Travel report

Japan devices in South Korea

Plug adapter

Adapter needed

Expect to need one. Japan uses Type A/B; South Korea uses Type C/F.

Voltage converter

Adapter needed

May be needed for single-voltage devices. Japan is 100V; South Korea is 220V.

What to pack

Your shopping list

  • A Type C/F plug adapter (or a universal travel adapter)

    Your plugs won't physically fit South Korea sockets without one.

  • A voltage converter — only for single-voltage appliances

    South Korea runs at 220V, which can damage devices not rated for it.
