Japan will make a health questionnaire available online that travelers are required to fill out before entering the country to streamline the immigration control process, sources familiar with the matter said Saturday.

The online questionnaire, meant to flag travelers who are possibly at higher risk of arriving while infected with the coronavirus, will be available soon on a trial basis for some international flights arriving at Narita Airport near Tokyo, they said.

The questionnaires are currently handed out to travelers aboard inbound flights.
