The Japanese serow ( 氈鹿 , kamoshika, lit. "coarse pelt deer") (Capricornis crispus) [lower-alpha 1] (羚羊) is a Japanese goat-antelope, an even-toed ungulate. It is found in dense woodland in Japan, primarily in northern and central Honshu. The serow is seen as a national symbol of Japan, and is subject to protection in conservation areas.


Adult Japanese serow stand about 81 centimetres (32 in) tall and weigh 30–45 kilograms (66–99 lb). They are black to whitish, and colouring lightens in summer. The fur is very bushy, especially the tail. Both sexes have short, backwards-curving horns, and are difficult to distinguish by sight. Japanese serow are found in dense mountain forests where they eat leaves, shoots, and acorns. They are diurnal and feed in early mornings and late afternoons. Serows are solitary, or gather in couples or small family groups. The animal marks its territory with sweet-and-sour-smelling preorbital gland secretions, and males and females have separate territories that may overlap.

In the mid-20th century, the Japanese serow was hunted to near-extinction. In 1955, the Japanese government passed a law designating it a "Special National Monument" to protect it from poachers. Populations have since grown so greatly that the IUCN Red List of Threatened Animals ranks it "least concern". Complaints from foresters and farmers led in 1979 to the 1955 law's repeal. Since then, the serow has had protected status in 13 designated protected areas over 23 prefectures, and has been subject to culling as a pest outside conservation areas. Conservationists have labelled it a "living national treasure of the forest". Athletes with superior agility and speed draw comparisons with the serow, and the Yamaha Motor Company has marketed the XT 225 and its successor XT 250 dual sport motorcycle as the Yamaha Serow.


Taxonomically Coenraad Jacob Temminck first described the Japanese serow in 1836, [3] and named it Antilope crispa. John Edward Gray gave it its current name in 1846. [lower-alpha 2] Pierre Marie Heude proposed many new genera and species in a system published in 1898; Capricornis became Capricornulus, which included crispus, pryerianus, and saxicola. The system did not find acceptance. [2]

There is no fossil record of the Japanese serow; its evolutionary history and the closeness of its relation to the Taiwan serow (Capricornis swinhoei) are speculative. [4] Its taxonomic position has led to it being called a "living fossil". [5] Karyotype studies indicate it was the earliest species to split from the common Capricornis ancestor. [6] The closest relative to the Japanese serow is the Taiwan serow (Capricornis swinhoei). Genetically, there is little difference between Japanese and Taiwan serows; their karyotype is essentially the same: 2n=50, FN=60. [7] The Taiwan serow is smaller and shorter-haired, with browner fur and a white patch under the chin and throat. [8]

Phylogenetically, Capricornis is closer to goats and sheep than cattle. [7] The nomenclature and status of Capricornis taxa are not completely resolved. [1] Some researchers have considered Capricornis a junior synonym of Naemorhedus, [2] a classification that includes gorals; [1] molecular analysis has not supported this classification. [9] Capricornis has a lower canine, which Naemorhedus species usually do not. [2]

In Japan, the serow is widely thought of as a kind of deer, though deer and serows are in different families. In the past, the Japanese word kamoshika [lower-alpha 3] was written using the Chinese character for shika, meaning "deer". [lower-alpha 4] Today, when written using Chinese characters, the characters for "antelope" and "sheep" [lower-alpha 5] are used. Sometimes the serow is mistaken for a wild boar. [13]

Appearance and anatomy

The Japanese serow [10] is a small bovid [4] whose displayed morphology is primitive in relation to other bovids. It has a stocky body whose size varies little between sexes or geographic location; it stands about 70–85 centimetres (28–33 in) tall (70–75 centimetres (28–30 in) at the shoulder) [14] and weighs 30–50 kilograms (66–110 lb). [15] [16] [17] [4] The hoof is cloven. [18] Compared to mainland serow, the ears are shorter and the coat is typically longer and woollier—about 10 centimetres (3.9 in) on the body. It has a bushy tail [19] of 6–6.5 centimetres (2.4–2.6 in) [20] and no mane. [19]

