An oni that appears at Rashomon Gate and on the outskirts of the capital, serving to highlight a warrior’s valor. Medieval war tales and Noh plays preserve multiple versions with differing stages and details, but the core remains: a lone warrior meets an oni at a gate or bridge and severs its arm. The arm is treated as a symbol of impurity and numinous power, leading to later tales of its recovery. Its conflation with Ibaraki-dōji intensified in early modern retellings, shifting names and locales, yet overall it embodies a liminal threat haunting the edges of the capital. Iconography shows an iron staff, horns, red-black skin, and wild hair, often set amid stormy weather and black clouds. Representations rooted in warrior lore, Noh, and picture scrolls continue to shape its image today.
