【Japan Travel】Japanese Sockets & Japanese Voltage Tips!

Japanese socket types

The main type of socket used in Japan is TYPE-A, which is a two-pin flat socket, the same type as the socket in Taiwan. If you have an appliance with a three-pin plug, remember to bring an adapter as Japanese sockets only support two-pin plugs.

In addition to Japan, TYPE-A sockets are also widely used in Taiwan, North America, Mexico and other places, so if you are traveling to Japan from these areas, the socket types will be relatively similar and there is no need to prepare an additional converter.

Japan's voltage

Japan's standard voltage is 100V, while Taiwan's is 110V. The difference between the two is small. Transformers are generally not required when using Taiwanese electrical appliances. If the input voltage range of your electrical appliance is marked as "100V-240V", such as a laptop or mobile phone charger, it can be used directly in Japan.

However, if the electrical appliance is only suitable for 220V (such as the voltage in Hong Kong), then you must bring a transformer to adjust the voltage to prevent the electrical appliance from not working or being damaged.

Can Hong Kong electrical appliances be used in Japan?

Since the voltage in Hong Kong is 220V and Japan is only 100V, there is a big gap between the two. Therefore, if the appliance you are carrying only supports 220V (such as some hair dryers or electric kettles), you must bring a transformer to adjust the voltage before it can be used in Japan. However, appliances with a wide voltage range (such as 100V-240V), such as mobile phone chargers or laptops, can be used directly without a transformer.

Can Taiwanese electrical appliances be used in Japan?

Taiwan's voltage is 110V, which is not much different from Japan's 100V, so most Taiwanese electrical appliances can be used directly in Japan without a transformer. But if the electrical appliances you carry are sensitive to voltage, you may consider using a transformer to ensure the safety of your equipment.

If I buy electrical appliances from Japan and use them in Taiwan, will it affect the lifespan?

Since the voltage in Japan is 100V and in Taiwan is 110V, this 10V difference usually does not have a significant impact on most electrical appliances, especially for short-term use. However, in the long run, this gap may cause some electrical appliances to withstand higher voltages, which may cause the equipment to overheat and shorten its life. Therefore, if you are purchasing a higher-priced or voltage-sensitive appliance, it is recommended to use a transformer or check whether the appliance is marked to support 110V voltage.

Can I buy electrical appliances from Japan and use them in Hong Kong?

When using Japanese electrical appliances in Hong Kong, you need to pay special attention to voltage issues. The voltage in Japan is 100V, while in Hong Kong it is 220V. If the electrical appliance you buy from Japan only supports 100V, you must bring a transformer to adjust the voltage to 220V, otherwise the electrical appliance may be damaged. On the other hand, if the electrical appliance supports a wide voltage range of 100V-240V, no transformer is required and it can be used directly in Hong Kong.

Buy transformers and adapters in Japan

Don’t worry if you forget to bring an adapter or transformer. You can buy it at large electronics stores such as Bic Camera and Yodobashi in Japan. These stores often provide multi-language services, including Chinese and English, and tax-free services. Basic adapters are also available at airport convenience stores, but they are usually more expensive, so it’s best to prepare in advance.

Japan travel essentials list

When traveling to Japan, in addition to understanding the local voltage and sockets, you also need to prepare the following essential items:

• ID card, passport and other documents

• Wallet (local currency, credit card, ATM card)

• Mobile phones and chargers

• Power bank

• Adapter (if the appliance has a three-pin plug)

• International driver's license (if applicable)

• Local calling card or Wi-Fi egg

• Small size transformer (if needed)

• Toothbrushes, toothpaste and other personal care products

• Skin care products such as hand cream and moisturizing spray

I hope this information can help you have a smoother trip to Japan!
