Wylde Wrigge

Tradition: Dutch Mythology
Alternative Names: Wilde Wrigge, Wild Wrigge
Category: Ghost


The Myth

Wylde Wrigge is an evil spirit from Frisian folklore that perversely rewards wicked people with wealth. Rather than punishing them directly, the spirit makes bad people rich so that they become even more godless and ultimately more miserable. Its gifts are therefore a form of spiritual corruption, turning apparent good fortune into a source of moral decline and unhappiness.

The spirit is invoked in a traditional Frisian expression about someone who has become rich through sheer luck: “All his fortune was thrown through the window by the Wylde Wrigge.” The saying reflects the belief that sudden, undeserved wealth may not be a blessing at all, but the work of a malevolent supernatural force seeking to lead its beneficiaries further into wickedness.

Vurige Landmeter

Tradition: Dutch Mythology
Alternative Names: Fiery Land Surveyor
Category: Ghost


The Myth

The Vurige Landmeter, or Fiery Land Surveyor, is a wandering spirit in Dutch folklore. It is the ghost of someone who moved a boundary stone or marker to alter the boundaries of a property. As punishment for this dishonest act, the spirit is condemned to wander eternally while carrying the stone on its back, unable to find rest.

Those who encounter the ghost may hear it lamenting, “Where shall I put it?” A person who knows the legend can answer, “Just put it back where you took it from!” By following this advice, the spirit can return the boundary stone to its original position and finally be released from its wandering. The tale serves as a supernatural warning against tampering with property boundaries and emphasizes that a wrongfully moved marker must be restored before the guilty soul can find peace.

Tamazusa

Tradition: Japanese Mythology
Alternative Names: Tamazusa, 玉梓, Gyokumen
Category: Ghost


The Myth

Tamazusa is a beautiful but treacherous woman in Kyokutei Bakin’s epic novel Nansō Satomi Hakkenden. She becomes a central figure in the events that bring ruin upon the rulers of Awa Province and sets in motion the curse that drives the story of the eight dog warriors. Tamazusa is a favored concubine of Jin’yo Mitsuhiro, lord of Takita Castle, who indulges in drinking and women and allows her to influence his government. Retainers who bribe or flatter her receive rewards, while loyal and capable servants are neglected or dismissed. Among those who benefit from this corruption is Yamashita Sadakane, a powerful retainer who secretly maintains an affair with Tamazusa. Together, they contribute to the collapse of Mitsuhiro’s rule. Sadakane eventually tricks his enemies into killing Mitsuhiro, seizes Takita Castle, and takes Tamazusa as his wife.

Sadakane’s tyranny provokes resistance, and an army led by Satomi Yoshizane eventually captures Takita Castle. Sadakane is killed by his own defecting retainers, and Tamazusa is brought before the victors to answer for her role in the corruption of the former lord’s government and her relationship with the traitor. She defends herself by arguing that, as a woman, she had little control over her circumstances and that she became Sadakane’s wife only after Mitsuhiro’s death left her without a home. Her arguments fail to persuade Kanawan Hachiro, who condemns her as a deceptive woman whose outward beauty conceals an evil heart. Yoshizane briefly considers sparing her, moved by her beauty and pleas for mercy, but Hachiro insists that her crimes demand punishment. Yoshizane ultimately orders her execution. Enraged, Tamazusa curses Yoshizane and Hachiro, declaring that they will suffer ruin and that she will lead their descendants toward the path of beasts and worldly desires. She is beheaded, but her hatred survives her death and becomes the source of a lasting supernatural curse.

