Buy a power plug (travel) adapter

We don't sell power plug adapters. We refer you to Amazon, where you will find a great selection of travel adapters. Because you may also need a voltage converter, you should consider a combined power plug adapter/voltage converter (see below).

Voltage converter needed in Japan?

In Japan the standard voltage is 100 V and the frequency is 50 / 60 Hz.

  • The voltage in Japan (100 V) is less than in the United States of America (120 V). You need a voltage converter.

Some say you can carefully try to use your appliances in Japan without a converter. Most likely they won't be damaged, but may not function optimally. If you don't want to take any chances, use a voltage converter in Japan when living in the United States of America. You can find voltage converters at Amazon.

Also the frequency in Japan (50 / 60 Hz) differs from the frequency in the United States of America (60 Hz). You should use a voltage converter which also changes the frequency, but these are hard to find. If your converter cannot change the frequency, be warned! Be especially careful with moving, rotating and time related appliances like clocks, shavers and electric fan heaters.

To be sure, check the label on the appliance. Some appliances never need a converter. If the label states 'INPUT: 100-240V, 50/60 Hz' the appliance can be used in all countries in the world. This is common for chargers of tablets/laptops, photo cameras, cell phones, toothbrushes, etc.
