Extended information

Japanese names refer to Japanese names. The order of Japanese names is the same as that of China, that is, the surname comes first, but the number of words in names is often more than that of Han people. Because Chinese characters brought their own pronunciation when they were introduced, and the powerful influence of Chinese culture at that time made it impossible for the Japanese to give up easily, the Chinese pronunciation of the same Chinese character was also preserved.

Chinese characters in Japanese have two or more pronunciations. The original pronunciation in Japan is called phonetic reading, and the one transformed from Chinese is called training reading. In Japanese names, pronunciation and training are also mixed. In the sense, generally speaking, training and reading are used more in surnames, while pronunciation and reading are used more in names.

most Japanese women's names are Zi (こ), Jiang/Zhi (ぇ), Dai (よ), Mei (み), Xiang/Jia/Hua (か) and ネ/〝. Nowadays, about 9% of young women are named after "Zi".

It is customary for a woman to take her husband's surname after marriage. After Ryoko Nakano married Kawasaki Yamahiro, she was renamed Kawasaki Yoshiko; Song QiJun generation, after getting married, changed his name to Kurimoto Jundai. Now, more and more women are opposed to the husband and wife sharing the same surname, and they have also set up a "meeting against the husband and wife sharing the same surname", arguing that they should still use their own surnames after marriage.
