Tatsuo is Japanese in Origin.
Tatsuo is a Japanese masculine given name formed from tatsu and the masculine ending -o, typically written with kanji such as 夫 (man/husband), 男 (man), or 雄 (male/hero). Meaning varies by characters: common forms include 龍雄 or 竜男 (“dragon, male/hero”), 辰夫 (“zodiac dragon/time sign, man”), 達夫 (“accomplished/attain, man”), and 立夫 (“stand/establish, man”). The name can also be written in kana as たつお. In romanization, Tatsuo is standard (Hepburn), while Tatuo appears under Kunrei-shiki.
Usage expanded in the Taishō and Shōwa eras, making it familiar among mid-20th-century generations, and it remains a classic though less common for newborns today. Notable bearers include novelist Hori Tatsuo (堀 辰雄), artist Miyajima Tatsuo (宮島 達男), politician Kawabata Tatsuo (川端 達夫), and karate founder Shimabuku Tatsuo (島袋 龍夫). Diminutives include Tatsu and Tacchan. Related names are Tatsuya, Tatsurō, and the feminine Tatsuko.
