In November 2012, Arakawa competed with Mexican Pedro Daniel Estrada in Mexico City on the main event of the "Gala Ring Telmex 2012". It was a WBC Silver lightweight title bout and was a title eliminator with a shot at Adrien Broner on the line. After eleven rounds, Estrada was called as the winner with a technical decision. Its refereeing processes and outcome caused controversy in Japan, and more in Mexico. The WBC's official Twitter account tweeted as follows: "There was a controversy in that fight where the winner would be fighting for the title, but because there was this problem, the WBC demanded a rematch. That is a fight for all ring officials to look at." A rematch between them never happened.
