The Japan Sumo Association will use "mob cams" during the Autumn Grand Sumo Tournament at Ryogoku Kokugikan stadium in Tokyo in an attempt to throw organized crime out of the traditional sport.
Determined to remove yakuza from the sport once and for all under new Chairman Hanaregoma, the JSA said Sunday that it will install security cameras at the Kokugikan for the September meet, or "basho," in consultation with the police.
