If an earthquake happens

Japan has one of the highest rates of earthquakes in the world. Chance of injury during an earthquake can be reduced with proper preparation. Important steps should be taken in the event of an earthquake.

During an Earthquake

During an Earthquake

The most important thing to do is remain calm during an earthquake. Turn off all electrical and gas appliances. Especially turn off heating appliances such as irons and dryers. Do not turn on gas, appliances, or light a fire during an earthquake. Large earthquakes can damage gas pipes leading to a gas leak.
Your gas meter should be equipped with a microcomputer meter that will turn off gas flow in the event of an earthquake larger than a seismic intensity of 5 (5震度).

In large enough earthquakes, gas service may stop for an entire region. Click here to see if you are in the affected area.The page is only available in Japanese currently.

Right after an earthquake, close the gas taps and gas meter valve. This is a preventative action to decrease the danger of fire.

After an Earthquake

Right after an earthquake, close the appliances valves and the gas taps(main valve) to reduce the risk of fire.

If you notice a gas leak, open doors or windows immediately. Evacuate the residence and call Osaka Gas as soon as you are safe.
Do not turn on any electrical or fire appliances.

Before using gas, please make sure that there is no gas odor, and then open gas taps.

If gas does not flow, gas flow could be restored by resetting the gas meter. Please follow the steps to reset the meter shown in this page.
In the case of a large earthquake, resetting the gas meter might not restore the gas flow due to the area-wide gas supply outage or gas pipeline damage.
