Japan uses two main types of electric plugs: Type A and occasionally Type B. Type A plugs are the most common and feature two flat parallel pins, whereas Type B plugs include a grounding pin. The standard voltage in Japan is 100V, which is lower than the standard voltage in many countries. As a result, some devices from countries with higher standard voltages may not work efficiently or may require a voltage transformer or power converter.

What You'll Learn
Japan's electric plugs are Type A and Type B
Japan uses two main types of electric plugs and sockets: Type A and occasionally Type B. Type A plugs have two flat parallel pins, while Type B plugs have two flat parallel pins and a grounding pin. Type A plugs are the most common in Japan and are also used in North America, Central America, and some other countries. Type B outlets do exist in Japan, but they are not as widely used as Type A.
If you are travelling to Japan from the US or Canada, your devices likely use Type A or Type B plugs, so no adapter is necessary. However, if you have three-pronged Type B plugs, it is recommended to bring a Type B to Type A adapter for convenience. If you are from Europe, the UK, Australia, or other countries, your plugs are likely different (e.g., Type C, G, or I), and you will need a universal travel adapter that works with Type A outlets. You can purchase adapters at electronic stores like Bic Camera or convenience stores.
It is important to note that Japan's voltage is 100V, which is lower than the standard voltage in many countries. While many modern electronics like smartphones, laptops, and cameras are dual voltage (e.g., 100-240V) and will not need a voltage converter, high-wattage devices like hair dryers, curling irons, or electric kettles may not support Japan's lower voltage and will require a voltage converter or transformer. Additionally, the frequency of electricity in Japan varies by region, with 50Hz in eastern Japan (including Tokyo, Yokohama, and Hokkaido) and 60Hz in western Japan (including Kyoto, Osaka, and Hiroshima). These differences in frequency can affect timing devices and appliances with motors, so it may be necessary to use a voltage converter or transformer to prevent issues.

Type A plugs have two flat parallel pins
Japan uses two main types of plugs: Type A and occasionally Type B power outlets. Type A plugs, which are the most common in Japan, have two flat parallel pins. These plugs are also the standard in North America. If you are travelling to Japan from the US 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 is recommended to bring a Type B to Type A adapter for convenience.
It is important to note that while Type A plugs are the most common in Japan, the voltage is different from that of North America. Japan operates on a 100V supply voltage and 50/60Hz frequency. Most voltage converters and transformers are supplied with plug adapters. However, it is essential to check the voltage specifications on electronic devices and use appropriate transformers or converters when necessary, as using devices at an incorrect voltage can pose safety risks, including electrical shock, short-circuiting, and fire hazards.
If you are travelling to Japan from Europe, the UK, Australia, or other countries, your plugs are likely different (e.g., Type C, G, or I). You will need a universal travel adapter that works with Type A outlets. These adapters can be purchased at electronic stores like Bic Camera or convenience stores.

Type B plugs have two flat pins and a grounding pin
Japan uses two main types of plugs: Type A and Type B. Type A plugs, which are the most common, have two flat parallel pins. Type B plugs, on the other hand, have two flat pins and a grounding pin. While Type B outlets exist in Japan, they are not as widely used as Type A.
If you are travelling to Japan from the US or Canada, your devices will likely use Type A or Type B plugs, so no adapter is necessary. However, if your devices have three-pronged plugs (Type B), it is recommended to bring a Type B to Type A adapter for convenience, as Type A sockets are more common in Japan.
It is important to note that Japan's voltage is 100V, which is lower than the standard voltage in many countries. While many modern electronics like smartphones, laptops, and cameras are dual voltage (e.g., 100-240V) and will not need a voltage converter, high-wattage devices like hair dryers, curling irons, or electric kettles may not support Japan's lower voltage and will require a voltage converter.

These differences in frequency can affect timing devices and appliances with motors, so it is essential to check the voltage and frequency specifications of your electronic devices and use appropriate transformers or converters when necessary.

Type A plugs are the most common
The voltage in Japan is 100V, which is lower than the standard voltage in many countries. While many modern electronics like smartphones, laptops, and cameras are dual voltage (e.g. 100-240V), high-wattage devices like hair dryers, curling irons, or electric kettles may not support Japan's lower voltage and may require a voltage converter. It's worth noting that voltage converters and transformers may come with plug adapters, but you can also purchase a universal travel adapter that works with Type A outlets.
It's important to note that electrical outlets in Japan are mostly consistent with North American sockets. However, there are two types of outlets in the country: Type A and Type B. Type B plugs, which are also flat and two-pronged but include a grounding pin, are less commonly used. While you can physically fit a Type B plug into a Type A socket, the grounding pin on the Type B plug will not function because Type A sockets are not grounded.
If you're travelling with devices that require an earth connection, be sure to check your appliances before your trip to understand their requirements in Japan. Some travel adapters are not suitable for appliances that require an earth connection and should only be used with double-insulated equipment.

You may need a voltage converter for high-wattage devices
Japan operates on a 100V supply voltage, which is lower than the voltage level in many countries. For example, the voltage level in the United States is 120V. As such, you may need a voltage converter for high-wattage devices when travelling to Japan.
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. However, appliances like hair dryers, curling irons, or electric kettles may not support Japan's lower voltage. In this case, you will need a voltage converter to safely use them.
If you do not want to use a voltage converter, you can try using your electric devices in Japan without one. They will most likely not be damaged, but they may not function optimally. However, do note that a low voltage can lead to overheating and a reduced lifespan of your devices. The wrong frequency can also cause unexpected behaviour. If you decide to proceed without a converter, exercise special caution with motorized devices and those containing electronic chips, such as clocks, shavers, and medical devices.
To determine whether you need a voltage converter or transformer, look at the appliance rating plate. A dual voltage rated appliance will display, for example, 'INPUT: 100-240V' on the body of the appliance or its power supply. This means that you will only need a travel adaptor, as Japan's supply voltage falls within the range that the dual voltage appliance operates on. If the appliance is not dual voltage rated, you will need to use a voltage transformer or converter.
