Wakan Sansai Zue
One century after the "Wakan Sansai Zue" in the 19th century and afterwards in Japan, as the first to speak of them, they were mentioned in Shūkichi Arai's literary work "Fushigi Benmō", stating, "the corpses of those who are buried have their phosphorus turned into onibi". This interpretation was supported until the 1920s, and dictionaries would state this in the Shōwa period and beyond.
