Stable Supply and Security

Total pipeline length 1.5 times around the Earth, Number of customers Over 11 million, Serious supply disruptions 0 cases


As a gas pipeline operator, we reliably supply clean city gas to more than 11 million customers via pipelines stretching a total of approximately 60,000 km, equivalent to 1.5 times the circumference of the Earth. In fiscal 2018, there were zero serious supply disruptions across the entire 60,000 km of our pipeline network.




Time taken from detecting a major quake to remote shutdown 10 minutes

We have installed approximately 4,000 seismometers within our service area so that gas supply is automatically suspended when a major earthquake is detected. We can also remotely shut down seriously affected areas based on additional earthquake information obtained from our seismometers.


Recovery support for the Osaka earthquake 1,200 personnel

City gas operators in Japan have established a mutual support system for the quick recovery of service after a major earthquake or other disaster. The Tokyo Gas Group dispatched 1,200 personnel at the time of the 2018 Osaka earthquake, which allowed for the resumption of gas supply to all households within six days.
