Entering as the champion Nakagawa has a lot more to lose than to gain here, however the 31 year old won't be thinking about losing, but instead he'll be focused on defending his crown.
In the ring the champion is a bit of a crude slugger, he's not out and out wild, but he does have rough edges in terms of his boxing ability. Those rough edges will probably holding him back from becoming an OPBF champion, but they are are the typical edges you see at domestic level. They are, however, coupled with spiteful power which can shut down fighters offensively, or at least make them cautious enough to think twice about opening up.
Not only is Nakagawa a heavy handed fighter but he's also a tough fighter, who can take a solid shot to land his own. That was shown against Kimura, who landed a fair bit of his own leather but was put on the back foot frequently, and has been shown against other decent foes. It's also worth noting that since progressing beyond 4 rounders Nakagawa is unbeaten, going 9-0-1 (7) in bouts scheduled longer than 4 rounds. It is, however, worth noting he has only been beyond 4 rounds twice, going 2-0 in those bouts, with his power being particularly potent in the first 4 rounds.
Entering as the mandatory challenger Funai will be seeking his biggest win to date, though it will be his third shot at a title having previously fallen short in an OPBF title fight against Rolly Lunas and a Japanese title fight to Sho Ishida last year. One other notable loss on his record was a 7th round loss in 2009 to Shinsuke Yamanaka. It's also worth noting that 2 of Funai's other losses were in his first 4 bouts, when he was a real novice.
In the ring Funai is tougher than you'd expect, given he has been stopped 3 times, he's technically sound and has a good engine, in fact he gave Sho Ishida absolute fits late in their bout. With 18 stoppages in 26 wins he's a solid puncher, but isn't a massive puncher, and although he can hurt fighters his most notable stoppages have been against the likes of Ryuta Otsuka, Masafumi Otake and Teppei Kikui, though decisions over Gakuya Furuhashi and Akinori Hoshino are good decision wins.
It's also worth noting that the Watanabe gym, who manage Funai, are having a year to remember. They have seen Nihito Arakawa, Yusaku Kuga and Hiroto Kyoguchi win titles already this year and that type of success and bred more success, driving on the likes of Funai on to perform better.
Both men are over-looked domestically, but both are very solid domestic type fighters, and both will be fighting with a point to prove. For Nakagawa the point to prove is that he deserves the title whilst, and that he should be viewed as the best on the domestic scene. For Funai it's that he deserves to win a title before his career is over, it's that he deserved a third shot and that he is worthy of becoming a champion, rather than another also ran.
Sadly for Funai we don't think this will be his night. We think the power and aggression of the champion will be too much and that he will, eventually, wear down Funai in what will be an exciting, and action packed bout with plenty of exchanges, but with those exchanges ending in favour of Nakagawa, who we think will stop Funai in round 9 or 10.
