According to this chart, Japan uses USA-style sockets, so no adapter is needed. The voltage in Japan is 100 Volt, which is different from North America (120V), Central Europe (220V) and most other regions of the world. As Kathie says your iPhone/pad charger is an adapter and will fit into the Japanese plug.
Batteries take longer to charge. But your American TV, stereo, PC, etc will all work perfectly fine without a converter. You probably won't be able to use your cell phone in Japan unless it is a 3G phone. The standard ipod charger operates with from 100-240 v and doesn't need a converter.
If you plug an 110V appliance in 220V outlet (same as 120v to 230v, 240v) you can only hope that some protection device disconnects the power to the appliance. If you plug a 220V device into 110V outlet, it will normally last a little longer before it dies.
Japanese sockets are (mostly) physically compatible with American plugs, and although the nominal line voltage is lower in Japan (100V), the vast majority of modern electronics goods intended for American line voltage (110V) work just fine in Japan.
If you're using either a dual voltage hair dryer or your hair dryer can handle 100 volts and you have the appropriate power adapter then you'll be able to use the hair dryer in Japan.
This originates from the first purchases of generators from AEG for Tokyo in 1895 and from General Electric for Osaka in 1896. This frequency difference partitions Japan's national grid, so that power can only be moved between the two parts of the grid using frequency converters, or HVDC transmission lines.
Japanese light bulbs were rated for 100V. makers picked that voltage because it did extend the life of lightbulbs more than 110V which at the time was the most voltage that could be used until 220v lamps were developed. Then in 1914 it was settled on for the national voltage and has been that way since.
What to Pack for Japan
- Smartphone (Japan Travel SIM Card) This goes without saying, but if you use a smartphone back home, then definitely bring it with you.
- Comfy Shoes that are easy to take off.
- Power Converter or Adapter (JIS C 8303 / NEMA 1-15)
- Medication.
- Small Luggage.
- Hand Towels.
- Smart-Casual Clothes.
- Shampoo.
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). You can also consider a combined power plug adapter/voltage converter.
Voltage in Japan is 100 Volt.
Appliances brought from Europe, Australia and other Asian countries where voltage is 220 to 240V are not able to use except for lamps. Some items can be used with step-up transformer from 100V to 240V.In Japan, the voltage for electric mains is 100 V. While this number is pretty unique in the world, many countries in North America, Central America have voltages which are 110V or 120V. Using a device designed for 110V or 120V in Japan leads to a slight undervoltage, which means it will most probably still work.
A small voltage range with a dash such as 100-120V also indicates single voltage hair straighteners which can accomodate small voltage fluctuations. If the 100 volts used in a Japanese power outlet falls within the range shown on your hair straighteners then you should be able to use it in Japan.
These days, thanks to the advancements in technology, most modern mobile phone models from other countries are compatible, so there is a very high likelihood that your iPhone or Android phone will work in Japan without any hassle. Select the country where you are going, in this case — Japan.
Pashmina or wool knit, heattech clothing, long pants, wool coat, down jacket (we recommend wearing a thin down jacket under the coat). Accessories & shoes: boots, sneakers, muffler, hat, gloves, warm tights, warm socks, ear warmers, mask, snow boots.
You can't use 220v appliance in Japan. You will have to buy electronics meant for the 110v system. Some of the travel appliances do just that.
Selecting the correct converter or transformer
However, you may need a plug adapter to plug it in to the outlets abroad. Now, if the voltage rating states 110V or 120V it means that your product is only single volt and it will require a step down converter/transformer for use in 220V countries abroad.Yes, you can wear shorts in Tokyo in the summertime. Most summer attire is permitted on the city streets. Just keep in mind that among businesspeople dressed professionally, you might stand out. Are there certain areas where shorts aren't permitted, such as temples?

Please note that you will likely need a plug adapter (not the same as a voltage converter) to charge your laptop in Japan. Japan delivers 100V electricity with a non-grounded U.S. style plug. More information here. Your laptop's AC adapter will probably accept 100V electricity but you should read the label to confirm.
Check that your hair straighteners can work in Japan:
If your hair straighteners can run on 100 volts or can support dual voltage (how you can check) then you will only need to bring a suitable power adapter listed on this page if the plug on your hair straighteners will not fit.The size of a voltage converter is defined by the wattage. Therefore, the size you'll need depends on which devices you'll be powering and the number of watts they use. We would recommend using a voltage converter / transformer which has a Wattage that is 2 to 3 times higher than your appliance.
In Japan the power plugs and sockets are of type A and B. Check out the following pictures. When living in the United Kingdom you need a power plug adapter for sockets type A and B. Your appliances with plug G don't fit socket A or B.
If the 110V appliance is connected to a 220V power supply, the power may quadruple at the moment the appliance switched on, and the appliance will quickly operate in an overvoltage condition. It may be accompanied by smoke and flash, or the fuse will melt and the protection part will be damaged.
Meaning, higher current can be more dangerous than higher voltage; however, since voltage and amperage are directly proportional, 110v wiring is usually considered safer to work with because it uses fewer volts and as such can only carry half as much current as 220v wiring.
A 110V outlet (and plug) has only one hot terminal, and the hot wire is always black. Another key difference between 110 and 220 circuits is the wire size. Because 220-volt circuits carry higher current, they require 10 gauge or larger wire, whereas the normal maximum wire size in a 110-volt circuit is 12 gauge.
110V is typically the amount of current the wire can handle before it becomes unsafe, and the amount of voltage supplied to the outlet. 220V is, very simply put, 2 wires that combined produce twice the amount of voltage to the outlet.
For starters, 220 volts is not “a power”, but lets ignore that as the question is clear enough. Secondly, if you get electrocuted you're probably either already dead, or going to die from your injuries. What you want to know is whether 220V is enough to deliver a fatal electric shock. Yes, it is.
A 220 volt AC power line supplies current and the resulting power is according to the formula P = current x volts. So if you connect a motor that uses 10 amps you are consuming 220 x 10 = 2200 watts. The practical answer is that it depends on the size of the power lines and the power source.
Power = V*I so 2x the voltage * 2x the current means 4x the power that your body absorbs. It would seem to reason that 220v would be more dangerous than 110v, but neither is really all that dangerous if handled properly. 110/120V-60Hz wasn't chosen in the US for personal electrocution safety reasons.
Once AC was widely accepted as being superior to DC for power distribution, 110V became the standard for AC distribution presumably because it used the "safer" Voltage level of the DC system. After metal filament lamps became feasible, 220V became common in Europe because of the lower distribution costs.
