International Olympic Committee vice-president John Coates says the Tokyo Games will go ahead because organisers have designed a custom-made Olympic bubble to protect athletes and the Japanese people

Questions have been raised about the viability of the Games, with Tokyo in a state of emergency as Japan continues to struggle to contain Covid-19.

Coates told the Australian Olympic Committee's annual meeting the nation's 484 athletes should prepare to travel north for the experience of their lives.

He says the Tokyo Games will take place because every measure to protect the athletes and the Japanese people will be in place.
