The Myth
Lantern Oiwa is a supernatural figure inspired by the ghost of Oiwa, a tragic character from the kabuki play Tōkaidō Yotsuya Kaidan. Oiwa suffers a terrible death as a result of her husband Iemon’s schemes and returns as a vengeful spirit. In the play’s final scenes at the Jōyama Hermitage, her ghost appears in various forms, tormenting Iemon and his companions and eventually driving them towards their deaths.
One of the best-known scenes is the lantern run. As Iemon lights a fire, the mourning lantern hanging nearby suddenly flares up, and Oiwa’s ghost emerges from within it. This striking scene became one of the play’s defining images and inspired numerous theatrical illustrations. Similar imagery also appeared in yokai-themed playing cards and sugoroku board games, where related figures were sometimes identified as Lantern Oiwa or Lantern Rock.
In Katsushika Hokusai’s One Hundred Tales, the print titled Oiwa-san depicts more than the ghost simply emerging from a lantern: the torn lantern itself transforms into Oiwa’s terrifying face. Later yokai encyclopedias began treating Lantern Oiwa as a distinct supernatural creature based on this image. In Shigeru Mizuki’s Complete Guide to Japanese Yokai, the explanation rejects the idea that Oiwa’s spirit literally rides a lantern to seek revenge. Instead, it describes a frightening phenomenon in which a lantern hanging beneath the eaves during a summer festival gradually seems to lose its shape and take on Oiwa’s dreadful face, particularly when someone is already expecting to see something frightening.
Descriptions of Lantern Oiwa are not uniform. Some accounts draw directly on Hokusai’s illustration, while others classify similar images as lantern ghosts or related supernatural lights. The figure therefore stands at the intersection of theatrical ghost stories, ukiyo-e imagery, and later yokai classification, illustrating how a famous scene from a play could develop into a separate creature in Japanese supernatural literature.
