Kazuo (カズオ, かずお) is a masculine Japanese given name, formed by combining the element kazu (meaning "one" from the character 一, or "harmony, peace" from 和) with o (meaning "male, man" from 男, or "husband, man" from 夫). While the most common representations are 一雄 (first son or leading man), 一夫 (first man), and 和男 (peaceful man), other kanji combinations are possible, and the name is also written in hiragana or katakana. Etymology and Writing The name illustrates a typical Japanese onomastic pattern: a numeral or virtue prefix followed by a suffix indicating masculinity. The reading kazu for characters meaning “one” or “harmony” reflects the inherent flexibility of Japanese naming, where multiple kanji can share the same pronunciation. The suffix o, derived from words for man or husband, is a common ending for male names. Notable Bearers Many notable Japanese men are named Kazuo.
