Satori are strange mythical intelligent ape-men found in the mountains of japanese prefecture Gifu. The are roughly man-sized, and appear similar to larger versions of the native monkeys found in the region.

Satori appear to travelers on mountain roads, or folks living in mountain huts far from civilization. If the opportunity presents itself, they gladly dine on anyone they can get their hands on. In cases where they encounter a lone human female, they often take her away into the mountains and rape her. Satori are most well known for their uncanny ability to read people’s minds and then speak their thoughts faster than the individuals can get the words out themselves. This makes it very difficult to hunt, trick, or escape from a hungry satori. However, should something unforeseen happen, such as being unexpectedly hit by an object, satori grow very frightened and run away. One of the only ways to avoid being eaten by one of these yokai is to completely empty one’s mind; with no mind to read, the satori grows bored and wanders away.

The name satori literally means "enlightenment" in the Buddhist sense. The satori, with its uncanny ability to read thoughts, comes across as a kind of enlightened being to scared travelers, which is how it got its name. This also relates to the method of escaping a satori — true enlightenment comes from emptying one’s mind of distracting, worldly thoughts, just as salvation from the hungry satori comes from an empty, zen-like mindset.

The origin of the satori is not entirely clear. Edo-period encyclopedias relate satori with yamako, apes from western China and captures women to rape or to eat. It has also been theorized that satori are cousins of yamabiko, a small monkey-like yokai. The satori’s ability to read people’s minds and the yamabiko’s ability to mimic their words are rooted in the same folklore. More recent folklorists have suggested that satori are fallen mountain gods of the ancient proto-Shinto religion which have been corrupted into yokai over the ages.
