Japan to Marshall Islands: Complete Plug & Adapter Guide (2026) No Adapter Needed
Planning a trip from Japan to Marshall Islands? One of the first things to sort out before you travel is whether your electronics will work at your destination. Power outlets, plug shapes, and voltage standards vary around the world, and Marshall Islands is no exception.
Since Japan and Marshall Islands both support Type A, B plugs, you can use your chargers and appliances without a travel adapter. One less thing to worry about.
On the voltage front, Japan (100V, 50Hz/60Hz) and Marshall Islands (120V, 60Hz) are very similar. You shouldn't need a voltage converter for your electronics.
A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Marshall Islands specifically, look for one that supports Type A/B outlets. USB charging ports built into the adapter are a nice bonus.
