Ningyo

as the name suggests, is a creature with both human and fish-like features, described in various pieces of Japanese literature.

Though often translated as "mermaid", the term is technically not gender-specific and may include the " mermen". The literal translation "human-fish" has also been applied.

Overview

The earliest records of the ''ningyo'' attested in written Japanese sources are freshwater beings allegedly captured in the 7th century ( §Asuka period), documented later in the '' Nihon Shoki''. But subsequent examples are usually seawater beings.

In later medieval times ( §Kamakura period)), it was held to be a sign of ill omen, and its beaching ( §Omens in Michinoku) was blamed for subsequent bloody battles or calamity.

The notion that eating its flesh imparts longevity is attached to the legend of the ('eight hundred ear oldBuddhist priestess', cf. §Yao Bikuni)

During the Edo period, the ''ningyo'' was made the subject of burlesque ''gesaku'' novels (cf. §Saikaku, 1687 and Santō Kyōden's §''Hakoiri musume'', 1791). There were also preserved ''ningyo'' being manufactured using fish parts ( §Mummies or Feejee mermaids), and illustrated by some scholars of the period (e.g. §Baien gyofu); some such mummies are held by certain temples that have ningyo legend attached to them (cf. §Prince Shōtoku).

The description of the ningyo as having a red cockscomb ( §Shokoku rijindan, and Saikaku) or light red hair ( §Kasshi yawa) corroborates the hypothesis that oarfish sightings led to ningyo lore.

One giant ''ningyo'' was allegedly shot in 1805, even though it was held to be lucky, according to the news circulated in '' kawaraban'' pamphlet form ( #Etchū Province ningyo, aka ''kairai''§Etchū Province ningyo, aka ''kairai'')

Terminology

The Japanese has been glossed in a noted dictionary ('' Kojien'') as a "fabulous creature" which is "half woman, half fish", later revised to "half human (usually woman) and half fish". Hence the term ''ningyo'' includes not just the mermaid but the merman also.

Accordingly, the ''ningyo'' is sometimes referred to by the verbatim translation "human-fish" in English-language scholarship, thus allowing for the gender ambiguity.

The term ''ningyo'' was not explicitly used in the earliest accounts (cf. §Asuka period, year 619) recorded in the '' Nihon shoki'' (720 AD). A later embellished account in
involving Prince Shōtoku claims that the Prince Regent knew the term ''ningyo'', though this is regarded with skepticism. The term ''ningyo'' was likely absent from any of the primary sources used in compiling the ''Shoki'', and nonexistent in the Japanese vocabulary during the Prince's time.

The term ''ningyo'' was also absent in medieval sources describing the Kamakura Period strandings in northern Japan §Omens in Michinoku) considered ominous. For example, a "large fish" washed ashore in the Hōji 1 (1247) according to 13th and 14th century texts. But these were called ''ningyo'' in a 17th-century recompilation.

Zoological hypotheses

The earliest examples (cf. §Asuka period) were caught in fresh waters, and it has been hypothesized they must have actually been giant salamanders.

Another prominent theory is that the misidentification of the ''dugong'' led to mermaid lore, but detractors pointed out that the dugong's range reaches only as far north as Okinawa (formerly the Kingdom of Ryūkyū), and so was not likely to have been seen during premodern times in various locations in Japan where mermaid legend (priestess who ate the mermaid) is known to occur. However, this argument is flawed, since there were other sea mammals of the ''Sirenia'' order, namely Steller's sea cows which were native to the Bering Sea, and could have plausibly wandered into northern Japanese seas. Other sea mammals such as seals and dolphins are also candidates to have been mistaken for human-fish.

An inscribed wooden slat (''mokkan'') containing drawings of ningyo (13th century) suggest the actual animal captured may have been a pinniped, such as a seal (cf. §Ritual offering tablet).

The ichthyologist's hypothesis that the ningyo legend originated from sightings of the red-crested oarfish is bolstered by the lore or reports that the ningyo has red cockscomb ( §Shokoku rijindan) or light red hair ( §Kasshi yawa). This cockscomb also is mentioned in the novel by §Saikaku.

