Akaho was forced to pull out after problems making weight, in fact he was so dehydrated that he provided a doctors note and mentioned various ailments he been suffering as a result of weight loss, including numbness in hands and feet as well as headaches. He also acknowledged that he was ashamed of his the problem that had forced the bout to be cancelled and apologised to fans and Shiraishi.
The bout was supposed to be a rematch of a bout from December 2011, a bout that Akaho won by 9th round TKO to retain the OPBF Super Flyweight title.
As a result of Akaho's issues with weight we've seen the Light Middleweight bout between Yuto Shimizu (10-2-2, 3) and Maxi Nahak (4-10-2, 1) moved up to the main event. The bout, which is thought to be a warm up bout for Shimizu before a potential Japanese title fight next year, is unfortunately a much less interesting bout than the Akaho/Shiraishi bout.
