Public Utility Prices in Japan (Electricity, Gas, Water)

Poste date: Monday, February 19, 2018

Public utilities such as electricity, gas, and water supply, are basic necessities for everyday life. Here we explain easily the rate structure, payment methods, and a rough average cost per month by the number of household, to assist in gauging your budget for life in Japan.

Gas and electricity meters are checked once a month, and a "notice of consumption" showing how much has been used will be left in your mailbox. The notice indicates the amount to be billed and also serves as a receipt if your bill is paid via the automatic bank withdrawal. This is not a bill, so it cannot be used to pay for your consumption. The monthly bill will be sent to you shortly after the inspection unless you have arranged for the automatic payment of your bills. It has a bar code inscribed on it so is easily discernable. The water meter is checked once every two months, and for both water and sewage a notice of consumption will be left in your mailbox and a bill is sent every two months accordingly.

Utility bills can be arranged for the automatic payment of bills from a Japanese bank or post office account. You can also pay in cash at post offices, most Japanese banks, Citibank Japan, some other foreign banks, and most convenience stores, such as 7-Eleven. For further details on contracts and application for different payment methods, please contact each utility company or its local office.

Electricity and gas rates vary monthly according to current fuel costs and exchange rate fluctuations.

The billed amount will be more than the average rates in case of using a central air conditioner unit or a contract of higher voltage. A central air conditioning unit uses a separate energy source therefore resulting in two electricity bills.
