History & Origin

Hiroko is a genuine Japanese name in romaji, joining hiro, generous or abundant, to ko, child. It was borne by Issei and Nisei women, including those whose families lived through the wartime internment era.

It was never common in the United States, given to only about twenty girls a year at most, appearing among Japanese American families early in the twentieth century. A Hiroko from that time would be a great-grandmother today.

Did you know? Hiroko pairs hiro, broad or generous, with the -ko ending that closed the majority of Japanese girls' names for much of the twentieth century.
