The Myth

Shokera is a strange creature known from monster scrolls such as the Hyakkai Zukan and the Gazu Hyakki Yagyō. In some depictions it appears as a pale, dog-like being that walks on two legs, while in others it is shown as an oni-like figure peering down into houses through skylights.

Its presence is tied to the night of Kōshin, a day that comes once every sixty days. On this night, people believed that the sanshi—three spirit-insects living inside the human body—would leave their host while they slept and ascend to Heaven to report the person’s sins to the Heavenly Emperor. If the report was unfavorable, the Emperor would shorten that person’s lifespan.

To prevent this, people held Kōshin-machi, gatherings where they stayed awake all night in strict discipline so the insects could not escape.

It was said that if someone fell asleep on this night, the demon Shokera would appear. The creature would bring sickness, misfortune, and a shortening of life to those who failed to remain vigilant. To protect themselves, people sometimes recited special chants meant to ward Shokera away until dawn.

Thus the Shokera became a warning figure: a watcher in the darkness, said to visit the careless, and a reminder that on certain nights, sleep itself could invite disaster.

Zobutsu Daijoou

by

Tradition / Region: Japanese religious folklore
Alternate Names: Kuriekisu, Great Queen of Creation
Category: Demon

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.

Kidoku

by

Tradition / Region: Japanese Mythology
Alternate Names: Oni-doku
Category: Mountain dweller, Demon

The Myth

On the thirteenth day of the eighth month in the second year of Kan’en (1749), a strange and terrifying event took place in Soma County of Hitachi Province.

Atop Mount Masakado stood an ancient pine tree. It was said to have grown there since the days of Taira no Masakado, its roots gripping the mountain for generations. But that year, long and relentless rains soaked the land. The mountain soil eroded, and floodwaters rushed down its slopes, exposing the roots of the old pine. Then a fierce wind arose and toppled the great tree from its base.

When the pine fell, something was revealed beneath its roots.

Buried in the earth lay a monstrous being—what people called a “Kidoku,” a Demon Slayer, though no one knew its true nature. As the rain beat down upon it, the creature awoke and began to scream.

Its cries echoed across the castle town below. The sound was so dreadful that men, women, and children alike were seized with terror. Some collapsed where they stood. Others fled indoors, covering their ears. The wailing did not cease.

The castle’s commander gathered a rifle squad and marched to the mountain. The creature, fully exposed now, writhed and shrieked beneath the fallen pine. It was immense—said to be the size of eight tatami mats laid side by side.

Those who saw it described a form like a monstrous ogre mixed with a crab. Its eyes were round and bowl-like, shining with an eerie light. The top of its head was sunken inward. Crimson hair, stiff and sharp like palm leaves, bristled from its scalp, and beneath its chin grew spiky strands like thorns. Its teeth were bared in rage.

The riflemen fired again and again. After several shots, the monster finally fell silent.

Thus the Kidoku was slain, and the mountain returned to stillness. But people long remembered the day when the ancient pine fell, and a screaming demon rose from the earth beneath its roots.

Asukokoko

by

Tradition / Region: Japanese Mythology
Alternate Names: —
Category: Yokai, Demon

The Myth

Asukokoko appears in an old depiction of the Night Parade of One Hundred Demons. It is not shown as a single body, but as a mass of many monster faces and grasping hands, all emerging from what looks like a drifting black cloud.

The faces leer and stare in different directions, while the hands reach outward as if the darkness itself were alive. There is no clear center to the creature, no fixed form that can be grasped or confronted.

Its name, Asukokoko, is understood to mean “here and there.” The monster is everywhere at once, scattered and unfixed, as though demons were appearing in many places at the same time.

Thus Asukokoko is not a single being that moves through the world, but a presence that manifests wherever fear gathers—faces and hands rising from darkness, here and there, without warning.
