A typhoon devastated parts of Tokyo on the same day as the Ready Steady Tokyo karate test event.
It has raised concerns for the Tokyo 2020 Organising Committee with just 10 months to go until the city hosts the Olympic Games.
But Yasuo Mori, deputy executive director of Tokyo 2020’s Games operation’s bureau, insisted the Organising Committee would be ready to tackle any possible effects should a typhoon occur during the Games.
