Ken’etsu appears in the humorous illustrated work Mubō Sanzai Zue. Rather than a fearsome monster, it belongs to the strange and satirical creatures sometimes described in Edo-period folklore and parody bestiaries.
It is said that Ken’etsu was born from mud, and its body bears the color of damp earth — a bluish-black tone like wet soil. Like birds whose feathers resemble leaves or fish whose scales mirror the ripples of water, Ken’etsu’s appearance reflects the place of its origin.
The creature is described as a dog that vomits everything it eats, never needing to defecate. It drinks enormous quantities of water, and as it does so, its complexion shifts and changes. From this image comes an old saying about a dog that “vomits and changes color.”
In some depictions, Ken’etsu is shown in a more humanlike form — a figure crawling on all fours, retching repeatedly, illustrating the comparison between the creature and a drunken person who has made themselves sick. Because of this, the name “Dog’s Delight” also came to be used as a humorous expression for a drunkard who vomits and grows pale, likened to a dog contentedly eating its own sick.
Thus Ken’etsu lives on less as a terrifying spirit and more as a grotesque and comic yokai, a muddy creature of excess, sickness, and satire.
In the folklore of Okinawa, there is said to be a mysterious yokai known as Innu, a name that simply means “dog” in the local language. The creature is remembered mainly through brief written references rather than long stories, but those mentions describe it as something uncanny and supernatural.
According to one early account, the Innu is a strange being that wanders about while dealing with fire. Some traditions say it roams the night devouring flames, moving from place to place as if feeding on burning light. Other interpretations describe it not as eating fire, but as carrying it, walking through the darkness with flames in its presence like a living torch.
Though little detail survives about its appearance or behavior beyond this, the Innu is remembered as a roaming, fire-associated dog spirit, moving silently through the night in the villages of Okinawa, its presence tied to mysterious lights and wandering flames.

The Myth
During the Kanpō era in the mid-18th century, a strange event was said to have occurred in Tojinmachi in Fukuoka. A household dog gave birth to a litter in which one of the newborns was unlike the others.
This puppy was described as having the body of a normal dog but a head shaped like the thick, curved beak of a crow. The unnatural appearance shocked those who saw it, and word spread quickly through the town. Such abnormal births were often regarded as signs or warnings, and people treated the creature with a mixture of fear and curiosity.
Despite its unusual form, the puppy was cared for. It was fed rice and fish like any other household animal, but it survived only a short time before dying.
The incident was later recorded in illustrated works such as Kaikaidan Ekotoba. Although the scroll itself did not give the creature a specific name, later sources referred to it simply as “the monster born from a dog.” In modern references, it is often called the Beaked Dog of Tojinmachi, remembered as one of the strange births and ominous wonders noted in Edo-period tales.

The Myth
Yatsufusa was a remarkable dog said to have been born in a village beyond Toyama in Awa Province. When he was only a week old, his mother was killed by a wolf, and the pup seemed certain to die. But a raccoon dog, appearing as a drifting will-o’-the-wisp, came and nursed him with milk. The pup survived and grew into an unusually large, powerful dog with sharp eyes and a noble bearing.
Word of this strange animal reached Satomi Yoshizane, lord of Awa, who summoned the dog to his court. The dog’s black-and-white coat bore eight peony-like markings, and so he was named Yatsufusa, “Eight Tufts.” He became the Satomi family’s cherished pet and grew deeply attached to Yoshizane’s daughter, Princess Fusehime, never leaving her side.
Years later, famine weakened the Satomi lands, and the enemy lord Anzai Kagetsura invaded. The castle stood on the brink of collapse. In desperation, Yoshizane jokingly told the starving Yatsufusa that if he killed the enemy general, he would reward him with Fusehime’s hand in marriage.
That night, Yatsufusa returned carrying the severed head of Kagetsura. The promise, made in jest, had been fulfilled in earnest. Yoshizane rewarded the dog with rich food and servants, but Yatsufusa refused all comforts, remaining beside the head as though waiting for the promised reward.
When Yoshizane realized the dog’s attachment to his daughter, he tried to drive Yatsufusa away. The dog broke loose and forced his way into the mansion, and Yoshizane prepared to kill him. Fusehime stopped her father, reminding him that a promise once spoken must be honored. Reluctantly, Yoshizane allowed her to leave with the dog.
Yatsufusa carried Fusehime into the mountains, where they lived together in a cave. She brought with her a copy of the Lotus Sutra and spent her days reciting it. Yatsufusa listened, growing calm and devoted, and never violated her. A hermit’s messenger later revealed that the dog’s true nature was bound to past grudges and karmic ties, but that the sutra’s power had begun to free him.
Through the merit of the sacred text, Fusehime conceived eight spiritual children. She later resolved that she and the dog should end their suffering and be reborn in better form. As Yatsufusa prepared to follow her into the water, a shot rang out. A warrior attempting to rescue the princess fired, and the bullet struck both dog and girl.
Fusehime died after proving her purity, and the rosary she carried burst apart, sending eight sacred beads flying into the world. From these beads would arise the Eight Dog Warriors, heroes bound by virtue.
After her death, Fusehime’s spirit was sometimes seen riding Yatsufusa, guiding the warriors who carried the beads and watching over their destinies.

