Female Ninja Name Generator

A female ninja is a kunoichi, and the only one history names with confidence is Mochizuki Chiyome, the widow who ran a network of shrine maidens, travelling entertainers and servants as spies for the Takeda clan. Like all Japanese names of the Sengoku period, hers runs family name first: Mochizuki is the house, Chiyome the given name. The great ninja families (Hattori, Fuma, Momochi, Fujibayashi, Igasaki, Kosaka, Sugitani, Tateoka, Shimotsuge) and the regions of Iga, Koga and Togakure make natural surnames, and a kunoichi working under cover would carry an ordinary name of the day: short two-syllable ones like Sayo, Tae, Chiyo and Kiku, or the honorific O- forms (Oyuki, Okiku, Otsuru) that every Edo townswoman used.

Fiction adds a second layer. Anime and game kunoichi lean on nature words with an edge: Kasumi (mist), Ayane (colorful sound), Kaede (maple), Hotaru (firefly), Tsubaki (camellia), Kagero (heat haze), Oboro (hazy moon), Shizuka (quiet), Momiji (autumn leaves). Many also answer to a code name, a single striking word or a phrase like Kurohebi (black snake), Benihime (crimson princess) or Kage no Tsubasa (wings of shadow), which is how a shinobi would be known inside her village.

The list mixes all three, so you can pick a plausible spy, a game heroine or a legendary assassin.
