My last name is Jay. Japanese names refer to Japanese names. The Japanese take their names in the same order as China, that is, the surname comes first, but the number of words in the names is often more than that in the Han people. The most common words are composed of four characters, such as Masao Kosaka, Tadashi Yoshida and Hideo Fukuda. The first two words are surnames, and the last two words are first names. Three words, such as Takamizawa, the first word is surname, and the second word is first name, so Xie Shiyi is surname.
