Travel adapter from Japan to Nigeria
Adapter Required
Yes — coming from Japan, you will need a travel adapter for Nigeria. Japan uses Type A/Type B plugs, and Nigeria uses Type G, 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.
