Here is a list of mythical creatures beginning with this letter and I am constantly gathering information from each continent and continually updating.
Azukibabaa (Japanese)
Azukibabaa (the bean hag) is a monster from Miyagi prefecture to the Kanto region. This is an old woman's yokai that makes the sound of adzuki, just like Azukiarai. There is a theory that, instead of a different type of red bean-washing monster, the true nature of red bean washing is called "Azuma-gama" in some areas.
The people of Miyagi Prefecture tell of a much more sinister member of the azuki family and rather than the benign and cute azuki arai known throughout the country, this northeastern variation takes the form of a fearsome old hag dressed all in white, singing in a husky, ugly voice. Azuki bab? appear only at twilight—particularly on rainy or misty autumn nights.
