Japan started accepting applications for “vaccine passports” Monday, with the business community and travelers welcoming the fact that the documents will exempt them from border control measures, including mandatory quarantines, in some countries.

The official documents, which have been introduced nationwide, will initially be accepted by Austria, Bulgaria, Italy, Poland and Turkey, where holders will be exempted from quarantine measures and additional tests for COVID-19 imposed on those without proof of inoculation. The document can also help with applications for exemption from quarantine requirements in South Korea.

Japan is negotiating with other governments on expanding use of its vaccine passports.
