Meaning & origin

Hatsuko is a Japanese name with a clear and meaningful etymology: 'first child.' It first appeared in U.S. records in 1911, the same year it saw its highest usage, though still at very low frequency. The name has never entered the top 1000 and follows a stable, rare trajectory, with no recorded births in recent years. While it is historically associated with Japan and often given to firstborn daughters, Hatsuko has not seen a revival or presence in any U.S. state's top names. Its rarity gives it a distinctive quality, but its lack of modern usage may make it an unconventional choice today.

Hatsuko is a Japanese name composed of the elements 'hatsu' (first) and 'ko' (child). It was traditionally given to a firstborn child, especially a daughter. The name has been used in Japan since at least the early 20th century.
