Dogra Magra

Dogra Magra (ドグラ・マグラ, Dogura Magura) is a novel considered the masterpiece of mystery writer Yumeno Kyusaku. Published in 1935 after more than 10 years of planning and writing, it is noted as one of Japan's "three great mysterious novels", alongside Oguri Mushitaro's The Black Death Mansion Murders and Nakai Hideo's An Offering to Nothingness. It formed the basis of a 1988 film of the same name.

In the story, the original meaning of "Dogura Magura" is explained as a dialect of the Nagasaki region, referring to the magic of Christians, priests, or as a corrupted version of "confused, taken aback" or "dōmawari, mekurami," but the details are unclear. Before this work, it was used as ruby for phantom magic and illusion in Dr. Inugami. Additionally, a woman from Saga prefecture testified that she knew that Dogura Magura was actually used as a child.
