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 Kingdom (230 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. You can find voltage converters at Amazon.
Also the frequency in Japan (50 / 60 Hz) differs from the frequency in the United Kingdom (50 Hz). You should use a voltage converter which also changes the frequency, but these are hard to find. If your converter can't 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.