Iconography

Despite the ''ningyo'' being defined as half-woman, half-fish in some modern dictionaries, the ''ningyo'' has been also depicted as having a human female head resting on a fish-like body, as in the well known Japanese woodblock print '' kawaraban'' pamphlet example (shown right, q.v. §Etchū Province ningyo, aka ''kairai'').

The ''ningyo'' reportedly caught in the 7th century became associated with then Prince Regent Shōtōku, and the creature has been depicted as a gift presented to him in picture scrolls entitled ''Shōtōku Taishi eden'', the oldest surviving copy of this (1069) being the earliest piece of ningyo art in Japan. There are multiple copies of the scrolls in existence. Also, much later in the 19th century. An example is the ningyo represented as a composite of the goddess Kannon and a fish (cf. §Prince Shōtoku and fig.).

The ningyo was human-headed in the 11th century anecdote involving the head of the Taira clan (cf. §Presented to Tadamori),, quoting from the anthology '' Kokon Chomonjū'' (1254), pp. 400–401

When the ex-magistrate Taira no Tadamori 平忠盛 (1096–1153) moved his residence to Beppo 別保 in the Ise 伊勢 domain.. e caughta big fish with a head similar to a man, endowed with hands, thick teeth like a fish, and a prominent mouth, which resembled that of a monkey. The body was like that of a normal fish.. (abridged)

The stranded ningyo had "four limbs" like a human or had hands and feet but was scaly and fish-headed. which were reported in Northern Japan in the 12th and 13th centuries and interpreted as omens (cf. §Omens in Michinoku) There has also been unearthed a wooden tablet with an illustration of such an ill-omened ningyo date to this period (c. 1286) (cf. )

But during the Edo period, illustrations of ''ningyo'' were varied, and in popular literature for entertainment (such as the ''kibyōshi'' genre), both human-headed fish type (armless) and half-human type with arms were illustrated (cf. §Two archetypes). One theory is that the two types derive from Classical Chinese literature, in particular the limbed ("hill-fish") and the limbless ("red ru fish") passed down from the ancient ''Shan hai jing'' ("Classic of Mountains and Seas") (cf. § Chinese ''lingyu'' and ''chiru'').

Chinese literature

However, this explanation is compromised by the fact that the Chinese "hill-fish" is considered four-limbed, and illustrated as such, whereas it was actually the Japanese work ''Wakan sansai zue'' (1712) which transformed the image of the Chinese "hill-fish" to that of a two-armed legless one (cf. fig. right), while equating it with the Japanese ''ningyo''. And this illustration has struck commentators as closely resembling the Western mermaid. (cf. § Ningyo in ''Wakan sansai zue'') The ''Wakan sansai zue'' did also give notice and print the facsimile illustration of the merfolk pronounced Teijin in Japanese (''Diren'' or in Chinese) mentioned in the classic ''Shan hai jing'', which were indeed illustrated as two-armed merfolk in Chinese sources.

Also, what the yōkai wood-block print illustrator Toriyama Sekien drew (1781, fig. left) was not a Japanese ''ningyo'' but one dwelling in the far reaches of China west of a World tree (''kenboku''; pinyin: ''jianmu'' ). The caption adds that such ''ningyo'' was also known as the people of the Di Nation.

Siren-mermaids recorded by Europeans

The Japanese Shogunate had acquired a copy of Johannes Jonston's ''Natural History'' in Dutch (1660) already by 1663, containing illustrations of the Western siren-mermaid. But it is not clear whether such "Dutch" (''Rangaku'', Western learning) images got widely disseminated in Japan before 's , which digested this and other works on the topic of mermaid, with reproduced illustrations.

By the late Edo Period (mid to late 19th century), the visual iconography of the ''ningyo'' came gradually to match the half-human half-fish of the European mermaid.

Yao Bikuni

One of the most famous folk stories involving ''ningyo'' (or rather the flesh of the human-fish), purports that a girl who ate it acquired everlasting youth and longevity, and became the nun also read Happyaku Bikuni, living to the age of 800 years.

