How to use plugs from Okinawa in Oman
Plugs, sockets, adapters and other information needed for travelling from Okinawa to Oman in this page. If you want a report for other countries, re-start the wizard to find to electric adapters for your trip here.
Quick Chart at-a-glance
|Plugs Type:||A, B, I.||C, G.|
If you are electrical savvy, perhaps the previous chart is all you need. If this is not the case, you can continue reading and discover what the chart is saying!
Plugs and Sockets at each country
In Okinawa the following plugs are used: (includes Tokyo, Kyoto, Osaka, Fukuoka, Nagoya, Nagasaki, Sapporo, Southern Okinawa-hontō, Motobu Peninsula, Northern Okinawa-hontō, Naha.)
|Plug Type A||Plug Type B||Plug Type I|
|Outlet Type A||Outlet Type B||Outlet Type I|
Considerations for Japan
Users living in Japan have commented to us the outlets type "B" are not common, therefore plugs type "B" might not be easy to plug in Japan.
... and in Oman you will use: (includes Muscat, Salalah, Sur, Khasab, Nizwa, Sohar, Ibra.)
|Plug Type C||Plug Type G|
|Outlet Type C||Outlet Type G|
Considerations for Oman
Multiple readers have reported to us only type "G" can be found in hotels in Oman. We decided to keep the type "C" in the database so you can decide at your own discretion.
Take care: Okinawa uses higher voltage than Oman
Your electric devices from Okinawa will be expecting 100 Volts, but Oman grid is of 240 Volts, this is a substantial difference that requires you to take some extra steps in preparation to your trip:
On the positive side, nowadays many devices will switch automatically to the network voltage and they will work just fine, i.e. mobile phone chargers are typically multi-voltage (but please, do actually check your own). It is important that you pay attention to your device's voltage. Connecting electronics to the wrong voltage, in the luckiest of the cases, the device will break or stop working temporarily; but please don't take this lightly, in the worst of the cases electrocution and fire hazards are a real possibility.
An automatic power supply suitable from 100 Volts to 240 Volts.
High-power devices don't usually handle different voltages due to the high-currents involved i.e. anything that its main purpose involves generating heat (or cold) like hair driers, baby bottle warmers, kettles, etc. On the contrary, modern low-power devices are likely to auto-detect and auto-adapt to different voltages i.e. usb chargers, laptop chargers, etc.
A hair-dryer can consume up to 2000 Watts, like the one in the picture above, due to the high power they usually work in one voltage system; this one is suitable for 220-240 Volts systems.
You will need a step down voltage converter a device that can be plugged to 240 volts and it provides an outlet with 100 volts for your Okinawa' device. You will need to pay attention to the maximum power output of the converter and the maximum power consumption of the device.
Different plug systems
Sorry, none of the plugs used in both countries are common. You will definitelly need plug adapters, please continue reading for more information.
Lists of adapters you can use in your travel:
This adapter allows you to use plugs type: A, B, C, D, E, F, I, M into outlets type: G.
This is a very cheap adapter without loose terminal and finger protection; it does have earth pass-though (good); but no good grip because of so many different supported plugs. We recommend to use a more expensive option if available.
This adapter allows you to use plugs type: A, B, D, G, I, M into outlets type: C, E, F, L.
This adapter has a safety protection so you don't plug only one terminal into the adapter while touching the other with your finger, because it is generic, when you buy it pay attention to this safety mechanism. Overall a good adapter that has the earth connection pass-though (notice the metallic connector on the side.)
This adapter allows you to use plugs type: A, B into outlets type: C, E, F, L.
A good and solid adapter with earth connection pass-though; because of its construction, it has a good solid grip; On the negative side, two blades plugs are usually 110v, but the two rounded terminals are typically 220v, so please check your device to be sure they will be able to handle the correct voltage when using this adapter.
Adapters you can buy
You can buy the following multi-purpose adapters from Amazon. Please also take a look at the recommended gadgets for your trip.

No equal Hertz
This is not a big issue. Unless you are using an electric alarm clock or some motors when speed is an issue. Explanation: Some alarm clocks uses the frequency of electricity network to measure time. So, time shifts could be experimented. Almost every home electronic device works perfectly with different Hertz.
