In Japan, power outlets are of type A and B, similar to USA. A plug adapter is required for type A outlets. B outlets are compatible with your plugs, although they aren't always common in some areas.
Since you'll need a travel adapter for Japan when coming from USA, we suggest opting for a universal power adapter that works in many countries and will also prepare you for future trips.
Make sure to get a power adapter for outlets of type A. If you often go abroad, consider getting an all-in-one adapter (most adapters even have additional charging ports for USB-A and USB-C).Since you also need an international power (voltage) converter to keep your devices protected (more info further down), getting a combo power adapter/converter might be the best solution.
Japan uses 100 V at 50 / 60 Hz, while USA operates on 120 V at 60 Hz. This voltage and frequency difference can affect your devices if they are not designed to handle both standards, potentially causing damage or malfunction.
A voltage converter keeps your electrical devices from USA running properly by adjusting the power to the right voltage. Without it, your devices could overheat or get damaged from the wrong power supply. Since you need a travel adapter as well, a combo power (voltage) converter with adapter features might be a good choice.
Please note: If your voltage converter can't switch the frequency, it's safer not to use your electronics. Proceeding without caution could lead to issues, especially with devices that rely on precise timing or motors, like hair dryers, electric razors, kitchen appliances, and health-related equipment such as blood pressure monitors. These kinds of electronics are more vulnerable to damage or malfunction when the frequency is off. If you choose to use them anyway, be extremely cautious and always check the specifications first.
To confirm, check if your devices require a voltage converter by looking at the 'INPUT' label, typically found on the power adapter or charger. If the label shows "INPUT: 100-240V, 50/60 Hz," the device is built to handle different voltage and frequency ranges, meaning you'll only need a plug adapter for the outlets in Japan. This is typical for devices such as notebooks, smartphones, digital cameras, and also for tablets, e-readers, and some battery chargers.
No, you will need a voltage converter. USA uses 120 V, while Japan uses 100 V, and the frequency difference (USA's 60 Hz vs. Japan's 50/60 Hz) may also affect the motor in your hair dryer. Without a converter, the device could malfunction or not work properly.
Yes, most laptops and smartphones are designed to work with a voltage range of 100-240V, so they will work in Japan without a voltage converter.
No, you will need a voltage converter to use your American curling or flat iron in Japan due to the lower voltage (120 V vs. 100 V). The frequency difference (50/60 Hz in Japan) may also cause performance issues, such as uneven heating. A voltage converter is required to safely use the device.
Yes, when traveling from USA, you will need a power adapter for type A power outlets in Japan.
Yes, you will need a voltage converter for devices that are designed to work with 100 V. USA operates on 120 V, and the different frequency (50/60 Hz) may also affect some devices with motors or timers. However, modern devices like laptops and smartphones that support 100-240V won't require a converter.
