History & Origin

Hisao is a traditional Japanese boy's name, most often understood as long-lasting joined to o, man, a hopeful name wishing a long life. In the United States it belonged largely to the Issei generation, Japanese immigrant families of the early twentieth century whose community later faced the wartime internment of Japanese Americans. Written with Japanese characters, its precise meaning depends on those characters, but the long-life reading is best known.

Hisao was always rare in American records, given to only about twenty boys a year even at its high around 1922, and it remained a heritage name. A boy named Hisao then would be a great-grandfather today.

Did you know? The -o ending, meaning man or hero, closes many traditional Japanese boy names, so Hisao reads clearly as a classic name of its generation carrying a wish for long life.