Summary

In the typical version the girl who ate the ningyo was from Obama, Wakasa Province, and as a nun dwelled in a grass hut on the mountain at temple in the region. She traveled all over Japan in her life, but then she resolves to end her life in her home country, and sealed herself in a cave where she dwelled or has herself buried alive on the mountain at the temple, and requests a camellia tree be planted at the site as indicator of whether she still remains alive.

In a version passed down at Obama, Wakasa, the sixteen-year-old girl eats the ningyo inadvertently, after her father receives the prepared dish as a guest, so that the family is not implicated in knowingly eating the ningyo or butchering it. The Kūin-ji temple history claims the father to have been a rich man named Takahashi, descended from the founder of the province, and when the daughter turned 16, the dragon king appeared in the guise of a white-bearded man and gave her the flesh as a gift. But there are versions known all over Japan, and the father is often identified as a fisherman. A fisherman reeled in the ningyo but discarded it due to its strangeness, but the young daughter had picked it up and eaten it, according to one telling.

Time period

The oldest written sources of the legend date from the 15th century, and one of these sources relate that the appeared in Kyoto in the middle of that century (year 1449) at age 800.

Assuming age 800 in keeping with her commonly used name, her birth can be back dated to around the mid-7th century, during the Asuka Period.

Folklorist 's chronology makes her a survivor from an even older age. He dated Yao Bikuni eating ningyo flesh in the year 480 AD during the Kofun Period ( Tumulus Period).Fujisawa (1931, pub. Rokubunkan) (pub. Daitōkaku）, pp. 40–42. ''apud'' However, no written source for this could be evinced, according to a recent researcher, and an oral tradition is presumed.

Asuka period

In the 27th year of Empress Suiko (619, man-like fish were supposedly netted twice: on in Ōmi Province during the 4th month, and in Horie, Settsu Province (, an artificial canal no longer extant), according to the ''Nihon shoki''.

They were freshwater creatures, and the description of it being "childlike" suggested its true identity to be the Japanese giant salamander.

Prince Shōtoku

Crown Prince Shōtoku at age 48 was allegedly was presented with a ningyo from Settsu Province, but he abhorred the unlucky gift and ordered it to be discarded immediately. This account occurs in a picture scroll called ''Shōtoku Taishi eden''. There were some 40 copies of this made, of which the copy held by Hōryū-ji temple, dated to 1069 is the oldesg known pictorial depiction of the Japanese ningyo.

While ''Shoki'' never used the term ''ningyo'' explicitly, Prince Shōtoku had been involved in the Gamō River incident and knew to use the term, according to the prince's abridged history or . Shōtoku also knew the ''ningyo'' to bring forth disaster according to the ''Denryaku'', and an annotation provides that it was customary for fishermen at the time to release a ''ningyo'' if ever caught in the net. When the prince was alarmed by the ill omen of a ningyo appearing in Ōmi Province, he had a statue of the Kannon goddess placed in the vicinity, according to document preserved at temple.

According to the ''engi'' or foundation myth of , Prince Shōtoku met a ningyo in a pool near Lake Biwa who confessed to have been reborn in its shape due to poor deeds in past life, and the prince performed service to provide it salvation by building a temple to house a Kannon goddess statue, which was the origins of this temple.

Late Nara period

After the Asuka Period, the two oldest appearances of the ningyo are dated to the mid- to late Nara Period, and these were situated by the sea.

An ''ningyo'' beached on Yasui-no-ura in Izumo Province (a bay in present-day Yasugi, Shimane) in the Tenpyō-shōhō 8 or the year 756 AD, and later, another one appeared in in Noto Province (a peninsula in present-day Suzu, Ishikawa) in the year Hōki 9/778. These reports are preserved in a .

Heian period

Presented to Tadamori

;(Ise Province. c. 1140s. In ''Kokon Chomonjū'')
An anecdote of three presumed "ningyo" caught in a net in in Ise Province, is found in the '' Kokon Chomonjū'' ("Collection of Tales Heard, Present and Past", 1254) from the mid-Kamakura Period.

