Adapter required

Yes — coming from Japan, you will need a travel adapter for São Tomé and Príncipe. Japan uses Type A/Type B plugs, and São Tomé and Príncipe uses Type C/Type F, so the pin shapes will not fit any wall socket. Voltages differ (100 V at home vs 230 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.
