According to a scholar who specializes in studying Japanese Chinese community culture, he discovered after contacting a large number of Japanese Chinese that the names of Japanese Chinese are very distinctive.
According to Japan's "Chinese Herald" report, one of the characteristics of Japanese Chinese names is that they have many birth names. After many Chinese became Japanese citizens, they were still reluctant to let go of their original names when choosing Japanese names for themselves, so they chose a character from their original names or remade their surnames. However, there are many people who still use their original names, such as the person who used to be named Li Lihua. There are not a few Chinese people named Yamaguchi Reika, Yamaguchi Hanako, or Yamaguchi Reiko after becoming Japanese citizens.
The second is that there are many Chinese surnames. When many Chinese people choose surnames for themselves after becoming Japanese citizens, they choose surnames starting with or with Chinese characters, such as Nakagawa, Nakano, Nakahara, etc., which are probably considered popular among Japanese Chinese.
The third is that Chinese people attach great importance to the meaning of the characters in their names. In China, when naming children, the meaning of the name is very particular. For this reason, it is very common to search for the etymology of a word and trace its origin back to ancient times. This cultural custom was not lost when the Chinese became Japanese citizens. Paying attention to the meaning of the words when choosing Japanese names has become a major feature of the Chinese when choosing names.
Some Chinese simply still use their given names, which has become one of the characteristics of Chinese names.
