Sanki Daigongen (三鬼大権現)

Sanki Daigongen is attested by name in festival and shrine listings for Itsukushima (Miyajima), where gongen figures historically function as buddhas manifesting in kami form to guide people to salvation. The provided sources do not supply a narrative founding myth specific to Sanki Daigongen; rather, the name appears in the context of Itsukushima Shrine festival material (WKD Saijiki). The broader sacred landscape of Miyajima and Mt. Misen — sites associated in the sources with Kūkai (Kōbō Daishi) and with the Shingon temple Misen Daishoin — provides ritual and institutional context for named local sacred manifestations like gongen, but no primary text in the supplied material records a distinct origin tale for Sanki Daigongen itself.

The cited sources do not give an iconographic or visual description of Sanki Daigongen. The written name (三鬼) linguistically evokes "three oni," but the materials provided do not describe how, if at all, that concept is rendered in statue, painting, costume, or other shrine imagery at Itsukushima or Mt. Misen. Thus there is no documented visual depiction of Sanki Daigongen in the supplied excerpts.

There are no source-documented individual acts, miracles, or powers recorded for Sanki Daigongen in the materials provided. By category, a gongen is understood in the supplied Wikipedia definition as a buddha manifesting as a local kami "who had come to guide the people to salvation," which implies protective or salvific functions in cultic practice; however, the specific attributions, rituals, or interventions of Sanki Daigongen are not detailed in the available shrine and tourist sources.
