Japan is making final preparations to shorten the period of quarantine for people fully inoculated against COVID-19 from 14 to 10 days and allow them to immediately self-isolate at home, even when returning from higher-risk locations, the health ministry said Friday.

The change will most likely take effect from October, according to reports citing government sources.

Following the planned change, those who present proof that they have been fully vaccinated against COVID-19 will be able to observe the shorter quarantine period at home. It is not yet clear what will constitute acceptable evidence, although Japan and other nations have begun issuing vaccine passports for overseas travel.
