Relief from the intense summer heat could be on the way in time for the Tokyo 2020 Olympics and Paralympics in the form of “mist shower” outdoor cooling systems.

Two Tokyo universities and electronics giant Panasonic Corp. have teamed for a demonstration experiment to test the effects of one of the devices on the human body.

If the mist shower is proved effective, the Japan Sport Council, the Tokyo metropolitan government and other groups plan to set up similar cooling devices around the new National Stadium and other competition venues at the Games.

The group, consisting of the University of Tokyo, Tokai University and Panasonic, has set up a mist shower in the premises of the University of Tokyo’s Institute of Industrial Science in Tokyo’s Meguro Ward, where 100 people will allow their bodies to be gently engulfed by cool vaporized water in the largest experiment of its kind ever conducted.

“We expect that people will be able to spend time comfortably even in hot outdoor environments including sports competition venues and bus stops,” said Ryozo Ooka, a member of the project team and University of Tokyo professor specializing in urban energy engineering.

According to Ooka, such experiments testing the mist showers’ cooling effects and the comforts they bring people are almost unprecedented.

In a 2017 preliminary experiment that the team conducted on nine people, the mist shower had an effect of reducing skin surface temperature by 1 degree, according to Ooka. In the current experiment, the team will examine more details of the effects, gathering data from 100 people.

Panasonic said that if the effectiveness was confirmed, the firm will consider developing temporary devices that could be used at the Tokyo Olympics.
