Meaning & origin

Nobuo is a Japanese male given name that has seen very limited use in the United States. First recorded in U.S. data in 1913, it reached its peak year in 1921, during a period when Japanese immigration was still relatively new. In recent decades, the name has maintained a stable trajectory, with very few births each year. The name's meaning, derived from kanji meaning "faith" or "trust" combined with "man," reflects traditional Japanese values. As a traditional Japanese name, Nobuo is rarely used outside of Japanese-American communities, contributing to its low U.S. profile but enduring cultural significance.

Nobuo is a Japanese male given name composed of two kanji characters. The first character, 信 (nobu), means "faith" or "trust," while the second character, 男 (o), means "man." Alternatively, 伸 (nobu, meaning "extend") or other homophonous kanji may be used. The name has been in use since at least the early 20th century and remains a traditional choice for boys in Japan.
