Japan's women's softball team got the Tokyo 2020 Olympics off to a winning start for the hosts on Wednesday, kicking off a pandemic-postponed Games that the World Health Organization says can be "a celebration of hope" even as COVID-19 cases surge.

Olympics and Japanese officials have forged ahead with the sports spectacle despite opposition in the country to hosting more than 11,000 athletes, staff and media — dozens of whom have already tested positive.

Spectators have been barred and restrictions have been imposed in and around Tokyo in an effort to minimize health risks among residents and visitors.
