Fudo is a Japanese god who is also called Acala. He is the deity of fire, wisdom and protection, but also is the patron of astrology. Fudo is a part of the “Myoo”, or “Great Kings” and is at times referred to as Fudo Myoo.
Fudo is usually depicted as an unattractive old man who is surrounded by flames, holding a sword in his right hand and a coiled rope in his left. Depiction often leaves Fudo alone, but it is not uncommon to see Fudo depicted with two attendants, sometimes even up to right.
Living in a temple upon the summit of Mount Okiyama, Fudo is surrounded by fire and people are not allowed to see him seated there.
