This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Kudan (Japanese)
The kudan is a supernatural being of a "prophecy beast" type, whose news or urban legend has been disseminated in Japan since the Edo Period. The human-faced, bovine-bodied kudan that allegedly appeared in "Mount Kurahashi", Tango Province in the year 1836 was reported in a contemporary kawaraban [ja].
It predicted bountiful harvest in the ensuing years, and instructed people to paste up the picture image of itself for the home to ward off evil and prosper. The kawaraban's claim that the stock phrase "as in the case/matter in question" which frequently appeared at the end of certificates/deeds, was actually a reference to this monster is considered spurious.
