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.
Just one thing to note is that most sockets in Japan are two-legged round holes, while those used in China are generally two-legged flat holes or two-legged splayed holes. Although most hotels in Japan provide standard adapters for each country, it is safer to prepare one for yourself in order to prevent shortage.
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.

Precautions for purchasing adapter plugs:
One: Be sure to choose a regular shopping mall, supermarket or specialty store to buy.
Two: Be sure to check whether the product identification is complete and whether there is CCC certification mark.
Three: Check the certificate of conformity and the inspection report issued by the Legal Department. If the inverter product is not included in the compulsory certification, you should check the inspection report issued by the statutory inspection agency when purchasing.
Four: when buying, you must conduct a plug-in experiment. After plugging in the socket, it needs to be in good contact and not loose, so it can be pulled out without too much effort.
