Rokurokubi (ろくろ首) are fascinating and eerie creatures from Japanese folklore, known for their supernatural ability to stretch their necks to incredible lengths. While they appear as ordinary humans during the day, at night, their true nature is revealed when their necks elongate, sometimes to extreme lengths. Rokurokubi are primarily female, and while they can be mischievous, they are often portrayed as tragic figures, cursed to live a dual existence.

Characteristics of Rokurokubi

1. Neck-Stretching Ability:
   • The defining feature of the Rokurokubi is their ability to elongate their necks during the night. In some stories, their necks stretch so long that they can peer into distant windows or drink from rivers without moving their bodies.
   • This ability often occurs while they are asleep or in a trance-like state, and the Rokurokubi themselves may not always be aware of what they are doing at night.
2. Human Appearance by Day:
   • By day, Rokurokubi appear as normal human women and often live ordinary lives. They may be unaware of their condition or may try to conceal it from others. This makes them different from most yōkai (supernatural creatures) in Japanese folklore, who are more openly monstrous or ghostly.
3. Varied Behavior:
   • In some tales, Rokurokubi are merely playful or mischievous, using their elongated necks to frighten people or spy on others. However, in other stories, they are portrayed as more malevolent, attacking people or drinking their life energy or blood, somewhat like vampires.

Origins and Curses

1. Cursed Women:
   • Rokurokubi are often depicted as women cursed by the gods or by some form of karmic retribution. This curse may result from past misdeeds, such as betraying a spouse, neglecting religious duties, or committing a sin in a previous life.
   • In some cases, women are unaware of the curse until their transformation begins, while in others, they knowingly hide their condition out of shame or fear of rejection.
2. Tragic Figures:
   • Many Rokurokubi stories portray them as tragic figures, cursed to live a life of duality. By day, they are normal women, but by night, they transform into supernatural beings, unable to control their actions or reveal their true selves to others.
   • This duality can lead to loneliness, as they often isolate themselves from society out of fear of being discovered.

Rokurokubi in Folklore

1. Mischief and Scare Tactics:
   • Some Rokurokubi enjoy frightening people with their abilities. They may sneak into homes, peer through windows, or surprise travelers by suddenly appearing with elongated necks. These tales are often light-hearted and focus on the Rokurokubi’s playful and mischievous nature.
2. More Sinister Depictions:
   • In other stories, Rokurokubi are depicted as more dangerous, with a thirst for human life force or even blood. These versions are more akin to vampires, stalking their victims during the night, leaving them drained and weak by morning. This transformation into a more predatory being makes some Rokurokubi feared as dangerous yōkai.
3. The Tale of the Traveling Priest:
   • In one well-known story, a traveling Buddhist priest stays the night at an inn. During the night, he sees a woman’s neck stretch impossibly long to spy on him. Startled, the priest recites prayers, causing the woman’s neck to shrink back. The next day, the woman pretends to know nothing about the incident, but the priest recognizes her as a Rokurokubi and quietly leaves the inn.
4. Variants:
   • Some Rokurokubi are capable of detaching their heads completely from their bodies, allowing their heads to fly around independently. These are sometimes called Nukekubi (抜け首), a variation of the Rokurokubi. Nukekubi are generally more malevolent, often attacking people by night while their bodies remain lifeless.

Symbolism

1. Duality and Secrets:
   • Rokurokubi are often seen as symbols of duality and the secrets people carry. By day, they live normal lives, but by night, their hidden, monstrous nature emerges. This can be interpreted as a metaphor for the hidden sides of human nature or the struggles individuals face in keeping their true selves concealed from society.
2. Transformation and Punishment:
   • In many Rokurokubi stories, the creature’s transformation is the result of karma or divine punishment. This links them to broader themes in Japanese folklore about the consequences of immoral behavior or neglecting one’s spiritual duties. The cursed nature of Rokurokubi serves as a reminder of the importance of morality and self-discipline.
3. Loneliness and Isolation:
   • Rokurokubi are often isolated from society, either by their own choice or as a result of their curse. This isolation is a recurring theme in yōkai folklore, where supernatural creatures exist on the margins of human society, unable to fully integrate due to their otherworldly nature. Rokurokubi embody the pain of living a hidden, secretive life.

Modern Appearances

1. Popular Culture:
   • Rokurokubi have appeared in Japanese films, manga, and anime, where they are often portrayed as either humorous or eerie characters. Their strange and unique ability to stretch their necks makes them memorable figures in both traditional and modern storytelling.
2. Symbol of Transformation:
   • In modern interpretations, Rokurokubi have been reimagined as symbols of personal transformation and duality, reflecting the challenges people face in reconciling their inner and outer selves. This has made Rokurokubi an enduring figure in contemporary literature and media.

Conclusion

The Rokurokubi is a fascinating and multi-layered figure in Japanese folklore, representing both mischief and tragedy. While they may appear as ordinary women during the day, their ability to stretch their necks at night reveals their cursed and secret nature. Whether portrayed as playful pranksters or dangerous predators, Rokurokubi offer a unique reflection on the duality of human existence, the hidden sides of ourselves, and the consequences of past actions. Their stories continue to captivate audiences, both as traditional folktales and as part of modern popular culture.

Description

Rokurokubi is a Japanese Yōkai which look like humans although their neck stretches and becomes very long. The name Rokurokubi (ろくろ首, 轆轤首) may have derived from the word “rokuro” which refers to a potter’s wheel, a water well’s pulley or an umbrella handle which all elongates. 

There is also a type of Rokurokubi which detaches their head from their body entirely called Nukekubi. 

Sometimes it is said that if the body of a Nukekubi is moved while the head is detached they cannot unite again. 

In Classical Literature

Rokurokubi were popular Yōkai which appeared in many different classical stories and are interpreted differently in many. In Sorori Monogatari (曾呂利物語, 1663 CE), there is a chapter called “A Woman’s Wild Thoughts Wandering Around” (女の妄念迷ひ歩く事, Onna no Mōnen Mayoiaruku Koto). In this chapter the head of a woman who is sleeping separates and floats away representing her soul wandering. In the same book a man sees a floating head and chased it with a sword so the head flew home. When the woman wakes up she says “I had a scary dream. I was chased by a man with a sword”.

This has later inspired similar stories such as Shokoku Kyaku Monogatari (諸国百物語, 1677 CE) and Hokusō Sadan (北窻瑣談, 1910 CE).

In the story Kokon Hyaku Monogatari Hyōban (古今百物語評判, 1686 CE) there is a chapter in which the head of an innkeeper’s wife leaves her body and when it reattaches she has a ring-like bruise around her neck which is said to be a sign of the Yōkai.

In nearly all tales the Rokurokubi are female. However in Shousai Hikki (蕉斎筆記) there is a male Nukekubi. 

From the Edo period onward there are tales about people’s neck stretching while they are asleep. It is believed that this is derived from misinterpreted depictions of Nukekubi where it was believed that a string attached the head to the body. When this string was depicted visually people misinterpreted it as an elongated neck.

Similar Creatures

There are similar creatures in other beliefs around the world. In Chinese mythology there are the Hitōban and the Rakutō which both have heads separating from their bodies.

The Palasik, Kuyang and Leyak from Indonesia, Penanggalan from Malaysia and Krasue in Thailand have heads separating from their bodies but with their entrails still attached..

In South American folklore there is a creature called the Chonchon which takes the form of a human head and sucks the life out of people. 

In Malaysian folklore there is also the Manananggal which detaches its torso from the waist up and grows bat wings.
