Service details

Leave the installation to us

Please leave the connection work and detailed settings of the dedicated terminal to J:COM.

high accuracy

Based on information from the Japan Meteorological Business Support Center, a dedicated terminal installed in the customer's home calculates and notifies the predicted seismic intensity and grace period.

Notification seismic intensity can be set

At the time of contract, you can choose the predicted seismic intensity to be notified on the dedicated terminal from seismic intensity 3 or 4.

Equipped with FM radio function ^*4

The dedicated terminal is equipped with an FM radio function. In the event of a disaster, it can be removed and carried as an FM radio.

Support status for "List of measures to be taken by terminal users"

Earthquake early warning

We will inform you of the earthquake early warning with flash and voice.

*The items provided may differ from the photos.

The grace time will be announced in units of 10 seconds, 10/20/30 seconds.
If the grace period is short, the announcement will be shortened, such as "(Sign sound) An earthquake with a seismic intensity of about ○ is coming soon."
If the predicted seismic intensity is 3 or 4 or higher, you will be notified by flash and voice. (You can choose at the time of contract)
Predicted seismic intensity and grace time are calculated for each area indicated by your postal code.
Deep-focused earthquakes (earthquakes with very deep epicenters) may have large prediction errors.

Mechanism of earthquake early warning

Seismic waves consist of P waves (primary tremors) and S waves (principal tremors), and the speed of propagation differs between P waves and S waves. Estimate the location of the epicenter and the magnitude of the earthquake from the P-waves that arrive first. You can prepare for an upcoming earthquake before the strong shaking S-waves arrive.

[Regarding the limits of the Earthquake Early Warning system]
・Earthquake early warnings may not arrive in time if the epicenter is near. * There may be an error of about ±1 in the seismic intensity to be notified.

Disaster prevention administrative radio

It is safe because you can hear the disaster prevention administrative radio in the room.
We will inform you of local life / crime prevention information and disaster prevention information in the event of a large-scale disaster.

* It will be provided sequentially from the area where the contract related to the disaster prevention administrative radio has been concluded with the local government.
*Broadcast contents and expressions differ depending on the local government in which you live.

TV activation in the event of a disaster

Just connect the dedicated terminal to the TV. In the event of a disaster ^*, the TV will automatically turn on and notify you of disaster information.
*When local governments and the Meteorological Agency issue some evacuation information and weather warnings.
