◆ The legend
Among the oni who served Shuten-doji, the chief of Mount Oe, the one known as his top follower is Ibaraki-doji. When Minamoto no Raiko and his four retainers stormed Mount Oe, many oni were slain, but Ibaraki-doji is often said to have escaped, and several stories tell what happened next. Where it came from is not settled: one theory says Settsu's Ibaraki (in today's Osaka Prefecture), another says Echigo (today's Niigata), and there are others.
The best-known Ibaraki-doji story is about an arm. In the capital, one of the four retainers, Watanabe no Tsuna, cut off the oni's arm, and later, it's said, the oni came back in human disguise to take it home. Because it so often appears as a beautiful woman or an old woman to get close to people, Ibaraki-doji is frequently pictured as an oni with a gift for disguise, and it became a familiar figure on the Noh and Kabuki stage.
