Preparing for your trip to Japan involves more than just packing your bags. Understanding Japan’s unique electrical system is important to ensure your devices stay charged and ready for action. In this very short guide, we’ll explore the different plugs, voltage, and frequencies you’ll encounter in Japan, and the appropriate travel adapters you may need, making your stay as convenient as possible.
Japanese Power Plug Types
Japan primarily uses two types of power plugs: Type A and Type B.
- Type A: These plugs have two flat pins and are commonly found in Japan.
- Type B: Type B plugs also have two flat pins, but they come with an additional grounding pin. Type B is way less common these days, and you may never see one.
Voltage and Frequencies
In Japan, the voltage used is a consistent 100 volts, A.C. However, there are two different frequencies in use:
- 50 Hertz: Found in eastern Japan, cities like Tokyo, Yokohama, Sapporo
- 60 Hertz: Used in western Japan, including cities like Nagoya, Kyoto, and Osaka.
Certain electrical appliances, such as dual-voltage hair dryers, travel irons, and shavers, can work seamlessly throughout Japan. However, for other devices, like those that require a different voltage, you’ll need a transformer to convert the voltage.
Advice for Aussies & Kiwis
Like I’ve mentioned before, there are two types of power points in Japan and your standard Aussie plugs will not work on their own. You will need to get a travel adapter. I typically buy the basic Korjo one, and it works perfectly fine for charging iPhones, iPads, electrical shavers.
However, if you carry your laptop or a digital camera or another device that has a standard Australian 10 A power plug (3 pin) you will need to buy a 3 pin adaptor. See an the image further below of the one I use.
Do I need a voltage converter for my Aussie gadgets in Japan?
Generally, no. Japan’s electrical system operates at 100 volts, which is close enough to Australia’s 230 volts for most modern devices (mobiles, laptops, tablets…). Check your gadget’s label – if it says “100-240V”, you’re good to go without a converter.
Advice for Americans
Will my American plugs work in Japanese sockets?
Yes, they will. American and Japanese 2 pin plugs are nearly identical. Both countries use Type A and Type B plugs, so your US devices should plug in without any issues.
However, if you have a 3 pin plug you will need to get an adapter. Japanese plugs do not have the 3rd grounding pin.
Advice for the Brits
Can I use British appliances in Japan without an adaptor?
No, you can’t. British plugs are quite different from Japanese ones. You’ll need an adaptor to use UK devices in Japan. Make sure your device can handle 100 volts as well.
Finding Conversion Plugs (Adapters) and Transformers
In Japan’s large cities, you’ll find it relatively easy to acquire conversion plugs / adapters (and transformers should you need one). These essential accessories are available in electronics stores like Yodobashi Camera, or Bic Camera, and other stores that cater to international tourists. I personally shop at Bic Camera when I need a three pin adaptor so I can plug in and charge my laptop and camera.
Depending on where you live, you could also buy things in advance before you leave for Japan. Amazon, Temu and eBay have a range of adapters and transformers.
Charging on the Go
If you’re constantly on the move and need to charge your devices, there are convenient options available. Shinkansen trains feature outlets, making it hassle-free to keep your gadgets powered up during your journey. Some fast food chains and family restaurants offer accessible outlets, allowing you to recharge while you dine. A small number of accommodation providers will have usb-c charging facilities, however the large majority will not, so you should always carry an appropriate travel adapter with you.
