Extreme heat and inclement weather are likely to come under the spotlight as global media outlets gather here over the next four days for the Tokyo 2020 World Press Briefing.

It is the second such briefing held by Japanese officials and issues relating to extreme heat, venue operations, lessons learned from test events and transportation are all on the agenda for the conference at Tokyo Big Sight.

The four-day press briefing is due to start tomorrow with a presentation from Tokyo 2020 into media operations, covering venue press operations, technology, accreditations and transport.

Time has also been set aside though for updates on the Torch Relay, a presentation from the International Olympic Committee (IOC) and Tokyo Metropolitan Government.

With just nine months to go until the Opening Ceremony on July 24, questions relating to heat countermeasures and contingency plans for inclement weather following last weekend's Typhoon Hagibis are expected to be addressed.

Typhoon Hagibis left a trail of destruction across Japan, with 53 lives lost in torrential downpours, landslides and subsequent flooding.

Japanese news agency Kyodo reported earlier today a further 38,000 people across 17 prefectures had evacuated from their homes in the last 72 hours.
