Power Plug Guide Will your devices work abroad?

What plug is used in Japan?

In Japan, the standard power plug is Type A and Type B. The country runs on 100 volts at 50/60 Hz. That means wall sockets in Japan can be one of 2 different shapes — Type A, Type B, and your plug needs to physically match the socket to fit.

Travel adapters for Japan

Most modern phones, laptops, cameras, and tablets are rated for 100–240 V, so you only need a simple plug-shape adapter when the voltage matches what your charger supports. Because Japan runs on the lower 100 V range, travelers from 220–240 V regions (Europe, the UK, Australia, most of Asia) usually do not need a voltage converter for low-power electronics. Hair dryers, curling irons, and kettles brought from a 220 V country, however, will run weakly or not at all here. For a Type A/Type B socket, a universal travel adapter or a region-specific adapter is enough for chargers that handle dual voltage.

Frequently asked

What plug does Japan use?

Japan uses Type A and Type B plugs and runs at 100 volts, 50/60 Hz.

Do I need a travel adapter for Japan?

Yes, if your home country does not use Type A and Type B. Most modern phone and laptop chargers handle 100–240 V, so a simple plug-shape adapter is enough.

What voltage is used in Japan?

Mains voltage in Japan is 100 V at 50/60 Hz.

Can I use my phone or laptop charger in Japan?

Almost always yes. Modern phone, laptop, tablet and camera chargers are dual-voltage (rated 100–240 V), so they handle Japan's 100 V automatically. You only need a plug-shape adapter, not a voltage converter. Check the small print on the charger to confirm.
