Compare the plug shapes, voltage and frequency in Palestine and Japan, and find out which adapter you need before you travel.
Adapter required
Yes — coming from Palestine, you will need a travel adapter for Japan. Palestine uses Type C/Type H 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.

More about plugs in Japan
In Japan, the standard power plug is Type A and Type B. The country runs on 100 volts at 50/60 Hz. That means wall sockets in Japan can be one of 2 different shapes — Type A, Type B, and your plug needs to physically match the socket to fit.
