Meaning & origin

Shizuo is a Japanese masculine name that has seen limited but consistent use since the early 20th century. The name first appeared in Social Security records in 1915 and reached its peak popularity in 1920, the only year it appears in the top ranks. Its trajectory has been stable since then, with no significant revival. While it has not ranked in recent decades, its use persists among families seeking a traditional Japanese name with a serene meaning. The name remains extremely rare, with a one-in-N value that is effectively null, meaning fewer than 5 births per year in the United States.

Shizuo is a traditional Japanese masculine name composed of the elements 'shizu' (quiet, still) and 'o' (man, husband). It emerged in the early 20th century, with recorded use in Japan dating to at least 1915. The name was moderately popular in the 1920s, with a peak year of 1920, and has since maintained a stable but low profile.