Its fur is whitish around the neck, [21] and fur on the body may be black, black with a dorsal white spot, dark brown, or whitish. [4] The coat lightens in summer. [19] There are three well-developed skin glands: [22] large preorbital glands in both sexes, which increase in size as the animal ages; [14] poorly developed [14] interdigital glands in all four legs; [23] and preputial glands. [22] The adult's 32 permanent teeth form by 30 months, and have a dental formula of [22] The inner sides of the teeth become blackened with a hard-to-remove substance, likely tree resin. [24] The tongue has a V-shaped apex. [25]

Differentiation between the sexes is not well developed; [1] body size, growth, survival, and feeding habits show negligible difference. [26] Both sexes have short, [27] backwards-curving horns measuring 12–16 centimetres (4.7–6.3 in); [lower-alpha 6] the sheaths have a series of transverse rings. Horns begin to develop at about four months [25] and continue to grow throughout the lifespan. [14]

Environment affects the size of the first growth ring. Size, curvature, and thickness and number of transverse rings are indicative of age. Up to two years, there are thicker transverse rings, of greater length and flexion than in adults. Into adulthood, thinner horn rings force the thick transverse rings upward. Growth increment slows earlier in maturation in females than in males. [25] Researchers use genitalia and sexual behaviour to distinguish the sexes. [25] Females have two pairs of mammae. [4]

Hearing is sensitive [29] and eyesight is strong—the serow is able to detect and react to movement from a distance, and it can see well in low lighting. Sense of smell is also strong, and the serow can be observed raising its head and sniffing the air around it. [30]

Distribution, ecology, and behaviour

Capricornis crispus is the only wild bovine ruminant in Japan, [31] and is endemic to three of the four main islands of Japan: [10] primarily northern and central Honshu, and small areas in Shikoku and Kyushu. [10] It can tolerate colder, snowier climates better than mainland serows. [27] The animal is found solitary, in pairs, or in small family groups [1] in open grassland and forests at an elevation of about 1,000 metres (3,300 ft), [19] and uses caves to rest in. [25] It prefers temperate deciduous forest, but also lives in broad-leaved or subalpine coniferous forest [1] made up of Japanese beech, Japanese oak, [32] alpine meadow, and coniferous plantations. [1] Population density is low, at an average of 2.6 per square kilometre (6.7/sq mi), [1] and no greater than 20 per square kilometre (52/sq mi). [14]

C. crispus is philopatric [14] and territorial, [7] and marks trees with sweet-sour-smelling preorbital gland secretions to indicate its territory. [33] Males and females establish separate, overlapping ranges, typically 10–15 hectares (25–37 acres), [34] but the male's is typically larger than the female's. [14] Aggression is rare, but the serow may react with hostility to territorial breaches. [7] Due to the extinction of its once-primary predator, the Japanese wolf, the Japanese black bear is its only predator. It flees with a whistling snort when it detects danger. [27] It is an agile, sure-footed mountain dweller that is able to sprint up mountains and to jump from cliff to cliff to safety; hunters have likened this display of agility to the ninja. [35]

The diurnal [1] Japanese serow is a browser [36] that feeds in early morning and late afternoon, primarily on fleshy or coniferous leaves, plant shoots, and acorns. [1] It feeds on alder, sedge, Japanese witch-hazel (Hamamelis japonica), and Japanese cedar. [27] It adjusts its diet to what food is locally available, [37] and, as a ruminant, the serow has a four-chambered stomach. [38] Studies indicate that even severe winters have a negligible impact on the serow's food intake, suggesting that, given its solitary social structure, it selects its territory to ensure sufficient food supply. [39] Defecation occurs in set locations. [14]

