Earthquake disaster prevention & stable supply

Tokyo Gas engages in research and development that supports LNG terminals, pipelines and other gas supply infrastructure with the goals of providing stable city gas services to its customers, delivering reassurance and security to its customers, and ensuring customers can use city gas with peace of mind.
In addition, we also develop disaster prevention systems from major earthquakes and other disasters with the aim of realizing stable gas supply that is resilient to such disasters.
