Lurking the halls of Buddhist temples and museums across Japan are a host of monster mummies — the preserved remains of demons, mermaids, kappa, tengu, raijū, and even human monks. Here are a few remarkable specimens for the adventurous and brave at heart.
- Demon mummies
It might seem odd that Buddhist temples in Japan house the occasional stray mummified demon (oni), but then again it probably makes sense to keep them off the streets and under the watchful eye of a priest.
Zengyōji (善行寺) temple in the city of Kanazawa (Ishikawa prefecture) is home to the mummified head of a three-faced demon. Legend has it that a resident priest discovered the mummy in a temple storage chamber in the early 18th century. Imagine his surprise.

Nobody knows where the demon head came from, nor how or why it ended up in storage.
The mummified head has two overlapping faces up front, with another one (resembling that of a kappa) situated in back. The temple puts the head on public display each year around the spring equinox.
Another mysterious demon mummy can be found at Daijōin temple in the town of Usa (Oita prefecture).
The mummy is said to have once been the treasured heirloom of a noble family. But after suffering some sort of misfortune, the family was forced to get rid of it.
The demon mummy changed owners several times before ending up in the hands of a Daijōin temple parishioner in 1925. After the parishioner fell extremely ill, the mummy was suspected of being cursed.
The parishioner quickly recovered from his illness after the mummy was placed in the care of the temple. It has remained there ever since. Today the enshrined demon mummy of Daijōin temple is revered as a sacred object.
A much smaller mummy — said to be that of a baby demon — was once in the possession of Rakanji Temple at Yabakei (Oita prefecture).
Unfortunately, the treasured mummy was destroyed in a fire in 1943.

- Mermaid mummies
In Edo-period Japan — particularly in the 18th and 19th centuries — mermaid mummies were a common sight at popular sideshow carnivals called misemono. Over time, the practice of mermaid mummification blossomed into an art form as fishermen perfected techniques for stitching the heads and upper bodies of monkeys onto the bodies of fish.
The mummy pictured below is a prime example of a carnival mermaid. It appears to consists of fish and other animal parts held together with string and paper.
The mummified creature was obtained by Jan Cock Blomhoff while serving as director of Dejima, the Dutch trading colony at Nagasaki harbor from 1817 to 1824. It now resides at the National Museum of Ethnology in Leiden.
Another old mermaid mummy exhibited at a museum in Tokyo several years ago appears to belong to the founder of the Harano Agricultural Museum.
The mummy’s origin is unknown, but the collector says it was found in a wooden box that contained passages from a Buddhist sutra written in Sanskrit. Also in the box was a photograph of the mermaid and a note claiming it belonged to a man from Wakayama prefecture.

- Kappa mummies
Like the mermaid mummies, many kappa (river imp) mummies are thought to have been crafted by Edo-period artists using parts of animals ranging from monkeys and owls to stingrays.
This mummified kappa, which now resides in a Dutch museum, appears to consist of various animal parts put together in a seamless whole. It is believed to have been created for the purpose of carnival entertainment in the Edo period.
Another mummified kappa can be found at Zuiryūji temple in Osaka.

The 70-centimeter long humanoid purportedly dates back to 1682.
Another notable kappa mummy can be seen in a seemingly unlikely place — at a sake brewery in the town of Imari (Saga prefecture).
According to a company brochure, the mummified kappa was discovered inside a wooden box that carpenters found hidden in the ceiling when replacing the roof over 50 years ago.
Reckoning the creature was an old curiosity their ancestors had passed down for generations, the company owners built a small altar and enshrined the kappa mummy as a river god.

