Do I need a converter to travel to Japan? Is the voltage the same as that in China?

Japan is an American socket, and three hole socket needs an adapter;

The voltage in Japan is only 100V, which is just longer than that in China.

The sockets in Japan are two vertical holes, which are basically the same as the electrical appliances we usually use (chargers such as mobile phones and cameras);

However, the notebook computers or other electrical and electronic products we use cannot be used in three hole socket.

Extended data:

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.

Of course, GB sockets can be used in China and Australia.
