Hosokawa, who won the title earlier this year when he upset Tadashi Yuba, isn't one of the big names of Japanese boxing, even domestically, though he is a man on a good run. He has won his last 3, with the victory over Yuba being the most notable, and has won 7 of his last 8 with his only loss in that series of fights coming to Akio Shibata, the current unified Japanese and OPBF Middleweight champion.
Whilst Hosokawa is in the form of his life it's also fair to say that Nonaka is in good form as well. He has won his last 6 and, like Hosokawa, is unbeaten since a losing effort against Shibata. The most recent of those victories came against Ryo Okayama on May 6th and after that bout it seemed only a matter of time before a deal for Nonaka to fight Hosokawa would be thrashed out. As it turned out it took just a week for all the agreements to be made.
This bout has been scheduled for August 10th and will take place at the Sumiyoshi Ward Center.
