In Japan, 2-flat-pin plugs are used instead of columnar-shaped plugs or 3-pin plugs. The voltage used throughout Japan is uniformly 100 volts, A.C. There are two kinds of frequencies in use; 60 Hertz in western Japan and 50 Hertz in eastern Japan (including Hokkaido). A convertible type of electrical appliances such as a travel iron, hair dryer, and shaver will therefore be handy. Otherwise, a step-down transformer is required to convert the voltage. 2-PIN 2-PIN + EARTH
