Unlike the dragonflies depicted in European folklore, the dragonflies in Japanese mythology, particularly in the context of the mermaid legend, appear quite different from what one might expect in Disney animated films.
The ningyo (translated literally as “human fish”) in Japan is often portrayed as a creature with a human-like upper body but resembling a smaller fish below. If you’re having difficulty visualizing what a ningyo looks like, the video below will help clarify or perhaps add to your confusion tonight.
However, no one can be certain how exactly this mermaid was preserved. Therefore, in February of last year, a group of five researchers from Kurashiki University of Science and the Arts in Okayama began an investigation to determine the true identity of this specimen. They employed various modern verification methods, such as X-ray imaging, CT scans, DNA analysis, and carbon dating.

After a year of research, just yesterday, the team announced their findings. Unfortunately for those enchanted by the folklore, it turns out that the specimen is not an actual mermaid. The researchers noted that they identified that the specimen was made from a unique structure consisting of a fish-like body, as the “ningyo” measures only 30 cm and lacks limbs, resembling a living fish or a dried fish.
Furthermore, the investigation revealed that this specimen was crafted from what appears to be a type of high-quality cloth or a material similar to silk. It features distinct anatomical points including arms, hands, and even facial features. The upper section also contained parts made from fabric, layered within a thin membrane, and then encased in fugu skin (a type of blowfish). The head was also made from fabric and stuffed with an indeterminate animal fur.
While the body and limbs were found to resemble those of a croaker fish, the physical specimen was discovered to have been found in the mouth of a citizen around the year 1740, which was also part of a cooking experiment. Researchers, after examining a sample, calculated that the mermaid specimen might actually date back to the late 1800s.


Scientists have confirmed that this is indeed a mummified specimen.
However, the administrators involved are not disheartened by the discovery. In a statement after the researchers announced their findings, Chief Hiroyoshi Kuida noted: “I think that, because of the story itself, many people were drawn to see the ningyo when it was displayed and prayed when they were here. And I think we will continue to do so.”
“Now that we know it is made from living creatures, we will continue to take good care of it and ensure its safety,” he added.
Fortunately, ningyo does not carry any specific religious significance in Japanese Buddhism. Therefore, the unveiling of this specimen at Enjuin is unlikely to cause any disruption or diminish the number of visitors to this site.
