Safety App on your phone

An App for your mobile phone


In Japan, an early instant warning system called J-Alert delivers warning information directly to your phone.

However, the message is in Japanese, so to receive the message in a different language, there is an App that you can install on your phone called "Safety Tips"

This push-enabled app pushes alerts about earthquake early warnings, tsunami warnings, and other weather warnings and civil protection information within Japan in 15 different languages, as shown below.

English Simplified Chinese Simplified Chinese Korean
Japanese Spanish Portuguese Vietnamese
Thai Indonesian Tagalog Nepalese
Khmer Burmese Mongolian  

The app provides various functions useful for both foreign residents and tourists in Japan, such as an evacuation flowchart showing actions to be taken in the light of surrounding circumstances, helpful phrases for obtaining information from the people around, and website links that contain helpful information in the event of a disaster.

Below is the list of available functions.

Earthquake Early Warnings Tsunami Warnings Weather Warnings Eruption Notices
Heatstroke Information Ballistic Missile Launch Civil protection information Evacuation Advice

We strongly encourage you to install this App on your smartphone since it is extremely useful for your safety.

You can download the App here.


If you need help with installing, the Resource Center will support you.

Information from Emergency Response Coordinator

A J-Alert was issued in Okinawa Prefecture early in the morning of May 31, 2023, and we would like to let you know about J-Alerts and our responses to them. 

Suppose an intercontinental ballistic missile or other such device is launched and may fall on or pass through Japanese land or territorial waters. In that case, the Japanese government's J-Alert (Japan Alert System) will alert people through outdoor speakers and other means. People will also receive an emergency alert on their mobile phones. Stay tuned to TV or radio. Information may be available in English through TV and radio, such as NHK and AFN Okinawa. Missiles may take less than 10 minutes to reach Japan after being launched. Please stay calm and take the following actions both on and off campus. 

  • If you are outside: Evacuate to a sturdy or underground building.
  • If there is no building: Take cover behind anything that might offer protection, or lie flat on the ground and cover your head.
  • If indoors: Move to a windowless room or stay away from any windows. 

For more information, please read the Civil Protection Portal Site and Q&A by the Cabinet Secretariat. 

If a J-Alert is issued, the OIST Bosai Center will inform you on campus, and the university will provide information. As mentioned above, missiles may take less than 10 minutes to reach Japan after being launched. The fact that a J-Alert is issued does not immediately mean that the university will be closed.
