The Myth

During the Meiji era, an inn in Hirakawa-chō, Kojimachi Ward, Tokyo, became notorious for strange occurrences in its eight-mat room on the second floor. According to an 1898 report in the Miyako Shimbun, anyone who stayed there was said to experience terrifying nightmares in a state somewhere between dreaming and waking.

One guest dreamed that a giant was strangling him. Another experienced a beautiful young woman tormenting him. Two explorers who had returned from overseas decided to stay in the room themselves in order to discover the truth behind the phenomenon.

During the night, one of the explorers awoke from a nightmare in which a giant was strangling him. When he asked his companion what was happening, the other revealed that he too had experienced a strange dream.

His nightmare, however, concerned something much stranger: beef.

In the dream, an enormous piece of beef suddenly descended from the ceiling beams. As someone who considered himself a great eater of beef and horse meat, he initially believed that disposing of it should have been easy, whether by boiling or roasting it. Yet within the dream he found himself completely unable to get rid of the enormous mass of meat.

He tried various methods, but nothing worked. Eventually he became overwhelmed and helpless, suffering so intensely that he awoke covered in sweat.

At the same time, his companion was also suffering from his own nightmare about the giant monster.

The report offered several possible explanations for the strange experiences. Some suggested that animals such as martens living in the attic might emit a form of “animal electricity” that caused the disturbing dreams. Another explanation was more psychological: the first person to experience a nightmare in the room may have told others about it, causing subsequent guests to enter the room already frightened and consequently experience similar nightmares.

The Ō-gyūnikukai is therefore less a conventional monster than a strange Meiji-era account of a supernatural nightmare, in which an enormous piece of beef itself becomes the source of terror.

The Myth

Long ago, in Shinano Province, there lived a wicked and unfaithful old woman in Chiisagata District.

One day, while she was drying a hand towel beneath the eaves of her house, a mysterious cow suddenly appeared. The animal caught the towel upon its horns and immediately ran away.

The old woman chased after it, determined to retrieve her towel. However, the cow continued running until she eventually found herself at the dining hall of Zenkoji Temple. By the time she arrived, the sun had set and darkness had fallen. The mysterious cow had disappeared.

Then something miraculous happened.

The Buddha of Zenkoji Temple suddenly emitted a radiant light, illuminating the trail of drool that the cow had left behind. When the old woman looked closely, she saw that the shining trail formed words. The message told her not to think of the incident as merely the work of a cow, but to understand that her own heart had guided her toward the path.

The old woman was deeply moved by the revelation. She immediately became devoted to Buddhism and spent the night before the Buddha chanting sutras.

When she returned home the following day, she visited a nearby Kannon hall. There, beside the statue of Kannon, she discovered the hand towel that the mysterious cow had taken.

She realized that the cow had actually been an incarnation of Kannon.

Her faith in the Buddha of Zenkoji consequently became even stronger, and she eventually attained rebirth in paradise.

According to the tradition, the Kannon who appeared in the form of the cow was the Nunobiki Kannon, whose statue is preserved at Nunobikiyama Shakusonji Temple in Komoro.

The story became the origin of the Japanese expression meaning to be “led to Zenkoji Temple by a cow”—being unexpectedly guided toward something good by an event whose purpose was not initially understood.

From the Edo period through the Meiji period, prints depicting the miraculous cow leading the old woman to Zenkoji Temple were repeatedly produced and sold around the temple.

The Myth

Namedara-ushi is said to be the master of Aoike Pond in Gunmura, Masuzu County, in present-day Fujieda City, Shizuoka Prefecture. The legend is recorded in the Suruga no Kuni Zasshi (Miscellaneous Records of Suruga Province).

It was said that whenever Namedara-ushi howled, rain would soon follow. At the bottom of Aoike Pond were believed to be seven water holes from which clear water continually gushed forth. Even during severe droughts, the water level of the pond was said never to decrease.

During times of drought, local farmers performed a rain-making ritual centered around the creature. They constructed a large cow from straw and placed it into the water holes while beating gongs and drums and dancing. According to the tradition, rain would always arrive within three days of performing the ritual.

The connection between the name and the ritual suggests that the “ushi” in Namedara-ushi means “cow.” The creature itself is therefore closely associated with the sacred waters of Aoike Pond and the ritual practices used to bring rain.

The Myth

Mōnen is a yokai depicted in Kikuya Kinji’s Shinshin Obake Nobanashi (New Ghost Tales), published in 1886.

It appears as a cow that has transformed into a ghost. The creature wears a kimono decorated with a wheel pattern and holds its hooves out in front of its body in the manner of a traditional Japanese ghost.

The name Mōnen is a wordplay on mōnen, meaning “delusion,” and mō, the sound associated with a cow’s moo.
