Furthermore, "Karako" as it is inscribed in the September 531 entry of the "Nihonshoki" refers to a 'child born of union between a Japanese man and a woman from a neighboring country'; since Karako is a common term used to describe people of mixed Wa (Japanese) and Korean descent, it is hard to believe that it specified any individual.
