This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Satori (Japanese)
Satori in Japanese folklore are mind-reading monkey-like monsters said to dwell within the mountains of Hida and Mino. People are said to meet them while walking along mountain paths or resting in the mountains. Upon reading a person's mind, the satori would say the person's thoughts aloud faster than a human could. There is also a theory that they are the child incarnations of mountain gods who have come to ruin and turned into a yokai form.
They would appear before people at mountain huts, and are even said to try to eat and kill if they have a chance, but if something unexpectedly strikes the satori, they become stricken with fear and run away. There is also a theory that they do not present any danger to people and would not dare to harm those who work on the mountain, allowing people to coexist with satori.
