If you have a contract with Tokyo Gas for electricity, but do not have an ampere breaker:

The smart meter system regulates the contract ampere. Once a period of time (approximately 10 seconds) has elapsed after the lights turn off, they will come back on automatically. If the electricity cuts off multiple times consecutively, and does not turn back on automatically, please contact TEPCO Power Grid Inc.

If the above do not apply or you do not know what to do:

Please contact TEPCO Power Grid Inc.

A portion of the lights in my house went out!

Please contact TEPCO Power Grid Inc.

Using Gas Appliances During a Power Outage

Be sure there is proper ventilation during a power outage

  • Power outages may cause ventilation fans to stop working or make it difficult to see, leading to a wrong operation of gas appliances at night, so please be extra careful during use.
  • If you need to use a gas appliance, ensure that it has proper ventilation.
  • Pay particularly close attention to ventilation when using small gas water heaters, gas heaters and industrial appliances.
  • Bear in mind that gas appliances that require a 100V power source (outlet connection) are unusable during an outage.
