Japan is developing a system aimed at keeping track of travelers from overseas as part of efforts to prevent the further spread of the novel coronavirus within its borders, a senior government official said Sunday.
"There will be no point if we don't implement it so that you will not be allowed to enter the country unless you use it," Takuya Hirai, digital transformation minister, said on television.
Hirai said the government wants to complete the development of the monitoring system by the rescheduled Tokyo Olympics and Paralympics, due to be held next summer.
Without providing in-depth detail, he said it will function by using global positioning system technology.
His comments on Fuji TV's "The Prime" news program came a day after Japan said it will ban nonresident foreign citizens from entering the country, which has been seeing record daily numbers of coronavirus cases in recent weeks.
The measure, which will take effect from Monday through January, was announced following Japan's detection of a new and seemingly more contagious variant of the virus.
Among other measures to tighten its borders, Japan will require its nationals and foreign residents to quarantine for two weeks, show proof of a negative coronavirus test result within 72 hours of departure for the country and undergo another test upon arrival.
