History & Origin

Shizuo is a traditional Japanese man's name meaning something like 'calm man,' from shizu, 'quiet,' and the masculine suffix o. It entered the American record in the early twentieth century with Japanese immigrant families. Its precise sense depends on the kanji a family chose, so the reading here is one faithful interpretation.

Shizuo appears in the American data around 1920, given to only about fourteen boys in its peak year, reflecting early Japanese immigration rather than any mainstream fashion. A man named Shizuo then would be of a great-grandfather's generation today.

Did you know? The -o that ends Shizuo is a classic Japanese suffix meaning 'man,' seen in many names of its era, while the shizu element means 'quiet' or 'calm.'