Tamazusa’s vengeance continues to affect the Satomi family long after her execution. When Hachiro later commits seppuku, the shadow of a woman believed to be Tamazusa’s vengeful spirit clings to his son, Kanawan Daisuke, although only Yoshizane can see it. In time, Tamazusa’s spirit takes the form of a female tanuki named Gyokumen. The transformed spirit raises an orphaned puppy while bathing it in her resentment, and the dog is eventually taken into the Satomi household. Named Yatsufusa, it grows into a powerful animal and becomes the beloved companion of Yoshizane’s daughter, Fusehime. Through this deception, Tamazusa’s curse enters the Satomi family itself. Her vengeance ultimately sets the stage for the adventures of the eight dog warriors, each associated with a jewel representing one of the eight virtues of benevolence and righteousness. Thus, Tamazusa’s death marks not the end of her influence but the beginning of the supernatural trials that shape the epic’s central story.

Iwafuji

Tradition: Japanese Mythology
Alternative Names: Iwatou, 岩藤
Category: Ghost


The Myth

Iwafuji is a notorious female villain in Japanese jōruri and Kabuki theatre, best known for her role in Kagami-yama Kokyō no Nishikie. She serves as a lady-in-waiting to Ohime, the daughter of Minamoto no Yoritomo, and conspires with her brother, Kenzawa Danjō, to seize power within the household. Driven by jealousy toward Onoe, a senior retainer who enjoys the princess’s trust, Iwafuji uses cruel schemes to humiliate her rival and ultimately drive her to suicide. Iwafuji’s triumph is short-lived, however, as Onoe’s maid, Ohatsu, avenges her mistress by killing the villainous lady-in-waiting. Iwafuji became a celebrated theatrical villain, and her character was reportedly inspired by real ladies-in-waiting in the households of powerful feudal lords. When the actor Onoe Matsusuke I played Iwafuji in 1805, rumors spread that the performance portrayed a senior woman of the women’s quarters at Edo Castle, prompting an investigation by the town magistrate’s office.

In later plays that continue Iwafuji’s story, she returns from the dead as a vengeful ghost. One prominent version appears in Kagami-yama Gonichi no Iwafuji, also known as Kotsuyose no Iwafuji, written by Kawatake Mokuami and first performed in 1860. In this story, Iwafuji’s remains are left in a horse burial ground after her death at Ohatsu’s hands. Her spirit lingers there until Ohatsu, who has earned praise for her loyalty and become the second Onoe, visits to pray for the repose of her predecessor’s soul. A dark flame suddenly rises, and scattered bones gather together before flesh begins to return to the corpse. Iwafuji reappears with disheveled hair and decaying skin, greeting Ohatsu with a curse and promising to haunt the Taga family, torment Hanazono-hime, and assist Mochizuki Danjō in his plot to seize power. Although a protective sword briefly drives her away, she returns in a beautiful, almost supernatural form, carrying a parasol and playing with butterflies as she floats through the air above the cherry blossoms.

Iwafuji continues her revenge by helping the conspirators undermine the Taga household. When Hanazono-hime falls ill under the influence of a malevolent spirit, the villains falsely accuse the second Onoe of cursing her. Iwafuji disguises herself as Danjō and uses forged documents and accusations to corner Onoe, even repeating the humiliation inflicted upon the first Onoe by beating her with a sandal. The ghost’s deception is eventually exposed when Sekiya uses a shrine of Kishimojin to make her vanish and restore the palace to its proper state. Iwafuji later confronts Onoe again, wielding a snake-eye umbrella and renewing her curses, but Inukiyo drives her away by presenting the sacred image of Kishimojin. This time, her spirit finally disappears, and her body returns to a skeleton before shattering into pieces. The play’s spectacular scene in which the resurrected Iwafuji floats through the air is known as Fuwa Fuwa and remains one of the story’s theatrical highlights. Through her resurrection and repeated attempts at revenge, Iwafuji becomes a figure of relentless malice whose grudges persist beyond death.

