Japan ending Tokyo virus emergency one month before Olympics

The state of emergency in place in Tokyo began in late April and largely limits bar and restaurant opening hours and bans them from selling alcohol.

That measure will now end in the capital and eight other regions on June 20, Prime Minister Yoshihide Suga announced. It will stay in place in Okinawa.

"The number of infections nationwide has been declining since mid-May and the situation in terms of hospital beds is steadily improving," he said.

"On the other hand, in some regions, there are signs that the fall in the number of infections is slowing," Suga added.

In place of the emergency, the government will implement so-called "quasi-emergency" measures in Tokyo and six other areas until July 11.

The measures will allows sales until 7 pm, but still asks restaurants to shut at 8 pm.

Crucially, with just five weeks until the pandemic-postponed Games open, strict limits will remain on the number of spectators allowed at large events.

The current state of emergency allows only 5,000 people or 50 percent of venue capacity, whichever is smaller. And on Wednesday, the government approved an upper limit of 10,000 spectators, but only for areas not under any restrictions.

Those rules are likely to guide Olympic organisers when they decide in the coming days how many domestic fans, if any, will be allowed to attend.

Overseas fans have already been banned from the Games for the first time, and organisers said they would wait to rule on domestic spectators until the emergency was lifted.

The issue is controversial. While cases in Japan have fallen from their fourth wave peak, some medical professionals fear that crowds of Olympic spectators could fan a new surge.

A report expected soon from some of the government's top medical advisers will argue holding the Games without fans would be safest, national broadcaster NHK said Thursday.

The experts will urge that additional rules are imposed if spectators are allowed, NHK said.
