Your plugs fit some compatible outlets in Japan, but not every listed socket design. An adapter may be needed for the outlet you encounter. A grounded three-prong plug needs a suitable grounded connection; do not remove its ground pin or assume a two-pin adapter provides earth.

Voltage & frequency

🇦🇬 Home

230 V

60 Hz

🇯🇵 There

100 V

50/60 Hz

Lower voltage
Japan uses 100 V, lower than the 230 V in Antigua and Barbuda. An input rating of "100–240V" covers the listed supply voltage; you still need a suitable plug or adapter. Single-voltage devices may run weakly or not at all.

The destination may use a different frequency (60 → 50/60 Hz). Check your device's input rating for the local frequency; a plug adapter does not change it.

  • Phone charger

    Basically all modern USB chargers are 100–240V. Adapter only.

  • Laptop charger

    Look for "100–240V" on the brick. It's almost always there.

  • Camera battery charger

    Usually dual voltage. Check the tiny print.

  • Electric toothbrush

    Many are dual voltage, some are not. Check the base.

  • Electric shaver

    Often dual voltage. Often. Check.

  • CPAP machine

    Most modern ones auto-switch, but confirm before you rely on it to breathe.

  • Hair straightener / curler

    Some have a voltage switch. Many don't. Fire is a bad hairstyle.

  • Hair dryer

    Usually single voltage and very power-hungry. Buy a travel one or use the hotel's.

  • Kettle / coffee maker

    Single voltage, high wattage. Leave it home. Buy coffee abroad like a local.

  • Anything with a heating element

    If it gets hot on purpose, assume it's single voltage.

Plugbert's note on Japan
Japan is split in two: eastern Japan (Tokyo) runs at 50 Hz and western Japan (Osaka) at 60 Hz. A grounded three-prong plug needs a suitable grounded connection; do not remove the ground pin or assume a two-pin adapter provides earth.
