A coast guard patrol vessel arrived at the scene at around 17:05 and found the upturned helicopter and three survivors floating on the surface. The survivors, who were found clinging to inflatable life preservers, all contracted hypothermia but were otherwise conscious.
Tragically, the deceased bodies of the female patient, a 68-year-old male companion, and a 34-year-old male doctor were pulled out of the water by the crew of a Japan Air Self-Defence Force helicopter that had also deployed to the area to render assistance.
