Mitsuo is a Japanese masculine given name, composed of elements that — across multiple kanji readings — can mean "light man" or "light hero." It is written with a variety of character combinations, most commonly using 光 (mitsu), meaning "light," paired with either 男 (o), meaning "male, man," or 雄 (o), meaning "hero, manly." Other possibilities include characters meaning "full," "third," "beauty," or distinct no‐reading combinations unique to bearers' families — such as Mitsuo written as 満男, 三男, 美津雄, or 己津央, among others.
