Sakushimaさくしま

This version focuses on the process of retelling through which modern yokai encyclopedias have shaped this apparition. The primary source preserves only the bare structure: "it comes softly, slips over the person, and suffocates them." Postwar yokai encyclopedias, including lines descending from Mizuki Shigeru's Nihon Yōkai Taizen and illustrated references edited by Kyōgoku Natsuhiko and Tada Katsumi, took that single sentence as a starting point and added details such as "a futon that feels light gradually becomes heavy" or "it falls silently while the person is asleep." These are later embellishments not grounded in the primary record. At the same time, they work well as a way to convey to modern readers the nighttime bodily sensations of a fishing village: the weight of bedding dampened by sea wind, sleep paralysis from exhaustion, and the cold dampness of the tide creeping in from the sea. The fact that it has no counterpart in Toriyama Sekien - a modern coastal-folklore apparition that does not fit inside Edo picture-scroll yokai - has also left later artists and writers room to imagine its form freely. That openness is part of Futon-kabuse's modern character.
