I saw this on NBC News – Heat wave hits Tokyo as Olympic organizers battle to keep Covid rates down: https://www.nbcnews.com/news/olympics/heat-wave-hits-tokyo-olympic-organizers-battle-keep-covid-rates-n1274899. Longer article, but my question is why didn’t Tokyo do what it did in 1964 by switching it to October? Look like some events were moved to Sapporo.

The Tokyo Olympics organizers, already struggling to contain the spread of Covid-19, are contending with another obstacle largely beyond their control: a heat wave.
Day after day of 90-plus-degree heat and high humidity has forced organizers to reschedule rugby matches and mountain biking competitions and move some track and field events to early morning hours or dusk to avoid the roasting afternoon sun.
Other events, like the marathon and race walking, have been moved completely out of Tokyo to the cooler city of Sapporo, capital of the mountainous northern Japanese island of Hokkaido and the site of the 1972 Winter Olympics.
