A task force created by the Ministry of Land, Infrastructure and Transport has compiled a list of recommendations for measures to deal with high road temperatures during the 2020 Tokyo Olympics and Paralympic Games. For events such as the marathon and race walking which make use of roadways, "heat shield pavement," material sprayed onto the road surface to reflect sunlight and thereby help prevent its temperature from rising, is being actively introduced. In August the Ministry verified the difference in road surface temperature due to the new material, finding a consistent temperature reduction effect where the "heat shield pavement" was used. Once the Olympic courses have been finalized, the Ministry plans to further push the new pavement material.