Karaginu

Tradition: Japanese Mythology
Alternative Names: Karaginu, 唐衣
Category: Ghost


The Myth

During the reign of Emperor Toba, Ishikawa Juro Yoshitoshi and his wife Ukihashi, who lived in Hino Village south of Kyoto, prayed to Kannon Bodhisattva for a child. Ukihashi eventually gave birth to triplets, born during the hours of the tiger, snake, and monkey. Ashamed of having three children at once, she concealed the birth from her husband and entrusted two of the girls to a wet nurse, keeping the third to raise herself. Years later, three beautiful women named Han’i, Tamaki, and Kono Kimi were brought to serve Emperor Toba by two of his consorts, Taikenmon’in and Kōyōin. Han’i gained the emperor’s particular affection and became pregnant, provoking the jealousy of Bifukumon’in, the emperor’s favorite. Bifukumon’in plotted against her rival, using false accusations to have Han’i arrested. Her companions, Kono Kimi and Tamaki, were arrested alongside her. All three women were stripped, tortured, and killed by officials acting under Bifukumon’in’s influence. Han’i’s death was falsely presented as suicide, and their bodies were buried at Shimizu Hill, at a place known as Kemonozuka, or Beast Mound.

The murdered women returned as vengeful spirits, tormenting their enemies and members of the imperial family. Their curse first brought about the deaths of a mountain ascetic’s wife and the ascetic himself. In 1153, their combined spirits took the form of a monstrous creature that appeared above the Imperial Palace, terrifying the young Emperor Konoe with its cries. The monster possessed the head of a monkey, the limbs of a tiger, and the tail of a snake, while its shriek resembled the cry of the nue. Minamoto no Yorimasa and Ino Hayata eventually shot the creature down, but its death did not end the women’s vengeance. Dark flames burst from its wounds and vanished into the clouds. The sisters’ spirits later appeared to Ishikawa Yoshikane, a nephew of Yoshitoshi, revealing their true origins and explaining that they had been falsely accused. Han’i was identified as Yoshitoshi’s daughter, born during the hour of the snake and given the childhood name Asaji. The spirits continued their pursuit of revenge, taking the forms of animals associated with the hours of their births. The slaying of the nue was therefore only one episode in their prolonged supernatural campaign against those who had wronged them.

Osayo

Tradition: Japanese Mythology
Alternative Names: Sayogoromo Osayo, 小夜衣おさよ
Category: Ghost


The Myth

Osayo is a tragic woman who becomes a vengeful ghost in Konomaboshi Hakone no Shikabue, a Kabuki play written by Kawatake Mokuami and first performed in 1880. Born into the Iozaki family in Shizuoka, she is a beautiful and dutiful woman married to Iwabuchi Kurobei, a former samurai. After the Meiji Restoration, Kurobei’s business ventures fail and his debts mount, forcing Osayo to sell herself to a brothel called Ebiya in Odawara to support him. Working under the name Sayogoromo Osayo, she quickly becomes one of the most popular courtesans in the region. Despite attracting the attention of Gantetsu, a monk and regular customer who knows her history, Osayo remains devoted to her husband and refuses to abandon him. Her loyalty persists even as she entrusts her young daughter, Omitsu, to the care of an old acquaintance, the sword sharpener Ryosuke, while continuing to work to support Kurobei.

One day, Kurobei visits Osayo and claims that his debts have become so overwhelming that he intends to take his own life. When debt collectors arrive demanding more than one hundred yen, Osayo is desperate to help him. The innkeeper Jubei and his wife Osen take pity on the couple, lending the money needed to settle the supposed debt. Osayo later discovers that the entire scene was a deception: the collectors were Kurobei’s accomplices, and he had squandered the money she earned on his mistress, Yamaneko Okitsu, and his own indulgences. Devastated by his betrayal, Osayo is taken by Jubei to Hakone to recover. There, at the Fukuzumi Inn, she encounters both her former fiancé, Atsuhara Isonosuke, and Kurobei with Okitsu, who mock her suffering. Overcome by rage, Osayo confronts the pair with her mother’s keepsake, a Muramasa dagger. Kurobei wounds her while resisting, then attempts to kill her at Okitsu’s urging. As she dies in the mountains of Hakone, Osayo declares that her resentment will not disappear simply because people in the modern age deny the existence of ghosts. Her death marks the beginning of her transformation into an onryō, a spirit consumed by vengeance.

