Compare the plug shapes, voltage and frequency in Eswatini and Japan, and find out which adapter you need before you travel.

Adapter required

Yes — coming from Eswatini, you will need a travel adapter for Japan. Eswatini uses Type C/Type M/Type N plugs, and Japan uses Type A/Type B, so the pin shapes will not fit any wall socket. Voltages differ (230 V at home vs 100 V abroad), so check the label on each device. Most modern dual-voltage chargers handle the swing without a converter, but heating appliances usually do not.

Voltage converter may be needed. Check your device label — most modern electronics (phones, laptops) support 100–240 V and only need a plug adapter. Hair dryers, kettles, and older appliances may need a step-up or step-down converter.
