Japan has been struggling since late March to slow a wave of infections propelled by more contagious variants, with new daily cases soaring above 7,000 at one point and seriously ill patients straining hospitals in Tokyo, Osaka and other metropolitan areas.
Daily cases have since subsided significantly and Prime Minister Yoshihide Suga is expected to downgrade the state of emergency when it expires on Sunday to a less-stringent quasi-emergency for several weeks.
Despite concerns raised by medical experts and the public over the potential risks of holding the Olympics, Suga has said he is determined to hold a “safe and secure” games starting July 23.
Government-appointed experts met Wednesday to analyze the situation ahead of Suga’s decision on the emergency measures and expressed concern about the potential for infections to climb again after measures are eased. Suga is expected to make a final decision Thursday after more meetings.
Ryuji Wakita, the director-general of the National Institute of Infectious Diseases who heads a government COVID-19 advisory board, said infections have decreased in many areas, but the slowing has bottomed out in the Tokyo region. He warned that infections could increase after an easing of the measures. He said signs of a rebound are already seen among younger people.
Even as more people are vaccinated and most of the country's 36 million senior citizens are expected to be fully inoculated by the end of July, younger people are largely unvaccinated and infections among them could quickly burden hospitals, Wakita said.
“In order to prevent another upsurge, it is crucial to prevent the people from roaming around during the Olympics and summer vacation,” he said.
Experts say it is crucial to accelerate the vaccine rollout to hold the Olympics safely in one of the world's least vaccinated developed countries, .
Suga has opened up mass inoculation centers and started vaccinations at major companies, while setting an ambition target of as many as 1 million doses per day.
As of Tuesday, only 5.6% of Japanese were fully vaccinated.
With vaccination rate still low, experts are concerned about the increased flow of the people in Tokyo despite the emergency. Many residents have become impatient and are less cooperative with social distancing requests, they say.
In hard-hit Osaka in western Japan, hospital capacity has improved and new infections dropped to 108 on Tuesday, significantly down from more than 1,200 a day in late April.
In Tokyo, new infections are down to around 500 per day from above 1,100 in mid-May. Tokyo Gov. Yuriko Koike has said effective virus measures need to be kept in place.
