Following a tumultuous week in the tennis world, Japanese players are expressing concerns about plans to relaunch both the men¡¯s and women¡¯s tours in the U.S. later this summer.

While the ATP and WTA are set to return to empty stadiums ¡ª which wasn¡¯t the case for the ill-fated Adria Tour organized by Novak Djokovic that led to a mini-cluster of COVID-19 infections among players, including the world No. 1 himself ¡ª some are wondering about the viability of holding large-scale tournaments including the U.S. Open.

Restarting amid a pandemic is particularly challenging for a sport that brings together players from all over the world ¡ª over 50 countries and states were represented in the U.S. Open men¡¯s and women¡¯s singles draws last year.
