Natsuko is Japanese in Origin.

Natsuko is a Japanese feminine given name formed from Natsu and the suffix -ko ("child"). Its meaning depends on the kanji: the common 夏子 reads as "summer child," while forms such as 奈津子, 菜津子, and 那津子 use phonetic or ornamental characters suggesting serenity, nature, or harbors (津). It may also be written in hiragana (なつこ) or katakana (ナツコ). Pronounced NAH-tsu-koh, Natsuko is rendered in Roman letters as Natsuko under standard Hepburn.

The -ko ending rose to prominence from the Taisho through mid-Showa eras, making Natsuko feel classically mid-20th-century; usage declined after the 1980s as softer endings gained favor, though the name now enjoys a modest retro-chic revival. Diminutives include Natsu and Nacchan. Related summer-themed names are Natsumi, Natsuki, and Natsuha. Across Japan and the diaspora, Natsuko signals seasonal warmth and a traditional, graceful image grounded in literate kanji choice.
