Meaning & origin

Sumiko is a Japanese name that saw its peak popularity in the United States in 1927, the peak year according to Social Security data. It was first recorded in 1912. The name has remained stable in usage since then, but it has not been ranked in recent years. While precise one-in-N figures are not available, the name's rarity in modern America reflects a decline from its early 20th-century usage. Sumiko is primarily associated with Japanese heritage.

Sumiko is a Japanese feminine name. The first element 'sumi' (澄) means 'clear, pure' and 'ko' (子) means 'child'. The name was most common in the early to mid-20th century in Japan.
