Although Toshiro Muto, director-general of the organizing committee, says that DST is "the only way" to deal with the heat, Prime Minister Shinzo Abe said only that DST "may be a solution" and Chief Cabinet Secretary Yoshihide Suga (the Number 2 in Japan) said that DST would "have major impacts on people’s daily lives". My favorite was Akira Koike, the head of the Japanese Communist Party, who said in a Monday news conference that DST will "send Japan into turmoil as adjustments would be needed for computer systems and many others".

In other news, trees are being planted along the marathon course for shade, and a layer of solar heat-blocking pavement will be put on roadways. I'd never heard of solar heat-blocking pavement until today.

Not time related, but anyone else wondering "What? How?" for heat blocking road surfaces:
Summary: high albedo for near infrared, low albedo for visible.