After returning to Tokyo, Kurobei claims that Osayo was murdered by bandits and takes Okitsu as his second wife. He soon falls gravely ill, however, and is tormented by visions of Osayo appearing in the shadows and accusing him of her murder. When the dagger he sold comes into the possession of Isonosuke, and Kurobei’s younger brother Yoshichi begins questioning him, Kurobei finally confesses his crime. He resolves to commit seppuku, hoping to preserve his family’s honor and atone for his actions, but Osayo’s ghost continues to appear before him. She acknowledges that his remorse is justified but refuses to let him escape through suicide, declaring that her hatred will not be satisfied until she has killed him herself. His delirium intensifies, and an attempted exorcism led by Gantetsu descends into violence. Clutching the dagger, Kurobei attacks Gantetsu, while Yoshichi wounds Kurobei during the struggle. Driven into complete madness, Kurobei flees and attacks the former accomplices who helped deceive Osayo, as well as Okitsu. Okitsu, who has discovered that she is Ryosuke’s long-lost daughter and regrets her past actions, accepts her fate and dies by Kurobei’s blade. Yoshichi takes responsibility for Kurobei’s crimes before the authorities, leaving Kurobei ruined and alone. The play reflects the anxieties of the Meiji period, when supernatural apparitions were increasingly explained as symptoms of nervous disorders, yet ghost stories continued to portray vengeful spirits with terrifying immediacy.

Ni Gui

Tradition: Chinese Mythology
Alternative Names: 溺鬼, Shui Gui (水鬼), Luo Shui Gui (落水鬼), Shui Jin Gui (水浸鬼), Drowning Ghost, Drowned Spirit
Category: Ghost


The Myth

Ni Gui, or the Drowning Ghost, is the spirit of a person who died by drowning. Also known as Shui Gui or Water Ghost, it is believed to haunt rivers, lakes, and other bodies of water. Some descriptions portray it with green or red eyes and unnaturally strong, slippery skin, as though its body were coated in oil. It can swim through water as swiftly as a fish and possesses strength said to equal that of ten adult men.

The Drowning Ghost is feared for its attempts to pull living people beneath the water and drown them. According to traditional beliefs, spirits who died by drowning must find a living person to take their place before they can be reborn. This process is known as qiu ti, or seeking a replacement. The ghost may call out a person’s name from beside a river; anyone who answers risks being lured into the water and drowned. The Chinese work Beimeng Suoyan records a related belief that the spirits of the drowned tempt people along riverbanks, seeking to draw them to the same fate.

Not all tales portray the Drowning Ghost solely as a threat. In the traditional story The Fisherman and the Drowning Ghost, a fisherman bargains with the spirit, asking it to help him become wealthy. Another account in Yizhi Lu describes a drowning ghost that assists a fisherman by driving fish towards his nets. The spirit is also said in Wangwang Lu to be capable of transforming into a sheep. Nevertheless, the belief that drowned spirits seek replacements remains central to many stories about these restless dead, whose unnatural deaths prevent them from moving on to rebirth.

Akana Soemon

Tradition: Japanese Mythology
Alternative Names: Akana Sōemon, 赤穴宗右衛門
Category: Ghost


The Myth

Akana Soemon is a samurai and military scholar who appears in “The Chrysanthemum Vow,” the second story in Ueda Akinari’s collection of supernatural tales, Ugetsu Monogatari. Soemon serves En’ya Kamonnosuke, the lord of Tomita Castle in Izumo Province, and is sent as a secret messenger to Sasaki Ujitsuna in Ōmi. During his absence, Amago Tsunehisa launches an attack, kills Kamonnosuke, and seizes the castle. When Soemon urges Ujitsuna to oppose the Amago clan, Ujitsuna refuses and confines him to prevent his departure. Soemon eventually escapes, but falls gravely ill while travelling home. He finds shelter in Harima Province, where he meets Hasebe Samon, a devoted scholar who nurses him with medicine and food despite the danger of contagion. Deeply moved by Samon’s kindness, Soemon promises to repay him and the two men become close friends, eventually swearing an oath of brotherhood. Since Soemon is five years older, he asks to be treated as Samon’s elder brother, and Samon’s mother welcomes him affectionately.

