Nobuko is Japanese in Origin.

Nobuko is a Japanese feminine given name pronounced NOH-boo-koh. It combines Nobu with the suffix -ko, “child.” Meaning depends on the kanji: 信子 conveys “faithful/trustworthy child,” 伸子 “growing/expansive child,” 宣子 “proclaiming/clear-voiced child,” 延子 “enduring/long-lived child,” and 暢子 “unfettered/smooth-flowing child.” It may also be written in kana as のぶこ or ノブコ.

Once favored among noblewomen - the -ko ending was standard in the Heian court - the name spread broadly from the Meiji era and peaked nationwide through the Taishō and early Shōwa periods, giving it a classic mid‑century feel today. Notable bearers include Princess Nobuko of Mikasa, the celebrated violist Nobuko Imai, and actress Nobuko Otowa. Variants lie chiefly in the kanji choice; the romanized form is consistently Nobuko. Common diminutives are Nobu or Nobu‑chan.
