Japan to Antigua and Barbuda: Complete Plug & Adapter Guide (2026) No Adapter Needed

Heading from Japan to Antigua and Barbuda? 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 Antigua and Barbuda use Type A/B plugs, so your devices should plug right in. An adapter isn't strictly necessary for this trip.

Voltage is another key difference. Japan uses 100V while Antigua and Barbuda uses 230V. If your device only supports one voltage, using it with the wrong supply could cause overheating or permanent damage. Look for "Input: 100-240V" on your charger. Most modern phone and laptop chargers support this range.

Most modern phone chargers, laptop adapters, and camera chargers are designed to handle 100-240V input, so they'll work anywhere with just a plug adapter. Heat-producing appliances like hair dryers and flat irons are often single-voltage, so check before you plug them in abroad.
