Meaning & origin

Tatsuo is a traditional Japanese masculine name that has seen limited use in the United States. According to Social Security data, it was first recorded in 1915 and reached its peak popularity in 1916, after which it has remained stable but rare. The name has never appeared in any top states rankings, reflecting its niche appeal primarily within Japanese-American communities. Its meaning, rooted in the auspicious dragon symbol, connects it to strength and cultural heritage. Despite its low frequency, Tatsuo carries a sense of history and distinctiveness, appealing to families seeking a name with deep Japanese roots.

Tatsuo is a traditional Japanese masculine name composed of two kanji: tatsu (龍, 'dragon') and o (夫, 'man') or o (雄, 'male, masculine'). The dragon is a powerful, auspicious symbol in Japanese culture, associated with strength and good fortune. The name has been used in Japan for centuries and was notably popular during the early Showa period, with a peak in 1916 according to U.S. Social Security data. It exemplifies the Japanese naming tradition of combining characters with positive attributes.