Life expectancies may be up to 20–25 years. [lower-alpha 7] [40] Parapoxvirus is common, though rarely fatal; infection causes papular and nodular lesions. [25] There have been epidemics of contagious pustular dermatitis. [41] Bacteria such as E. coli and Lyme borreliosis are common, [25] and Toxoplasma gondii has been reported. [42] C. crispus is susceptible to numerous parasites, such as the nematode Trichuris discolor and the lungworm Protostrongylus shiozawai . [25]


Capricornis crispus is socially monogamous. [lower-alpha 8] [43] Females reach sexual maturity at 30 months. [1] First breeding takes place at age 2.5–3 years; breeding occurs once a year, [27] between September and January. [44] In a courtship ritual resembling that of goats or gazelles, the male Japanese serow licks the female's mouth, strikes her on the hindlegs with his forelegs, and rubs her genitalia with his horns. [19] Both sexes display Flehmen responses. [7]

Birth takes place between June and August [19] after a gestation period of about 210–220 days. [22] It takes about half an hour, and the female walks about during the birth. The single fawn is 30 centimetres (1 ft) tall and reaches adult height in a year. [27] The fawn stays with its mother for 1–2 years. It then moves gradually from its mother's range until it establishes its own. [34] Young that do not disperse on their own may be chased away by the mother. [7]

Relationship with humans

The earliest record of human contact with the serow is of a small number of prehistoric Jōmon period bones unearthed by archaeologists, primarily in mountainous regions. It is speculated the serow was hunted for its hide and for food. [45] What is believed to be the earliest written record appears in the Nihon Shoki (720): the Emperor Tenmu (r. 672–686) sent the hides of a yamashishi to senior statesmen; this yamashishi likely refers to the serow, and recurs elsewhere in the Nihon Shoki. [46]

The 8th-century Man'yōshū contains a waka poem by Kakinomoto no Hitomaro that mentions a group of shishi; a number of writers have concluded this animal is the serow, but others have pointed out the serow is normally solitary. [47] Heian period (794–1185) documents record gifts of serow horns brought to the capital. Japan's earliest extant medical work, the Daidōruijuhō  [ ja ] (808), appears to record the use of serow horn and flesh for medicinal purposes. [48]

For centuries following the Heian period, mention of the serow becomes scarce. There is some belief that it was still hunted for medicinal use. The Edo period (1603–1868) saw records increase. The Wakan Sansai Zue encyclopaedia of 1712 contains an illustrated entry on the serow. Laws prohibiting hunting  [ ja ] came into effect, but exceptions were made where animals damaged crops. [48] Following the Meiji Restoration in 1868, realistic depictions appeared of the serow, beginning with one in Keisuke Ito's Fauna Japonica (1870). [48]

Hunting and conservation

The serow has long been hunted in Japan, especially in northern Japan where, along with bear-hunting, serow-hunting was strongly associated with matagi culture. Throughout Japan's mountainous regions, the serow has been a valued catch. Its various body parts are used without waste. Prized in particular is its meat—until the mid-20th century, serow meat was so widely eaten in these regions the animal itself was known as "meat". [lower-alpha 9] Its waterproof hides were used for rafters' backflaps, its horns were ground as a preventive against diseases such as beriberi, and a cure for stomach-aches was made from the serow's small intestines and gall bladder. [49]

An animal that once inhabited deep forests far from populated areas, the Japanese serow has increasingly penetrated the outskirts of villages. [50] In western Honshū, it had become extinct by the 20th century. [1] Elsewhere, it had been hunted to such a severe degree that the Japanese government declared it a "Non-Game Species" in a 1925 hunting law. In 1934, the Law for Protection of Cultural Properties designated it a "Natural Monument Species". [lower-alpha 10] [1]

Poaching continued, leading the government to declare the Japanese serow a "Special Natural Monument" in 1955, [lower-alpha 11] [10] at which point overhunting had brought its numbers to 2000–3000. [19] Populations grew as the police put an end to poaching, and post-War monoculture conifer plantations created favourable environments for the animal. By the 1980s, population estimates had grown to up to 100,000 and serow range had reached 40,000 square kilometres (15,000 sq mi). [10] Between 1978 and 2003, its distribution increased 170%, and the population had stabilized. [1]

