The order of Japanese names is the same as that in China, that is, the surname comes first and the given name comes last, but the number of characters in the name is often longer than the number of characters in my Han name. The most common ones consist of four characters, such as: Masao Kosaka, Masaichi Yoshida, Hideo Fukuda, etc. The first two characters are the surname, and the last two characters are the first name. However, since the number of characters for the surname and the given name is not fixed, it is often difficult to distinguish between them. Therefore, it is necessary to understand clearly with the visitor in advance. In formal occasions, the surname and the given name should be written separately, such as "Nikaido Susumu", "Fujita" "しげる" etc.
Generally, people are called by their last name orally, and in formal situations, they are called by their full name. Japanese names are often written in kanji, but the pronunciation is completely different. For example: "山本" should be read as Yamamoto, "三岛" should be read as Mishima, and "日下" should be read as Kusaka.
