Who is the most big name in fact that Kosei Tanaka "Monster of Chukyo" four weight classes champion beat in his career ?
Sho Kimura probably? Although it could've gone either way. Angel Acosta and Ryoichi Taguchi were his most impressive performances, to me. There He left no doubt against world class opponents.
I'd maybe say Bomba Gonzalez considering how Bomba went on to have a very solid run at 108 right afterwards and seemed to be in the middle of his prime when Tanaka stopped him.
For me Ryoichi Taguchi is his most good performance too specially because it's a victory against the first unified Japanese champion in history. Considering that he was a former 2 times Raja Champion and former Lumpinee Champion undefeated Palangpol CP Freshmart is also a good victory too.
