Ubagabi

Tradition: Japanese Mythology
Alternative Names: 姥ヶ火, 姥火, Old Woman’s Fire
Category: Flame


The Myth

The Ubagabi, meaning “Old Woman’s Fire,” is a mysterious ghost light from Japanese mythology, associated with Kawachi Province, now part of Osaka Prefecture, and Tanba Province, in northern Kyoto Prefecture. It typically appears on rainy nights as a glowing ball of fire approximately thirty centimetres in diameter. In some accounts, the flame can suddenly rush toward a traveller and strike them in the face before transforming into a strange, chicken-like bird. When the creature flies away, it returns to its original form as a ball of fire.

One legend from Kawachi tells of an old woman who stole oil from Hiraoka Shrine. As punishment for her theft, she was transformed into the Ubagabi, condemned to wander as a supernatural flame. According to another account, recorded in Ihara Saikaku’s collection of tales, the fire could travel approximately four kilometres in an instant. Anyone whose shoulder it brushed was said to die within three years. However, the Ubagabi could supposedly be made to disappear by calling out the words “abura-sashi,” meaning “oil pourer,” a reference to the theft that caused its transformation.

Another legend, associated with the Hozu River near Kameoka in Kyoto Prefecture, tells of an old woman who accepted money from parents on the promise that she would take them to people they wished to visit. Instead, she threw their children into the river. Eventually, a flood drowned the woman, which was interpreted as divine punishment for her crimes. After her death, a mysterious flame began appearing near the river, and people came to know it as the Ubagabi.

The Ubagabi also appears in Toriyama Sekien’s illustrated collection Gazu Hyakki Yagyō, where its supernatural flames contain the face of an old woman. The accompanying description associates the creature with Kawachi Province. Across these different accounts, the Ubagabi is linked to wrongdoing and punishment, its ghostly fire serving as the lingering manifestation of an old woman’s crimes.

Osabi

Tradition: Japanese Mythology
Alternative Names: –
Category: Flame


The Myth

Osabi is a mysterious supernatural fire said to appear on rainy nights at Sankakuike Pond in the Nobeoka region of Miyazaki Prefecture, Japan. The phenomenon is described as two separate flames that emerge near the water and appear to struggle or fight with one another. Sightings were reportedly known in the area until around the middle of the Meiji era.

According to local legend, the strange lights originated from a quarrel between two women over the lending and borrowing of an osa, a comb-like tool used to straighten the folds of woven cloth. During their argument, one of the women fell into the pond and drowned. The two fires are believed to represent the women, continuing their conflict even after death.

The name Osabi was recorded by folklorist Kunio Yanagita in Yokai Meii, included in Yokai Dangi, drawing on the account Nobeoka Zatsudan. Yanagita also mentioned a similar mysterious fire from Nagoya known as Kantarōbi.

Kusakaribi

Tradition: Japanese Mythology
Alternative Names: –
Category: Flame


The Myth

Kusakaribi, meaning Grass-Cutting Fire, is a mysterious supernatural flame from the Himeji region of Japan. It appears unexpectedly along roads at night, sometimes emerging as a single flame before multiplying into several fires that twist and intertwine with one another. These strange lights vanish as suddenly as they appear, leaving travellers unsettled by the unexplained spectacle.

At the beginning of the Genbun era (1736–1741), during the rainy season in May, a man named Hanshichi from Sayo Village was staying in Himeji. When his business failed to progress as he had hoped, he decided one evening to visit an acquaintance in Kamata Village. As he travelled through intermittent rain, darkness fell before he reached his destination. Suddenly, a flame burst forth from the middle of the road. As Hanshichi stopped to watch, another appeared, and the two fires twisted and tangled together before abruptly disappearing. After a short while, another flame appeared and vanished in the same mysterious fashion.

Uneasy after witnessing the strange lights, Hanshichi continued his journey and eventually reached his acquaintance’s home. When he described what he had seen, his host explained that the fire had been witnessed on other occasions and was known as the Kusakaribi. According to local legend, two boys who worked cutting grass had once quarrelled and killed each other with their sickles. Their violent deaths supposedly left behind a supernatural presence that continued to appear as a demonic fire along the road. The account was reportedly based on a story that the author, Haruna Tadanari, heard directly from Hanshichi himself.

Aburakae

Tradition: Japanese Mythology
Alternative Names: Morubi, Moribi
Category: Flame


The Myth

Aburakae, meaning Oil Return, is a mysterious supernatural fire associated with Konyo in Itami City, Hyogo Prefecture, Japan. It appears on dark nights in early summer and on cold winter nights, particularly around Konyo Pond. The strange flame is known for its peculiar sounds and its unusual journey through the surrounding landscape.

The Aburakae is said to emerge from the grave of Senso, located south of Konyo Pond, before travelling along the banks of Konyo Pond and Mizugaike Pond. It then follows the Tenjin River toward Nakayama-dera Temple. As it moves, the fire flashes with a repeated “pa-pa-pa-pa” sound, accompanied by a voice calling “ocha-ocha-ocha-ocha.” It advances rapidly without turning back, producing a further sound described as “tobo-tobo-tobo-tobo.”

The true nature of the Aburakae remains uncertain, and several explanations have been offered for its appearance. One tradition claims that it is the restless soul of someone who stole oil from Nakayama-dera Temple and now returns as a supernatural flame. Other accounts identify it as a fox wedding taking place on the northern bank of Konyo Pond, or as a fire kindled by a wolf near Senso’s grave. These different explanations surround the Aburakae with mystery, linking its strange journey to stolen oil, supernatural gatherings, and animals associated with the uncanny.

