The Myth

The Arima Bake-neko is one of Japan’s most famous monster cat legends. The story takes place at the Edo residence of the Arima clan during the rule of Lord Arima Yoriyuki.

During a banquet, a wild dog burst into the palace while chasing a kitten. As the dog lunged toward the lord, a lady-in-waiting named Otaki struck it dead with an iron ladle, saving his life. When the lord offered her a reward, she asked only that the frightened kitten be spared. Impressed by her courage and kindness, the lord took her as his concubine.

Otaki’s rise provoked the jealousy of the other women in the household, especially the head lady-in-waiting, Iwanami, who relentlessly tormented her. Unable to endure the abuse any longer, Otaki took her own life.

The kitten she had rescued, now named Tama, licked Otaki’s spilled blood and transformed into a monstrous cat. Seeking revenge, it burst into the palace and killed Iwanami by tearing out her throat. Afterward, the women responsible for tormenting Otaki died one after another under mysterious circumstances.

The monster’s vengeance grew ever more savage. It murdered the pregnant concubine Otoyo, ripping open her body and killing both her unborn child and her maid. It even attacked Lord Yoriyuki himself while he walked in the garden, but the guard Yamamura Tenzen struck the creature between the eyes with his sword, forcing it to flee.

When Tenzen returned home, he discovered that his elderly mother bore the same wound. He realized the monster cat had already killed and devoured her, assuming her appearance to hide among the living.

Joining forces with the former sumo wrestler Onogawa Kisaburō, Tenzen hunted the creature to the Arima residence’s great fire watchtower, where it had made its lair. There the monster revealed its true form, but together the two men defeated and killed it, finally ending the cat’s bloody revenge.

Kasha

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.

Nuegyo

The Myth

Nuegyo is a strange and unsettling fish said to appear in the seas off the coast of Japan. Those who encountered it did not recognize it as any known creature of the ocean, and even experienced fishermen were unable to name it.

The Nuegyo is said to be about the length of a man’s forearm. Its skin is rough, like that of a shark, while its head resembles that of a cat. Atop its head rests a hard, bowl-shaped mass, like stone. Its nose and mouth are also catlike, and from both sides of its jaw protrude sharp, bone-like spines several inches long. A thin spine rises from the top of its head, giving it an even more unnatural appearance.

Its body is shaped somewhat like that of a gurnard, but its fins are long and soft, extending all the way toward the tail. These fins are wide and flexible, like the wings of a bat. When spread open, they form a fan-like shape. It is said that the Nuegyo can use these fins as wings, rising above the surface of the sea and gliding through the air.

Because of its bizarre combination of features—part fish, part beast, and capable of flight—people began to call it Nuegyo, likening it to the legendary Nue, a creature made of mismatched forms. Whether it truly flies or merely skims the waves is unknown, but the Nuegyo is remembered as a sea being that does not fully belong to water or sky, and whose appearance defies ordinary understanding.
