Kakuen

What it is

The kakuen, or jue yuan, is a legendary animal found in the folklore of China and Japan. It is described as a large, dark blue ape that stands about 1.6 meters tall and walks on two legs like a human. Ancient medical and supernatural texts describe it as an old monkey that has lived for centuries. The creature is primarily known for its habit of kidnapping human women from mountain villages. These women are taken as wives and forced to bear children with the beast.

Where it comes from

The creature appears in several classical Chinese works. The Bencao Gangmu describes it as an aged monkey with a dark blue hue that can walk like a person. Other texts, such as the Baopuzi, suggest it is the result of a rhesus monkey living for hundreds of years. The In Search of the Supernatural places these beings in the mountains of southwest Shu. Later Japanese encyclopedias from the Edo period adopted the concept, linking it to local mountain spirits known as yamako.

How it is done

The kakuen is said to distinguish between men and women by scent. It targets solitary women passing through mountain paths or living near streams. After abduction, the women are kept in the mountains. If they fail to produce children, they are not allowed to leave and eventually lose their human will and appearance. Those who give birth may return to human villages with their children, though they often raise them out of fear for the child's survival if left alone.

Peoples and places

In China, the kakuen is linked to the origin of the Yang surname in southwest Shu, with tales claiming many locals are descendants of these unions. In Japan, the creature was associated with yokai such as the kuronbō. These were described as black, hairy, monkey-like beings that could understand human speech and read minds. Artists like Sekien Toriyama depicted the kakuen under the name satori, illustrating its role in Japanese supernatural lore during the Edo period.

What people believe

Folklore holds that the kakuen lives for thousands of years, evolving from smaller monkeys over centuries. The creatures are said to possess no females of their own, necessitating the abduction of human women. A specific tale recounts a kakuen disguising itself as a ferryman to help people cross a river. When attacked by a suspicious traveler, the beast revealed its true form and emitted a foul odor when burned, confirming its supernatural nature.

How scholars and sceptics see it

Modern scholars and cryptid enthusiasts have noted similarities between the kakuen and the yeren, a Chinese apelike cryptid. Historians trace the evolution of the myth from Chinese medical texts to Japanese yokai encyclopedias. The connection between the Chinese jue yuan and the Japanese kuronbō is debated, with some noting textual references while others argue the link is not conclusive.

Compare and confuse

The kakuen shares traits with the chóu, a western mythical creature that kidnaps men instead of women. Both are monkey-like beings that bridge human and animal worlds through abduction. In Japan, the kakuen is often compared to the satori and kuronbō, which are also mountain-dwelling, intelligent, and elusive creatures.
