Dai Tamesue, a former sprinter who represented Japan at three Olympics, said Monday he remains unsure whether the Tokyo Games should go ahead this summer amid the coronavirus pandemic.

Tamesue, a two-time bronze medalist in the men's 400-meter hurdles at the world championships, said he feels conflicted because he knows the hardships athletes have gone through to prepare for the Olympics, but the games have also had a great impact on Japanese society.

"As a former athlete, I want the (Olympics) to be held, but when I think about it calmly, I am not sure what the right decision is," he told a press conference at the Japan National Press Club.
