Kirima to claim a 5th divisional title. Nagashima however recorded a pair of wins and will be in his first ever title fight on August 10th as he battles Yuki Nonaka, incidentally that bout will be for the now vacant Japanese Light Middleweight title.
