The tag alias #52386 2020_tokyo_olympic -> 2020_tokyo_olympics has been approved.
Reason: That's how you spell it.
You could make an argument for 2020_summer_olympics or 2020_tokyo_summer_olympics, but I don't think that's important. The city name is important since it helps you to quickly recall the mascots.
It has been delayed by a year due to COVID, but it is still officially branded as 2020.
