In theory we could have an Asia/Tokyo-2020-Olympics zone but I'd rather not, as 
it doesn't fit into the naming scheme. (Heh, maybe it should be 
Games/Olympic/2020 instead....)

I suppose we'd create a new zone Asia/Osaka that would eschew DST.

I looked into the English-language coverage and my impression is they're leaning 
towards "no". 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 the meantime, starting times seem to be mutating a bit. The triathlon start 
has moved from 10:00 to 08:00. 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.