Conflicts with agriculture and forestry led to a 1978 repeal of the full protection the animal received under the 1955 designation. Thenceforth, 13 [lower-alpha 12] designated protection areas were established over 23 prefectures. [51] They cover about 20% of the serow range, have a total area of 11,800 square kilometres (4,600 sq mi), and range in size from 143 square kilometres (55 sq mi) to 2,180 square kilometres (840 sq mi). Culling removed 20,000 serows outside of conservation areas between 1978 and 2005. [1]

The IUCN Red List of Threatened Animals ranked the Japanese serow as "least concern" in 2008, as it has wide distribution in Japan, and a large, stable or increasing population. [1] The Law for Protection of Cultural Properties  [ ja ] [lower-alpha 13] and Wildlife Protection and Hunting Law  [ ja ] [lower-alpha 14] provide for the legal management of the Japanese serow. In 1979, the Agency for Cultural Affairs, Environmental Agency, and Forestry Agency reached an agreement on serow management measures, such as the establishment of protection areas and culling as pest control. The measures were met with resistance from conservationists, naturalist organizations, and some biologists, as the animal had previously been fully protected. A 1999 amendment to the Wildlife Protection and Hunting Law allowed prefectures to manage wildlife populations; by 2007, seven plans had been established for serow management outside of conservation areas. [1]

Foresters have raised concerns that the rising serow populations have interfered with post-War mountainside reforestation efforts, as the animal feeds on the saplings [52] of Japanese cypress, Japanese cedar, and Japanese red pine, species with commercial significance. [10] Serow have caused damage to farm crops in mountain villages, [53] and the villagers have objected to conservationists' efforts. Damage by serows to forests has been characterized in parts of Japan in criminal or martial terms: the media have referred to the problems as ningen to shika no sensō ("the war between humans and deer") and kamoshika sensō ("serow war"). [54]

Frustration with the government and conservationists led 400 foresters to launch a lawsuit in the 1980s over serow damage to timber plantations. [55] Foresters in Gifu Prefecture have justified the shooting of serows in the legs, as such shooting would not be fatal. [54] Estimating accurate population numbers has been difficult. [56] Foresters see the serow as a harmful animal, and resent government interference in controlling serow-hunting. [57] They have accused the government and wildlife experts of undercounting serows, while conservationists have counteraccused that foresters may inflate population numbers and levels of forestry damage to promote their own interests. [56]

Conservationists such as Shin Gotō believe that the increased visibility is due not to an absolute increase in populations, but to deforestation which has driven the animal further from its traditional home. [56] Serows close to populated areas may feed on farms and cypress, including saplings. [58]

Clearcutting practices may also contribute to the problem, as clearcut forests create areas of rapid herbaceous growth ideal for herbivores, who see population increases. The situation is temporary, though, and after regrowth of trees leads to the forest canopy closing over after 15–20 years, the herbivore populations are displaced as the herbaceous growth ceases to flourish. [58]

In the 1990s, as the number of young plantations decreased, so did forestry damage from serows. Concern instead turned to damage caused by sika deer, wild boars, and Japanese macaques. In Kyushu in particular, increased grazing and browsing competition from sika deer may be slowing growth of serow populations. [1]

Cultural significance

Labelled a "living national treasure of the forest", [lower-alpha 15] the Japanese serow has achieved emblematic status in Japan with national associations. It is seen as a relic species harking back to the formation of the Japanese archipelago as distinct from mainland Asia. In a symbolic gesture in 1973, the Chinese government gifted Japan a giant panda, to which the Japanese government returned two Japanese serow. Municipalities and other regions of Japan have adopted the serow as a local symbol. [60]

In Japan, the Japanese serow is most commonly known as kamoshika or kamoshishi. It has historically been given a variety of names, often based on its appearance, some of which translate as "mountain sheep", "wool deer", "nine tail cow", and "cow demon". Regional names abound, some of which translate as "dancing beast", "foolish beast", or "idiot". Japanese people often characterize the serow as "weird" or "abnormal", and it is seen as a "phantom animal" as it tends to live alone in the depths of distant forests, and appears to observe forest workers from areas high in the mountains. [61]