Morubi

Tradition: Japanese Mythology
Alternative Names: Morubi, Moribi
Category: Flame


The Myth

The Morubi is a terrifying supernatural fire from Goshogawara City in Aomori Prefecture, Japan. It appears as a bright blue flame, particularly on rainy nights in places where people have drowned or hanged themselves. Its body is strangely shaped: the section from its head to its torso is thicker than a human finger, while the parts resembling legs hang loosely beneath it. Floating in the air, this eerie fire is regarded as one of the most frightening supernatural beings.

The Morubi is known to follow people who speak ill of it. Even when struck and shattered into pieces, it does not necessarily stop pursuing its victim, making it difficult to escape once it has taken an interest in someone. Its persistence and association with places of tragic death have earned it a fearsome reputation among local supernatural legends.

Those who encounter a Morubi are advised to chant Buddhist prayers or seek refuge inside a room illuminated by a light. These precautions are believed to offer protection from the relentless blue flame, which may otherwise continue following its chosen victim.

Kangoro-bi

Tradition / Region: Japanese Mythology
Alternate Names: Kantarō Fire, Kangoro
Category: Flame


The Myth

Kangoro-bi is a mysterious fire from Inuyama City, Aichi Prefecture, and other areas.

In Hashizume, Inuyama City, a farmer named Kangoro once lived with his elderly mother. Kangoro was eighteen years old, dutiful, honest, and known for his hard work.

One summer, a long drought caused the water in Kangoro’s rice paddy to dry up, while a neighboring rice paddy still had some water. Before dawn, Kangoro secretly cut down the embankment and diverted the water into his own rice paddy.

When the villagers discovered what he had done, they surrounded him with murderous intent. Kangoro was unable to escape and was beaten to death.

His elderly mother searched for her missing son, but the villagers refused to tell her what had happened. Understanding the situation, she stopped eating and died while continuously calling out Kangoro’s name.

From then on, every summer night, two shadowy flames wandered over the rice fields of Hashizume. For the next 400 years, the Aoki River also flooded many times, causing suffering to the villagers. The river finally calmed when Abbot Taiyo of Inuyama Tokuju Temple prayed for the spirits of Kangoro and his mother.

In Yatsurugi-cho, Iwakura City, the Kangoro fire is said to be the hand lamp of a mother searching for her son Kangoro, who went missing while catching fireflies. It is a bluish-red bare flame that can be seen at any time of year, but was said to be particularly common during the rice-planting season.

Onibi

Tradition: Japanese Mythology
Alternative Names: Ghost Fire, Onibi
Category: Flame


The Myth

Onibi, meaning ghost fire, is a mysterious supernatural flame said to appear in various regions of Japan. It is most often described as a blue fire, sometimes resembling a burning torch, although accounts also describe flames of other colours. These strange lights appear without an ordinary source and are associated with spirits and the lingering presence of the dead.

According to the Wakan Sansai Zue, which cites the Chinese Bencao Gangmu, onibi are formed from the blood of fallen soldiers or cattle and horses that seeps into the earth and transforms over time. This account distinguishes them from will-o’-the-wisps and shadow fires, which are also described as transformations of spirits. Onibi are said to gather together and separate as they approach people, absorbing their life force. However, they can reportedly be made to disappear by producing a sound, such as striking them with a horse’s stirrups.

The name onibi is also used more broadly for mysterious flames of uncertain origin. Depending on the account, it may refer to foxfire, fires born from the resentment of the dead, or other unexplained supernatural lights. These varying descriptions make onibi a broad category of eerie flames associated with spirits, death, and mysterious occurrences.

Nojukubi

Tradition: Japanese Mythology
Alternative Names: –
Category: Flame


The Myth

Nojukubi is a mysterious supernatural fire that appears along country roads, highways, and in the mountains of Japan. It manifests in places where no people are present, burning briefly before suddenly going out, only to appear again somewhere nearby. Unlike ordinary fires, it seems to arise without any visible cause, illuminating lonely and deserted places before vanishing into the darkness.

The Nojukubi is distinguished from foxfire and other natural-looking mysterious flames. Its appearances are unpredictable, and it is sometimes accompanied by strange sounds, including the noise of people talking excitedly or singing. These unexplained voices, heard alongside the flickering flames, give the phenomenon an eerie quality, as though an unseen gathering were taking place in the wilderness.

Yōsei

Tradition: Japanese Mythology
Alternative Names: 妖精, Fairy
Category: Fairy


The Myth

Yōsei is the Japanese term used for fairy-like supernatural beings, generally referring to small and mysterious spirits. In Japanese tradition, the word can describe beings resembling the fairies of Western folklore, while some older beliefs associate such creatures with supernatural powers that could affect the living and the dead.

One old belief from Iwate Prefecture held that yōsei could resurrect the dead, giving them an unusual and potentially frightening power over the boundary between life and death. Another tradition speaks of the small fairy-like people of Mount Hōrai, who were said to know nothing of great evil. Because they were untouched by such wickedness, their hearts never grew old, portraying them as beings of innocence and supernatural purity.

Japanese and neighboring traditions also contain several other small fairy-like peoples. Ainu folklore tells of the Koro-pok-guru, a race of small people, while Okinawan tradition has the Kijimunā, tree-dwelling spirits associated with banyan trees. Together, these traditions provide the wider Japanese folklore context in which yōsei can be understood as small, mysterious supernatural beings existing between the familiar human world and the realm of spirits.
