Teruko

Teruko is a feminine Japanese given name. Typically written with kanji such as 照子 (from teru meaning "shine, illumine, reflect" and ko meaning "child"), 曦子, 輝子, or 光子, the name can be formed from other kanji combinations as well, reflecting the flexibility of Japanese naming conventions.

Etymology

The name Teruko is formed by the combination of the element teru, which conveys ideas of brightness or shining, and the suffix ko, frequently used in female names. Traditionally, Japanese names ending in ko were common among aristocratic families and have deeper cultural associations with virtue and beauty.
