Japan's minister in charge of coronavirus measures, Yasutoshi Nishimura, has proposed limiting spectators to 10,000 at major events, Jiji Press reported on Wednesday, ahead of a decision scheduled for this month on the number of domestic spectators allowed to attend the Summer Olympics.

Large venues in the capital, Tokyo, are now allowed only up to 5,000 spectators or half their capacity, whichever is lower, as part of virus curbs that run until June 20, the prefecture's government says.

The Olympic Games, delayed a year by the pandemic, is set to start on July 23.
