Organizers and the head of the International Olympic Committee's inspection team for the Tokyo 2020 Games on Wednesday said the rising costs associated with preventing heat-related illnesses and injuries to athletes and spectators due to the country's increasingly hotter summers are being factored into the budget, which they promise remains on target.

John Coates, the leader of the IOC's delegation, said at a news conference in the capital that issues surrounding weather conditions during the July to August period and transportation during the games have been primary topics of debate in recent months.

To diminish risks to the health of athletes, the organizers have decided to push back the starting times of mountain bike races by an hour. Under the proposed schedule change, the races will be held from 3 p.m. to 5. p.m.
