Hiroko is a female given name of Japanese origin, composed of the kanji characters "廣" (hiro) meaning 'broad' or 'wide', and "子" (ko) meaning 'child'. This name reflects traditional Japanese values of expansiveness and nurturing. Hiroko was popular among baby girls in Japan during the mid-20th century but has since become less common. However, it remains a timeless choice for parents looking for a name with rich cultural heritage and a pleasant sound.
"Hiroko's popularity as a baby name fluctuated over time, with peaks in the late 1920s and early 1930s (maximum of 14 births in 1925), followed by a decline until the mid-1970s. There was another small peak in the late 1980s (highest being 9 births in 1989) before stabilizing at around 5 births per year since."
