Tokyo 2020 organisers say they will be ready to host the Olympic Games – despite the city declaring a state of emergency over Covid-19.
The rescheduled Games are set to take place between 23 July and 8 August.
Japanese Prime Minister Yoshihide Suga said there was a “sense of crisis” as he announced emergency Covid-19 plans.
Organisers said: “This declaration of emergency offers an opportunity for Tokyo 2020 to plan for a safe and secure Games this summer.”
Tokyo recorded 2,447 new Covid-19 cases on Thursday and the latest measures primarily target restaurants and bars, which will be asked to stop serving alcohol by 7pm and close an hour later.
