What Plug Do You Need for Japan?
Planning a trip to Japan? Besides packing your essentials, understanding the types of electrical outlets and electrical plugs used in Japan is crucial for a hassle-free experience.
The voltage in Japan is 100 volts, which is lower than in many other countries. Nothing’s worse than arriving at your accommodation and realizing your electronics can’t be charged. This guide will walk you through everything you need to know about Japan’s plug type, power outlets, voltage, and whether you’ll need a power adapter.

Japan uses two main types of plugs — Type A and occasionally Type B power outlets.
- Type A plug: This is a two-pronged, flat plug often found in North America. It’s the most common type of plug in Japan.
- Type B plug: This is also a flat, two-pronged plug but includes a grounding pin. While Type B outlets exist, they are not as widely used as Type A.
For most travelers, the Type A plug will work perfectly fine in Japan.
Will You Need a Plug Adapter for Japan?

Whether or not you need a plug adapter depends on where you're coming from:
- If you’re from the U.S. or Canada: Your devices likely use Type A or Type B plugs, so no adapter is necessary. However, if your devices have three-pronged plugs (Type B), it’s worth bringing a Type B to Type A adapter for convenience.
- If you’re from Europe, the UK, Australia, or other countries: Your plugs are likely different (e.g., Type C, G, or I). You’ll need a universal travel adapter that works with Type A outlets.
Forgot your adapter? Electronic stores like Bic Camera sell adapters for foreign travelers. Convenience stores might also carry basic models.
What Voltage Does Japan Use?
Japan operates on 100 volts, which is lower than the standard voltage in many countries. The frequency of electricity varies by region:
- 50 Hz in eastern Japan, including Tokyo, Yokohama, and Hokkaido.
- 60 Hz in western Japan, including Kyoto, Osaka, and Hiroshima.
You should avoid using an electrical appliance that is rated at a voltage different from the supply — take note if you're planning to bring your electronics like a hair dryer!
Do You Need a Voltage Converter for Dual Voltage Devices?
Japan’s 100-volt system may be lower than what your devices are designed for. Here’s how to determine if you need a converter:
- Check the Voltage Range on Your Devices: Many modern electronics like smartphones, laptops, and cameras are dual voltage (e.g., 100-240V). If your device falls within this range, you won’t need a voltage converter.
- High-Wattage Devices: Appliances like hair dryers, curling irons, or electric kettles may not support Japan’s lower voltage. In this case, you’ll need a voltage converter to safely use them. For continuous use with appliances, consider using a voltage transformer instead.
- Japan-Specific Electronics: If you plan to buy electronics in Japan, ensure they’re compatible with your home country’s voltage if you intend to bring them back.
FAQs About Japan’s Electric Outlets
What type of plug is used in Japan?
Japan uses Type A plugs, which are two flat parallel prongs, and occasionally Type B plugs, which include a grounding pin. Type A is the most common.
Are Japan and the US plug the same?
Yes, the plugs in Japan (Type A and Type B) are the same as those used in the US. However, Japan operates on a lower voltage (100V) compared to the US (120V).
Can I charge my phone in Japan?
Yes! Most smartphones are dual voltage (100-240V). If your plug is Type A, you can directly charge it without an adapter.
Do Japanese outlets have a grounding pin?
Some outlets support Type B plugs with a grounding pin, but they are less common. If you use three-pronged plugs, bring a Type B to Type A adapter.
