Iyaya (Negaya)Sekien Iconography Standard

Adheres strictly to Toriyama Sekien’s image and notes, avoiding later embellishments. The yokai is shown as the back view of a young woman standing by water, while the surface reflects the visage of an old man. The name draws on Dongfang Shuo’s “kaizai” expressions of wonder, suggesting Sekien likely fashioned an allegory. Youth and age, beauty and ugliness, front and back are opposed within a single frame, read as a design warning against being deceived by appearances. Firm oral traditions are scarce, so its character is defined largely through image interpretation. The readings iyaya or iyami vary by source, possibly evoking refusal or repulsion akin to “no,” but the literature offers no certainty.
