Tsushima Ōkami is a Shinto deity enshrined chiefly at Tsushima Shrine in Aichi Prefecture, historically venerated as a guardian against plague and epidemic illness. Devotees have long turned to this kami in hopes of protection from disease and for the maintenance of communal health, particularly during outbreaks of infectious sickness in premodern Japan. The deity's cult reflects a broader tradition of shrine worship focused on purification and safeguarding against pestilence.
