If you're planning a trip to Japan, it's important to understand the types of electrical outlets and plugs used in the country to avoid any inconveniences. Japan primarily uses two types of electrical plugs, known as Type A and Type B. These plug types are also used in North America, Central America, and some other countries. However, Japan operates on a lower voltage of 100V, which is different from the voltage in other parts of the world, such as North America (120V) and Europe (230V). This variation in voltage and frequency can impact the functionality and safety of your electrical devices, so it's crucial to be aware of these differences and plan accordingly.
| Characteristics | Values |
|---|---|
| Voltage | 100 volts |
| Frequency | 50 Hz in eastern Japan (including Tokyo, Yokohama, Tohoku, and Hokkaido) |
| 60 Hz in western Japan (including Osaka, Kyoto, Nagoya, Hiroshima) | |
| Plug Types | Type A (two flat parallel pins) |
| Type B (two flat parallel pins and a grounding pin) | |
| Adapter/Converter | Required if the device can handle 100 volts but has a different plug shape |
| A voltage converter/transformer is required if the device is not compatible with 100 volts and is designed for a higher voltage |

What You'll Learn
Japan's electricity supply is 100V
Japan's electricity supply is 100 volts, which is lower than the voltage in many other countries. For example, the voltage in the US is 120V, while most of Europe operates at around 230V. This means that if you are travelling to Japan from a different country, you will likely need a conversion plug or a power adapter to use your electronic devices.
The frequency of electricity in Japan also varies by region. Eastern Japan, including cities such as Tokyo, Yokohama, and Hokkaido, operates at 50 Hz, while Western Japan, including Kyoto, Osaka, and Hiroshima, uses 60 Hz. Many electrical appliances in Japan are designed with this frequency difference in mind, offering two models or being adaptable to both frequencies. However, some items, such as clocks or timing devices, may be affected by the frequency difference.
When it comes to plug types, Japan primarily uses Type A and Type B plugs. Type A plugs, which are the most common, have two flat parallel pins and are similar to the standard US two-prong plug. Type B plugs, less commonly used, are a grounded version of Type A, with an additional round pin for grounding. These are typically found in newer buildings and facilities.
If you are travelling to Japan with electrical devices, it is important to check the voltage and plug type compatibility. Many modern devices, such as smartphones, laptops, and cameras, are dual voltage (e.g. 100-240V) and will not require a voltage converter. However, appliances like hair dryers, curling irons, or electric kettles may not support Japan's lower voltage. In such cases, a voltage converter or transformer may be necessary to step down the voltage to 100V.

Type A plugs are most common
If you are planning a trip to Japan, it is important to understand the types of electrical outlets and plugs used in the country to avoid any inconveniences. Japan uses two types of electrical plugs, Type A and Type B, which are also used in North America and some other countries.
Type A plugs are the most common in Japan. They are two-pronged, flat plugs with two straight, parallel pins. This type of plug is similar to the standard two-prong plug used in the United States. Type A plugs are non-polarised and ungrounded. They are often used in older buildings and facilities in Japan. If you are from the United States or Canada, your devices likely use Type A plugs, so you won't need an adapter in Japan.
However, if your devices have three-pronged plugs, you may need to bring a Type B to Type A adapter for convenience. Type B plugs are less commonly used in Japan and include a grounding pin. They are more commonly found in newer buildings and facilities.
It is important to note that Japan operates on a lower voltage of 100V compared to other countries, so you may need to use a voltage converter or transformer for some of your electrical devices. Additionally, the frequency of electricity in Japan varies by region, with 50Hz in Eastern Japan (including Tokyo) and 60Hz in Western Japan (including Osaka and Kyoto).
To summarise, Type A plugs are the most common in Japan, and if you are travelling from a country with different plug types, it is recommended to bring a universal travel adapter to ensure your devices can be charged safely and conveniently during your stay in Japan.

Type B plugs are less common
Japan uses two main types of electrical plugs: Type A and Type B. Type A plugs are the most common and feature two flat parallel prongs. Type B plugs are less common and include a grounding pin in addition to the two flat parallel pins.
Type B plugs are less prevalent in Japan because Type A sockets, which are not grounded, are more widely available. Type B sockets, which include a grounding feature, can be found in newer buildings and facilities. However, even in these locations, Type A sockets are often still present. As a result, most travellers find that Type A plugs are sufficient for their needs during their stay in Japan.
The need for a specific plug type in Japan depends on the devices one intends to use. Type B plugs are typically required for devices that utilise three-pronged plugs. If an individual's devices have three-pronged plugs, they may need to bring a Type B to Type A adapter to ensure compatibility with Japanese sockets.
It is important to note that Japan's voltage is 100V, which is lower than many other countries. This difference in voltage may require the use of a voltage converter or transformer for certain devices to function properly. It is recommended to check the voltage requirements of devices before travelling to Japan to ensure compatibility.
In summary, Type B plugs are less common in Japan due to the prevalence of Type A sockets and the fact that many travellers' devices may only require the more common Type A plug. However, for those with devices requiring three-pronged plugs, Type B adapters or sockets may be necessary.

You may need a voltage converter
Japan's power sockets are of type A and type B, with type A being the most common. Type A plugs have two flat parallel pins, while type B plugs include a grounding pin. The standard voltage in Japan is 100V, which is lower than the voltage in many other countries. For example, the United States and Canada have a voltage of 120V, while most of Europe, Australia, and New Zealand have voltages around 230V-240V.
Due to the difference in voltage, you may need a voltage converter when travelling to Japan. Most modern electronic chargers, such as those for smartphones, laptops, and cameras, are dual voltage (e.g. 100V-240V) and can be used in multiple countries without a converter. However, high-wattage devices such as hair dryers, curling irons, or electric kettles may not support Japan's lower voltage.
To determine if you need a voltage converter, check the voltage range on your devices. If your device has an input of 100-240V, it can be used in Japan without a converter. If your device is not dual voltage, you will need to use a voltage converter or transformer to allow the appliance to work safely and properly.
It is important to note that voltage converters can sometimes be hard to find, and using your electric devices in Japan without a converter may cause them to not function optimally. Low voltage can lead to overheating and reduced lifespan, and the wrong frequency can cause unexpected behaviour. If you plan to buy electronics in Japan, ensure they are compatible with your home country's voltage if you intend to use them there.
In addition to a voltage converter, you may also need a power plug adapter for Japan. If your devices have three-pronged plugs (Type B), you will need a Type B to Type A adapter. USB-C chargers are compatible with Japanese outlets as long as you have a USB port or a plug adapter.
