The bout saw Nonaka take control of the contest earlier before forcing the referee to save Okayama from further punishment as the former champion went to work with a vicious assault. For Okayama this was his third stoppage loss, and his second successive loss following an opening round defeat last time out to Koji Numata.
Whilst it was a major set back for Okayama the victory appears to be a launch platform for Nonaka who seems likely to be rewarded with a Japanese Light Middleweight title fight against Takayuki Hosokawa later this year.
For Hosokawa a bout with Nonaka would be his first defence since winning the title from national legend Tadashi Yuba, whilst for Nonaka it would be his first title fight since 2009 and at 36 years old it could well be his final career bout.
