The Iso-Onna (磯女 or "beach rock woman") is a yōkai found in fishing villages all over Japan. She has many different names, and all of them seem friendly enough:

  • Iso-Onago = rock girl
  • Umi-Onna = ocean woman
  • Umi-Hime = ocean princess
  • Umi-Nyoubo = ocean wife


  • In the 2007 anime version, she is one of the 47 Yōkai Warriors. She's the representative of Nagasaki. And her mark is located on her baby's diaper.
