The US State Department has issued a “Level 4: Do Not Travel” advisory warning against travel to Japan, where Covid-19 infection rates are rising two months before Tokyo hosts the Summer Olympic Games.

Though the guidance does not specifically mention the Olympics, case numbers have been rising in Japan as the government has begun vaccinating health care workers and people ages 65 and up.

The State Department noted that travel for tourism and other short-term purposes is still not permitted in Japan. Visa-free travel is also suspended. The Centres for Disease Control and Prevention also updated a travel advisory Monday warning against traveling to Japan.

“Travelers should avoid all travel to Japan,” the CDC said. “Because of the current situation in Japan even fully vaccinated travellers may be at risk for getting and spreading COVID-19 variants and should avoid all travel to Japan.”

The agency added, “If you must travel to Japan, get fully vaccinated before travel.”

The country has had over 36,000 Covid-19 cases and 779 deaths in the last seven days and nearly 716,000 cases overall, according to an NBC News tally. Japan, where over 12,000 people have died overall, is also still under a state of emergency as it prepares to welcome 11,000 athletes from 200 nations and territories.
