Question

In March 2021 the International Olympics Committee (IOC) enabled athletes from which country to compete at the Tokyo Summer Olympics (rescheduled from 2020) provided it was under a neutral flag instead of the flag of their own country?

Answer 1

Miu Goto, softball
The Mayor of the town she was visiting had publicly asked to hang her medal round his neck, removed his COVID-19 mask, and bitten the medal (reportedly leaving tooth marks). The IOC offered a replacement, which she accepted. The Mayor's actions were heavily criticised in Japan and internationally.
