U.S. military bases in Japan introduced stricter COVID-19 measures on Thursday after the host government expressed grave concern about a surge of new infections and called for restrictions on the movement of U.S. personnel. Three prefectures that host U.S. bases have requested quasi-emergency measures as Japan faces what some are calling a sixth wave of coronavirus infections, with cases in some places at their highest in months. One official has blamed U.S. military personnel for spreading the Omicron variant.
U.S. Forces Japan said that due to an increase in COVID-19 cases at installations and throughout Japan, it was establishing more stringent measures, including requiring personnel to wear masks off base and stricter testing.
“The mitigation measures we have instituted…are intended to protect our force’s readiness, the well-being of our families, and the health of Japan’s citizens,” the force said in a statement.
“We recognise we all have a part to play in keeping our communities safe.”
More than 100,000 U.S. service members, dependents and contractors are stationed in Japan.
Earlier, Foreign Minister Yoshimasa Hayashi asked U.S. Secretary of State Antony Blinken for restrictions on U.S. service members from leaving their bases, Chief Cabinet Secretary Hirokazu Matsuno told reporters.
Matsuno said Japan was “gravely concerned” about COVID-19 infections at U.S. bases.
Nationwide, new infections surpassed 4,000 on Thursday, according to a tally by national broadcaster NHK, the most since Sept. 18. Tokyo reported 690 cases, up from 390 on Wednesday, and an expert panel said about 45% of infections in the capital were due to Omicron. Japan’s total death toll from the pandemic stands at 18,397 people.
The southern prefecture of Okinawa, host to 70% of U.S. military facilities in Japan, is at the epicentre of Japan’s latest surge of cases, and it asked the central government on Thursday to impose new restrictions, known as quasi-emergency measures, which were likely to include limiting the opening hours of restaurants and bars.
Announcing the request, Okinawa Governor Denny Tamaki said new cases there were expected to surge to about 980 on Thursday from 623 the day before.
Tamaki told reporters this week he was “furious” about what he called inadequate infection controls at U.S. bases that allowed the Omicron variant to spread to the public.
The western prefectures of Hiroshima and Yamaguchi, which also host U.S. military facilities, said they would also request similar measures. Various levels of emergency controls had been in place over most of Japan last year until their lifting on Sept. 30.
Japan halted the entry of almost all foreign travellers in late November after the World Health Organization listed Omicron as a variant of concern.
But the U.S. military moves staff in and out under a separate testing and quarantine regime.
A U.S. Marine Corps station in Yamaguchi prefecture said on Thursday it discovered 115 new cases, after 182 announced the previous day.
