Japan plans to set up new testing centers for the novel coronavirus outside three major airports in Tokyo and Osaka, as well as in central parts of the cities, as the country prepares to relax its travel restrictions, a government official said Thursday.

The facilities, intended mainly to test people entering the nation from abroad, are to be built near the airports — Haneda and Narita near the capital and Kansai in Osaka Prefecture — as soon as this summer, the official said.

The government has yet to decide whether to use them for those in Japan who may require evidence they are virus-free to travel outside the country.
