What is the voltage and frequency in Japan?

The standard voltage and frequency used in Japan are 100 V and 50/60 Hz.

Travelers from countries with a standard voltage between 110 V and 127 V, such as Canada, the US, and countries in South America, can use electric appliances in Japan without a voltage converter.

This is because manufacturers consider slight deviations in voltage of up to plus or minus 5%.

However, suppose you are from a country with a standard voltage between 220 V and 240 V, such as Australia, the UK, Europe, Africa, and most parts of Asia. In that case, you can use electric appliances in Japan only with a voltage converter.

In rare instances where the standard frequency of Japan is different from that of a traveler’s country, it is best that electric appliances are not used in Japan.

If no voltage difference exists, electric appliances can be used at the owner’s risk but only for a limited period.

When doing so, caution should be exercised when using rotating, moving, or time-related appliances such as electric fan heaters, shavers, or clocks, as they will not function optimally.

Certain appliances are free from voltage issues as they can be used with all voltages and frequencies.

On the label of such appliances, an inscription such as “INPUT: 100 V – 240 V; 50/60 Hz” is written.

These devices include chargers of phone cameras, cell phones, tablets, laptops, and electric toothbrushes.
