Ningyo is a spirit of Japanese tradition.
Fish-human whose flesh is said to grant eternal life.
The Ningyo is considered a Japanese mermaid, but is a fish with a human face and was regarded as an omen. According to legend its flesh grants longevity, as told in the legend of Yao Bikuni; the source is the court chronicle Nihon shoki (720).

Appearance
The Ningyo is predominantly a fish with a human face, resembling a mermaid only since the 19th century.
Effect
It appears as an omen; its flesh prolongs life, alienating one from the course of generations.
The key aspects at a glance.
An omen being between court chronicle and folk belief, attested since 720.
Fishermen and coastal communities, for whom a find or catch was seen as an omen.
Scaly fish body with a human face, rarely with arms.
An omen of misfortune or blessing, its flesh prolongs life.
Releasing the catch, burial of stranded animals, its flesh as taboo.
The serpent-bodied Nure-onna is another water being.
The oldest source is the court chronicle Nihon shoki (720): for the year 619 it reports a being from the Gamō River, ‘neither human nor fish’. The Yao Bikuni legend tells of the nun from Wakasa who, through eating Ningyo flesh, ceases to age and outlives everyone.
Ningyo specimens gave rise to Barnum’s ‘Feejee Mermaid’ of 1842. The Enjuin temple example was determined in 2022 to be an elaborate construction of cloth and fish parts, yet it had been venerated for centuries. In religious studies the Ningyo is read as a sign, not as an adversary.
Captured Ningyo were released, stranded animals were buried, and their flesh was regarded as taboo. Protection was offered by amulets, salt and holy water.
Does Ningyo flesh grant immortality?
A narrative motif: the legend grants longevity, but the tale also shows it as a burden.
Difference from the mermaid?
Predominantly a fish with a human face, without a woman’s upper body.

As a Japanese mermaid, the Ningyo remains a being of its own: a silent omen whose flesh, in the legend of Yao Bikuni, shows that eternal life without community becomes a punishment.