The event dates a century earlier than the anthology: when Taira no Tadamori (d. 1153; father of Kiyomori) had moved his residence to this place, populated by "bayside villagers" (fishermen).

The big fish had human-like heads (but also sets of fine teeth like fish, and a protruding mouths like a monkey's), with fish-like bodies. When hauled to land and carried (by pairs of fishermen) with the tails dragging, the creatures screamed in high-pitched voice and shed tears like a human. The tale concludes with the presumption that creatures must have been ''ningyo'' (human-fish). The three ''ningyo'' were presented to Tadamori, but one was returned to the bay's villagers (fishermen), who carved it up and ate it. It was exquisitely delicious, and no special effects came of it.

Kamakura period

Omens in Michinoku

;(Mutsu and Dewa Provinces . ''Hōjō kudai ki'', ''Azuma kagami'', etc.)

There had been frequent beachings of ''ningyo'' in Mutsu or Dewa Province (Michinoku region)
according to the (printed 1641),, and each sighting is treated as an omen, associated with some armed conflict or ill fortune which struck afterwards:

* Bunji 5 (1189) summer. Beaching at (in Mutsu). Presaging extermination of Fujiwara no Hidehira's sons
* Kennin 3, (1203), 4th month. Tsugaru-no-ura. Minamoto no Sanetomo harmed by evil zen priest.
* Kenpo 1 ( 1213). Akita-no-ura, Dewa. Same year, .
* Hōji 1 (1247). 11th day of 3rd month. Tsugaru-no-ura. Same year, 's uprising (i.e., the or bloodshed at Yuigahama）

Actually all these cases, culminating in the Hōji 1 event, were recorded in much older ''Azuma kagami'' (chronicle up to year 1266) and the ''Hōjō kudai ki'' (aka , 1331) except that the creature is not called a "ningyo" but rather a "large fish" (which was human cadaver-like with "four limbs"), or a creature "having hands and feet, covered in overlapping scales, and a head no different than a fish's". And these near-contemporary sources also interpret the ningyo ("big fish") appearances as presaging major warfare occurring within that year.

In Hōji 1 when "big fish" was beached in the northern parts (Michinoku), the waters there had turned scarlet (possibly a red tide occurrence), and this was later believed to have foreshadowed the battle which took place at the beaches Yuigahama (near Kamakura), turning the water crimson (with blood).

The Hōji 1 event was discussed in one late source, called the (published Jōkyō1/1684), but this miscopies the day to the "20th of the 3rd month", which makes it the probably direct source of Ihara Saikaku's fictional piece in which a ''ningyo'' appears.

There are additional sightings during the Kamakura Period recorded in other literature (e.g. ''kagenki'' 嘉元記)."Table 1 Records of Appearances of Ningyo 人魚の出現記録」"; ；

Ritual offering tablet

A drawings of a ningyo was found on a piece of wooden tablet excavated in the Suzaki archaeological site at Ikawa, Akita. It was discovered at the remains of a well, The tablet measures 80.6 cm×14.5 cm×0.5 cm), and dated to some time close to 1286.

The ningyo is human-headed and fish-bodied, except it has two arms and two legs alongside a finned tail. Except for the face its entirety is covered with marks which apparently represent scales. The actual animal was probably a seal, or some sort of pinniped, according to the archaeologists' report.

The inscriptions have been transcribed as "''Ara, tsutanaya, teuchi ni tote sōrō, sowaka'' (Oh, pity, but let it be killed, sowaka)" and similarly "Oh, pity, bound up like that even though a human, sowaka". Since the beast was considered ill omen, the Buddhist priest (also illustrated on the tablet) probably made offering (Buddhism) in the form of prayer, "sowaka" being a Sanskrit word often chanted at the end of the mantra.

Edo period

Alleged sightings

Shokoku rijindan

A sighting of a ''ningyo'' alleged in Wakasa Province in the Hōei (era), probably c. 1705, was recorded by in ("Stories of Common Folk rom the Provinces, 1740s). It reported had something like red cockscomb-like at the collar, which parallels what Saikaku stating in his novel (1674, cf. below) that that the ningyo possessed a cockscomb on its head.

