The Tokyo Metropolitan Government was not able to contact some 120 COVID-19 patients who were recuperating at home between July 2 and 3, amid network trouble with the country's major mobile carrier KDDI Corp., authorities revealed on July 4.

    Companies commissioned by the Tokyo government to observe the health of patients recovering at home phoned the individuals, but apparently could not reach them. They said that normally they cannot get through to around 20 people per day, and Tokyo officials believe that the recent cases were caused by KDDI's network trouble. At present, there have reportedly been no negative consequences resulting from the connection failures, such as a deterioration of patients' health.

    A similar issue has occurred in the Kanagawa Prefecture capital of Yokohama, south of Tokyo, which had been unable to contact a number of coronavirus patients recuperating at home, as of 3 p.m. on July 4. The city said it was unable to reach a total of up to several hundred patients between July 2 and 3. Municipal officials have been confirming the health state of individuals by reaching out to emergency contacts earlier registered by the patients and through other means. There have reportedly been no repercussions on patients' health.
