Teruko

Meaning & origin

Teruko is a Japanese feminine name that saw its highest popularity in the late 1920s, with a peak year in 1927. It first appeared in U.S. records in 1913 and has since maintained a stable but low presence. The name's rarity is reflected in its current one-in-N (undefined) ranking, and no states have recorded significant usage in recent decades. Like many traditional Japanese names ending in -ko, Teruko evokes a classic, pre-modern aesthetic, though it remains far less common than names like Haruko or Keiko. Its exact etymology is unclear, but the suffix indicates a name long favored in Japanese families, particularly during the early 20th century. Despite its decline in frequency, Teruko retains cultural resonance as a distinctly Japanese name with a gentle, melodic sound.

Teruko is a Japanese feminine name formed with the suffix -ko 'child,' a common element in traditional girl names. The first syllable Teru may derive from the verb teru 'to shine' or from other roots, but the intended meaning is not transparent. The name was most popular in the early 20th century, particularly during the Taishō and early Shōwa periods, and has since become less common.
