For instance there was the discussion around the marathon, where runners would be at serious risk when running outdoors in the middle of the summer in Tokyo. Yet it took months and months of discussions, stupid alternatives (including "let's change Tokyo's time during the Olympics so the marathon starts at the planned time, but it would actually be super early morning when the sun is still low") to finally move it to a place where people won't be dying.
The current administration is well above caring for public safety, but we can hope the international outcry will be huge enough of a threat to force their hand.
