On paper this did look like a mismatch but the challenger had been in good form, with 6 straight wins, including an upset last time out against Akihiko Katagiri. Sadly for Otsubo that form was thrown out of the window as he came off second belt time and time again against Hosono.
The champion had a slow start and may have lost the opening round. From then on however it tricky to even imagine a round that a judge could have given the challenger, who lacked the fire power to slow down the aggressively minded champion.
At the 5 round mark Hosono's domination was seen on the cards, which read 49-46 × 2 and 50-46 and by the end of the fight Otsubo had done little to close the gap with the cards reading 99-91 × 2 and 99-92.
The hope of the champion is clearly another shot at a world title. It's fair to say however that that may be more difficult than he'd have hoped, especially given the fact that the champions are, generally Western based and will have little desire in travelling to fight a nightmare like Hosono.