The serow has a reputation in Japan for its speed and agility. Superior athletes are compared to the serow, as it is known not only for its agility, but also its sprinting ability. The Yamaha Motor Company has marketed the XT 225 sport motorcycle as the Yamaha Serow. In Japanese, the word ochiru means both "to fail an exam" and "to fall"; as the serow is known for its sure-footedness on mountain cliffs, students can buy omamori charms marked with a serow hoofprint in the hope it will help them pass exams. [35]

The term antelope refers to numerous extant or recently extinct species of the ruminant artiodactyl family Bovidae that are indigenous to most of Africa, India, the Middle East, Central Asia, and a small area of Eastern Europe. Antelopes do not form a monophyletic group, as some antelopes are more closely related to other bovid groups, like bovines, goats, and sheep, than to other antelopes.

<span class="mw-page-title-main">Four-horned antelope</span> Small antelope from Asia (Tetracerus quadricornis)

The four-horned antelope, or chousingha, is a small antelope found in India and Nepal. Its four horns distinguish it from most other bovids, which have two horns. The sole member of the genus Tetracerus, the species was first described by French zoologist Henri Marie Ducrotay de Blainville in 1816. Three subspecies are recognised. The four-horned antelope stands nearly 55–64 centimetres (22–25 in) at the shoulder and weighs nearly 17–22 kilograms (37–49 lb). Slender with thin legs and a short tail, the four-horned antelope has a yellowish brown to reddish coat. One pair of horns is located between the ears, and the other on the forehead. The posterior horns are always longer than the anterior horns, which might be mere fur-covered studs. While the posterior horns measure 8–12 centimetres (3.1–4.7 in), the anterior ones are 2–5 centimetres (0.79–1.97 in) long.

The saola, also called spindlehorn, Asian unicorn, or infrequently, Vu Quang bovid, is one of the world's rarest large mammals, a forest-dwelling bovine native to the Annamite Range in Vietnam and Laos. It was described in 1993 following a discovery of remains in Vũ Quang National Park by a joint survey of the Vietnamese Ministry of Forestry and the World Wide Fund for Nature. Saolas have since been kept in captivity multiple times, although only for short periods as they died within a matter of weeks to months. The species was first reported in 1992 by Do Tuoc, a forest ecologist, and his associates. The first photograph of a living saola was taken in captivity in 1993. The most recent one was taken in 2013 by a movement-triggered camera in the forest of central Vietnam. It is the only species in the genus Pseudoryx.

<span class="mw-page-title-main">Blackbuck</span> Antelope native to India and Nepal

The blackbuck, also known as the Indian antelope, is a medium-sized antelope native to India and Nepal. It inhabits grassy plains and lightly forested areas with perennial water sources. It stands up to 74 to 84 cm high at the shoulder. Males weigh 20–57 kg (44–126 lb), with an average of 38 kg (84 lb). Females are lighter, weighing 20–33 kg (44–73 lb) or 27 kg (60 lb) on average. Males have 35–75 cm (14–30 in) long corkscrew horns, and females occasionally develop horns, as well. The white fur on the chin and around the eyes is in sharp contrast with the black stripes on the face. Both sexes' coats feature a two-tone colouration; in males, the majority of the body is dark brown to black, with white circles around the eyes, white ears and tail, and the belly, lower jaw, and inner legs also white. Females and juveniles are yellowish-fawn to tan and display the same white areas, only with more of a beige tone than the males. Females also feature a more pronounced horizontal white side-stripe, starting around the shoulder and ending at the rump. The blackbuck is the sole living member of the genus Antilope and was described by Carl Linnaeus in 1758. Two subspecies are recognized.

