Meaning & origin
Kazuko is a Japanese feminine name that saw its peak usage in the United States in 1927, reflecting a broader cultural interest in Japanese names during that era. The name's last recorded year of popularity was 2025, though it has been given only sporadically in recent decades. Its trajectory has been stable but minimal, as it has largely fallen out of common use both in Japan and abroad. The name carries a peaceful meaning rooted in harmony, and its kanji composition is typical of traditional Japanese naming conventions.
Kazuko is a traditional Japanese feminine name composed of two kanji characters. The first character, often 和 (kazu), means 'harmony' or 'peace,' while the second character, 子 (ko), means 'child.' The name was especially popular in Japan during the early Shōwa period, peaking in the late 1920s. It follows a common naming pattern where 子 (ko) is appended to a virtue or aesthetic root.