When Soemon prepares to return to Izumo, he promises to visit Samon again on the ninth day of the ninth month, the Double Ninth Festival. Samon trusts his friend’s word and eagerly awaits his return, preparing food, drink, and chrysanthemums for the occasion. As evening falls, Soemon finally appears, but he remains strangely silent and refuses to eat or drink. At last, he reveals the truth: he is no longer among the living and has returned only as a spirit to fulfill his promise. After reaching Izumo, Soemon discovered that the people of the province had largely submitted to the Amago clan and that his former lord’s loyalty had been forgotten. His cousin Akana Tanji introduced him to Tsunehisa, but Soemon found little reason to remain in the service of a suspicious ruler. When he announced his intention to leave and honor his oath to Samon, Tsunehisa ordered him confined within Tomita Castle. Trapped until the appointed day, Soemon feared that failing to return would betray his friend’s trust. Remembering the saying that the soul can travel a thousand miles in a single day, he took his own life with his sword and sent his spirit across the distance, borne by a shadowy wind, to keep his promise. After explaining what happened, he urges Samon to care for his mother before vanishing.

Overcome with grief, Samon entrusts his mother to the care of the Sayo family and travels to Izumo to avenge Soemon’s death and defend his friend’s honor. He confronts Akana Tanji, condemning the family’s disregard for the kindness once shown to them by Soemon’s lord and praising Soemon for preserving his oath even at the cost of his life. Samon then draws his sword and kills Tanji before departing. When Amago Tsunehisa learns what has happened, he is so moved by the brothers’ extraordinary loyalty that he orders no pursuit. The tale celebrates the sacred force of friendship and the determination to keep one’s word, even beyond death. Its story is adapted from the Chinese tale “Fan Juqing’s Relationship with Chicken and Millet,” from the collection Stories to Caution the World, compiled by Feng Menglong, with the setting transferred to Japan’s Sengoku period.

Ipponmatsu-onna

Tradition: Japanese Mythology
Alternative Names: 一本松女, The One-Pine Woman
Category: Ghost


The Myth

Ipponmatsu-onna, meaning “One-Pine Woman,” is a female supernatural figure associated with a solitary pine tree. Her descriptions vary between accounts, and it is uncertain whether she originates from an established local legend or was popularized through modern reference books about Japanese yōkai. In Japanese Yokai Encyclopedia by Ariyuki Sato, she is presented as a creature associated with Chiba Prefecture. She is depicted as a naked woman with only one leg, covering her chest with both hands. She stands beside a pine tree, beckoning to passersby before dragging herself along and biting off a single pine branch.

A different description appears in The Complete Encyclopedia of World Yokai, where the Ipponmatsu-onna is portrayed as a gigantic, ghostlike woman who rises beside a solitary pine tree. According to this account, she is formed from the ominous energy of the tree and stands alone at its base at dusk. Rather than attacking people, she appears as a lonely and unsettling presence. Another interpretation identifies her as the spirit of a woman who hanged herself from the pine tree, linking her apparition to the place of her death.

The origins of these descriptions remain uncertain. It is not clear whether either version derives from an older oral tradition or historical written source, and the details may have been created or embellished in children’s books and modern yōkai publications. Consequently, the Ipponmatsu-onna is best understood as a figure whose modern depictions combine the imagery of a solitary pine tree, a strange female apparition, and the atmosphere of a haunting at dusk.
