I_cycle,
Network Connection Error
If you want to (or must) use the Exposure Notification system on iOS in Japan, you must use this app. If you attempt to register in the app before you arrive, you will get an unhelpful “Network Connection Error”.
The app will not let you proceed unless you are connected via a Japanese network. Note that international roaming on a foreign cellular network will not work. You must connect via a WiFi network in Japan or via a Japanese cellular network.

yoyookhss,
Network connection error issue resolved
A lot of people in reviews comments they have network connection error after accepting terms of use. The Japanese Ministry of health website said you cannot use it if you are not in Japan. I assume you will be able to use it once you landed in Japan.
I hope this helps many of you having this issue.

Molanda Zu,
Needs verification
Thank you for providing the app.
A major limitation is the lack of any feedback that the app is functioning properly and recording close contacts. It is like having a smoke detection without a test button.
I believe showing a count of recent contacts over a period of time does not raise any privacy concerns while at the same time adding a bit of confirmation.

TDY42,
Nobody checked if this app was installed before entering Japan
I just came back to Japan, and the government webpage asked everyone to install this app. I had the same issue with network connection, and a bit worried if it would affect going through the immigration process.
However, at the airport they did not check if this app was installed. They checked another app, MySOS, but didn’t care about COCOA. I guess they know this app is full of problems and useless.

Pismo Guy,
App restarts and loses data
I have had this app 2.5 months. I’ve noticed 3 times now that when I periodically enter the app, it acts like I have never used it before. This causes my contract tracing to begin again, as shown by the day counter. This app is completely unreliable. I don’t recall the day counter ever reaching a suitable number like 13 or 14 days, because it asks me to accept the terms again. This app is glitchy software and completely defeats the intended purpose.
Murphy in Guam,
Not enough
I wish this app was paired with more functionality. Contact teaching is okay, but unless use of this app is mandated for those people who have tested positive, it will just give us a false sense of security. How about a map showing where all infected people have been? How about real time updated stats showing infection numbers and trends? This seems to be a bare minimum effort towards placation.
washutsyhh,
Good start
The app is very easy to use and has great English explanations. However, the screen grabs they use for examples are all in Japanese. It may be beneficial to change these to English and Chinese, whichever preferred language is selected. As of now, this is a good start for a contact tracing app and hope the government of Japan works on improving it with time.
jwsredragon,
Error for registration
Mine cleared up the next day and I was able to get everything working prior to departure. Make sure that your device is running the latest firmware update.

Network Connection Error
Due to travel restrictions because of Covid, you are required to download and use this app but you can even pass & agree to the “Term of Use” -
“Network Connection Error”. Nothing is wrong with the connection. Everyone seems to have the same problem…

KevinTracy,
It doesn’t even ask for location information
How is it supposed to trace when it doesn’t even ask for information…more does it list how many checks it’s made. It could have been promising but like most things covid related in japan this is an absolute failure.
