About the new coronavirus contact confirmation app (COCOA)


The Ministry of Health, Labor and Welfare has distributed the new type coronavirus contact confirmation application (COCOA) COVID-19 Contact-Confirming Application. This application uses the proximity communication function (Bluetooth) of the smartphone, with the consent of the user himself, to ensure privacy so that they do not know each other, and it is possible that they have come into contact with a person who is positive for the new coronavirus infection. It is an application that allows you to receive notifications about sex.

Please install the contact confirmation app to protect yourself, your loved ones, and the community and society.