Kasshi yawa

An mid-18th century account of a ningyo sighting was recorded by samurai daimyo essayist Matsura Seizan, in his . It occurred early part of the Enkyō era (1744–1748), and his named sources were his own uncle Hongaku-in (, ) and aunt Kōshō-in (). On their journey by sea from Hirado Domain en route to Edo, they encountered a ''ningyo'' around the Genkai Sea, in an area where no ''ama'' (female diving fishermen) could be expected to operate. It surfaced more than 10 ''ken'' (≈20 meters) ahead of the vessel, and at first, its lower half could not be seen, but its "guise was woman-like, with pale bluish hue, and light red hair which was long"; then it smiled and dove down, at which point the fish-like tail-end made its appearance, allowing the witnesses to determine it was a ''ningyo''.

Etchū Province ningyo, aka ''kairai''

The aforementioned woodblock print from Bunka 2 (1805), entitled "" publicized the appearance of a ningyo also called . It happened on the 5th month of the year, in Yokata-ura, in what is now Toyama Bay.

This ''ningyo'' was a creature with head of a long-haired young woman's, a pair of golden horns, a red belly, three eyes on each side of its torso, and a carp-like tail end, according the text of the flier. This mermaid purportedly measured 3 jō 5 shaku or .

While the printed illustration only shows one side of the ningyo, the text itself confirms it had 3 eyes on each side of the body. The feature of eyes on the torso is shared by the prediction beast '' kudan'', also known to have appeared in Etchū Province, and the ''hakutaku'' (or ''baize'', of Chinese origin), as scholars have pointed out.

The flier reports that the people grew frightened, and destroyed it with 450 rifles. Yet the flier also states that "A person who views this fish once will enjoy great longevity, avoid bad turns of events and disasters, and gain luck and virtue".

Edo popular fiction

Saikaku

The ''ningyo'' allegedly was remembered in popular tradition as having "a scarlet cockscomb on its head, and a face of a beautiful woman. Four limbs like they were wrought out of jewels, golden-gleaming scales, the flesh most fragrant, and serene voice like the skylark-whistle" according to Ihara Saikaku's ("Exemplary Tales of the Way of the Warrior", 1674), which features a ''ningyo'' as noted above.

The text describes the ''ningyo'' as being equipped with four limbs but the illustration draws a mermaid without legs, and having a tail-fin instead; she also is drawn without any cockscomb-like appendage on the head. Another discrepancy is that the samurai named Kinnai had shot the ''ningyo'' with a bow (half-bow) according to the text, but the weapon has been swapped with a firearm in the illustration.

Hakoiri musume

Santō Kyōden's . is also well known as a work during the Tokugawa era which dealt with the ''ningyo'' mermaid topic.

It is an example of work in the genre of ''kibyōshi'' or "yellow jacket", and a humorous, satirical piece, whose cast of characters include Urashima Tarō, who has an affair with a carp mistress producing a mermaid daughter in the process. The abandoned mermaid is netted by a fisherman named Heiji. To make ends meet she engages in ''miuri'', i.e., selling herself into prostitution, but her fish-bodied ''oiran'' repulses customers. After discovering that licking a mermaid imparts longevity, Heiji opens a mermaid-licking shoppe, gains great wealth, and decides to marry her. She grows out of her outer skin, metamorphosing into a full-fledged woman with both arms and legs. Heiji sells the mermaid's skin slough (''nukegara'') for profit.

Two archetypes

In the mid-Edo period, illustrations of the ''ningyo'' consisted of two broad types, as exemplified in illustrated fictional tales.

Where she is depicted as half-human with a pair of arms/hands, examples are plentiful.

She is depicted as human-headed by armless in some works, as in the case of Kyōden's ''Hakoiri musume'' just described.

Chinese ''lingyu'' and ''chiru''

The dual visual representation has been attributed to the Japanese familiarity with Chinese sources that depict both types, specifically, a human-armed type of mermaid called the and an armless (finned) type of mermaid called the .