With a limited scientific understanding of the sky above, the common person in Edo-period Japan looked upward with great awe and mystery. Supernatural creatures called raijū (雷獣) — lit. “thunder beast” — were believed to inhabit rain clouds and occasionally fall to earth during lightning strikes.
The earliest known written records of the raijū date as far back as the late 18th century, though the creature appears to borrow characteristics from the nue — a cloud-dwelling, illness-inducing chimera first described in The Tale of the Heike, a 12th-century historical epic.
Details about the raijū’s appearance vary. Some Edo-period documents claim the raijū resembled a squirrel, cat or weasel, while others describe it as being shaped more like a crab or seahorse.
However, most descriptions agree that the raijū had webbed fingers, sharp claws, and long fangs that, by some accounts, could shoot lightning. The beast also sometimes appeared with six legs and/or three tails, suggesting the ability to shape-shift.
One illustrated document tells of a raijū that fell from the sky during a violent storm on the night of June 15, 1796 in Higo-kuni (present-day Kumamoto prefecture).
Here, the raijū is described as a crab-like creature with a coat of black fur measuring about 11 centimeters (4 inches) thick.
Another notorious encounter took place in the Tsukiji area of Edo on August 17, 1823. Two versions of the incident offer different descriptions of the beast.
One document depicts the raijū as being the size of a cat or weasel, with one big bulging eye and a single long horn, like that of a bull or rhino, projecting forward from the top of its head.
In the other account, the raijū has a more roundish look and lacks the pointy horn.
In Volume 2 of Kasshi Yawa (”Tales of the Night of the Rat”), a series of essays depicting ordinary life in Edo, author Matsuura Seizan writes that it was not uncommon for cat-like creatures to fall from the sky during thunderstorms. The volume includes the story of a family who boiled and ate one such creature after it crashed down onto their roof.
Given the frequency of raijū sightings, it should come as no surprise that a few mummies have turned up.
In the 1960s, Yūzanji temple in Iwate prefecture received a raijū mummy as a gift from a parishioner. The origin of the mummy, as well as how the parishioner obtained it, is a mystery.
The mummy looks like that of a cat at first glance, but the legs are rather long and the skull has no visible eye sockets.

- Tengu mummy
Another legendary supernatural sky creature is the tengu, a dangerous demon often depicted in art as being part human and part bird. The Hachinohe Museum (Aomori prefecture) in northern Japan is home to a tengu mummy, which is said to have once belonged to Nambu Nobuyori, a Nambu clan leader who ruled the Hachinohe domain in the mid-18th century.
The mummy, which appears to have a humanoid head and the feathers and feet of a bird, is believed to have originated in the town of Nobeoka (Miyazaki prefecture) in southern Japan. Theories suggest the tengu mummy made its way north after being passed around between members of Japan’s ruling samurai families, some of whom were deeply interested in collecting and trading these curiosities.

- Self-mummified monks
A few Buddhist temples in northern Japan are home to “living mummies” known as sokushinbutsu (即身仏). The preserved bodies are purportedly those of ascetic monks who willingly mummified themselves in the quest for nirvana.

To become a living mummy, monks had to undergo a long and grueling three-step process.
Step 1: For 1,000 days, the monks would eat a special diet of nuts and seeds, and engage in rigorous physical training to strip the body of fat.
Step 2: For another 1,000 days, they would eat only bark and roots in gradually diminishing amounts. Toward the end, they would start drinking tea made from the sap of the urushi tree, a poisonous substance normally used to make Japanese lacquer bowls, which caused further loss of bodily fluid. The tea was brewed with water from a sacred spring at Mt. Yudono, which is now known to contain a high level of arsenic. The concoction created a germ-free environment within the body and helped preserve whatever meat was left on the bone.
Step 3: Finally, the monks would retreat to a cramped underground chamber connected to the surface by a tiny bamboo air pipe. There, they would meditate until dying, at which point they were sealed in their tomb. After 1,000 days, they were dug up and cleaned. If the body remained well-preserved, the monk was deemed a living mummy.
Unfortunately, most who attempted self-mummification were unsuccessful, but the few who succeeded achieved Buddha status and were enshrined at temples. As many as two dozen of these living mummies are in the care of temples in northern Honshu.
The Japanese government outlawed the practice of self-mummification in the late 19th century.
