The electricity supplied to general households is normally 100 V (partially 200 V) in voltage and either 50 Hz or 60 Hz in frequency.
Hokuriku Electric Power Company supplies electricity in 60 Hz throughout its service area.
Some electric appliances can be used exclusively on 50 Hz or 60 Hz frequency. Others may require you to switch their frequency.
Thus, please note that the use of the wrong frequency may cause the electric appliance to malfunction.
