Do You Need a Voltage Converter?
You’ll only need a voltage converter if your device’s voltage doesn’t match the country you’re visiting. In Japan, you won’t need one since the voltage is about the same as in the U.S.
Always double-check the label on your device before using it abroad. If it shows “100-240V, 50/60 Hz”, your device is dual voltage and works on both 120V and 220-240V power sources without a converter. This is common for laptops, tablets, smartphones, cameras, and electric toothbrushes.
