The 2020 Tokyo Olympic and Paralympic Games organizing committee is planning to ban smoking in and around all event venues.
The committee previously considered prohibiting smoking inside the buildings where games would be held, but setting up smoking areas on venue grounds for spectators and staff.
Now committee members are ready to ban smoking on venue grounds altogether.
The decision would be in line with International Olympic Committee and World Health Organization policies. Both groups have been promoting a tobacco-free Olympics.
Organizers are still considering establishing smoking areas inside the Olympic and Paralympic Villages, where athletes will stay.
Officials say smoking areas were available on venue grounds at the 2016 Rio de Janeiro and 2012 London Olympics and Paralympics.
Tokyo in 2020 would be the first summer games to ban smoking anywhere on venue grounds.
At the 2018 Winter Games in Pyeongchang, smoking was banned inside all venues. But a small fire was reportedly caused by smoking near a venue.
The Tokyo organizing committee will consult local authorities on the matter.
