Yakujin Myoo is venerated within Japanese esoteric Buddhist tradition as a wrathful guardian figure, associated with the Myoo class of deities who serve to protect the Dharma and practitioners from obstacles and defilements. Figures of this type are traditionally invoked in rites of purification and exorcism, their fierce countenance understood not as malevolence but as a manifestation of compassionate power meant to subdue negative forces and spiritual impurity. Specific historical and iconographic details about Yakujin Myoo are less widely documented than those of the major Five Great Myoo, so accounts of this figure's particular attributes should be approached with appropriate caution.