While this is the only member in the genus Ourebia, eight subspecies are identified. The oribi reaches nearly 50–67 centimetres (20–26 in) at the shoulder and weighs 12–22 kilograms (26–49 lb). It possesses a slightly raised back, and long neck and limbs. The glossy, yellowish to rufous brown coat contrasts with the white chin, throat, underparts and rump. Only males possess horns; the thin, straight horns, 8–18 centimetres (3.1–7.1 in) long, are smooth at the tips and ringed at the base.

India is home to a large variety of wildlife. It is a biodiversity hotspot with various ecosystems ranging from the Himalayas in the north to the evergreen rainforests in the south, the sands of the west to the marshy mangroves of the east. India lies within the Indomalayan realm and is home to about 7.6% of mammal, 14.7% of amphibian, 6% of bird, 6.2% of reptilian, and 6.2% of flowering plant species. India's forests contain about 500 species of mammals and more than 1300 bird species.

The wildlife of Japan includes its flora, fauna, and natural habitats. The islands of Japan stretch a long distance from north to south and cover a wide range of climatic zones. This results in a high diversity of wildlife despite Japan's isolation from the mainland of Asia. In the north of the country, north of Blakiston's Line, there are many subarctic species which have colonized Japan from the north. In the south there are south-east Asian species, typical of tropical regions. Between these areas lies the temperate zone which shares many species with China and Korea. Japan also has many endemic species that are found nowhere else in the world, making it home to many endangered/rare species.

The Kingdom of Bhutan is a small, landlocked nation nestled in the southern slopes of the Eastern Himalaya. To its north lies the Tibet Autonomous Region of China and to the west, south and east lies the Indian states of Sikkim, Bengal, Assam and Arunachal Pradesh.

<span class="mw-page-title-main">Red serow</span> Species of mammal

The red serow, also called the Burmese red serow, is a goat-antelope thought to be native to southern Bangladesh and northern Myanmar. It has been sometimes been considered a subspecies of C. sumatraensis. In the northeastern part of India, the red serow occurs widely in the hills south of the Brahmaputra river. although the IUCN states that this species is recorded with certainty only from Myanmar, in Kachin State, and that records in India refer to the Himalayan serow.Serow in South and Southeast Asia are threatened by habitat destruction, poaching, and disease transmission from domestic livestock. Myanmar and India face severe poaching issues despite legal protections.

<span class="mw-page-title-main">Himalayan serow</span>

The Himalayan serow, also known as the thar, is a subspecies of the mainland serow native to the Himalayas. It was previously considered its own species, as Capricornis thar. It is the official state animal of the Indian state of Mizoram.

<span class="mw-page-title-main">Pronghorn</span> Species of North American hoofed mammal

The pronghorn is a species of artiodactyl mammal indigenous to interior western and central North America. Though not an antelope, it is known colloquially in North America as the American antelope, prong buck, pronghorn antelope and prairie antelope, because it closely resembles the antelopes of the Old World and fills a similar ecological niche due to parallel evolution. It is the only surviving member of the family Antilocapridae.

<span class="mw-page-title-main">Preorbital gland</span> Paired exocrine gland in many hoofed animals

The preorbital gland is a paired exocrine gland found in many species of artiodactyls, which is homologous to the lacrimal gland found in humans. These glands are trenchlike slits of dark blue to black, nearly bare skin extending from the medial canthus of each eye. They are lined by a combination of sebaceous and sudoriferous glands, and they produce secretions which contain pheromones and other semiochemical compounds. Ungulates frequently deposit these secretions on twigs and grass as a means of communication with other animals.

Protostrongylus shiozawai is a parasitic nematode that belongs to the family Protostrongylidae. Japanese serows are the only animals known to be infected with Protostrongylus shiozawai. P. shiozawai is a parasite that targets the bronchioles, alveolar ducts, and alveoli of the Japanese serow.

Kahilu Wildlife Sanctuary is a protected area in Myanmar's Kayin State. It was established in 1928 and covers 160.58 km2 (62.00 sq mi). It is mostly flat with elevation ranging from 20 to 260 m. Annual precipitation is about 3,800 mm (150 in).
