Meaning & origin

Eiko is a Japanese feminine name that entered U.S. records around 1915 and saw its peak usage in 1921. Despite its early appearance, it has never reached the top 1000 nationally, and the latest data from 2025 shows a stable but rare presence. The name's meaning varies with the kanji selection, often conveying prosperity or blessings. Its limited use in the U.S. reflects its strong cultural ties to Japan, where it remains a traditional choice.

Eiko is a Japanese name that can be written with various kanji combinations. The first character 'Ei' often means 'prosperity' or 'blessing', and 'ko' means 'child'. It has been used in Japan for over a century, appearing in records as early as 1915. The name enjoyed modest popularity in the early 20th century, particularly in the 1920s.
