The history between the two men is now 9 years old, with the two men having fought to a split decision draw back in 2008. That draw was in the East Japan Rookie of the Year final, and saw Hosokawa advance to the final on the “Dominant Point” rule. That result was followed by Hosokawa winning in the All Japan Rookie of the Year final, claiming the crown as the Lightweight Rookie of the Year. It's fair to say that Aso will be seeking revenge here.
Aged 31 Aso won the title in his third shot at it, following two losses in title fights against Hiroki Okada. Those losses to Okada are the most recent ones Aso has suffered, but he has also come up short against the likes of Shinya Iwabuchi and Jung Hoon Yang. Along with those losses are wins over the likes of Kazuyoshi Kumano, Moon Hyun Yun, Kazuki Matsuyama and Yusuke Konno. Through his career he has proven to be an ultra-aggressive and exciting pressure fighter fighter, who brings the action behind a tight guard and looks for a fight. Although Aso can be out fought, and out boxed, he does tend to make fights exciting and his title defense against Konno is a front runner for the best Japanese fight of 2017.
Aso's style has taken atoll on his body, and with 4 stoppage losses against his name he isn't the most durable. Despite that he seems to fight like a man who believes he can take bombs and that's part of what makes him dangerous. He heavy handed, aggressive and willing to take risks to stop opponents. He's not going to just back off because he gets caught and will instead fight fire with fire, and can be very hard to time when he's hurt.
Whilst Aso is a fighter with a tight guard and hurtful power the same cannot be said of Hosokawa, despite the fact he too is an aggressive fighter who enjoys fighting off the front foot. Hosokawa will instead march forward and let his hands fly, with a very high work rate, a great energy and a belief in simply out working and swarming his opponents. He can certainly be out boxed, and and he has been stopped in previous title bouts by the heavy handed pairing of Shinya Iwabuchi and Min Wook Kim, but even in his losses he has given opponents absolute hell. In recent years he has notched up notable wins against the likes of Jumbo Oda Nobunaga Shoten Petagine, Cristiano Aoqui and Quaye Peter and no one will begrudge him his 4th title bout here.
Aged 36 Hosokawa's huge energy reserves don't last much longer and he is certainly in the latter stages of his career. Having come up short in previous title bouts he probably knows that this will be his final shot, and it's hard to imagine him leaving anything in the tank. He may not have the power to hurt Aso, but he has the work rate to defeat him and the will to win to really give Aso hell.
What we're expecting is for the men to meet in center ring and for a 10 round, balls to the wall war. The guard of Aso will be hard for Hosokawa to break through, but he could end up handcuffing the champion with his out put. Aso's power could be the difference, and he may be able to make Hosokawa think twice about wildly working up close. Either way this is going to be a nail biting, violent and brutal contest that will have fans captivated from start to end.
