Also known as: Seishoku Daikongou Yasha (青色大金剛薬叉)
Lit.: Blue-Faced Vajra

A deity of healing who protects against disease. He is ruler of the East and is pictured as an angry deity with blue skin (due to taking the diseases of others into himself) and four or six arms holding, variously, a vajra, a ritual staff, a wheel (symbolizing Buddha's teachings), and a noose (symbolizing the triumph of Buddhism over evil). He is a fierce protector of Buddhism and repels the calamities of evil beasts, diseases, and thunder.

Due to his healing powers, he became associated with the rituals of the Koushin beliefs.
