The Tokyo Olympic Games are upon us. They look and feel different to any other Games of times gone by, but they are here. At last.

With an unexpected additional year of preparation under their belts, more than 11,300 athletes from 207 countries will compete over the next couple of weeks, all vying to get their hands on the medal they've worked so long for.

When the Games were postponed in March 2020, organisers said the Olympic flame "could become the light at the end of the tunnel". With the Covid-19 pandemic still raging worldwide, that metaphorical tunnel is still being traversed, but Friday's opening ceremony offers a glimmer of that light.

"I think it will be a moment of joy and relief when entering the stadium, a moment of joy in particular for the athletes because I know how much they are longing for this moment," said International Olympic Committee president Thomas Bach.

"Then they can finally be there, they can enjoy this moment under very special circumstances."
