NHK has learned that the Japanese government will tighten temporary border controls on travelers from mainland China amid the spread of coronavirus infections there.
Government sources say the tighter measures will be introduced on Sunday. The decision was based on the infection situation in China during the year-end and New Year holidays, and border restrictions placed by other countries.
The current measures require all travelers from mainland China to take simple antigen tests upon arrival in Japan. Those who test positive are required to stay at quarantine facilities.
Under the new plan, arrivals from mainland China will be required to undergo more accurate quantitative antigen or PCR tests. Travelers on direct flights from the mainland will also need to show a negative test result.
The government will continue to ask airlines not to increase the number of flights between Japan and mainland China.
The sources say government officials plan to respond flexibly while monitoring the situation in China.
