Do You Need a Voltage Converter?
Voltage converters are only required when the power supply is significantly different. In Hiroshima, it’s pretty much the same as in the U.S., so no need to bring one.
Before traveling, always double-check the input voltage label on your device. If it states “100-240V, 50/60 Hz”, your device is designed to handle different power systems and won’t need a converter. This includes most phones, tablets, laptops, cameras, and rechargeable personal care items.
