Hiroko is Japanese in Origin.

Hiroko is a Japanese feminine given name formed from hiro + ko, where ko (子) means “child,” a classic suffix in girls’ names. The first element hiro can be written with various kanji - 広/弘/宏/博/裕/寛, among others - conveying senses such as “wide/broad,” “expansive,” “learned,” “prosperous/abundant,” or “generous.” As a result, Hiroko’s meaning varies with the characters chosen, often interpreted as “broad-minded child,” “prosperous child,” or “kind, generous child.”

Use of -ko rose from late Meiji through the Taishō and early Shōwa eras, when it symbolized refinement and modernity; the style peaked mid-20th century and has since declined, giving Hiroko a timeless, vintage feel rather than contemporary trendiness. Common written variants include 広子, 弘子, 宏子, 博子, 裕子, and 寛子, as well as phonetic ひろこ (hiragana) and ヒロコ (katakana). Related names built on hiro include Hiromi, Hiroe, Hiroka, and Hiroyo.
