Ready to plug in your devices in Japan?
Hold on! Before you do, you need to know that Japan’s electrical system is a bit unique.
Plugging in the wrong device can damage your electronics forever.
This simple guide will explain everything you need to know about adapters and converters to keep your tech safe.
Understanding Japan’s Electricity
Voltage: 100V
Japan runs on 100 Volts, which is lower than most other countries (e.g., North America is 120V, Europe is 230V).
Most modern electronics like laptops and smartphone chargers are “dual voltage” and can handle a range from 100V to 240V.
Check the fine print on your charger to be sure.
Plug Type: Type A
Japan uses the Type A plug, which has two flat, parallel pins.
This is the same type used in North America, but without the third grounding pin.
Adapter vs. Converter: What You Really Need
These two words are often confused, but they do very different things.
- An Adapter simply changes the shape of your plug to fit the wall socket. It does NOT change the voltage.
- A Converter (or Transformer) actually changes the voltage of the electricity. You only need this for high-power, single-voltage devices like some hair dryers or electric shavers.
For most travelers, you will only need an adapter.
Our Recommendation: The Only Adapter You’ll Need
So, what kind of adapter should you buy?
For most travelers, a universal travel adapter is the best and most cost-effective choice.
It covers over 150 countries, so you can use it not just for Japan but for all your future travels.
A reliable one with multiple USB ports is great for charging all your devices at once.
