Electrical adapters in Japan
In Japan, you do not need a power plug adaptor if you are traveling from the United States. Your power plugs are compatible. If type B connectors are not available, we recommend bringing a 3 to 2 prong adaptor. Your appliances that use plugs A and B are compatible. However, checking the specifications of your device is a good idea.
Japan’s 2 frequencies
The voltage for the electric power supply in Japan is 100V. Most electrical equipment can survive a 10-20% variation in voltage, but overvoltage is typically more harmful. In Japan, using a gadget built for 110V or 120V results in a small under-voltage, but it will most likely still operate without issue.
Phone chargers in Japan
You won’t need a voltage, frequency, or plug-shape converter in Japan. While a regular US two-prong plug will work in a Japanese outlet, you must ensure that your phone charger will operate at 100V, 50/60Hz without damaging sensitive electronics.
Japanese and American outlets
Japanese outlets feature two flat prongs. The prongs are non-polarized and most devices can be plugged into them. Two prongs are seen on many American-market products and will fit into these two prong only Japanese outlets. Anything with a third prong from the US will not work in a Japanese outlet.
US hairdryers in Japan
A single voltage hair dryer may also support a modest voltage range, such as 100-120V, indicating that the hair drier can withstand modest voltage variations. Your hair drier will operate in Japan as long as the 100V used is within this range. However the dryer may not heat as efficiently.
Tokyo 50HZ or 60HZ
In total eastern Japan including Tokyo, Yokohama, and other northern areas of Japan, the frequency of electricity is 50 Hertz. Western Japan including Nagoya, Osaka, Kyoto, Hiroshima, and other southern regions, is 60 Hertz; in the United States, it is 60 Hertz.
Dual voltage hairdryer
Your hair drier will work in both the United States and Japan if it is dual voltage. The majority of hairdryers sold in the United States are dual voltage and generally will operate at a lower voltage than that of 120 volts.
Adapters for electronics in Japan
You can use an adapter if your electronics do not fit the Type A (two-prong) electrical outlets in Japan. You must verify that the adapter you use does not change the voltage that is delivered; instead, it merely permits your appliance to fit into a Japanese outlet. Check the device’s owners manual before use.
Voltage converter in Japan
The main distinction between an adapter and a converter is the availability of power. An adapter’s role is to ensure your electronics’ plugs fit into foreign plugs, whereas a converter’s purpose is to modify the voltage in an outlet to match that of your equipment.
North American plugs in Japan
Although the power voltage in Japan is lower at 100V as well as a small difference in frequency the great majority of current electronic products designed for the American market is a voltage of 110V and will function perfectly well in Japan.
Foreign Electronics in Japan
If the normal voltage in your region is between 110 and 127V, you can use your electronics in Japan (as is in the US, Canada, and most South American countries). Fluctuation plus or minus 5% are taken into consideration by product manufacturers.
A combination power plug adapter/voltage converter is a possible option if you are traveling with several electrical devices that may be sensitive to power fluctuations.
What adapter do I need for Japan
Its recommended bringing a 3 to 2 prong adaptor. Your devices that use plugs A and B (two verticle prongs) are compatible. Some electrical devices may have a third grounding prong beneath your two vertical prongs. If this is the case you will need this 3 to 2 converter.
