Around 86% of people in Japan are concerned about a rebound in COVID-19 cases if the Tokyo Olympics and Paralympics are staged this summer, a Kyodo News poll showed Sunday.

The two-day nationwide survey conducted from Saturday found that 40.3% believe the Summer Games should be held without spectators and 30.8% think they should be canceled.

The results demonstrate the scale of the public's doubts about holding a major global event during a pandemic, around a month before the opening of the Olympics, with 68% also viewing the Japanese government's vaccine rollout as slow.
