Tokyo opened its doors to international competition again on Sunday, with superstar gymnast Kohei Uchimura among those participating at a meet viewed by some as a test case for whether an international sporting event — namely next year’s postponed Tokyo Olympics — can safely be held in Japan in the middle of a pandemic.

“King Kohei” was the headliner at Yoyogi National Gymnasium, as 30 gymnasts from Japan, China, Russia and the United States competed in the Friendship and Solidarity Competition.

“I think this event is a good model case for other sports and other athletes,” Uchimura said.
