A worker at a Tokyo Olympics construction site was found unconscious Thursday and was later confirmed dead at a hospital, the Tokyo Organizing Committee said, with police saying heatstroke may have been the cause.
Soaring temperatures have killed at least 57 people across the country since late July, highlighting the health threat to athletes and fans that is one of the biggest challenges for Olympics planners.
The 50-year-old construction worker who had been laying cables outside Tokyo Big Sight, which is being renovated to serve as the media center for Tokyo 2020, was found unconscious at around 2 p.m. on Thursday, the committee said.
