There are two kinds of frequencies in use; 50 Hertz in eastern Japan and 60 Hertz in western Japan (including Nagoya, Kyoto and Osaka).
A convertible type of electrical appliance such as a hair dryer, travel iron and shaver will therefore be handy; otherwise a step-down transformer is required to convert the voltage.
There are no columnar-shaped plugs or 3-pin plugs used in Japan but 2-flat-pin plugs are used instead. It is therefore advised to purchase a plug adapter beforehand.
