The Long Neck Woman, or “Rokurokubi”, is a Japanese urban legend about female creatures that look and act like normal humans. But at night their necks grow longer and longer, freeing their heads to move around almost independently from their bodies. Most Rokurokubi are young, attractive women, and they take pleasure in scaring regular humans.
Some Long Neck Rokurokubi actually prefer to live their lives pretending to be a human. Although they may appear to be completely normal people, every night, their necks grow and grow, getting longer and longer, stretching out through windows in search of human prey.
Sometimes, the Long Neck Woman will get so tired searching for her prey all night long that she forgets to retract her neck and falls asleep with her neck completely stretched out. During the day, the Rokurokubi has one giveaway sign – she will have pale stretch marks on her neck.
There is also another, more sinister form of Rokurokubi. This version is called Nukekubi or “Removeable Head Woman”. She has a head that completely detaches from her body. The disembodied head then flies around in the air at night searching for humans to eat.
These Nukekubi attempt to hide their bodies at night, and can be killed if their bodies are discovered while the heads are not attached. In fact, if you find a Nukekubi’s body without a head, you should hide the body so that she can never find it.
