In a life-threatening moment, Maizuru Mayor Ryozo Tatami suddenly collapsed while delivering a speech during a sumo exhibition in Kyoto.

He was having a stroke. Several men rushed to the dohyō (ring) to help, but they appeared at a loss over what to do.

Seconds later, a woman ran up from the audience and immediately started giving the mayor CPR. She probably didn't expect her actions to spark a national debate on the controversial traditions of the sumo world.
