It is not common for Japanese parents to use the “-san” honorific on their children. In Japanese culture, the “-san” honorific is used to show respect and deference to others, and it is typically used when addressing or referring to people who are not family members or close friends. Therefore, using the “-san” honorific on one’s own children would be considered inappropriate, as it would be seen as overly formal and respectful within the context of the familial relationship.
Japanese parents usually use other forms of address when referring to their children. For example, they may use the child’s given name, or they may use a term of endearment such as “chan” or “Kun”. These forms of address help to maintain the appropriate level of familiarity and intimacy within the family relationship. Using the “-san” honorific on one’s own children would be seen as being too distant and formal, and it would not be in line with the norms of the Japanese language and culture.
In summary, Japanese parents do not typically use the “-san” honorific on their children, as this would be considered inappropriate within the context of the familial relationship. Instead, they use other forms of address that are more appropriate and respectful within the family dynamic.
