Travel adapter from Japan to Tonga
Compare the plug shapes, voltage and frequency in Japan and Tonga, and find out which adapter you need before you travel.
Adapter required
Yes — coming from Japan, you will need a travel adapter for Tonga. Japan uses Type A/Type B plugs, and Tonga uses Type I, so the pin shapes will not fit any wall socket. Voltages differ (100 V at home vs 240 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.
