Before plugging in your electronics abroad, always double-check the voltage label. If it says “100-240V, 50/60 Hz”, your device will work on both 120V and 220-240V power sources without a converter. This is common for tablets, laptops, cameras, and rechargeable toothbrushes.

More About the Northern Mariana Islands
The Northern Mariana Islands are one of those spots that feel completely off the tourist radar—which is exactly what makes them special. Think emerald-green volcanic peaks rising out of deep blue Pacific waters, World War II relics hidden in the jungle, and barely-touched beaches that look like they belong on a movie set.
Saipan is the main island, and it’s where most of the action happens—if you can call it action. You’ll find small towns, friendly locals, and some seriously good diving spots. It’s not flashy, but it’s raw and real—and perfect if you’re looking to unplug.
The Northern Mariana Islands uses the same plugs and outlets as Japan.
