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

More about plugs in Oman
In Oman, the standard power plug is Type G. The country runs on 230 volts at 50 Hz. That means every wall socket in Oman is the same shape — Type G, and your plug needs to physically match the socket to fit.
