・ On the app screen, you can check the latest disaster information for each current location and registered area, as well as evacuation areas for each type of disaster.

・ "Heavy rain forecast" is a push notification before heavy rain. It is also recommended for everyday use such as measures against guerrilla rainstorms.

-The "Disaster Map" allows users to share the disaster situation between users and see what kind of disaster is approaching and how far.

・ The "Disaster Prevention Handbook" can be used not only for disasters such as registration of evacuation areas, hazard maps, and confirmation of disaster prevention supplies, but also for everyday preparations.

[Application example]

・ Preparing for earthquakes and tsunamis at travel destinations

If you enable the current location link, you can receive Earthquake Early Warnings at your travel destination without changing the settings.

You will also be notified when a tsunami warning / warning is announced, so you can take evacuation action as soon as possible.

* Earthquake early warning may not be in time near the epicenter.
