Spectators might be allowed to bring their own bottled drinks into venues for the 2020 Olympics, marking a major departure from past security procedures, organizers hinted Thursday.
The step is among a raft of countermeasures proposed by the organizing committee to protect visitors, volunteers and athletes from the extreme heat and humidity of Tokyo's sweltering summers.
Other measures include patrols by staff with first-aid training and the installation of "cool spots" that provide shade and cooling fans.