However this formulation for explaining Chinese origin does not quite succeed, since, as its proponent points out, the Chinese ''lingyu'' is actually four-legged, as is the ''renyu'' (, "human fish") aka ''tiyu'' (; Japanese:''teigyo'') and it was the Japanese ''Wakan sansai zue'' ("Illustrated Sino-Japanese ncyclopediaof the Three Realms", 1712) which for some reason altered the image of the ningyo/renyu (aka ryōgyo/lingyu ) into a two-armed but legless mermaid.

A different commentator also regards the pictorialization of the ''ningyo'' in ''Wakan sansai zue'' to be an "addition.. with an illustration.. much like the Western idea of a mermaid".

Chinese vs. Western sources

As to the knowledge people held about the ''ningyo'' during the Edo Period, the influence of Classical Chinese literature is palpable. Even Kyōden's ''Hakoiri musume'' reveals the writer's literacy, as the work discusses the distinction between the ''teigyo'' (Chinese: ''tiyu'') and the ''geigyo'' (Chinese:''niyu'', ).

Japanese scholars writing on the ''ningyo'' drew much from Chinese sources, for example, the ''Bencao Gangmu'' (1596), the compendium of Chinese ''materia medica'', which was introduced into Japan in 1607, and was frequently quoted on the subject of the mermaid. Thus Kaibara Ekiken (1709) cited it, and distinguishes the ''teigyo'' ("ningyo" in small print) from the ''geigyo'' ("salamander").

Ningyo in ''Wakan sansai zue''

The influential ''Wakan sansai zue'' was modeled after the Three Realms encyclopedia (Sancai Tuhui, 1609) of China, and also drew from such Chinese material on the topic of ''ningyo''. But as already noted the image of the ''ningyo'' was not faithful to Chinese sources. The work also equates the ''ningyo'' with the ( zh, 鯪魚/ 陵魚, but this synonymy is based on the gloss in the Japanese lexicon ''Wamyō Ruijushō'', not Chinese sources.

Peixe muller or heiushimureru

Since the ''Wakan sansai zue'' also describes the medical use of ''peixe muller'' (Japanese transliteration: ''heishmure u', "woman fish") according to the Dutch, it was using information derived ultimately from a European. However, its claim that the woman-fish bones works as a detoxicant differs from known accounts, and stymies identification of any possible source.

A number of other Japanese scholarship on the ''ningyo'' also discussed the supposed siren-mermaid bones being trafficked by the Europeans as ''heishimureru'' (Spanish/Portuguese: ''peixe mulher''; gl, peixe muller, 'woman fish') One identifiable source was the Flemish Jesuit Verbiest ''aka'' Nan Huairen (mid-17c.) who wrote in Chinese, cited Ono Ranzan (1803), and possibly even used earlier by Kaibara Ekiken (1709), to describe the effects of the ''peixe muller'' medicine.

Ōtsuki Gentaku

In the interim, many other European works referring to the siren-mermaid were introduced to the Japanese literati: Johannes Jonston (Latin 1657, Dutch tr. 1660), Ambrose Paré (''Œuvres'', 1575; Dutch tr. 1593), and François Valentyn (1724–26, in Dutch), thanks to the efforts of 's , who gave translated digests from these works, accompanied by reproductions of siren-mermaid illustrations. And this endeavor was instrumental in forging the image/iconography of the ''ningyo'' during the era that was influenced by the European siren-mermaid.

Mummies or Feejee mermaids

Specimens of taxidermically crafted ''ningyo'' have been observed and illustrated during the Edo Period, including the painting in 'Baien gyofu'' (cf. below) and the sketch by natural historian dated Ansei 3/1856.

Baien gyofu

Mōri Baien's ''Baien gyofu'' (, 'Baien's catalog of fishes', Bunsei 8/1825) contains a full-color hand-painted illustrations of a ''ningyo'' in frontal and side views. This has been determined to represent a so-called "stuffed" ningyo crafted by joining the tail-end of a fish, also called a Feejee mermaid in the West.
