Japan is planning to scrap a negative coronavirus test requirement for arrivals from China due to a low rate of positive results during sample testing at airports, a government source said Thursday.

Under the eased rules, possibly to go into effect from early April, travelers from mainland China will no longer have to show proof of a negative coronavirus test taken 72 hours or less before departure as long as they have had at least three doses of a COVID-19 vaccine, the source said.

At the end of last year, the Japanese government implemented blanket COVID-19 testing for all arrivals from mainland China, applying to those who had visited the country within the previous seven days.

In early January, it further tightened border controls for visitors from mainland China by requiring proof of a negative test.

In March, however, the government switched to testing only passengers on selected flights from China after finding that the number of those testing positive for COVID-19 had dropped.
