Rather than being a single, independent yokai, the Demons of Tateyama Jigoku are an ensemble cast constituting the underworld as projected onto the sacred Mount Tateyama. The Tateyama Mandala consists of five elements: the founding legend, hell, the Pure Land, the ascetic climbing path, and the Nunobashi Kanjō-e ritual. In the scenes of hell, it is these demons who stoke the cauldrons, herd the dead up the Mountain of Swords, and drown them in the Blood Pool[1]. Notably, Tateyama's hell was not purely a product of imagination, but was based on the actual landscape of Hell Valley—its fumaroles, sulfur springs, and desolate volcanic plains[2]. With Mikurigaike as the Blood Pool Hell and Mount Tsurugi as the Mountain of Swords Hell, the visible natural world was directly translated into the iconography of hell, giving the Demons of Tateyama Jigoku a palpable sense of reality as denizens of that very landscape[2]. The etoki preaching tours by Ashikuraji guides flourished in the late Edo period under the patronage of the Kaga domain, spreading the image of these demons to villages nationwide through the mandala[4]. The tortures inflicted by the demons of hell serve to accentuate the salvation offered by their counterparts, Ubagami and Amida Buddha. The view of the underworld in the Tateyama faith is thus constructed upon this tension between punishment and salvation.