The Myth
Sunekosu is a strange creature said to appear in Oda County of Okayama Prefecture. It is most often encountered on rainy nights, when the roads are quiet and visibility is poor.
Those walking alone sometimes feel something brush suddenly against their legs. Looking down, they may glimpse the shape of a small animal like a dog slipping past them in the darkness. It moves silently and quickly, weaving between the legs of travelers before vanishing into the night.
The creature does not attack, but its sudden contact startles those who encounter it. Afterward, nothing can be seen or heard, leaving only the uneasy feeling that something unseen passed close by in the rain.

The Myth
Zobutsu Daijoou is the highest-ranking of the twelve great demon kings described in a religious account of the demon realm. She is said to possess power one hundred times greater than that of an average god and is considered so terrifying that even powerful spiritual masters warned against approaching her. She has a white face, thin black eyebrows, yellow lips, and stands about three feet tall. Her hair rises two feet upward, bends backward, and divides into three sections that fall to her waist. She was said to have come into being when the accumulated shadows at the creation of the world condensed into evil energy.
Among the hundreds of demon leaders said to inhabit the demon realm, twelve hold the highest rank, and Zobutsu Daijoou stands above them all. Each of these demon kings rules a separate domain with their own followers and may bring disaster upon the human world. Alongside her in special distinction is the Queen of the Bottomless Sea, and together they are set apart from the rest.
On the night of July 19, 1880, a procession of these demon kings was said to pass across the sky. Their names were identified as they appeared, with Zobutsu Daijoou recognized as the foremost among them.

The Myth
The Kasha is a cat-like yokai associated with death and the punishment of wrongdoers. It is said to carry away the corpses of those who committed crimes, and is often depicted grasping a body while connected to a flaming chariot or fire.
The Kasha appears when a person who has committed wrongdoing dies. It takes the corpse and carries it away, acting as an agent of karmic consequence rather than human judgment. It is portrayed as a cat-like being that may stand upright and seize the body, sometimes shown with a chariot of fire. Images of the Kasha appear in works such as death scrolls and mandalas, where it is shown taking the dead away. Its form varies by region, sometimes more monstrous and sometimes more cat-like, but it is consistently associated with the removal of sinful corpses and the inevitability of moral consequence.
Yama-Otoroshi is a yokai said to inhabit Mount Tsurugi in the Tateyama mountain range. It is described as resembling an ogre with a red face and body and lacking iron bars. It was believed to wait on rocky outcrops and attack climbers.
It was said that before 1907, climbers failed to reach the summit of Mount Tsurugi because the Yama-Otoroshi waited on the rocks, seized them by the collar, and threw them to their deaths. After the Meiji period, the being was said to descend from the mountain and take up residence at temple gates such as Zenkoji Temple. There it grabbed non-believers by the collar and stopped them from passing through. In this form, it was also called simply Otoroshi. An illustration shows the red-faced, two-horned ogre throwing away a climber.

The Myth
Torakoishi is a legendary stone associated with Tiger Gozen, a courtesan of Oiso-juku known from Soga Monogatari as the lover of Soga Juro Sukenari. A stone kept at Entaiji Temple in Oiso is said to have been given through the power of Benzaiten, and is believed to possess protective and miraculous qualities. It became known as a local curiosity and was publicly shown at certain times.
According to tradition, the stone was connected to a girl born on the Day of the Tiger who grew as she aged through Benzaiten’s power. When assassins sent by Kudo Suketsune attacked, the stone took the form of Soga Juro, blocking the arrows and saving them. The stone at Entaiji Temple is said to ward off evil, grant children, and fulfill wishes when touched, and it was displayed to the public each May. During the Edo period it was known as a roadside attraction and was said that only handsome men could lift it. An 1859 print by Utagawa Yoshikazu depicts the stone with tiger legs and a tail startling passersby, in the style of local monster caricatures.

The Myth
Kubiore Neushi is remembered as a stone cow statue connected to Takimiya Hachiman Shrine in Sanuki.
In the year 888, the land of Sanuki suffered a terrible drought. Rivers dried up, rice fields withered, and the villagers feared famine. Sugawara no Michizane, then governor of the province, fasted, purified himself, and climbed Mount Shiroyama to pray for rain.
At first, the heavens sent firestones and then pebbles, which frightened the people, but Michizane continued his devotions. On the final night of his ritual, the god of Mount Shiroyama appeared to him in a dream and told him that if he offered even a single drop of water to the heavens, a heavy rain would come.
Michizane threw his ink-soaked brush into the sky. At once, black clouds gathered, thunder rolled, and rain poured over the land. The dying crops revived and the villagers rejoiced. They gathered at Takimiya Hachiman Shrine and danced in celebration.
It is said that the joy of that day was so great that the stone cow statue before the shrine joined the dance. In its enthusiasm, the cow broke its neck and became known as the Sleeping Cow with a Broken Neck. The villagers preserved their celebration as the Takimiya Nembutsu Dance in memory of the rain and the event.
