Details regarding Takesako's test are relative scarce though from what we understand the talented fighter, a 2-time runner in national tournaments at Middleweight, is expected to be fast tracked as a professional and will be fighting out of the World Sport gym. From what we under-stand his trainer is Toshiyuki Fujiwara, who previously took Nobuhiro Nashiro to world titles at Super Flyweight.
Whilst details of the pro-test were scant so too are the details regarding his debut, though it would seem likely that he'll be making it sooner rather than later and given his amateur credentials we suspect it'll be against a noteworthy opponent. If so we'll get to see if he's as good as touted or not.
From what we know about him he's in his early 20's and has shown solid boxing ability in the amateurs, with his performances in the Kansai league said to have been very impressive. Notably he also fought Ryota Murata, after Murata won his Olympic gold medal, in what appears to have been Murata's final amateur bout. Of course no onw is suggesting Takesako is going to have the success Murata will have, but is worth noting that he has rubbed should with some very talented fighters back in his amateur days, of which Murata is by far the biggest name.
