TOKYO — With the emergence of the new Omicron variant of the coronavirus late last week, countries across the globe rushed to close their borders to travelers from southern Africa, even in the absence of scientific information about whether such measures were necessary or likely to be effective in stopping the virus’s spread.
Japan has gone further than most other countries so far, announcing on Monday that the world’s third-largest economy would be closed off to travelers from everywhere.
It is a familiar tactic for Japan. The country has barred tourists since early in the pandemic, even as most of the rest of the world started to travel again. And it had only tentatively opened this month to business travelers and students, despite recording the highest vaccination rate among the world’s large wealthy democracies and after seeing its coronavirus caseloads plunge by 99 percent since August.
Now, as the doors slam shut again, Japan provides a sobering case study of the human and economic cost of those closed borders. Over the many months that Japan has been isolated, thousands of life plans have been suspended, leaving couples, students, academic researchers and workers in limbo.
United States, Britain and most of Europe reopened over the summer and autumn to vaccinated travelers, Japan and other countries in the Asia-Pacific region opened their borders only a crack, even after achieving some of the world’s highest vaccination rates. Now, with the emergence of the Omicron variant, Japan, along with Australia, Thailand, Sri Lanka, Singapore, Indonesia and South Korea, are quickly battening down again.
