Voltage is fundamental when travelling abroad. Mobile devices, including smartphones and other daily necessities, will need to be charged. Also, there is quite a consistent number of people from overseas who end up buying electronic devices in Japan. Don’t do that, as you won’t be able to use them abroad. Types and voltages of power plugs vary from country to country. They can differ even within the same country or region. Hence why we would like to introduce Japanese power supply / voltage.
The power plug used in Japan is generally the “A type”. It is also used in the United States, Canada, South America, Thailand, Vietnam, and the Philippines. A conversion plug to be able to plug in different types of electrical appliances will be required. However, it should be stressed that the voltage in Japan is 100V, which is a lower voltage than in other countries. Recent electrical appliances, especially smartphones and personal computers, are often compatible with Japanese plugs. So you can stay reassured. Also note that East Japan and West Japan have a different power supply. East Japan has a power supply of 50Hz, and West Japan of 60Hz. For domestic appliances, there is no problem, but please check the frequency for the devices you bring.
If you forget to bring a conversion plug or transformer, you shouldn’t worry! Because there is a home appliance mass retailer in Japan. If you show them the electrical devices you want to use, you will be recommended the best conversion device for you. Moreover, home appliance mass retailers are very convenient for purchasing Japanese electronics in general. If it is a large-scale device retail store, there will be a whole dedicated sales area for products that can be used overseas as well. The staff will be able to guide you. At the time of purchase, make sure to check the type and voltage of the power plug. For electrical devices that require a transformer, be sure also to check the transformer capacity range. Should you have any doubts, please ask the staff
