Do I need to bring an adapter to travel to Japan?

You don't need to bring a power converter to travel to Japan. In Japan, the alternating current is 1 10V, and the adaptive voltage of the charger of the electric appliance or mobile phone we bought in China is between 1 10V-240V, so we don't need to carry a power converter when traveling to Japan. However, it should be noted that Japanese sockets are mostly two-legged round holes, while sockets used in China are generally two-legged flat holes or two-legged splayed holes.

Although most hotels in Japan provide adapters of international standards, in order to prevent shortage, it is more reassuring to prepare one yourself. According to the different conditions of voltage and sockets in different countries, sockets can be divided into national standard sockets, British standard sockets, American standard sockets, European standard sockets (also called German standard), South African standard sockets and Italian standard sockets. Among them, the United States, Canada, Japan and Brazil use American standard sockets, so the adapter plug needed for traveling to Japan is American standard sockets.
