US citizens warned not to travel to Japan as Tokyo Olympics near

(CNN) — The Tokyo Olympics, postponed in 2020 during the early days of the Covid-19 pandemic, are facing increasing hurdles in putting on a 2021 show.
The latest troubling sign for the Summer Games came Monday when the State Department advised US citizens against traveling to Japan because of a sharp increase in Covid-19 cases.

The "Level 4: Do Not Travel" advisory is the highest cautionary level in the department's hierarchy of warnings.
It's been more than a year since Americans have paid tourist calls to the nation. Japan has been closed to US leisure travelers throughout the pandemic, with only "very limited" circumstances in which US citizens could enter.
The Games are still scheduled to run from July 23 to August 8 in Japan.
Japanese chief cabinet secretary Katsunobu Kato said on Tuesday that Tokyo believes there is no change in US support for holding the Olympics despite the State Department's advisory against traveling to Japan.
"We have also received an explanation from the United States that the decision to raise the travel advisory level (to Japan) to Level 4 is not related to the dispatch of the athletes from the United States," Kato told reporters at a news conference.
#Covid-19 outbreak in Japan#
Japan has seen a big increase in Covid-19 cases, which have steadily risen since a state of emergency was lifted in March.
Its vaccine rollout has been slow compared with other places in Asia because of a shortage of medical professionals and a lack of syringes. Only about 2% of Japanese citizens have gotten at least one shot of the vaccine.
The government plans to open large-scale vaccination facilities in Osaka and Tokyo to speed up the process. The Health Ministry formally approved two Covid-19 vaccines (Moderna and AstraZeneca) on May 21.
The rollout also contrasts sharply with the US vaccination campaign, with at least 25 states now having at least 50% of its adult population fully vaccinated.
