Health Minister Katsunobu Kato has disclosed plans to step up measures at ports of entry from China to prevent the spread of infections caused by a new strain of the coronavirus.
Questionnaires about symptoms will be distributed to passengers arriving on flights from Wuhan, China, where the deadly outbreak began.
Announcements will be made on flights from Shanghai, asking passengers to inform staff if they have a fever or other symptoms.
Kato told reporters after a Cabinet meeting on Tuesday that the World Health Organization is set to hold an emergency meeting on the outbreak.
He said he intends to take the results of the meeting into account and work with relevant offices according to the changing risks to ensure that thorough preventive measures are in place.
