6.About monitoring of health condition

Questions Answers
6-1

Why is it necessary to monitor health condition for the designated 14 (or 7) days?

Even if you have tested negative for COVID-19, you may later develop symptoms. The World Health Organization (WHO) indicates that the incubation period for this disease is 1 to 14 days (typically about 5 days), and based on available information about the coronavirus, it recommends monitoring health condition for 14 days. However, the quarantine period is seven days for someone entering Japan from a country that has many reported cases of infection from the omicron variant. This has been decided based on scientific expertise in Japan. We ask you to monitor health condition daily to enable a rapid response in the event you develop symptoms.

Regarding reporting of health condition, if no response is received within a certain time after a push notification, a reminder will be sent again via push notification on the evening of the same day.

If no response has been received for a certain period of time, upon review of circumstances, anyone deemed to have failed to report health condition or location, etc., without a valid reason may have their name publicly disclosed (and nationality, in the case of foreign nationals), as well as other information that may help prevent the spread of infection. Foreign nationals may be subject to revocation of their status of residence and deportation under the Immigration Control Act.

I don't receive any push notifications to report my health condition. What should I do?

If you have not received any push notification within two or three days after entry in Japan, the information currently registered in the app may not match the information registered at the HCO, so please open the app, tap on "Registrant Info", and confirm that the displayed passport number and date of birth are correct.
To see how to confirm your registered account information please see below for details.

Prior to that I did not receive any push notifications, I only receive a reminder notification, so how should I reply?

Depending on the timing of your registration in our system, on the day after your entry to Japan the first push notification to confirm health conditions could arrive in the evening in some cases. Also, in some cases, you may receive a reminder notification before that first notification. In any case, there will be no problem if you respond by confirming your health condition as directed in either notification.

If I had close contact with COVID-19 onboard my aircraft, will I receive some kind of notification?

If it is found that you had close contact with COVID-19 on the aircraft, you will soon receive a push notification via the Health and Location Monitoring App (MySOS). Pay extra attention to your health condition, and if you notice any change in your condition, please promptly contact the local Public Health Office or local government's 24-hour COVID-19 call center.

I don’t know how to handle video calls.

Once you have installed the app, no other special actions are required for video calls, except to answer when you receive an incoming video call. For instructions on how to answer a call, please refer to the HCO website, or check the "To Anyone Entering/Returning to Japan" brochure you should have received at the airport. The HCO website includes instructions.

What if I can't answer a video call?

If you do not answer a video call, the HCO may contact you by e-mail or other means.
You cannot call back on a video call.

The purpose of confirming your location by video call is to verify based on your surroundings that you are indoors at your accommodations at the time the HCO contacts you.
Since the HCO cannot verify this if you call back by telephone, please wait for the next video call if you miss one.
You do not need to make a call back to the HCO.

If you do not know how to answer a call, please refer to the HCO website, or check the "To Anyone Entering/Returning to Japan" brochure you should have received at the airport.
The website includes instructions on settings and how to use the apps.
Also, please go to the settings on your smartphone, and confirm that your phone is set to allow notifications from the app.
Anyone who violates the written Pledge (failing to report health condition or location, etc.) without a valid reason may have their name publicly disclosed (in the case of foreign nationals, name and nationality), as well as other information to help prevent the spread of infection.
Foreign nationals may be subject to revocation of their status of residence and deportation under the Immigration Control Act.

I received a video call. It was not from a person but just a message displayed. What was that?

Besides video calls from our operators, we use automated calls that display messages with no sound.
Please follow the instructions displayed on the screen, so your camera takes an image that includes your background.
The HCO will verify via video call that you are indoors at your accommodations.
