Okinawa adapters have two flat pins that fit into Japan and US outlets. Outlet sockets in Japan are not required to be polarized, whereas US appliance have polarized plugs. In order for US appliances to fit into Japan outlets a polarize adapter is needed.
Adapter plugs allow electrical connections up to 240 volts. An adapter plug does NOT change the current or voltage (this requires a converter) unless your appliance is dual voltage. A non-grounded adapter may NOT be used with appliances that have grounded plugs; for these you will need a grounded adapter. If your hair dryer, curling iron, electric razor is not dual voltage you will most likely need a converter to use your electric. For more information see Going In Style's Adapter and Converter Finder. Many of our customers find it handy to have multiple adaptors while traveling - either to run several appliances simultaneously or simply as a backup. If you think you will need additional adapters for your trip, you can also purchase individual adapters.
Why do I need a North American adapter?
Even though Japan uses North American sockets, the sockets are not required to be polarized. Since devices such as laptops have a polarized plug with one prong wider than the other, you will still need an adapter to use your plug in Japan.

Grounded Adapter Plugs
If you are traveling with a grounded United States dual/multi-voltage appliance or using a grounded Transformer you will need to use a grounded adaptor plug. A grounded United States plug has two flat blades and one round pin. Buy grounded travel adapters if you are taking a laptop that has a three pin plug.
Non-Grounded Adapter Plugs
Going In Style offers non-grounded adapter plugs for use with your voltage converter, transformer, or dual/multi voltage appliance. A non-grounded United States plug has two flat blades.
Computers and Apple Products If you are traveling overseas with a Toshiba, HP, Lenovo, Asus, laptop or Apple device such as an iPad, chances are you won’t need a voltage converter. Most laptops are multi-voltage and will operate on voltages ranging from 100 to 240 volts. However, computers do need to make safe connections to foreign power systems and a surge protector is recommended and you will still need an adapter to use your plug.
