What voltage and frequency in Japan?
In Japan the standard voltage is 100 V and the frequency is 50 / 60 Hz. You can use your electric appliances in Japan, if the standard voltage in your country is in between 110 - 127 V (as is in the US, Canada and most South American countries). Manufacturers take small deviations (plus or minus 5%) into account.
If the standard voltage in your country is in the range of 220 - 240 V (as is in the UK, Europe, Asia, Africa and Australia), you need a voltage converter in Japan. 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 converter. You can also consider a combined power plug adapter/voltage converter.
If the frequency in Japan (50 / 60 Hz) differs from the one in your country, it is not advised to use your appliances. But if there is no voltage difference, you could (at your own risk) try to use the appliance for a short time. Be especially careful with moving, rotating and time related appliances like clocks, shavers or 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.
