Electrical appliances in Japan: voltage, adapter, and tips before you leave

When packing for a trip to Japan, one question often comes up: can I use my electrical devices there?

Between voltage differences, plug types and airplane rules, the information is sometimes contradictory… Don't panic: Ayumi Voyage explains everything!

Ayumi's key points:

• Always check the compatibility of your devices ( INPUT 100V–240V ).

• Bring a Type A (or universal) adapter with USB ports

• Keep your power banks in your carry-on bag

• If you're tempted by a high-tech purchase while you're there, make sure it works well in your own country!

Voltage and electrical outlets in Japan

One of the main fears for travelers is damaging an appliance by plugging it in in Japan. The good news is that most modern electronic devices (phones, computers, cameras, razors, etc.) now operate on a universal voltage of 100 to 240 volts and a frequency of 50 to 60 hertz.

In short: your devices will work in Japan, provided you use a simple plug adapter.

Which adapter do I need for Japan?

Japanese plugs have two flat prongs, while French plugs have two round prongs. Therefore, a compatible adapter is required.

💡 Ayumi Travel Tip: Opt for a universal adapter with USB ports. You'll be able to charge several phones or tablets at the same time!

And if you forgot it at home? No worries: you can easily find one at the airport , or in large electronics stores like Bic Camera or Yodobashi Camera .

A sometimes reduced power

Japan operates on a voltage of 100V, lower than that of France (230V) or the the USA (120-240).

Some devices used in Japan may therefore seem less powerful: a slightly weak hair dryer or a phone that takes longer to charge.

Before leaving, always check that your devices are marked:

INPUT 100V–240V – 50/60Hz

Electrical appliances and air transport

Whether it's a computer, a tablet, or even a drone, most electronic devices can travel without any problems, whether in the hold or in the cabin. So you can easily play Paw Patrol for your child on the tablet during the flight!

On the other hand, heat-producing appliances (hair dryers, straighteners, etc.) must be placed in the hold.

External batteries: beware of the rules!

External batteries are now subject to strict regulations. Most airlines apply the following rules:

• External batteries must be carried in the cabin; they are prohibited in the hold.

• It is forbidden to use them during the flight

• Their capacity is limited to 100 Wh or 27,000 mAh: absolutely check, otherwise your battery will end up in the trash!

In all cases, remember to check the specific rules on your airline's website before departure.

Buying electrical equipment in Japan

Photography, video game, and electronics enthusiasts: welcome to paradise! Stores like Yodobashi Camera or Bic Camera, as well as secondhand shops, are veritable treasure troves for enthusiasts. But before you buy a device (console, camera, etc.), check that the charger is compatible with your country's voltage:

• 230V for Europe

• 120V for Canada or the United States

If so, a simple adapter will be sufficient to use it upon your return.

However, for household appliances (like a takoyaki machine to impress your friends or a state-of-the-art Japanese hair dryer), you'll need a transformer. This device, often heavy and expensive, is necessary to convert the voltage.
