Kiyoshiko as a Baby Name. Meaning and Origin of Kiyoshiko

What is the meaning of the name Kiyoshiko ?

The baby name Kiyoshiko is a Female name , 4 syllables long and is pronounced kee-YOH-shee-koh (Japanese IPA: [ki.joɕi.ko]).

Kiyoshiko is Japanese in Origin.

Kiyoshiko is a rare Japanese given name formed from Kiyoshi (a classic element meaning “pure,” “clean,” or “saintly,” depending on kanji such as 清, 潔, or 聖) plus the suffix -ko (子, “child”). While -ko has long marked feminine names, Kiyoshi is traditionally masculine, making Kiyoshiko an uncommon, potentially unisex hybrid. The name can be written with various kanji, e.g., 清子 or 聖子 with an unconventional reading, or compound spellings that explicitly include the Kiyoshi element. Romanization may appear as Kiyoshiko (Hepburn) or Kiyosiko (Kunrei-shiki).

Usage skews modern and creative; Japanese -ko names peaked for girls in the early to mid-20th century and declined thereafter, so Kiyoshiko carries a retro-modern feel. Meanings cluster around “pure/saintly child” or “quiet, serene child.” Related and more common variants include Kiyoko (清子/聖子), Kiyoshi (清/潔/聖), and the masculine Kiyohiko (清彦, “pure lad”). Nickname: Kiyo.
