The champion won the title last June, when he defeated Takuya Kogawa and unified the Japanese interim and regular titles. Since then he has defended the belt once, taking a 7th round TKO win over the limited but exciting Mako Matsuyama, in a mismatch. Those wins have seen Kuroda extend his current unbeaten run to 4 fights, following a bit rough patch in his career, where he went 3-4-3 in a 10 bout run. It was during that run that many felt Kuroda had seen his best days, but his current run of form looks like it's a bit of an Indian summer for his career, and he is moving up the world rankings, with top 15 rankings with all 4 world title bodies.
Kuroda had first made a name for himself fighting at Light Flyweight, where he won the Japanese title back in 2011 with a win over Yuki Sano. He would defend that title 3 times, including a defense against Ryoichi Taguchi, before losing in a world title fight to Juan Carlos Reveco at Flyweight. The move up in weight caused problems for Kuroda who never really seemed to settle at Flyweight until 2016, in which time he has gone 5-1 with his only loss being avenge last year.
In the ring Kuroda is a well schooled boxer with nice combinations, a good work rate, sharp speed and good skills. He's not the biggest puncher, but he's a solid fighter, who has has only been stopped once, by Suguru Muranaka, and is a handful for fighters on the Japanese scene. There is a clear gap between him and the elite Japanese fighters at Flyweight, world champions Daigo Higa and Sho Kimura, but there's no other Japanese fighter who would have an easy time with him. That include his upcoming foe Nagamine, the touted Junto Naaktani or OPF champion Keisuke Nakayama.
Aged 26 Nagamine is much younger than the champion and a more pure puncher, though is a man who has a couple of nagging issues over his head.
He debuted in 2011 and the following year he was crowned the Rookie of the Year at Flyweight and looked set for a big future. Sadly however he suffered an eye injury in 2013 that kept him out of the ring for almost 17 months. His return to the ring was a successful one in late 2014, but the following year was re-injured as he was stopped by Ken Shiro, in what was an excellent performance by the future WBC Light Flyweight cahampion. Nagamine would then spend almost a year re-healing his injury before returning to stop Kenya Yamashita in a 3 round thriller. Since then he has gone 3-0-1 (3) earning this title fight in the process.
Although a little rough around the edges, and a little bit slower than some of his opponents, Nagamine has proven to be a tough and heavy handed fighter, with good skills and a real will to win. His bout with Yamashita was a special shoot out, where he had to climb off the canvas to stop his foe, whilst a win over Mako Matsuyama showed he enjoys a war just as much fans watching. Sadly however he was totally out boxed by Ken Shiro, who used speed, movement and a jab to dominate. Those same tools are in Kuroda's arsenal and Nagamine will have to find a way to deal with them.
Although not the best boxer Nagamine has nasty power. His last 4 wins have stoppages, and he has shown he carries legitimate power in both hands, and whilst the shots might not always be the sharpest when he lands he is dangerous. Even his jab looks a very damaging shot. He will have a height advantage over Kuroda and will look to use that to his advantage, boxing at range and using his power. If he gets up close and manages to force a war he has a chance, but he needs to make it into a fight, and take away the edge in skills and speed that Kuroda has.
We favour the skills of Kuroda here, but not by much. Kuroda's extra experience at title level, slightly more rounded skills and slightly more refined know how are what swings us in his direction, it's not by much, and we know Nagamine has the power to stop Kuroda if he lands clean, but we do favour the champion to retain his title in a really compelling affair.
