For those who haven't seen Aso his style is the typical Japanese warrior style. He comes to fight, presses the action and always looks to have a fight. Sometimes that costs him, such as in his 2011 bout with Shinya Iwabuchi, but other times it sees him out battling and breaking fighters down, as he did against Matsuyama. It's a style, and mentality, that makes for fun action fights but has taken it's toll on him and his body isn't as tough and durable as it perhaps needs to be if he's to have a long career.
Although not a huge puncher Aso can bang, but often finds himself being dragged into wars of attrition, which is partly why he has been such a popular fixture at the Korakuen Hall over the last 11 years or so. During that 11 year career he really has faced almost everyone of note at the domestic level, including Valentine Hosokawa, Taisho Ozawa, Shinya Iwabuchi, Jung Hoon Yang, Moon Hyun Yun and Hiroki Okada, twice. He's generally struggled against the best domestic level foes, but has shown he belongs in there, and he has developed with experience.
Although Aso is well known and experienced at the top of the domestic tree the same cannot be said of Konno. In fact Konno's most notable bouts to date have all resulted in losses, with defeats coming to the likes of Hisao Narita and Kazuyoshi Kumano. To date his best wins have been over the likes of Kazuya Soma and Shusaku Fujinaka, which are decent wins but nothing outstanding.
Footage of Konno as easy to get as it is for Aso, and as a result it's harder to get a read on his style, but he's yet to be stopped, and has shown an ability to fight over 8 rounds at a good rate. This will however be a marked step up in class, and be his first over 10 rounds. Those two things alone will be a huge challenge for the 32 year old Kanagawa born fighter.
It's likely going to be a fun fight, and one fought at a high pace, but we suspect that Aso's extra experience will be the difference, with the champion coming out on top with a late stoppage, in a very fun and competitive bout.
