Despite pledges to self-isolate upon arrival in Japan, up to around 300 people daily may be breaking quarantine, the health ministry and a contracted medical service firm said Saturday.
Daily checkups have been conducted as part of strengthened border control measures since the end of March to keep imported cases of the coronavirus at bay. All arrivals into the country are subject to the checks for a 14-day period after entry.
But because the ministry has been unable to confirm the whereabouts of some people during the period, it is now considering having private security companies visit quarantine locations if an individual cannot be reached for more than three days.
