Case files — Asia

1. The Himalayas — the yeti / migoi / bun manchi — reported for centuries

Rating: A (tested) · Status: tested, reconciled as bears

• Reported: a large bipedal, hair-covered creature of the high mountains of Nepal, Tibet and Bhutan. Regional names differ (Sherpa yetii; Nepali bun manchi, "jungle man"; Bhutanese migoi). Footprint records reach back to at least 1899 (Waddell, Among the Himalayas); the 1921 Everest reconnaissance party's footprint report is the source of "Abominable Snowman".
• Evidence tested: nine purported yeti specimens (bone, tooth, skin, hair, faeces) sequenced by Lindqvist et al., Proc. R. Soc. B 2017 → one dog, one Asian black bear, one Himalayan brown bear, six Tibetan brown bears. The monastic hand/paw relic: Asian black bear. The Tibetan cave femur: Tibetan brown bear.
• Earlier, weaker testing: Bryan Sykes' 2014 work reported a sample with affinity to an ancient polar bear; the 2017 study re-assigned that specimen to a Himalayan brown bear. Messner concluded the same from the mountain side in 1986.
• Official involvement: Bhutan's Sakteng Wildlife Sanctuary (742 km², established 17 April 2003) exists in part to protect migoi habitat; Nepal's 1959 permit regime (capture, don't kill, hand over photographs and reports) is recorded in a US Foreign Service despatch in the National Archives.
• Leading conventional explanation: bears — Himalayan brown, Tibetan brown, Asian black — seen standing, at distance, in bad light, at altitude, with a human observer's expectation doing the rest. The 2017 paper's own framing: "the biological underpinnings of the yeti legend can be found in local bears." Note the conservation twist: the bears at issue are themselves endangered.

2. Shennongjia, Hubei, China — the yeren — 340 BCE texts; state expeditions 1976–81

Rating: C (reported) with a documented official phase · Status: state-investigated, evidence resolved to known animals

• Reported: a "wild man" (野人, yěrén) — tall, hairy, upright, said to raid villages. Textual tradition from Qu Yuan's Jiu Ge (340–278 BCE) and the Yi Zhou Shu/Erya (4th–3rd c. BCE, the feifei), through Tang-dynasty reports, to a dense modern record in the Shennongjia Forestry District.
• The state phase: after 1976 the Chinese Academy of Sciences launched large expeditions examining eyewitness accounts, footprints, hairs and alleged bodies — a 1977 Shennongjia expedition included military personnel, zoologists, biologists and photographers; by 1984 the NYT counted four scientific expeditions. The period is known in China as "yeren fever", and it relied unusually heavily on citizen reports.
• Outcome: all forwarded evidence came from known animals — bears, monkeys and gibbons; Zhou Guoxing's review records fibres that "were not even animal hair" and wildmen that, when killed and eaten, were bears. Interest waned by the late 1980s. No serious scientific institution recognises such apemen today.
• What survives: the yeren campaign fed the creation of the Shennongjia National Nature Reserve (1983) and is now provincial tourism — a female yeren and child statue stands in the reserve. The creature was also used in post-Cultural-Revolution writing about deforestation and conservation.

3. Mongolian and Central Asian almas — attested in Mongol, Turkic and Iranian traditions

Rating: C (reported) · Status: reported only; a Soviet state commission examined the wider question

• Reported: a human-sized, hair-covered "wild man" of the Altai, Tian Shan, Pamirs and Caucasus, described as a primitive human rather than an ape — no speech, no fire, no tools. The name is embedded in Mongolian place names (Almasyn Dobo, "Hills of Almases") and a name-avoidance taboo in Övörkhangai and Bayankhongor, where the beings are called akhai ("uncle-brother"). Przhevalsky's 19th-century travel writing is an early record.
• The official phase: the Soviet Academy of Sciences "snowman" commission, established in the 1950s during the abominable-snowman flap, largely at the instigation of the historian Boris Porshnev, who lobbied for and collected almas testimony for decades. Academic analysis treats it as a Cold War science-politics episode in which Soviet scientists engaged publicly with the phenomenon in ways Western institutions did not.
• Leading explanation: the reported profile (human-shaped, tool-less, speechless) plus the absence of any specimen suggests a mix of bear misidentification, feral-human folklore, and oral tradition layered over real encounters with reclusive people and animals. Central Asia remains the least surveyed region in this pack — the honest statement is that the case is open because nobody is looking, not because the looking has failed.

4. Kerinci Seblat, Sumatra, Indonesia — orang pendek — reported for 100+ years

Rating: C (reported) · Status: reported only; extensive fieldwork, no specimen

• Reported: a small (80–150 cm) ground-dwelling, bipedal, short-furred primate in the forests of central Sumatra, especially Kerinci Seblat National Park. Suku Anak Dalam and other forest communities are the origin of most testimony; Dutch colonists, then Western scientists, added records through the twentieth century.
• Fieldwork on file: from the late 1980s, Debbie Martyr spent around fifteen years interviewing witnesses and running camera traps; she reported a personal sighting in 1990. Expeditions by conservation organisations (FFI and others) searched the Kerinci forests. Camera traps produced no photograph of the animal, though they documented tigers and other wildlife.
• The adjacent real science: the region's genuine surprise is that a new orangutan species — the Tapanuli orangutan, Pongo tapanuliensis — was described in 2017 from an isolated Batang Toru population by genomic, morphometric and behavioural evidence. It is a reminder that Sumatra can still produce a new great ape when someone does the genetics; it is also a reminder that the last one was found by sequencing a skeleton, not by camera traps.
• Leading explanation: sightings likely combine misidentified sun bears (which can stand and are locally common), gibbons and siamangs moving on the ground, and possibly a real surviving population of an unknown small ape. Both readings are live; neither has a specimen.

5. Shimokitayama, Nara (and Yoshii, Okayama), Japan — tsuchinoko — 1980s wave

Rating: D (explained) · Status: no specimen; bounties expired

• Reported: a short, thick, "hammer-child" snake (30–80 cm), wider at the middle than the head or tail, reputed to jump, roll like a hoop, speak, lie, and drink alcohol. Name traditions differ by region (bachi hebi in the northeast).
• The 1980s wave and the money: sightings concentrated in Shimokitayama village, Nara. In 1988 village councillor Kazuo Nozaki launched a "Tsuchinoko Expedition" offering ¥1,000,000 for live capture and ¥300,000 for a skin sample. Chikusa (Hyōgo) offered ¥2,000,000 (void after municipal merger); Yoshii (Okayama) offered ¥20,000,000. Popular retellings inflate these to ¥100 million; the sourced record does not support that.
• Outcome: no specimen. Bones found in Yoshii in May 2000 generated publicity and did not resolve to the animal. The likely basis is misidentified common snakes — notably hognose snakes, which flatten and roll when threatened — with folklore supplying the rest.

6. Lake Ikeda, Kagoshima, Japan — Issie — reported since the Meiji era

Rating: C/D (reported, lean explained) · Status: reported only; eels on file

• Reported: a saurian lake monster in Kyūshū's largest lake (11 km²). A mare-and-foal legend underpins the local name.
• The instrument angle: during a 1961 sonar search for a crashed US military jet, a large contact was reportedly recorded — hobbyist-tier sourcing only, so flagged rather than asserted.
• The mundane candidate on file: Lake Ikeda is known for large eels, some six feet long. A 1998 benthic survey found essentially no zoobenthos. The lake's transparency fell from 26.8 m to about 5 m after 1965 river diversions — a reminder that ordinary limnology keeps producing the same answer the Loch Ness eDNA work did.
