Japan to United States: Complete Plug & Adapter Guide (2026) No Adapter Needed

Heading from Japan to United States? Plug types and voltage standards differ between countries, so a little preparation goes a long way. Here's a breakdown of what to expect at the wall socket.

Both Japan and United States use Type A/B plugs, so your devices should plug right in. An adapter isn't strictly necessary for this trip.

The voltage and frequency in United States (120V, 60Hz) are close to Japan (100V, 50Hz/60Hz), so your appliances should work without a converter.

Rather than packing bulky converters, consider buying travel-sized dual-voltage versions of appliances you can't live without. For phones and laptops, all you'll need is the right plug adapter since their chargers almost always support worldwide voltage.
