History & Origin

Natsuko is a traditional Japanese girl's name most often built from summer and ko, child. In the United States it belonged largely to the Issei and Nisei generations, immigrant families and their American-born daughters in the early decades of the twentieth century, a cohort whose lives were later marked by the wartime internment of Japanese Americans. Written in Japanese with characters, its precise meaning depends on those characters, but the summer-child reading is the best known.

Natsuko was always rare in American records, given to only about twenty girls a year even at its high around 1925, and it remained a heritage name rather than a mainstream one. A girl named Natsuko then would be a great-grandmother today.

Did you know? The -ko ending, meaning child, closes many traditional Japanese girl names, so Natsuko reads clearly as a classic name of its generation, often given to daughters born in summer.
