Japan is making arrangements for its COVID-19 vaccination passports to be accepted by over 10 nations, including Italy, France and Greece, after the certificate program begins in late July, government sources said Sunday.

If the agreements are reached, certificate holders will be exempt from quarantine or showing negative test results for COVID-19 when traveling from Japan to those countries, the sources said.

But the Japanese government plans to continue requiring travelers entering Japan, including returnees, to quarantine for two weeks even if they have been vaccinated. The position has complicated negotiations with countries such as Singapore and Israel, which have called for mutual exemption, the sources said.
