One month before the sixth world title tripleheader for Teiken Promotions in April 2011 , Honda unofficially announced two plans in the mid-2011 for Akifumi Shimoda and Toshiaki Nishioka to fight in the United States . Soon after that , Tōhoku earthquake occurred . Confirming the intentions of all participating boxers in that tripleheader , Honda considered their safety at the top priority . Then , preparing for the blackout , he made effort to secure by themselves the necessary minimum electric power for the live telecast and for operating the venue facilities , in consultation with Nippon Television which would broadcast the fights . However , he decided to refund all previous tickets and change the venue from the Ryōgoku Kokugikan in Tokyo to the World Memorial Hall in Kobe , Hyōgo for the risk management . That tripleheader event was relayed in the United States , Argentina , Italy and other countries , in addition to Japan 's NTV and Mexico 's Televisa
